Section 1: INTRODUCTION
1.1 Purpose of This Document
This Chemical Hygiene Plan is a document designed to express the policies and procedures
adopted by Farmingdale State College (the “College”) as they relate to the safe operation of
laboratories using chemicals. The Chemical Hygiene Plan is derived from the Laboratory
Standard, a regulation promulgated in the January 31, 1990, issue of the Federal Register. The
goal of the Laboratory Standard is to provide a safe laboratory workplace, and it includes
requirements on occupational exposures to hazardous chemicals.
The Occupational Safety and Health Administration (OSHA) Laboratory Standard requires that
employers protect workers through the development and implementation of a Chemical Hygiene
Plan tailored to the individual laboratory workplace. The purpose of the Laboratory Standard and
of this Chemical Hygiene Plan is to protect employees from harm due to exposure to hazardous
chemicals while they are working in the laboratory.
Many policies and practices may not be part of the Chemical Hygiene Plan, and yet they are
crucial to the planning process that must be part of maintaining a safe environment for employees
and students. It is therefore incumbent upon each employee to maintain a safety conscious
approach to their daily work activities, particularly those within a laboratory.
1.2 Application of the OSHA Laboratory Standard
The Occupational Safety and Health Act is administered by the Occupational Safety and Health
Administration, which is part of the Department of Labor. OSHA promulgated regulations are
found in the Code of Federal Regulations (CFR), Title 29, Section 1910 (cited as 29 CFR 1910).
Appendix A of this document contains the full text of 29 CFR 1910.1450, “The Laboratory
Standard,” and this introduction contains a summary of that code. Farmingdale State College is
regulated by the New York State Department of Labor (NYSDOL) and the New York State
Division of Safety and Health (NYSDOSH).
What is covered by the Laboratory Standard?
This standard applies to employers engaged in laboratory use of hazardous chemicals.
“Laboratory” means a facility where the “laboratory use of hazardous chemicals” occurs. It is
a workplace where relatively small quantities of hazardous chemicals are used on a non-
production basis.
“Laboratory use of hazardous chemicals” means handling or use of such chemicals in which all
of the following conditions are met:
1
Chemical manipulations are carried out on a “laboratory scale” (i.e., work with substances in
which the containers used for reactions, transfers, and other handling of substances is
designed to be easily handled by one person);
Multiple chemical procedures or chemicals are used;
The procedures involved are not part of a production process, nor do they in any way
simulate a production process; and
“Protective laboratory practices and equipment” are available and in common use to
minimize the potential for worker exposure to hazardous chemicals.
A “hazardous chemical” is a chemical for which there is statistically significant evidence (based
on at least one study conducted according to established scientific principles) that acute or
chronic health effects may occur in exposed employees, or if it meets one or more of the
following:
Any chemical which is a physical hazard or a health hazard (OSHA 29 CFR 1910.1200(c)) or
29 CFR 1910.1450(b));
Any chemical for which there is scientifically valid evidence that it is a combustible liquid, a
compressed gas, explosive, flammable, organic peroxide, pyrophoric, unstable (reactive), or
reacts violently with water;
Any chemical, for which there is statistical evidence based on at least one study conducted in
accordance with established scientific principles that acute or chronic health effects may
occur in exposed employees, is classified as a health hazard. Health hazards include
chemicals that are carcinogens, toxin or highly toxic agents, reproductive toxins, irritants,
corrosives, sensitizers, hepatotoxins, nephrotoxins, neurotoxins, agents which act on the
hematopoietic systems; and agents that damage the lungs, skin, eye or mucous membranes as
defined in 29 CFR 1910.1200, Appendix A;
Any chemical, for which the evaluation performed by the chemical manufacturer/importer, as
listed on the Safety Data Sheet (SDS), indicates it is hazardous;
Any chemical listed in OSHA, 29 CFR 1910 Subpart Z, "Toxic and Hazardous Substances"
or Environmental Protection Agency (EPA), 40 CFR Part 261 "Identification and Listing of
Hazardous Waste.";
Any chemical listed in the "Threshold Limit Values for Chemical Substances and Physical
Agents in the Work Environment", American Conference of Governmental Industrial
Hygienist (ACGIH) (latest edition) or "The Registry of Toxic Effects of Chemical
Substances", NIOSH (latest edition);
Any chemical regulated by the U.S. Department of Transportation, 49 CFR, Subchapter C,
Parts 171-172;
Any chemical that is capable of causing environmental or health damage if disposed of
improperly as specified in the U.S. Environmental Protection Agency, Title 40 Code of
Federal Regulations (Resource Conservation and Recovery Act); and
Any mixture untested as a whole to determine whether it is a physical or health hazard is
assumed to present the same physical or health hazard as the individual components that
compromise one percent or greater (by weight or volume) of the mixture. An exception is the
mixture shall be assumed to present a carcinogenic hazard if it contains a component which is
considered to be a carcinogen in concentration of 0.1 percent or greater.
2
“Employees” who must abide by this Chemical Hygiene Plan are individuals employed in the
laboratory workplace who may be exposed to hazardous chemicals in the course of their
assignment. Included are employees who work in the laboratory such as instructors and technical
support, and other employees of the College who routinely enter the laboratory to perform their
assigned responsibilities, such as maintenance and janitorial personnel.
What Is Not Covered by the Laboratory Standard?
Any hazardous chemical use which does not meet this definition is regulated under other
standards. This includes other hazardous chemical use within a laboratory. For instance:
Chemicals used in building maintenance of a laboratory are not covered under the Laboratory
Standard.
The production of a chemical for commercial sale, even in small quantities, is not covered by
the Laboratory Standard.
Quality control testing of a product is not covered under the Laboratory Standard.
The laboratory Standard is a regulation promulgated for the protection of employees. Since
students are not employees, they are not officially covered by provisions of the Chemical
Hygiene Plan. However, since this document contains guidance on generally accepted good
laboratory practice, it should be used to establish minimal safety instruction and
procedures for students.
Additionally, laboratory visitors, such as sales staff, outside repair persons, and guests are not
included in the definition of employee and thus do not need to be addressed in the Chemical
Hygiene Plan.
1.3 Summary of the Chemical Hygiene Plan
In compliance with the Laboratory Standard, the College has prepared and implemented this
Chemical Hygiene Plan (the “Plan”). Adherence to the Plan will assure that employees will be
protected from health hazards associated with hazardous chemicals in the laboratory, and
exposed to regulated substances at a level that will not exceed the permissible exposure limits.
This Chemical Hygiene Plan is composed of the following sections:
This introduction which states the goal and basis for the Chemical Hygiene Plan.
A list of the College personnel responsible for various aspects of the Plan and its
implementation.
General principles which outlines the guidelines for working with laboratory chemicals.

Section 2: COLLEGE ORGANIZATION
The continuing execution of the provisions of the College’s Chemical Hygiene Plan is a
responsibility of all employees who are involved in the laboratory science program. However,
certain employees and entities are specifically charged with the successful execution of the
Chemical Hygiene Plan.
2.1 President or Chief Executive Officer
The President, as Chief Executive Officer, has the ultimate responsibility for chemical hygiene
within the College. The President should, with other administrators, provide continuing support
for College-wide chemical hygiene programs, including the development and enforcement of the
Chemical Hygiene Plan.
2.2 Dean
In each school, the Dean or other administrative head is responsible for chemical hygiene
programs at that location. The Dean should monitor compliance with the Chemical Hygiene
Plan.
2.3 Project Director
Some situations may require a Project Director, who may be a department head, professor, or
someone from outside the normal school structure who has a particular responsibility related to
the laboratory, but who is not part of the regular teaching or instructional responsibilities. The
project director has specific responsibilities requiring work in the laboratory, which is not done
as part of a regular class. The project director has the primary responsibility for chemical
hygiene procedures for that project.
2.4 College
The responsibilities of the College, which is the employer of record, include the following:
Appointing a Chemical Hygiene Officer and assigning the Chemical Hygiene Officer the
various responsibilities outlined below:
Making manufacturer’s safety data sheets (SDS’s) accessible to employees.
Providing employees with training and information regarding chemical and physical
hazards.
Posting “Designated Areas” if any select carcinogens, reproductive toxins, or acute
toxins are used in the laboratory.
Measuring the concentration of hazardous chemical(s), if there is any reason to
believe that the action level has been exceeded.
6
Keeping records of employee exposure to hazardous chemicals for a period of 30
years beyond the time of exposure. These records should be filed by the employee,
with the College, in writing, within two weeks of the exposure.
Facilitating medical consultations and examinations required as a result of exposure
to hazardous chemical(s).
Ensuring a Respiratory Protection program is in place and that employees are
provided respirators when necessary.
2.5 School Employees
All employees who normally work in a laboratory area are responsible for:
Participating in training programs provided by the College.
Maintaining awareness of health and safety hazards.
Planning and conducting each operation in accordance with the College’s chemical hygiene
procedures.
Consulting reference materials, including safety data sheets, related to chemical safety
whenever appropriate.
Using good personal chemical hygiene habits.
Reporting accidents, injuries, unsafe practices, and unsafe conditions.
2.6 Chemical Hygiene Personnel
The Farmingdale State College Chemical Hygiene Officer is appointed by the President. The
Environmental Health & Safety Officer will serve in this position for the College unless
otherwise designated, in which case this Plan will reflect such change.
The Chemical Hygiene Officer will report to the Vice President and Chief Financial Officer or
his designee.
The responsibilities of this position require the Chemical Hygiene Officer to:
Develop and implement the Chemical Hygiene Plan and the safety program for the College,
including training, reporting, and other functions noted here.
Work with administrators and teachers to develop and implement the safety program.
Monitor the use and disposal of chemicals used in the schools’ laboratory programs.
Assure that inspections of equipment and space in the laboratory are performed when
appropriate and that records of inspections are maintained.
Provide technical assistance to employees on the Chemical Hygiene Plan.
Assure that the Chemical Hygiene Plan is reviewed annually and revised as needed, so that it
is always in compliance with current legal requirements.
Make decisions regarding requests to use chemicals identified as explosive, carcinogenic,
mutagenic, highly toxic, or otherwise unsuitable for general school laboratories.
Determine the need for personal protective equipment beyond that specified for general
laboratory use.
7
Implement appropriate training with regard to chemical hygiene for all employees whose
normal work locations include laboratory areas.
2.7 Students
Students are not specifically covered by the Laboratory Standard. However, good personal
chemical hygiene habits should be taught to all students at every reasonable opportunity,
particularly to those who use the laboratory while enrolled in science courses. Students are not
allowed to use school laboratories outside of regular science course classes unless they first
obtain permission and are directly supervised by the instructor during their work.
Section 3: GENERAL PRINCIPLES
The following statements and explanations are general principles for the use of those handling
laboratory chemicals. While the list is not complete, these concepts provide the fundamental
underpinning for laboratory work at this College.
3.1 Be Prepared
The College will train employees in how to find and use information from SDSs, this Chemical
Hygiene Plan, and other safety publications. Employees should familiarize themselves with the
hazards associated with the chemicals they expect to use and should take appropriate steps to
minimize their exposure to those chemicals.
3.2 Follow the Chemical Hygiene Plan
The Chemical Hygiene Plan provides specific laboratory practices designed to minimize
employees’ exposure to hazardous substances. Employees should follow the practices specified
in the Chemical Hygiene Plan to minimize their health and safety risks.
3.3 Minimize Exposure to Chemicals
It is prudent to minimize all chemical exposures, because most laboratory chemicals present
hazards of one type or another. Employees will follow general precautions for handling all
laboratory chemicals. Specific guidelines for some chemicals, such as those found in the
appropriate SDSs, will also be followed.
3.4 Consider the Risk
Employees should not underestimate risk, and exposure to hazardous substances should be
minimized. The decision to use a particular substance will be based on the best available
knowledge of each chemical’s particular hazard and the availability of proper handling facilities
and equipment. Substitutions, either of chemicals or experiments, will be made where
appropriate to reduce hazards without sacrificing instructional objectives. When the risk
outweighs the benefit and no substitute is available, then the experiment, procedure, or chemical
8
should be eliminated. The Chemical Hygiene Officer should be consulted before final
determinations and decisions are made in this regard.
3.5 Observe PELs and TLVs
The permissible exposure limit (PEL) and threshold limit value (TLV) of a typical chemical used
in the laboratory are available on the SDS for that chemical. Employee exposure to hazardous
chemicals should not exceed those limits.
3.6 Provide Adequate Ventilation
The best way to prevent exposure to airborne substances is to prevent their escape into the
laboratory by using hoods or other ventilation devices. Those devices should be kept in good
working condition in order to provide employees with a safe working area. The later section on
inspections in the laboratory (Section 7) establishes procedures for ensuring that equipment is
working properly.
3.7 Use Safety Data Sheets
The College should not accept a chemical from a supplier unless it is accompanied by the
corresponding SDS, or an SDS from that supplier for that chemical is already on file. All SDSs
should be accessible to employees at all times. Employees should be trained to read and use the
information found on SDSs.
Section 4: STANDARD OPERATING PROCEDURES
The goal of the Chemical Hygiene Plan is to protect employees who work in the laboratory,
others who may be exposed, and the environment from hazardous chemicals. This section is
written in several parts and is meant as a guide for the College and its employees. Other specific
safety rules for a particular laboratory may be added by the Chemical Hygiene Officer, as needed.
It is recommended that these same standards be communicated to students, expected of students,
and promoted by the school and laboratory personnel.
4.1 General Rules
The instructor (and technical support staff, if any) should review laboratory instructions, safety
procedures, and reagents prior to each laboratory activity. They should be aware of the
following:
The chemical hazards for each chemical, as determined from the SDS or other appropriate
reference.
Appropriate safeguards for using each chemical, including personal protective equipment.
Location and proper use of emergency equipment.
Proper storage of chemicals.
9
Appropriate personal hygiene practices.
Correct methods for transporting chemicals within the laboratory facility.
Appropriate procedures for emergencies, including evacuation routes, spill cleanup
procedures, and fire control.
Proper procedures for the disposal of hazardous substances.
Procedures for notifying supervisory persons in the case of an accident or injury.
4.2 Working Alone
Employees should not work alone (not visible/no line of site from any other person) in a
laboratory or chemical storage area unless other employees are in the vicinity (either in an
adjacent room or immediately across a hallway capable of hearing a call for help) and are aware
that someone is in the laboratory, in which case periodic checks should be made. At no time
should a student ever work alone in a laboratory or chemical storage area.
Whenever chemicals are in the laboratory and not in locked cabinets or storerooms, the
unattended laboratory will be locked.
4.3 Personal Protective Equipment and Clothing
The employee should use appropriate protective clothing and equipment. Laboratory aprons or
coats, eye protection, and nonpermeable gloves are considered standard equipment for school
laboratory programs and should be readily available to employees. Required personal protective
equipment must be supplied by the College.
4.3.1 Eye Protection
Everyone, including visitors to the laboratory, should wear eye protection at all times, when
working with chemicals.
Protective eyewear should provide splash and impact protection and should conform to ANSI
Standard Z87.1-1989. Prescription eyeglasses, even with side shields, are not acceptable
protection against impact and chemical splashes.
Equipment should be available with which to clean and sterilize goggles and/or safety glasses
and should be used whenever two or more persons use the same protective eyewear. It is
recommended that a sterilization cabinet be available, particularly for use with goggles shared by
students.
Contact lenses are not necessarily prohibited in the laboratory. If contact lenses are permitted,
chemical splash goggles must be worn at all times when chemicals are being used and there is a
potential for explosions, implosions, splashes, or whenever corrosive liquids are in use. Because
there may be a need to remove contacts quickly, contact lens wearers must inform the appropriate
personnel of the contacts before an emergency arises. Approved standing shields or face shields
10
should be used when there is potential for explosions, implosions, or splashes, or when corrosive
liquids are used, in addition to appropriate protective eyewear (i.e. goggles or safety glasses).
4.3.2 Protective Clothing
Protective clothing worn in the laboratory should offer protection from splashes and spills and
should be easy to remove in case of an accident and should be fire resistant. They should be long
enough to cover from the neck area to the knees. Clean chemical and fire resistant laboratory
coats may be worn. They should be long-sleeved and long enough to cover the knees. Snap
fasteners or Velcro closures are better than buttons, because the laboratory coat is more easily
removed in an emergency.
It is recommended that shorts, cutoffs, or short skirts not be allowed to be worn in the laboratory.
Shoes should have low heels with fully covered “uppers.” There should be no open toes or
uppers constructed of woven material. Jewelry such as rings or bracelets should not be worn in
order to prevent chemical seepage under the jewelry, contact with electric sources, catching on
equipment or damage to the jewelry itself.
Laboratory coats, jackets, aprons, or clothes on which chemicals have been spilled should be
washed separately or disposed of (possibly as a hazardous waste, depending on the contamination
source).
4.3.3 Gloves
When gloves are required, it should be remembered that no one kind of glove is suitable for all
situations. The SDS should be consulted for information regarding the proper type of gloves to
be used. For example, corrosion-resistant gloves should be worn when working with corrosive
liquids.
Gloves that resist permeation by chemicals that are allergenic, sensitizing, or toxic should be
worn when appropriate.
Gloves should be removed before leaving the laboratory or touching door knobs, telephones, or
laboratory notebooks.
Gloves should be checked before each use to ensure the absence of cracks and small holes and
should always be worn with the same side out.
4.4 Advance Planning
The employee should not rely solely on the textbook, laboratory manual, or other instructional
material for safety precautions required for a particular experiment. Consult the SDSs for
chemicals and safety references for equipment, particularly when the anticipated experiment is
new to the instructor. The instructor or laboratory technician should review potential hazards and
specifically describe them to all classes and all students immediately before each experiment.
11
The scale of the procedure should be reduced as much as possible to bring to a minimum the
generation of waste chemicals. Use only those chemicals for which the ventilation system is
adequate.
4.5. Personal Behavior
The laboratory should never be left unattended while students are performing an experiment in
that laboratory. However, it is recognized that some experimental procedures, such as
crystallization or incubation, are a normal part of some experiments and that such procedures
may safely be left while they are in progress. The employee should use the best available
information when deciding whether a particular procedure may be left unattended. Additionally,
activities using unauthorized chemicals should not be performed by employees or students.
Horseplay, pranks, or other acts of mischief should not be tolerated in chemical work areas and
laboratories.
Every precaution should be taken to insure that chemicals are never removed from the laboratory
by unauthorized persons.
4.6 Personal Hygiene
All employees should use appropriate personal hygiene practices, including the following:
Wash promptly whenever any hazardous chemical has contacted the skin, except in those few
cases in which chemicals will react dangerously with water.
Never pipet by mouth. Always use a bulb or other device for suction.
Avoid inhalation of chemicals used for an experiment, including gases, vapors, and aerosols.
“Wafting” to test chemical odors should only be done with extreme caution and only when
specifically directed to do so in the written experimental procedure.
Wash well with soap and water before leaving the laboratory, even if gloves have been worn.
Never wash with organic solvents.
Never smoke in the laboratory. Be aware that tobacco products in opened packages can
absorb chemical vapors.
Do not apply or store cosmetics in the chemical laboratory.
Seek immediate and appropriate medical treatment whenever signs or symptoms of exposure
to a hazardous chemical are manifested.
4.7 Housekeeping
Because many accidents may be attributed to sloppy work areas, all laboratory spaces must be
kept clean and contain only those items needed for the task at hand. Cleanup should immediately
follow the completion of each operation and at the end of each day.
Place all wastes in appropriate, segregated receptacles that are correctly labeled.
12
Store all equipment and chemicals properly. Chemicals should not be stored in aisles, on the
floor, in stairwells, on desks or laboratory tables.
Do not leave chemicals overnight on shelves over the workbench.
Never block access to emergency equipment, showers, eye washes, or exits.
Clearly label all chemical containers with the identity of the contents and the hazards those
contents present. These labels should be consistent with all state and federal requirements.
Keep all cabinets and drawers closed when not in use to avoid catching and bumping hazards.
Clean all working surfaces and floors on a regular basis. Keep the floor clear of slipping
hazards such as ice, spilled liquids, glass beads, or other small items.
Clean up all chemical spills as soon as they occur. Chemicals and cleanup materials should
be disposed of correctly.
4.8 Food Handling
No food or beverages should be stored, handled, prepared, or consumed in the laboratory or other
areas where chemicals are used or stored. Additionally, laboratory chemicals and laboratory
equipment should not be brought into designated “non-laboratoryor eating areas. Glassware or
utensils that have been used for laboratory operations should never be used to prepare or
consume food. Laboratory refrigerators, ice chests, microwave ovens, and cold rooms should not
be used for food storage or preparation.
4.9 Glassware
Careful storage and handling procedures should be used to avoid glassware breakage. In the
event of breakage, protection for the hands should be worn when picking up the broken pieces.
Small pieces should be swept up with a brush and pan. Broken glass should be separated from
other waste by placing it in a special container marked ‘Broken Glass’. Broken glass
contaminated with chemicals may need to be treated as hazardous waste depending on the type of
chemical – consult with the Environmental Health and Safety Officer for assistance.
When inserting glass tubing into rubber stoppers or corks or when placing rubber tubing on glass
hose connections, adequate hand protection in the form of heavy gloves or cloth towels should be
used. When inserting glass tubing into a stopper, the hands should be held close together to limit
movement of glass, and the glass should be lubricated. Tubing should be fire polished or
rounded at the end.
4.10 Flammability Hazards
Open flames should not be used to heat a flammable liquid or to carry out a distillation under
reduced pressure. Before lighting a flame, all flammable substances should be removed from the
immediate area of the flame. All containers of flammable substances in the area should be
checked to ensure that they are tightly closed.
Flammable materials should be stored in a flammable liquid storage cabinet or other appropriate
location. When transferring significant quantities of flammable liquids from one container to
13
another, it is particularly important that they be properly grounded to prevent accidental ignition
of flammable vapors and liquids from static electricity or other sources of ignition. Large
quantities of flammable chemicals stored outside cabinets should be in flame-proof storage cans
which conform to NFPA (National Fire Protection Association) guidelines. NFPA Standards 30,
Flammable and Combustible Liquids Code, and 45, Fire Protection for Laboratories Using
Chemicals, and/or the applicable local fire codes should be followed.
4.11 Electrical Hazards
All electrical outlets should have a grounding connection accommodating a three-prong plug.
Most electrical equipment is wired with a three-prong plug. The grounding post should never be
removed from such a plug. Some equipment is designed for safe use with two-prong plugs. If
the appliance comes with a two-prong plug, there is no need to change; it will work in a three-
prong socket.
Employees should contact the Physical Plant in the case of an emergency for considerations that
electrical service to the laboratory need to be cut, or if power goes out due to unforeseen
circumstances. Laboratory lighting should be on a separate circuit from electrical outlets with a
minimum of 90-minutes of illumination, so that electric service can be cut off during an
emergency, if need be, and particularly for exit routes. All electrical outlets should be checked
for continuity after initial occupancy (upon new construction or when first used by an employee)
and whenever electrical maintenance or changes occur.
If electrical equipment shows evidence of undue heating, it should be immediately unplugged.
4.12 Compressed Gases
If compressed gas cylinders are used in the laboratory, procedures for their use and storage
should be in accordance with guidelines established by:
National Fire Protection Association (NFPA) Standard 55, Standard for the Storage, Use,
and Handling of Compressed and Liquefied Gases in Portable Cylinders;
American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE)
recommended guidelines;
Compressed Gas Association (CGA) Standard P-1 2008; and,
OSHA Subpart H (specifically 1910.101 – 1910.105) regulations (provided as Appendix B).
Some of the more important considerations in using gas cylinders correctly are the following:
No cylinder should be moved from one location to another until the protective cap is securely
in place.
Both full and empty cylinders should only be stored where they may be securely restrained by
straps, chains, or a suitable stand.
All cylinders should be used with a correct regulator, and should be fitted with delivery tubes
that do not leak and which are tightly fastened to the cylinder.
14
A cylinder may be considered to be empty when there is still a slight positive pressure.
An empty cylinder should be returned to the supplier as soon as possible after having been
emptied, or when it is no longer needed.
Cylinders should not be exposed to temperatures above 50 °C (122 °F).
4.13 Prior Approval
Professors and technical staff may need to obtain prior approval from the Chemical Hygiene
Officer whenever a new laboratory experiment or test procedure is to be carried out for which the
potential for harm (conditions for which are identified below), either chemical, physical or
biological, is present. The potential for harm may be affected by a change in the amounts of
materials being used, the conditions under which the experiment is to be conducted, or the
substitution, deletion, or addition of a chemical.
Prior approval may be needed using the form provided as Appendix C and AFTER consultation
with the Chemical Hygiene Officer before doing any procedure where one or more of the
following conditions exist (generally under normal temperature and pressure):
Potential for a rapid rise in temperature.
Potential for a rapid increase in pressure.
Potential for chemical explosion.
Potential for spontaneous combustion.
Potential for the emission of toxic gases that could produce concentrations in the air that
exceed toxic limits.
Prior approval should also be obtained before again performing any procedure after there has
been a failure of any of the equipment needed for the process, especially of safeguards such as
fume hoods.
Section 5: RECORD-KEEPING PROCEDURES
The College should maintain specific records to verify safety practices.
5.1 Air Concentration Monitoring
The College requires that records of air concentration monitoring be maintained for at least 30
years and that they be accessible to employees and/or their representatives. Such monitoring
should be done as recommended by the Chemical Hygiene Officer and follow generally accepted
monitoring techniques.
Regular instrumental monitoring of airborne concentration is not usually justified or practical in
school laboratories. Monitoring may be appropriate when toxic materials are used or stored, or
when ventilation devices are tested or redesigned. It is required after each documented incident
of exposure to toxic chemicals.
15
5.2 Training Records
The College should maintain records of employee training for at least 30 years and should make
those records available to employees and/or their representatives when requested.
5.3 Safety Data Sheets
The College should maintain a file of manufacturers’ SDS’s and should make them accessible to
employees in the laboratory. If a SDS is not available when a new chemical is received, that
chemical should not be used until a SDS is obtained. It is recommended that copies of SDSs be
kept at both the Environmental Health and Safety Office and the Department where the chemical
is located. See Section 6.9 for more information.
5.4 Exposure Testing Records
Records of exposure assessments should be maintained for at least 30 years, and they should be
made available to employees and/or their representatives upon request. Exposure testing
procedures and results of that testing should be sent to the Chemical Hygiene Officer, who is
responsible for maintaining these records.
An accurate record of any measurements taken to monitor employee exposures should be kept,
transferred, and made accessible to each employee. Each employee should be notified of any
monitoring results within 15 working days after receipt of the results, either individually, in
writing, or by posting the results in an appropriate location that is accessible to employees.
5.5 Medical Records
The College requires the records of medical consultations, medical examination, and all reports
derived from such consultations and examinations be maintained for at least 30 years. These
records must be accessible to employees and/or their representatives upon request and are
subject to Federal and State privacy laws, statues and regulations, including but not limited
to the Health Information Portability and Accountability Act (HIPAA) and Family
Education Rights and Privacy Act (FERPA).
5.6 Prior Approval
Laboratory employees should be informed of those laboratory procedures and operations which
require prior approval from the Chemical Hygiene Officer (see Section 4.13), so that these
activities can be carefully monitored for adherence to the Chemical Hygiene Plan. Request for
approval must be made in writing, using the form provided in Appendix C.
5.7 Incident Reports
Each incidence of an accident of injury or “near miss” should be reported to the Chemical
Hygiene Officer (and to the Environmental Health and Safety Officer if he/she does not carry
16
both designations) in writing in accordance with Worker’s Compensation rules. If staff or
students were witnesses to the accident of injury, they should also complete the appropriate form
found in Appendix D (also available on the College’s website). The College should keep records
for 30 years from the time of the lost work, in the event of lost work resulting from an exposure
to a hazardous chemical or a job-related accident. Near miss reports are very useful in
determining what areas might benefit from a review of procedures.
5.8 Chemical Inventory Records
Each department should maintain a Chemical Inventory List, which should be updated at least
annually. Copies of the Chemical Inventory List should be kept in the Department and by the
Chemical Hygiene Officer. If this is done by a computer-based inventory program, backup
copies should be maintained in a separate location. See Section 6.7 for more information.
5.9 Waste Disposal Records
The College should maintain records of waste chemicals and products from reactions or
processes that are transferred to an authorized and/or certified chemical disposal agent, and
chemicals that are transported to a new site. These records should conform to requirements of
the Environmental Protection Agency and Department of Transportation, either of which may
have jurisdiction over these types of transfers. The records should also conform to State
requirements.
5.10 Safety Inspections and Recommendations
The College should keep records of regular safety inspections, including the date of the
inspection and the person conducting the inspection. The College should keep records of
permanent safety equipment, showing the dates of inspection and the results of any inspection.
Examples of equipment to be inspected are fire extinguishers, drench showers and eye wash
fountains. The College should maintain records showing dates of needed repairs and regular
maintenance for control systems.
Written safety suggestions from employees should be recorded by the College. The dates the
suggestions were submitted, the name of the person submitting the suggestion, the disposition of
the suggestion, and the reasons for that particular action should be kept.
Section 6: LABORATORY SAFETY PROCEDURES
6.1 Employee Exposure Protection and Monitoring
If there is reason to believe that exposure levels for a regulated substance have exceeded the
action level or permissible exposure limit, the College’s Chemical Hygiene Officer should ensure
that employee or student exposure to that substance is measured.
17
Factors which may raise the possibility of overexposure and therefore warrant an initial
measurement of employee or student exposure include:
The manner in which the chemical procedures or operations involving the particular
substance are conducted.
The existence of historical monitoring data which shows elevated exposures to the particular
substance for similar operations.
The use of a procedure which involves significant quantities or is performed over an
extended period of time.
There is reason to believe that an exposure limit may be exceeded.
Signs or symptoms of exposure (e.g., skin or eye irritation, shortness of breath, nausea, or
headache), which are experienced by employees or students. (Some of these symptoms are
very general and can be due to many other causes including emotional stress or hysteria.)
If the initial exposure determination described above indicates employee or student exposure
over the action level for a particular substance, the College should immediately comply with the
exposure-monitoring requirements for that substance.
6.2 Laboratory Facilities
The type and scale of work conducted in a laboratory should be appropriate to the physical
facilities available and to the quality of the ventilation system. A laboratory should include,
where appropriate:
An adequate general ventilation system with air intakes and exhausts located so as to avoid
intake of contaminated air.
Well-ventilated stockrooms and storerooms.
Proper chemical storage for specific hazardous materials such as flammables, corrosives,
carcinogens, and highly toxic chemicals, so far as they are likely used.
Adequate laboratory hoods and sinks.
Emergency equipment, including proper fire extinguishers, spill kits, alarms, access to a
telephone with an outside line, eye wash, safety shower, and fire blanket.
First aid equipment including first aid kits.
Arrangement for proper waste storage and disposal.
6.3 Laboratory Ventilation
Laboratory fume hoods are not meant for either storage or disposal of chemicals. If a hood must
be used for storage, in order to provide adequate ventilation for flammable chemicals, for
example, it must not be used for laboratory experiments or transfer of chemicals unless safe use
for chemicals within can be demonstrated. In the event it cannot be demonstrated that safe use
can also be achieved, it must be used only for storage.
General laboratory ventilation should not be relied on for protection from exposure to hazardous
chemicals. A rate of 8–12 room air changes per hour should be the accepted standard when local
18
exhaust systems such as hoods are used as the primary method of control. Laboratory airflow
should not be turbulent and should flow continuously throughout the laboratory.
The quality and quantity of ventilation should be evaluated when installed, regularly monitored,
and reevaluated whenever a change in ventilation devices is made, or the ventilation system is
repaired.
6.4 Medical Consultations and Medical Examinations
Employees who work with hazardous chemicals should be provided with an opportunity to
receive medical attention when overexposure to a hazardous chemical is reasonably suspected.
In the event that employees’ work involves regular and frequent handling of toxicologically
significant quantities of a chemical, the Chemical Hygiene Officer should determine whether
consultation with a qualified physician is necessary to set up a plan for routine surveillance.
Cause for Consultation or Examination
In relation to the exposure of hazardous chemicals, medical attention should be provided to an
employee under the following circumstances:
Whenever an employee develops signs or symptoms of exposure to a hazardous chemical to
which the employee may have been exposed in the laboratory.
Whenever exposure monitoring reveals an exposure level above the action level or
permissible exposure level for an OSHA-regulated substance.
Whenever an event such as a spill, leak, or explosion, takes place in a laboratory which
results in the likelihood of exposure to a hazardous substance.
Type of Medical Attention
All medical examinations and consultations should be performed under the direct supervision of
a licensed physician and in full accordance with 29 CFR 1910.1450(g).
Information for the Physician
The following information should be provided to the physician conducting medical consultations
and examinations:
The identity of hazardous chemicals to which the employee may have been exposed.
A copy of the safety data sheet for the chemical.
A description of the conditions under which the exposure occurred, including quantitative
exposure data.
A description of the signs and symptoms of exposure that the employee is experiencing.
19
Physician’s Report
A written opinion from the examining physician specializing in occupational medicine
for any consultations or examinations performed under this standard should include any
recommendation for further medical attention, the results of the medical examination and any
associated tests, any medical condition revealed during the examination which might
compromise employee safety during, or as a result of, exposure to hazardous chemicals found in
the workplace, and a statement that the employee has been informed by the physician of the
results of the consultation or examination and any medical condition that may require further
examination or treatment. The written opinion should not reveal specific diagnoses unrelated to
occupational exposure, except as noted above.
6.5 Chemical Purchase and Procurement
The purchaser of chemicals should be guided by the maxim that less is better. The lower the
chemical inventory, the fewer the problems associated with storage, and the less likely that the
College will face excessive costs to dispose of outdated or surplus chemicals.
Chemicals should be ordered in quantities that are likely to be consumed in one year or less.
Chemicals should be purchased only when needed for specific experiments or research
projects. The chemicals should be purchased only in the quantity sufficient for the declared
use.
All chemicals should be in tightly closed, sturdy, and appropriate containers.
A chemical should not be accepted without being accompanied by the safety data sheet.
The container should be marked with the date at the time it is received and the date it is
opened.
Chemicals should not be accepted if the original container has been broken, opened, or has
been compromised in some other way.
The Chemical Inventory List should be updated each time a new chemical is received.
Donated chemicals should be accepted only after approval is obtained from the Chemical
Hygiene Officer. It should be established that the donated chemical is in excellent condition,
that an appropriate safety data sheet is available, and that there is a specific use for the
donated material.
6.6 Storage and Distribution
All chemicals should be in tightly closed, sturdy, and appropriate containers.
If the chemical has been transferred to a secondary container, the new container should be
appropriately labeled, including all of the hazard information. Specifications for labeling
follow in Section 6.8.
Chemicals should be stored based on the reactive nature of the chemical. Storage patterns
should never be based solely on the alphabetical arrangement of chemicals.
The classification system used for the storage of chemicals should be displayed in the
principal storage area.
20
Large containers and containers with reactive chemicals, such as acids and bases, should be
on low shelves. No chemical should be stored on top of a storage shelf or cabinet.
All shelves on which chemicals are stored should have a lip of approximately 3/4" or greater
in order to prevent bottles from sliding off the shelf.
Flammable chemicals should be stored in approved storage cans or approved flammable
chemical storage cabinets.
Combustible packaging material should not be stored near flammable chemical storage
cabinets.
All storage areas should be securely locked when not in use by the employee. Storage and
preparation areas should be accessible only to those persons authorized to use the chemicals.
Such personnel should have had proper training in the handling and use of the chemicals.
Chemicals classified as acute poisons should be kept in a separate, locked location, which has
been appropriately labeled.
Chemicals which present a fire hazard should be stored in quantities less than 500 mL, unless
metal safety cans are used, or the container is stored in a suitable flammable storage cabinet.
If approved metal safety cans are used, the spring-loaded closure should not be disabled, the
flame-arrestor screen should be kept in place, the arrestor screen should be replaced
whenever it is punctured or damaged, and the arrestor should never be immersed in the
flammable liquid.
Chemicals should not be distributed to other persons or to other areas of the College without
prior approval of the Chemical Hygiene Officer. Chemicals should not be transferred to
another location without the simultaneous transfer of a copy of the appropriate safety data
sheet, nor should they be transferred without the person receiving the chemicals having had
appropriate training in their use, storage, and disposal.
6.7 Inventory Control
Various regulatory agencies require the College to maintain a complete, accurate and up-to-date
inventory of its toxic and hazardous materials. Primarily though, inventories are essential to
inform individuals which chemicals they may have the potential to be exposed to, further
allowing them to better understand the associated hazards and risks of these chemicals.
Each department head or designee is responsible for ensuring that a chemical inventory list of the
hazardous chemicals and toxic substances used, stored or otherwise kept in each laboratory or
work area under his/her purview is created and maintained.
A good way to prepare a comprehensive inventory list is to survey your work area(s) to do a
physical assessment, and purchasing records also may help. The broadest possible perspective
should be taken when doing the survey. Considering all substances to be potentially toxic and
hazardous simplifies the approach even though it may unnecessarily include a few materials that
are essentially non-hazardous.
21
Items NOT REQUIRED to be Inventoried:
Even though some items may not be entered into the inventory, the user is still responsible to
obtain a current Safety Data Sheet (SDS) for the product. The list below provides some examples
of common materials that do not need to be inventoried.
Any secondary chemical container that is produced in the lab from a primary chemical
container(s) that is already inventoried, for example:
o 1N Sodium Hydroxide (NaOH) that is made from a commercially available 10N
NaOH solution or solid NaOH
o Squirt bottles and spray bottle
o Conical and “Falcon” tubes with chemicals or samples in them
Biological material, for example:
o Plant or animal tissue, blood or blood products
o Reproducing biological organisms, bacteria, viruses, fungi or yeast
o Enzymes, antibodies, proteins, peptides, nucleic acids
o Conjugated antibodies and proteins
Tissue culture media or other growth media
Buffer solutions for pH probes
Non-chemical diagnostic materials that contain a film on any surface (e.g. 96-well plate)
Chemical spill kits
Inventories must be completed in a Microsoft Excel template available from the Environmental
Health and Safety Officer, or one can be downloaded through links included in the Chemical
Inventory Management section of FSC’s Environmental Health and Safety website. The
Chemical Inventory List should contain the following information about each chemical found in
storage: Product Name; Synonyms or Other Names (If known/available); Manufacturer, Catalog
(Cat.) No., Chemical Abstracts Service (CAS) No., and/or Other Identifying Information;
Physical State (Solid, Liquid or Gas); Number of Containers of same type/size; Quantity
(volume/weight); and the Unit of Measure (lbs, Kg, mg, etc.).
Once a chemical inventory has been completed, the electronic file MUST be emailed to the
Environmental Health and Safety Officer at ehs@farmingdale.edu.
Each chemical inventory list must be updated at least annually, or whenever there is a substantial
change (i.e. a chemical is added or removed). After each annual update, and whenever there is a
change made, a revised chemical inventory MUST be emailed to the Environmental Health and
22
Safety Officer at ehs@farmingdale.edu and, where possible, the revised section or reason for
change be highlighted, marked up, explained, etc. for ease of rectification.
Upon receipt by the Environmental Health and Safety Officer, the chemicals included on the
spreadsheet will be added to the College's Chemical Inventory and Management System,
MSDSonline, where all chemicals inventoried on Campus are listed. In addition, MSDSonline
also provides access to associated Safety Data Sheets, identifies where these chemicals are stored
and communicates pertinent health and safety information (among other features) aimed at better
communicating the hazards and risks associated with the chemicals used and stored on Campus.
6.8 Hazard Identification and Labels
Laboratory chemicals should be properly labeled to identify any hazards associated with them
for the employees’ information and protection.
If a chemical is stored in its original bottle, it should have the manufacturer’s original label
identifying potential hazards, and the date of purchase, the date opened, and the initials of the
person who opened the container.
If a chemical has been transferred to a secondary container, the new container should be
appropriately labeled with the chemical name, formula, concentration (if in solution), solvent
(if in solution), hazard warnings, and name or initials of the person responsible for the
transfer.
Unlabeled bottles should not be opened, and such materials should be disposed of promptly,
as outlined in the section on disposal procedures.
6.9 Safety Data Sheets
The Hazard Communication Standard requires chemical manufacturers and importers to evaluate
the hazards of the chemicals they produce or import. Using that information, they must then
prepare more detailed technical bulletins called Safety Data Sheets, or SDSs.
The SDSs for each chemical used in the laboratory should give recommended limits or OSHA-
mandated limits, or both, as guidelines to exposure limits. Typical limits are expressed as
threshold limit values (TLVs), permissible exposure limits (PELs), or action levels. When such
limits are stated, that limit, along with any other information about the hazardous characteristics
of the chemical, should be used to set laboratory guidelines. These laboratory guidelines may be
used by the Chemical Hygiene Officer and the department technical staff in determining the
safety precautions, control measures, and personal protective equipment that apply when working
with that toxic chemical.
Each department head or designee is responsible for maintaining a manufacturer-specific SDS for
each hazardous or toxic substance used or stored in his/her work area(s), and for ensuring that
they are readily accessible during each work shift to employees when they are in their work
area(s).
In lieu of maintaining hard copies of SDS’s (i.e. binder, folder, cabinet, etc.), electronic versions
will be available through MSDSonline, Farmingdale State College's Chemical Inventory and
Safety Data Sheet service provider.
23
Please note, MSDSonline may ONLY be used as the SOLE SDS resource if ALL employees
with the potential for chemical exposure in any given area have full access (i.e. computer
access, a general understanding of how to navigate the system, etc.) to the service;
otherwise, hard copies must be made readily available as well.
Each department head or designee must also send copies of all SDSs for new chemicals as they
arrive to the Environmental Health and Safety Officer. This can be done one of two ways:
1. Access the MSDSonline site through links included in the Safety Data Sheet (SDS)
Management section of FSC’s Environmental Health and Safety website and enter the product
name you're seeking to submit an SDS for in the search engine (you can narrow down your
search by also including such information as the CAT. Number, the CAS Number, the
Manufacturer, etc.) - if your initial search is not successful, try adding or removing information
you've included in the search field and resubmit.
Once you've found the correct SDS, check the box associated with that product (left of product
name) which prompts you to select "Assign to Company List"; click on that prompt, which opens
up a second screen.
Fill out all required information on this "Approval Details" page and hit 'submit'. Your
submission will be sent to a queue for the System Administrator's approval (the EH&S Officer).
Please note: if your specific location is not listed in the drop down menu on the "Approval
Details" page, call or email the EH&S Officer so that it can be added.
2. SDSs may be emailed to the EH&S Officer at ehs@farmingdale.edu, or, the SDS(s) can be
faxed to the attention of the Environmental Health and Safety Officer at (631) 420-9173.
Whichever means is used to submit the SDS, be certain to add under separate cover details that
include the specific location where the chemical(s) are to be used/stored - identify the Building,
Department, Room Number and the Specific Location (i.e. cabinet A, stockroom, under fume
hood #1, etc.). Once received, the proper SDS will be “paired” with the associated chemical(s)
within MSDSonline, and hard copies will be maintained on file.
SDSs should be reviewed prior to purchase to properly evaluate the hazards and risks
associated with the substances being considered for use. As part of the college’s ongoing
Hazard Communication Training Program, all laboratory employees will be trained to
read and understand the SDSs.
Each department head or designee is responsible for ensuring that an appropriate SDS is
forwarded with each initial product shipment. SDSs are also requested for purchases made
through the Research Foundation. If the SDS is not received with the initial shipment, it is the
responsibility of the ordering entity (department head/designee) to contact the supplier
(manufacturer/importer/distributor) and acquire an SDS, put a copy in the department’s SDS
binder, file, or appropriate area, and/or send a copy of the SDS to the Environmental Health and
Safety Officer as explained above.
In addition, each department head or designee is responsible for ensuring that SDSs that have
been replaced with a newer version and/or SDSs of discontinued materials are retained in
accordance with the General Retention and Disposition Schedule for NYS Government Records,
24
and other applicable laws and regulations. As a general rule, SDSs are retained for at least 40
years after superseded or obsolete.
Alternatively, if SDSs are/have been forwarded to the Office of Environmental Health and
Safety, they will be maintained there for the required time period, and/or, will be “banked” in the
MSDSonline service database, which will be backlogged/archived/saved at least annually.
6.10 Waste Disposal
The College’s Chemical Hygiene Officer should ensure that laboratory chemicals are disposed in
compliance with appropriate regulations and in a manner which minimizes damage to human
health and the environment.
Every process that uses chemicals has the potential for producing hazardous waste. The
purchaser or producer of chemicals should take into consideration the waste that should be
produced and the cost of waste disposal. The product of a reaction or process only becomes
hazardous waste when it is removed from the reaction system, deemed to be a “waste” and is a
hazardous material (meets the definition of “hazardous waste”). Disposal of hazardous waste
must be done by a licensed contractor through a permitted facility.
The following are specific guidelines for hazardous waste disposal:
Chemicals should be ordered in quantities that are likely to be consumed in one year or less.
Potential waste materials are surplus, old, and/or unnecessary chemicals. Every attempt must
be made to avoid accumulating such chemicals.
No flammable, combustible, or water-immiscible material will be poured down the drain
unless specifically allowed for by law and with prior approval by the Chemical Hygiene
Officer.
Separate waste containers should be provided for heavy metal compounds, chlorinated
hydrocarbons, and nonchlorinated hydrocarbons. Separation of wastes in this manner will
make disposal less costly.
Acids and bases may be neutralized before disposal down the drain only with prior training
and approval by the Chemical hygiene Officer.
Hazardous waste should never be placed in the common solid trash container(s).
Waste chemicals should be stored in appropriately labeled containers, inside secondary
containment.
The products of projects, experiments, or other chemical procedures should be recycled
and/or decontaminated whenever possible.
All waste containers should have an up-to-date log of the material that is in the container.
Each entry for an addition to the container should be dated and initialed by the instructor, or
person who puts the waste in the container. The entry should provide the correct chemical
name and amount of chemical added.
When feasible and safe, a large container of a given waste should be used instead of several
small containers of the same material for financial reasons.
25
Waste materials should not be allowed to accumulate in laboratories or preparation rooms.
The sealed containers should be removed to the designated waste storage location. There are
regulatory limits depending on quantity which need to be verified with local officials.
Waste materials should be identified using a chemical identification form and/or label
ensuring sufficient information for their safe transportation, treatment, storage, and disposal.
The disposal of hazardous wastes should follow the guidelines established by the appropriate
local, State, and federal regulations.
Section 7: PROCEDURES FOR INSPECTIONS
All employees should be alert to unsafe conditions and should inform the Department Chair and
the Chemical Hygiene Officer in writing, when an unsafe condition occurs.
7.1 Laboratory Equipment
The presence of necessary safety equipment, in proper working condition (a reference list of
which is provided in Appendix E), should be maintained in each department and laboratory area
and assessed at least biannually. Safety equipment should be replenished/replaced as soon as
feasible if found to be missing, used or obsolete. The following general standards will apply:
Each hood will have a face velocity of 60–100 linear feet per minute.
Each shower will be capable of supplying a continuous flow of tepid, potable water. (ANSI
Standard Z358.1-1990)
Every eye wash will be capable of supplying a continuous gentle flow of aerated, tepid,
potable water to both eyes. (ANSI Standard Z358.1-1990)
Each fire extinguisher will be fully charged.
Every goggle sanitizer will have its UV bulb and timer operating properly.
Equipment will be tagged following the inspection, showing the date, inspector, and results.
7.2 Safety Inspections
Inspections in the laboratory shall be conducted at least annually. Inspection records will be kept
by the Department Chair and Chemical Hygiene Officer. A form for conducting these
inspections is shown in Appendix F. Laboratory inspections will be coordinated by the Chemical
Hygiene Officer.
Written (or digital) records of all inspections will be maintained by the Chemical Hygiene
Officer.
Section 8: SPECIFIC EXPOSURE CONTROL MEASURES
This section addresses criteria that would invoke the use of specific exposure control measures,
which are more stringent than those procedures specified as standard operating procedures or
general laboratory safety rules. These specific exposure control measures are designed to reduce
the exposure of instructors, aides, students, and other employees to especially hazardous
26
chemicals. Employees should read and understand these practices before commencing a
procedure using one or more of these chemicals.
8.1 Toxic Chemicals
The SDSs and labels for many of the chemicals used in the laboratory recommend specific limits
for exposure. Other limitations may be specified by OSHA-mandated limits. Typical limits are
threshold limit values (TLVs), permissible exposure limits (PELs), and action levels. When such
limits are stated, they should be used to assist the Chemical Hygiene Officer and the technical
staff in determining the safety precautions, control measures, and safety apparel.
When a TLV or PEL value is less than 50 ppm or 100 mg/m3, the user should use it in an
operating fume hood, glove box, vacuum line, or other device equipped with appropriate traps. If
none are available, no work should be performed using that chemical.
If a TLV, PEL, or comparable value is not available, the animal or human median inhalation
lethal concentration information, LC50, should be used as a guideline. If that value is less than
200 ppm or 2000 mg/m3 when administered continuously for one hour or less, then the chemical
should be used in an operating fume hood, glove box, vacuum line, or similar device, equipped
with appropriate traps. In none are available, no work should be performed using that chemical.
Whenever laboratory handling of toxic substances with moderate or greater vapor pressures is
likely to exceed air concentration limits, work with such liquids and solids should be conducted
in a fume hood, glove box, vacuum line, or similar device, equipped with appropriate traps. If
none are available, no work should be performed using that chemical.
Examples of toxic chemicals that were commonly used in the past are benzene, chloroform,
formaldehyde, bromine, carbon disulfide, carbon tetrachloride, cyanide salts, and hydrofluoric
acid. The use of these chemicals has been substantially reduced in the past few years because of
their toxicity.
8.2 Flammable Chemicals
In general, the flammability of a chemical is determined by its flash point, the lowest temperature
at which an ignition source can cause the chemical to ignite momentarily under certain controlled
conditions.
Chemicals with a flash point below 200°F (93.3°C) should be considered “fire-hazard
chemicals.” Any chemical whose SDS or label states “Flammable” is in this category.
OSHA standards and the National Fire Protection Association (NFPA) guidelines or local fire
regulations should be consulted on the proper use of flammable chemicals in the laboratory.
Specific references are found in Appendix G.
Fire-hazard chemicals in excess of 500 mL should be stored in a flammable solvent storage area,
safety cans, or in storage cabinets designed for flammable materials.
27
Examples of commonly used flammable chemicals are diethyl ether, acetone, methanol, ethanol,
glacial acetic acid, heptane, and petroleum ether (ligroin).
8.3 Reactive Chemicals
Reactivity information may be given in manufacturers’ SDSs and on labels. The most complete
and reliable reference on chemical reactivity is the current edition of Bretherick’s Handbook of
Reactive Chemical Hazards, edited by P.G. Urben, published by Butterworths. Other useful
references are cited in Appendix G.
A potentially reactive chemical is one that:
Is described as such on the label, in the SDS, or by Bretherick.
Is ranked by the NFPA as 3 or 4 for reactivity.
Is identified by the Department of Transportation (DOT) as an oxidizer, an organic peroxide,
or an explosive (Class A, B, or C).
Fits the Environmental Protection Agency (EPA) definition of reactive in 40 CFR 261.23.
Is known or found to be reactive with other substances.
Reactive chemicals should be handled with all proper safety precautions, including segregation in
storage and prohibition of mixing even small quantities with other chemicals without prior
approval and appropriate personal protection and precautions.
Examples of commonly encountered reactive chemicals are ammonium dichromate, nitric acid,
perchloric acid, hydrogen peroxide, and potassium chlorate.
8.4 Corrosive Chemicals and Contact-Hazard Chemicals
Corrosivity, allergen, and sensitizer information is provided in manufacturers’ SDSs and on
labels. Other guidelines on which chemicals are determined to be corrosive can be found in the
publications cited in Appendix G.
A corrosive chemical is one that:
Fits the OSHA definition of corrosive in 29 CFR 1910.1450 or 29 CFR 1910.1200.
Fits the EPA definition of corrosive in 40 CFR 262.22 (has a pH greater than or equal to 12,
or less than or equal to 2.5).
Is known to be reactive to living tissue, causing visible destruction of, or irreversible
alterations of, tissue at the site of contact.
A contact-hazard chemical is an allergen or sensitizer that:
Is so identified or described in the SDS or on the label.
Is so identified or described in medical or industrial hygiene literature.
Is known to be an allergen or sensitizer.
28
Corrosive and contact-hazard chemicals will be handled with all proper safety precautions,
including wearing safety goggles, gloves tested for the absence of pinholes and known to be
resistant to permeation or penetration by the chemical, and a laboratory apron or laboratory coat.
Examples of corrosive chemicals are hydrochloric, sulfuric, nitric, phosphoric, and perchloric
acids (all acids in greater than 1 Molar concentration), and potassium hydroxide (either solid or
in aqueous solution of greater than 1 Molar concentration).
8.5 Reproductive Toxins
A reproductive toxin is a compound that:
Is described as such in the applicable SDS or label, or;
There is statistically evidence based on at least one study conducted in accordance with
established scientific principles that acute or chronic reproductive health effects may occur in
exposed employees.
If such chemicals are used, they should be handled only in a hood and when satisfactory
performance of the hood has been confirmed. Skin contact should be avoided by using gloves
and wearing protective apparel. Persons using such substances should always wash hands and
arms immediately after working with these materials. Unbreakable containers of these
substances should be stored in a well-ventilated area and will be labeled properly.
Examples of reproductive toxins are organomercurial compounds and ethidium bromide, a
reagent used with DNA analysis.
8.6 Select Carcinogens
All work with these substances should be conducted in a Designated Area, such as a fume hood,
glove box, or portion of a laboratory designated for use of chronically toxic substances. Such a
Designated Area should be clearly marked with warning and restricted access signs.
Any procedure that may result in a generation of aerosols or vapors should be performed in a
hood whose performance is known to be satisfactory.
Skin contact should be avoided by using gloves and other protective apparel as appropriate. Any
protective clothing should be removed before leaving the Designated Area and placed in a
labeled container. Hands, arms, face, and neck should be washed after working with these
materials.
Select carcinogens should be stored in unbreakable containers in a ventilated area with controlled
access. All containers should be labeled with the identity and hazard of the substance.
Immediately upon completion of the project, all unused reproductive toxin should be disposed of
following standard hazardous waste disposal procedures.
29
Examples of select carcinogens are benzene, nickel metal dust, and vinyl chloride.
8.7 Exposure Potential
The routes of exposure to chemicals are inhalation, ingestion, contact with skin or eyes, or
injection.
Inhalation of chemical vapors, aerosols, gases, or dusts can produce poisoning through the
mucous membranes of the nose, mouth, throat and lungs. The degree of injury resulting from
exposure to these chemicals depends on the toxicity of the material, its solubility in tissue fluids,
its concentration, and the duration of exposure.
Ingestion is extremely dangerous. The relative acute toxicity can be evaluated by comparing the
LD50, which is defined as the quantity of chemical that will cause the death of 50% of the test
animals when ingested. Many chemicals will directly damage the tissue of the mouth, throat,
nose, lungs, and gastrointestinal tract.
Contact with skin and eyes can lead to local irritation as well as significant chemical injury. In
addition, many chemicals can be absorbed through the skin and may cause systemic poisoning.
Alkaline materials, phenols, and strong acids can cause permanent loss of vision upon contact
with the eye.
Injection of chemicals can occur through mechanical injection from glass or other materials
contaminated with chemicals.
Section 9: TRAINING OPPORTUNITIES
The College should provide training opportunities for all employees. These training
opportunities should include the transfer of information about the hazards of chemicals present in
the laboratory and about sources of information. In particular, the training program should cover
information found in the Laboratory Standard, manufacturers’ safety data sheets, this Chemical
Hygiene Plan, and the responsibilities of the employee.
Employees should be trained on the potential chemical hazards in the employees’ work areas and
on appropriate sections of the Chemical Hygiene Plan. This training should be provided to all
employees who actually work in the laboratory as well as to other employees whose assignments
may require that they enter a laboratory where exposure to hazardous chemicals might occur.
Employees who are responsible for receiving and handling shipments of new chemicals or
chemical wastes should also be informed of the potential hazards and appropriate protective
measures for chemicals they may receive.
Employees should receive information and training at the time of their initial assignment to a
laboratory and before assignments involving new exposure situations. Opportunities to refresh
their working knowledge should be provided at least once a year. As indicated earlier, the
training of laboratory personnel should be documented and made a part of the permanent record.
30
9.1 Information Program
Laboratory employees should be informed of at least the following information:
The contents of appropriate governing standards, as shown in Appendix A.
The location and availability of the Chemical Hygiene Plan.
The location and availability of known reference materials on the hazards, safe handling,
storage, and disposal of hazardous chemicals found in the laboratory.
The use and location of safety data sheets.
9.2 Employee Training Program
Laboratory employees should be trained on the applicable details of the Chemical Hygiene Plan,
including a review of the general rules for laboratory safety. The training program should
describe appropriate sections of the standard operating procedures, particularly those procedures
that require prior approval of the Chemical Hygiene Officer. Employees should be informed as
to the responsibilities of the Chemical Hygiene Officer responsible for the laboratory in which
they work. Emergency procedures adopted by the College, including response to spills, fires,
explosion, evacuation, and decontamination, should be described. Employees should be trained
in measures they may take to protect themselves from exposure to hazardous chemicals,
including the location and proper use of protective apparel and emergency equipment. In
addition, the training must also include a discussion of inventory procedures to be followed,
proper storage and ordering rules, and hazardous waste disposal procedures. A ‘Record of
Training’ form is provided as Appendix H.
9.3 Training of Students
The College requires that instruction in laboratory safety practices be provided to all students
involved in laboratory studies before experiments take place. Such training must be
appropriate to their level of chemical handling and potential exposure to hazardous chemicals.
The extent of training should be based on their grade level, courses of study, the laboratory
facility, and the individual policies of the College as stated in the Chemical Hygiene Plan. The
education of students is particularly important, because they are near the beginning of their
experience with science, chemicals, and chemical safety. Instruction in safety should include the
importance of the label and the SDS as important reference sources. As appropriate, the student
should also be introduced to other sources of chemical safety information.
Section 10: EMERGENCY PREVENTION AND RESPONSE
10.1 Standard Emergency Procedures
Emergency procedures should address a failure in the ventilation systems, evacuation, fire and
spill response, or the failure of other procedures to limit exposure of employees to hazardous
chemicals. These emergency procedures should be established, regularly practiced, and should
be posted in appropriate public places. These procedures should include the routes of egress
31
from the laboratory, procedures by which to notify appropriate individuals, and telephone
numbers of fire, police, ambulance, and College authorities.
The laboratory should have a plan for everyone to follow if an evacuation is necessary. The
employees should be sure that they know the main and alternative routes, as well as the
procedure for accounting for each person after an evacuation. The most appropriate response to a
serious fire is evacuation and subsequent action by the fire department.
10.2 Specific Emergency Response Procedures
When helping another person, employees should evaluate the potential danger to themselves
before taking action. Do not move any injured persons unless they are in immediate danger from
chemical exposure or fire.
Report the nature and location of the emergency to University Police by dialing (631) 420-2111.
The employee should follow the facilitys emergency response procedures. These procedures
have been established, documented, and practiced.
Other important emergency response contacts, particularly when campus facilities and/or
equipment are involved, a fire is evident or suspected, or if there is a threat of release of a
hazardous substance to the environment:
FSC Physical Plant (7 a.m. – 4 p.m.): (631) 420-2017
FSC Heating Plant (after 4 p.m.): (631) 420-2605
FSC Fire Marshall: (631) 420-2603
East Farmingdale Fire Department: (631) 249-0047
10.3 First Aid
Suitable first aid equipment should be available in the laboratory area, including a blanket, a
general first aid kit, and small bandages for minor cuts and abrasions. The College should have
personnel trained in first aid available during working hours to render assistance until medical
help can be obtained. Personal injury beyond the purely superficial requires professional medical
treatment. Additional information may be obtained from the Red Cross or references in
Appendix G.
10.4 Emergency Equipment
Each Department and the Chemical Hygiene Officer should ensure that adequate emergency
equipment is available in the laboratory and inspected periodically to ensure that it is functioning
properly. All personnel should be properly trained in the use of each item. It is recommended
that students also be trained to use the fire blanket, eye wash fountain, safety drench shower, and
telephone for safety purposes.
Equipment items that should be available in the laboratory include:
32
Eye wash fountain.
Fire extinguisher of an appropriate type.
Safety drench shower.
Telephone, with access to an outside line, for emergency response.
Fire blanket.
Identification signs.
10.5 Fire Prevention
The best way to fight a fire is to prevent it. Fires can be prevented or their severity considerably
reduced by proper housekeeping and by thoughtful reflection about what is being done. This
includes the prompt removal of waste, separation of flammable liquids from combustible
material, storage of only limited quantities of flammable material, and the maintenance of
unobstructed aisles and exits.
10.6 Dealing with a Fire
In preparation for dealing with a fire, a copy of the current Chemical Inventory List should be
available outside the work area. Laboratories should be posted with the National Fire Protection
Association (NFPA) diamond, which provides much emergency information. The information
on the NFPA warning must be current. Since fires involving laboratory chemicals increase the
possibility of explosions, special care should be taken to keep fire or excessive heat from volatile
solvents, compressed gas cylinders, reactive metals, and explosive compounds.
If a fire occurs, the following actions should be followed, depending on its severity:
A fire contained in a small vessel should be suffocated by covering the vessel. The vessel
should not be picked up, nor covered with dry towels or cloths.
Nearby flammable materials should be removed to avoid spread of the fire.
If a fire burns over a larger area, all persons should evacuate the area, except those trained
and equipped to fight structural fires.
The fire extinguisher should be used only by trained people, and only from a position from
which escape is possible.
Stairs, not elevators, should be used to leave the area of the fire.
The fire alarm should be activated and the fire department called.
Firefighters should be informed of what chemicals are involved.
As soon as possible, all extinguishers that were used should be recharged or replaced with full
extinguishers.
The facility’s fire protection plan should be documented and posted.
LOCAL PRACTICE MUST BE IN COMPLIANCE WITH LOCAL FIRE CODES.
33
10.7 Personal Injuries Involving Fires
Persons whose clothing is ablaze should STOP–DROPandROLL. If a safety shower is
immediately available, the individual may be doused with water. Once the fire is out, the
individual should be wrapped to avoid shock and exposure. The individual should be kept warm,
and medical attention should be promptly sought.
If a fire blanket is available, it should be used to smother the fire. The person should not be
wrapped to avoid the chimney effect with the fire blanket.
10.8 Chemical Spills on Personnel
For spills covering small amounts of skin, the area should be washed immediately with flowing
water for 15 minutes. To facilitate cleaning, jewelry should be removed. If there is no visible
burn, the 15-minute wash with water is sufficient. If a burn is visible, medical attention should
be sought after the washing has been completed. After washing, the SDS should be consulted to
determine if any delayed effects should be expected. Depending on the information from the
SDS, follow-up medical attention may be necessary.
For larger spills, the same procedures should apply, except that it may be appropriate to use the
safety drench shower to assure thorough and complete washing.
For spills on clothing and whenever necessary, the clothes as well as shoes and jewelry to
facilitate washing should be removed as quickly as possible. The safety drench shower should be
used for 15 minutes and any affected skin should be thoroughly flooded for 15 minutes. The
washing should be resumed if pain continues. No creams, salves, or lotions should be placed on
the affected area, and medical attention should be sought as soon as possible.
Special care should be taken to prevent chemicals from entering the eyes. Contaminated clothes
should be washed separately from other personal clothing, or disposed of as a hazardous waste
(depending on the contamination source).
10.9 Splashes in the Eyes
Whenever potentially harmful chemicals enter the eye(s), the eye(s) should be immediately
flushed with tempered potable water from a gently flowing source for at least 15 minutes. The
eyelids should be held away from the eyeball, while the eyeball is moved up, down, and sideways
to wash behind the eyelid(s). Assistance is absolutely necessary at this time. If contact lenses are
worn, they should be removed as soon as possible to allow complete rinsing of the eye(s).
10.10 Dealing with Medical Help
Medical personnel should be fully informed about the chemical involved in the spill and the
circumstances of the spill. Whenever possible a safety data sheet should be provided to the
medical person providing assistance.
34
10.11 Other Accidents Involving Personal Injury
Anyone overcome with smoke or fumes should be removed to uncontaminated air and treated for
shock. Potential rescuers should evaluate the possibility of harm to themselves before entering or
remaining in a toxic environment.
If hazardous chemicals are ingested, the first aid treatment shown on the label or in the safety
data sheet should be undertaken.
If an injured person is not breathing, the rescuer should provide mouth-to-mouth resuscitation,
using appropriate methods. Special training is required to provide cardiopulmonary resuscitation
(CPR). Consult the local Red Cross for details.
Bleeding should be controlled by compressing the wound with a clean cloth or other appropriate
compress. However, because of the possibility of infection with one or more bloodborne
pathogens, such as the HIV virus, adequate personal protection should be used. The injury
should be elevated above the level of the heart. After bleeding is controlled, the injured person
should be covered to avoid shock. Medical attention should be called for as soon as possible.
If a person is in contact with a live electrical circuit, the power should be shut off at the most
convenient switch. The person should not be touched until the power has been disconnected.
10.12 General Chemical Spills
All spills should be cleaned up promptly. Any individual at risk of involvement should be
warned about the spill. Local procedures should be established and followed for determining
when evacuation is necessary.
The spread of chemicals in a spill is important, and so absorbent material should be used to
surround the spill area. After the spill has been contained, it can be cleaned up with appropriate
tools, including commercial spill control kits, for example. If the spilled material is a hazardous
chemical, that chemical and all the cleanup material must be treated as hazardous chemical waste
and properly disposed.
10.13 Accident Reports
All accidents and near accidents should be carefully investigated. The results of that
investigation and recommendations for the prevention of similar occurrences should be
forwarded to the Department Chair and Chemical Hygiene Officer. Accident reports should be
kept on file, as indicated in the record-keeping section of this document.
Section 11: SPILL RESPONSE PROCEDURES
11.1 Personal Injury
35
In the event of a spill, the first response should be to determine if anyone has come in contact
with the spilled chemical. All persons who have been splashed should be assisted to the deluge
shower. A minimum 15-minute rinse is indicated. Remember if clothing is splashed, it must all
be removed, since the rinse is designed to remove chemicals only from the skin. Any suggestion
of splash in the eyes requires a 15-minute rinse at the eye wash. Hold the eyelids open and allow
the water to rinse the eye surface. If contact lenses are worn, they should be removed as soon as
possible to allow complete rinsing of the eye.
11.2 Identification of the Spill
If the spill appears to be organic solvents, ammonia, or other volatile reagents, evacuate the area
as soon as possible. Use fire drill procedures and ventilate the area. Be aware of the possibility
of sparks from electrical switches, open flames, or other sources of ignition.
If the chemical involved in the spill is judged to present an immediate hazard, the evacuation is
to be absolute, and the area isolated until a HAZMAT team is called.
11.3 Containment of the Spill
If there is no immediate danger to personnel, containment should be accomplished by use of spill
pillows, towels, rolls, or other devices that will keep it from spreading.
If practical, a dam to contain the spill may be formed using coarse vermiculite, kitty litter, or
another absorbent material.
Another inexpensive sorbent can be made from a mixture of sand and sodium carbonate. This is
particularly effective with corrosives because the soda will neutralize acids, and the sand
improves the footing and minimizes the possibility of slipping and falling into the spill. The use
of sodium bicarbonate is also effective, and it will neutralize caustic spills.
11.4 Cleanup
If hazardous vapors are present, the area should be isolated. Only persons trained in the use of
respirators may enter the area. This will frequently mean waiting for the arrival of the HAZMAT
team.
Cleanup can proceed once the area is vented and the spill is contained. Mops, shovels, scoops,
and buckets can be used in the usual manner.
Once the spill is thoroughly absorbed, the waste should be collected in heavy plastic bags, clearly
labeled, and isolated for disposal.
After all hazardous material has been removed, cleanup can be completed using standard
custodial cleaning procedures.
36
11.5 Protective Equipment
Protective equipment to be used in the cleanup process should include chemical splash goggles,
face shields, heavy rubber gloves, coveralls or aprons or lab coats, and either rubber boots or
plastic over-the-shoe protectors.
In no case should the cleanup of a major spill be undertaken by one not trained in these
procedures. No one should work alone. The buddy system is essential to protect the workers.
Further, the cleanup team should not begin work before contacting the Chemical Hygiene Officer
or other appropriate authorities.
11.6 Training Requirements
To undertake the cleanup of a major or extremely hazardous spill, all responders should have
Hazardous Waste Operations and Emergency Response (HAZWOPER) training. This training is
available at various levels:
11.6.1 The “First Responder at the Awareness Level” must understand the nature of hazardous
materials and the associated risks, recognize the presence of hazardous materials in an
emergency, and understand the first responder’s role in the College’s emergency response plan,
which is to determine risk, assist injured, evacuate, and call for assistance.
11.6.2 The “First Responder at the Operating Level” will know the basic hazard and risk-
assessment techniques and terms, will select and use proper personal protective equipment, will
perform basic control, containment, and/or confinement operations using the capabilities
available within the school, will implement basic decontamination procedures, and will
understand the relevant standard operating procedures and termination procedures.
11.6.3 “HAZWOPER Third-and Fourth-Level Response” will require a trained HAZMAT team,
i.e., the fire department.
11.6.4 Training for all laboratory workers should include awareness level training which is
reviewed on an annual basis. The second level, the operations response team, should have
training sessions at least twice a year. If possible, this should be coordinated with local
HAZMAT, fire department, or other emergency response teams to improve efficiency during an
incident.
11.7 Disposal
If the spilled material was a hazardous chemical, all of the materials involved in the cleanup will
usually be considered hazardous waste and must be disposed of as such.
In those few instances in which the cleanup transformed the material to a nonhazardous form, the
cleanup residue may be disposed of in a local sanitary landfill. Check with local landfill
authorities before attempting to do this.
37
11.8 Record-Keeping
Complete records of the incident, including injuries, witnesses, response and cleanup procedures,
waste disposal, additional assistance, and final evaluation will be collected for the Department.
Chemical Hygiene Officer and/or the Environmental Health and Safety Officer.

Foreword
As guidance for each employer's development of an appropriate
laboratory Chemical Hygiene Plan, the following non-mandatory
recommendations are provided. They were extracted from
"Prudent Practices for handling Hazardous Chemical in
Laboratories" (referred to below as "Prudent Practices"), which
was published in 1981 by the National Research Council and is
available from the National Academy Press, 2101 Constitution
Ave., NW., Washington DC 20418.
"Prudent Practices" is cited because of its wide distribution and
acceptance and because of its preparation by members of the
laboratory community through the sponsorship of the National
Research Council. However, none of the recommendations given
here will modify any requirements of the laboratory standard. This
Appendix merely presents pertinent recommendations from
"Prudent Practices", organized into a form convenient for quick
reference during operation of a laboratory facility and during
development and application of a Chemical Hygiene Plan. Users
of this appendix should consult "Prudent Practices" for a more
extended presentation and justification for each recommendation.
"Prudent Practices" deals with both safety and chemical hazards
while the laboratory standard is concerned primarily with chemical
hazards. Therefore, only those recommendation directed primarily
toward control of toxic exposures are cited in this appendix, with
the term "chemical hygiene" being substituted for the word
"safety". However, since conditions producing or threatening
physical injury often pose toxic risks as well, page references
concerning major categories of safety hazards in the laboratory are
given in section F.
The recommendations from "Prudent Practices" have been
paraphrased, combined, or otherwise reorganized, and headings
have been added. However, their sense has not been changed.
Corresponding Sections of the Standard and this Appendix
The following table is given for the convenience of those who
are developing a Chemical Hygiene Plan which will satisfy the
requirements of paragraph (e) of the standard. It indicates those

(Reference to page numbers in "Prudent Practices" are given in
parentheses.)
A. General Principles for Work with Laboratory Chemicals
In addition to the more detailed recommendations listed below
in sections B-E, "Prudent Practices" expresses certain general
principles, including the following:
1. It is prudent to minimize all chemical exposures. Because
few laboratory chemicals are without hazards, general precautions
for handling all laboratory chemicals should be adopted, rather
than specific guidelines for particular chemicals (2, 10). Skin
contact with chemicals should be avoided as a cardinal rule (198).
2. Avoid underestimation of risk. Even for substances of no
known significant hazard, exposure should be minimized; for work
with special precautions should be taken 910, 37, 38). One should
assume that any mixture will be more toxic than its most toxic
component (30,103) and that all substances of unknown toxicity
are toxic (3, 34).
3. Provide adequate ventilation. The best way to prevent
exposure to airborne substances is to prevent their escape into the
working atmosphere by use of hoods and other ventilation devices
(32, 198).
4. Institute a chemical hygiene program. A mandatory chemical
hygiene program designed to minimize exposures is needed; it
should be a regular, continuing effort, not merely a standby or
short-term activity (6, 11). Its recommendations should be
followed in academic teaching laboratories as ell as by full-time
laboratory workers (13).
5. Observe the PELs, TLVs. The Permissible Exposure Limits
of OSHA and the Threshold Limit Values of the American
Conference of Governmental Industrial Hygienists should not be
exceeded (13).
B. Chemical Hygiene Responsibilities
Responsibility for chemical hygiene rest at all levels (6, 11, 21)
including the:
1. Chief executive officer, who has ultimate responsibility for
chemical hygiene within the institution, and must with other
administrators, provide continuing support for institutional
chemical hygiene (7, 11).
2. Supervisor of the department or other administrative unit,
who is responsible for chemical hygiene in that unit (7).
3. Chemical hygiene officer(s), whose appointment is essential
(7) and who must:
(a) Work with administrators and other employees to develop
and implement appropriate chemical hygiene policies and practices
(7);
(b) Monitor procurement, use, and disposal of chemicals used in
the lab (8);
(c) See that appropriate audits are maintained (8);
(d) Help project directors develop precautions and adequate
facilities (10);
(e) Know the current legal requirements concerning regulated
substances (50); and
(f) Seek ways to improve the chemical hygiene program (8, 11).
4. Laboratory supervisor, who has overall responsibility for
chemical hygiene in the laboratory (21) including responsibility to:
(a) Ensure that workers know and follow the chemical hygiene
rules, that protective equipment is available and in working order,
and that appropriate training has been provided (21, 22);
(b) Provide regular, formal chemical hygiene and housekeeping
inspections including routine inspections of emergency equipment
(21, 171);
(c) Know the current legal requirements concerning regulated
substances (50, 231);
(d) Determine the required levels of protective apparel and
equipment (156, 160, 162); and
(e) ensure that facilities and training for use of any material
being ordered are adequate (215).
5. Project director or director of other specific operation, who
has primary responsibility for chemical hygiene procedures for that
operation (7).
6. Laboratory worker, who is responsible for:
(a) Planning and conducting each operation in accordance with
the institutional chemical hygiene procedures (7, 21, 22, 230); and
(b) Developing good personal chemical hygiene habits (22).
C. The Laboratory Facility
1. Design. The laboratory facility should have:
(a) An appropriate general ventilation system (see C4 below)
with air intakes and exhausts located so as to avoid intake of
contaminated air (194);
(b) Adequate, well-ventilated stockrooms/storerooms (218,
219);
(c) Laboratory hoods and sinks (12, 162);
(d) Other safety equipment including eyewash fountains and
drench showers (162, 169); and
(e) Arrangements for waste disposal (12, 240).
2. Maintenance. Chemical-hygiene-related equipment (hoods,
incinerator, etc.) should undergo continuing appraisal and be
modified if inadequate (11, 12).
3. Usage. The work conducted (10) and its scale (12) must be
appropriate to the physical facilities available and, especially, to
the quality of ventilation (13).
4. Ventilation.-(a) General laboratory ventilation. This system
should: Provide a source of air for breathing and for input to local
ventilation devices (199); it should not be relied on for protection
from toxic substances released into the laboratory (198); ensure
that laboratory air is continually replaced, preventing increase of
air concentrations of toxic substances during the working day
(194); direct air flow into the laboratory from non-laboratory areas
and out to the exterior of the building (194).
(b) Hoods. A laboratory hood with 2.5 linear feet of hood space
per person should be provided for every 2 workers if they spend
most of their time working with chemicals (199); each hood should
have a continuous monitoring device to allow convenient
confirmation of adequate hood performance before use (200, 209).
If this is not possible, work with substances of unknown toxicity
should be avoided (13) or other types of local ventilation devices
should be provided (199). See pp. 201-206 for a discussion of
hood design, construction, and evaluation.
(c) Other local ventilation devices. Ventilated storage cabinets,
canopy hoods, snorkels, etc. should be provided as needed (199).
Each canopy hood and snorkel should have a separate duct (207).
(d) Special ventilation areas. Exhaust air from glove boxes and
isolation rooms should be passed through scrubbers or other
treatment before release into the regular exhaust system (208).
Cold rooms and warm rooms should have provisions for rapid
escape in the event of electrical failure (209).
(e) Modifications. Any alteration of the ventilation system
should be made only if thorough testing indicates that worker
protection from airborne toxic substances will continue to be
adequate (12, 193, 204).
(f) Performance. Rate: 4-12 room air changes/hour is normally
adequate general ventilation if local exhaust systems such as hoods
are used as the primary method of control (194).
(g) Quality. General air flow should not be turbulent and should
be relatively uniform throughout the laboratory, with no high
velocity or static areas (194,195); airflow into and within the hood
should not be excessively turbulent (200); hood face velocity
should be adequate (typically 60-100 lfm) (200, 204).
(h) Evaluation. Quality and quantity of ventilation should be
evaluated on installation (202), regularly monitored ( at least every
3 months) (6, 12, 14, 195), and reevaluated whenever a change in
local ventilation devices is made (12, 195, 207). See pp. 195-198
for methods of evaluation and for calculation of estimated airborne
contaminant concentrations.
D. Components of the chemical Hygiene Plan
1. Basic Rules and Procedures
(Recommendations for these are given in section E, below)
2. Chemical Procurement, Distribution, and Storage
(a) Procurement. Before a substance is received, information
on proper handling, storage, and disposal should be known to those
who will be involved (251, 216). No container should be accepted
without an adequate identifying label (216).
(b) Stockrooms/storerooms. Toxic substances should be
segregated in a well-identified area with local exhaust ventilation
(221). Chemicals which are highly toxic (227) or other chemicals
whose containers have been opened should be in unbreakable
secondary containers (219). Stored chemicals should be examined
periodically (at least annually) for replacement, deterioration, and
container integrity (218-19).
Stockrooms/storerooms should not be used as preparation or
repackaging areas, should be open during normal working hours,
and should be controlled by one person (219).
(c) Distribution. When chemicals are hand carried, the
container should be placed in an outside container or bucket.
Freight-only elevators should be used if possible (223).
(d) Laboratory storage. Amounts permitted should be as small
as practical. Storage on bench tops and in hoods is inadvisable.
Exposure to heat or direct sunlight should be avoided. Periodic
inventories should be conducted, with unneeded items being
discarded or returned to the storeroom/stockroom (225-6, 229).
3. Environmental Monitoring
Regular instrumental monitoring of airborne concentration is
not usually justified or practical in laboratories but may be
appropriate when testing or redesigning hoods or other ventilation
devised (12) or when a highly toxic substance is stored or used
regularly (e.g., 3 times/week) (13).
4. Housekeeping, Maintenance, and Inspections
(a) Cleaning. Floors should be cleaned regularly (24).
(b) Inspections. Formal housekeeping and chemical hygiene
inspections should be held at least quarterly (6, 21) for units which
have frequent personnel changes and semiannually for other;
informal inspections should be continual (21).
(c) Maintenance. Eye wash fountains should be inspected at
intervals of not less than 3 months (6). Respirators for routine use
should be inspected periodically by the laboratory supervisor
(169). Safety showers should be tested routinely (169). Other
safety equipment should be inspected regularly. (e.g., every 3-6
months) (6, 24,171). Procedures to prevent restarting of out-of-
service equipment should be established (25).
(d) Passageways. Stairways and hallways should not be used as
storage areas (24). Access to exits, emergency equipment, and
utility controls should never be blocked (24).
5. Medical Program
(a) Compliance with regulations. Regular medical surveillance
should be established to the extent required by regulations (12).
(b) Routine surveillance. Anyone whose work involves regular
and frequent handling of toxicologically significant quantities of a
chemical should consult a qualified physician to determine on an
individual basis whether a regular schedule of medical surveillance
is desirable (11, 50).
(c) First aid. Personnel trained in first aid should be available
during working hours and an emergency room with medical
personnel should be nearby (173). See pp. 176-178 for description
of some emergency first aid procedures.
6. Protective Apparel and Equipment
These should include for each laboratory:
(a) Protective apparel compatible with the required degree of
protection for substance being handled (158-161);
(b) An easily accessible drench-type safety shower (162, 169);
(c) An eyewash fountain (162);
(d) A fire extinguisher (162-164);
(e) Respiratory protection (164-9), fire alarm and telephone for
emergency use (162) should be available nearby; and
(f) Other items designated by the laboratory supervisor (156,
160).
7. Records
(a) Accident records should be written and retained (174).
(b) Chemical Hygiene Plan records should document that the
facilities and precautions were compatible with current knowledge
and regulations (7).
(c) Inventory and usage records for high-risk substances should
be kept as specified in sections E3e below.
(d) Medical records should be retained by the institution in
accordance with the requirements of state and federal regulations
(12).
8. Signs and Labels
Prominent signs and labels of the following types should be
posted:
(a) Emergency telephone numbers of emergency
personnel/facilities, supervisors, and laboratory workers (28);
(b) Identity labels, showing contents of containers (including
waste receptacles) and associated hazards (27, 48);
(c) Locations signs for safety showers, eyewash stations, other
safety and first aid equipment, exits (27) and areas where food and
beverage consumption and storage are permitted (24); and
(d) Warnings at areas or equipment where special or unusual
hazards exist (27).
9. Spills and Accidents
(a) A written emergency plan should be established and
communicated to all personnel; it should include procedures for
ventilation failure (200), evacuation, medical care, reporting, and
drills (172).
(b) There should be an alarm system to alert people in all parts
of the facility including isolation areas such as cold rooms (172).
(c) A spill control policy should be developed and should
include consideration of prevention, containment, cleanup, and
reporting (175).
(d) All accidents or near accidents should be carefully analyzed
with the results distributed to all who might benefit (8, 28).
10. Information and Training Program
(a) Aim: To assure that all individuals at risk are adequately
informed about the work in the laboratory, its risks, and what to do
if an accident occurs (5, 15).
(b) Emergency and Personal Protection Training: Every
laboratory worker should know the location and proper use of
available protective apparel and equipment (154, 169).
Some of the full-time personnel of the laboratory should be
trained in the proper use of emergency equipment and procedures
(6).
Such training as well as first aid instruction should be available
to (154) and encouraged for (176) everyone who might need it.
(c) Receiving and stockroom/storeroom personnel should know
about hazards, handling equipment, protective apparel, and
relevant regulations (217).
(d) Frequency of Training: The training and education program
should be a regular, continuing activity-not simply an annual
presentation (15).
(e) Literature/Consultation: Literature and consulting advice
concerning chemical hygiene should be readily available to
laboratory personnel, who should be encouraged to use these
information resources (14).
11. Waste Disposal Program
(a) Aim: To assure that minimal harm to people, other
organisms, and the environment will result from the disposal of
waste laboratory chemicals (5).
(b) Content (14,232, 233, 240): The waste disposal program
should specify how waste is collected, segregated, stored, and
transported and include consideration of what materials can be
incinerated. Transport from the institution must be in accordance
with DOT regulations (244).
(c) Discarding Chemical Stocks: Unlabeled containers of
chemicals and solutions should undergo prompt disposal; if
partially used, they should not be opened (24, 270.
Before a worker's employment in the laboratory ends, chemicals
for which that person was responsible should be discarded or
returned to storage (226).
(d) Frequency of Disposal: Waste should be removed from
laboratories to a central waste storage area at least once per week
and from the central waste storage area at regular intervals (14).
(e) Method of Disposal: Incineration in an environmentally
acceptable manner is the most practical disposal method for
combustible laboratory waste (14, 238, 241).
Indiscriminate disposal by pouring waste chemicals down the
drain (14, 231,242) or adding them to mixed refuse for landfill
burial is unacceptable (14).
Hoods should not be used as a means of disposal for volatile
chemical (40, 200).
Disposal by recycling (233, 243) or chemical decontamination
should be used when possible.
E. Basic Rules and Procedures for Working with Chemicals
The Chemical Hygiene Plan should require that laboratory
workers know and follow its rules and procedures. In addition to
the procedures of the sub programs mentioned above, these should
include the rules listed below.
1.General Rules
The following should be used for essentially all laboratory work
with chemicals:
(a) Accidents and spills-eye Contact: Promptly flush eyes with
water for a prolonged period (15 minutes) and seek medical
attention (33, 172).
Ingestion: Encourage the victim to drink large amounts of water
(178).
Skin Contact: Promptly flush the affected area with water (33,
172, 178) and remove any contaminated clothing (172, 178). If
symptoms persist after washing, seek medical attention (33).
Clean-up. Promptly clean up spills, using appropriate protective
apparel and equipment and proper disposal (24, 33). See pp. 233-
237 for specific clean-up recommendations.
(b) Avoidance of "routine" exposure; Develop and encourage
safe habits (230; avoid unnecessary exposure to chemicals by any
route (23);
Do not smell or taste chemicals (32). Vent apparatus which may
discharge toxic chemicals (vacuum pumps, distillation columns,
etc.) into local exhaust devices (199).
Inspect gloves (157) and test glove boxes (208) before use.
Do not allow release of toxic substances in cold rooms and
worm rooms, since these have contained recirculated atmospheres
(209).
(c) Choice of chemicals: Use only those chemicals for which the
quality of the available ventilation system is appropriate (13).
(d) Eating, smoking, etc.: Avoid eating, drinking, smoking, gum
chewing, or application of cosmetics in areas where laboratory
chemicals are present (22, 24, 32, 40); wash hands before
conducting these activities.
Avoid storage, handling, or consumption of food or beverages
in storage areas, refrigerators, glassware or utensils which are also
used for laboratory operations (23, 24, 226).
(e)Equipment and glassware: handle and store laboratory
glassware with care to avoid damage; do not use damaged
glassware (250. Use extra care with Dewar flasks and other
evacuated glass apparatus; shield or wrap them to contain
chemicals and fragments should implosion occur (25). Use
equipment only for its designed purpose (23, 26).
(f) Exiting: Wash areas of exposed skin well before leaving the
laboratory (23).
(h) Horseplay: Avoid practical jokes or other behavior which
might confuse, startle or distract another worker (23).
(i) Personal apparel: Confine long hair and loose clothing (23,
158). Wear shoes at all time in the laboratory but do not wear
sandals, perforated shoes, or sneakers (158).
(j) Personal housekeeping: Keep the work area clean and
uncluttered, with chemicals and equipment being properly labeled
and stored; clean up the work area on completion of an operation
or at the end of each day (24).
(k) Personal protection: Assure that appropriate eye protection
(154-156) is worn by all persons, including visitors, where
chemicals are stored or handled (22, 23, 33, 154).
Wear appropriate gloves when the potential for contact with
toxic materials exists (157); inspect the gloves before each use,
wash them before removal, and replace them periodically (157). (A
table of resistance to chemicals of common glove materials is
given p. 159).
Use appropriate (164-168) respiratory equipment when air
contaminant concentrations are not sufficiently restricted by
engineering controls (164-5), inspecting the respirator before use
(169).
Use any other protective and emergency apparel and equipment
as appropriate (22, 157-162).
Avoid use of contact lenses in the laboratory unless necessary;
if they are used, inform supervisor so special precautions can be
taken (155).
Remove laboratory coats immediately on significant
contamination (161).
(l) Planning: Seek information and advice about hazards (7),
plan appropriate protective procedures, and plan positioning of
equipment before beginning any new operation (22, 23).
(m) Unattended operations: Leave lights on, place an
appropriate sign on the door, and provide for containment of toxic
substance in the event of failure of a utility service (such as cooling
water) to an unattended operation (27, 128).
(n) Use of hood: use the hood for operations which might result
in release of toxic chemical vapors or dust (198-9).
As a rule of thumb, use a hood or other local ventilation device
when working with any appreciably volatile substance with a TLV
of less that 50 ppm (13).
Confirm adequate hood performance before use; keep hood
closed at all times except when adjustments within the hood are
being made (200); keep materials stored in hoods to a minimum
and do not allow them to block vents or air flow (200).
Leave the hood "on" when it is not in active use if toxic
substances are stored in it or if it is uncertain whether adequate
general laboratory ventilation will be maintained when it is "off"
(200).
(o) Vigilance: Be alert to unsafe conditions and see that they are
corrected when detected (22).
(p) Waste disposal: Assure that the plan for each laboratory
operation includes plans and training for waste disposal (230).
Deposit chemical waste in appropriately labeled receptacles and
follow all other waste disposal procedures of the Chemical
Hygiene Plan (22, 24).
Do not discharge to the sewer concentrated acids or bases (231);
highly toxic, malodorous, or lachrymatory substances (231); or any
substances which might interfere with the biological activity of
waste water treatment plants, create fire or explosion hazards,
cause structural damage or obstruct flow (242).
(q) Working alone: Avoid working alone in a building; do not
work alone in a laboratory if the procedures being conducted are
hazardous (28).
2. Working with Allergens and Embryotoxins
(a) Allergens (examples: diazomethane, isocyanates,
bichromates): Wear suitable gloves to prevent hand contact with
allergens or substances of unknown allergenic activity (35).
(b) Embryotoxins (34-5) (examples: organomercurials, lead
compounds, formamide): If you are a woman of childbearing age,
handle these substances only in a hood whose satisfactory
performance has been confirmed, using appropriate protective
apparel (especially gloves) to prevent skin contact.
Review each use of these materials with the research supervisor
and review continuing uses annually or whenever a procedural
change is made.
Store these substances, properly labeled, in an adequately
ventilated area in an unbreakable secondary container.
Notify supervisors of all incidents of exposure or spills; consult
a qualified physician when appropriate.
3. Work with Chemicals of Moderate Chronic or High Acute
Toxicity
Examples: diisopropylfluorophosphate (41), hydrofluoric acid
(43), hydrogen cyanide (45).
Supplemental rules to be followed in addition to those mention
above (Procedure B of "Prudent Practices"' pp. 39-41):
(a) Aim: To minimize exposure to these toxic substances by any
route using all reasonable precautions (39).
(b) Applicability: These precautions are appropriate for
substances with moderate chronic or high acute toxicity used in
significant quantities (39).
(c) Location: use and store these substances only in areas of
restricted access with special warning signs (40, 229).
Always use a hood (previously evaluated to confirm adequate
performance with a face velocity of at least 60 linear feet per
minute) (40) or other containment device for procedures which
may result in the generation of aerosols or vapors containing the
substance (39); trap released vapors to prevent their discharge with
the hood exhaust (40).
(d) Personal protection: Always avoid skin contact by use of
gloves and long sleeves (and other protective apparel as
appropriate) (39). Always wash hands and arms immediately after
working with these materials (40).
(e) Records: Maintain records of the amounts of these materials
on hand, amounts used, and the names of the workers involved (40,
229).
(f) Prevention of spills and accidents: Be prepared for accidents
and spills (41).
Assure that at least 2 people are present at all times if a
compound in use is highly toxic or of unknown toxicity (39).
Store breakable containers of these substances in chemically
resistant trays; also work and mount apparatus above such tray or
cover work and storage surfaces with removable, absorbent, plastic
backed paper (40).
If a major spill occurs outside the hood, evacuate the area;
assure that cleanup personnel wear suitable protective apparel and
equipment (41).
(g) Waste: Thoroughly decontaminate or incinerate
contaminated clothing or shoes (41). If possible, chemically
decontaminate by chemical conversion (40).
Store contaminated waste in closed, suitably labeled,
impervious containers (for liquids, in glass or plastic bottles half-
filled with vermiculite) (40).
4. Work with chemicals of High Chronic Toxicity
(Examples: dimethylmercury and nickel carbonyl (48), benzo-a-
pyrene (51), N-nitrosodiethylamine (54), other human carcinogens
or substances of known high chronic toxicity (in quantities above a
few milligrams to a few grams, depending on the substance) (47).
(Procedure A of "Prudent Practices" pp. 47-50).
(a) Access: Conduct all transfers and work with these substances
in a "controlled area": a restricted access hood, glove box, or
portion of a lab, designated for use of highly toxic substances, for
which all people with access are aware of the substance being used
and necessary precautions (48).
(b) Approvals: Prepare a plan for use and disposal of these
materials and obtain the approval of the laboratory supervisor (48).
(c) Non-contamination/Decontamination: protect vacuum
pumps against contamination by scrubbers or HEPA filters and
vent them into the hood (49). Decontaminate vacuum pumps or
other contaminated equipment, including glassware, in the hood
before removing them from the controlled area (49, 50).
Decontaminate the controlled area before normal work is
resumed there (50).
(d) Exiting: On leaving a controlled area, remove any protective
apparel (placing it in an appropriate, labeled container) and
thoroughly wash hands, forearms, face, and neck (49).
(e) Housekeeping: Use a wet mop or a vacuum cleaner equipped
with a HEPA filter instead of dry sweeping if the toxic substance
was a dry powder (50).
(f) Medical surveillance: If using toxicologically significant
quantities of such a substance on a regular basis (e.g., 3 times per
week), consult a qualified physician concerning desirability of
regular medical surveillance (50).
(g) Records: Keep accurate records of the amounts of these
substances stored (229) and used, the dates of use, and names of
users (48).
(h) Signs and labels: Assure that the controlled area is
conspicuously marked with warning and restricted access signs
(49) and that all containers of these substances are appropriately
labeled with identity and warning labels (48).
(i) Spills: Assure that contingency plans, equipment, and
materials to minimize exposures of people and property in case of
accident are available (233-4).
(j) Storage: Store containers of these chemicals only in a
ventilated, limited access (48, 227, 229) area in appropriately
labeled, unbreakable, chemically resistant, secondary containers
(48, 229).
(k) Glove boxes: For a negative pressure glove box, ventilation
rate must be at least 2 volume changes/hour and pressure at least
0.5 inches of water (48). For a positive pressure glove box,
thoroughly check for leaks before each use (49). In either case,
trap exit gases of filter them through a HEPA filter and then
release them into the hood (49).
(l) Waste: Use chemical decontamination whenever possible;
ensure that containers of contaminated waste (including washings
from contaminated flasks) are transferred from the controlled area
in a secondary container under the supervision of authorized
personnel (49, 50, 233).
5. Animal Work with Chemicals of High Chronic Toxicity
(a) Access: For large scale studies, special facilities with
restricted access are preferable (56).
(b) Administration of the toxic substance: When possible,
administer the substance by injection or gavage instead of in the
diet. If administration is in the diet, use a caging system under
negative pressure or under laminar air flow directed toward HEPA
filters (56).
(c) Aerosol suppression: Devise procedures which minimize
formation and dispersal of contaminated aerosols, including those
form food, urine, and feces (e.g., use HEPA filtered vacuum
equipment for cleaning, moisten contaminated bedding before
removal from the cage, mix diets in closed containers in a hood)
(55, 56).
(d) Personal protection: When working in the animal room,
wear plastic or rubber gloves, fully buttoned laboratory coat or
jumpsuit and, if needed because of incomplete suppression of
aerosols, other apparel and equipment (shoe and head coverings,
respirator) (56).
(e) Waste disposal: Dispose of contaminated animal tissues and
excreta by incineration if the available incinerator can convert the
contaminant to non-toxic products (238); otherwise package the
waste appropriately for burial in an EPA-approved site (239).
F. Safety Recommendations
The above recommendations from "Prudent Practices" do not
include those which are directed primarily toward prevention of
physical injury rather than toxic exposure. However, failure of
precautions against injury will often have the secondary effect of
causing toxic exposures. Therefore, we list below page references
for recommendations concerning some of the major categories of
safety hazards which also have implications for chemical hygiene:
1. Corrosive agents: (35-6)
2. Electrically powered laboratory apparatus: (179-92)
3. Fires, explosions: (26, 57-74, 162-4, 174-5,219-20, 226-7)

§ 1910.104 Oxygen.
(a) Scope. This section applies to the
installation of bulk oxygen systems on
industrial and institutional consumer
premises. This section does not apply
to oxygen manufacturing plants or
other establishments operated by the
oxygen supplier or his agent for the
purpose of storing oxygen and refilling
portable containers, trailers, mobile
supply trucks, or tank cars, nor to sys-
tems having capacities less than those
stated in paragraph (b)(1) of this sec-
tion.
(b) Bulk oxygen systems—(1) Definition.
As used in this section: A bulk oxygen
system is an assembly of equipment,
such as oxygen storage containers,
pressure regulators, safety devices, va-
porizers, manifolds, and inter-
connecting piping, which has storage
capacity of more than 13,000 cubic feet
of oxygen, Normal Temperature and
Pressure (NTP), connected in service or
ready for service, or more than 25,000
cubic feet of oxygen (NTP) including
unconnected reserves on hand at the
site. The bulk oxygen system termi-
nates at the point where oxygen at
service pressure first enters the supply
line. The oxygen containers may be
stationary or movable, and the oxygen
may be stored as gas or liquid.
(2) Location—(i) General. Bulk oxygen
storage systems shall be located above
ground out of doors, or shall be in-
stalled in a building of noncombustible
construction, adequately vented, and
used for that purpose exclusively. The
location selected shall be such that
containers and associated equipment
shall not be exposed by electric power
lines, flammable or combustible liquid
lines, or flammable gas lines.
(ii) Accessibility. The system shall be
located so that it is readily accessible
to mobile supply equipment at ground
level and to authorized personnel.
(iii) Leakage. Where oxygen is stored
as a liquid, noncombustible surfacing
shall be provided in an area in which
any leakage of liquid oxygen might fall
during operation of the system and fill-
ing of a storage container. For pur-
poses of this paragraph, asphaltic or bi-
tuminous paving is considered to be
combustible.
(iv) Elevation. When locating bulk ox-
ygen systems near above-ground flam-
mable or combustible liquid storage
which may be either indoors or out-
doors, it is advisable to locate the sys-
tem on ground higher than the flam-
mable or combustible liquid storage.
(v) Dikes. Where it is necessary to lo-
cate a bulk oxygen system on ground
lower than adjacent flammable or com-
bustible liquid storage suitable means
shall be taken (such as by diking, di-
version curbs, or grading) with respect
to the adjacent flammable or combus-
tible liquid storage to prevent accumu-
lation of liquids under the bulk oxygen
system.
(3) Distance between systems and expo-
sures—(i) General. The minimum dis-
tance from any bulk oxygen storage
container to exposures, measured in
the most direct line except as indicated
in paragraphs (b)(3) (vi) and (viii) of
this section, shall be as indicated in
paragraphs (b)(3) (ii) to (xviii) of this
section inclusive.
(ii) Combustible structures. Fifty feet
from any combustible structures.
(iii) Fire resistive structures. Twenty-
five feet from any structures with fire-
resistive exterior walls or sprinklered
buildings of other construction, but
not less than one-half the height of ad-
jacent side wall of the structure.
(iv) Openings. At least 10 feet from
any opening in adjacent walls of fire
resistive structures. Spacing from such
structures shall be adequate to permit
maintenance, but shall not be less than
1 foot.
(v) Flammable liquid storage above-
ground.
Distance (feet) Capacity (gallons)
50 .................................................. 0 to 1000.
90 .................................................. 1001 or more.
(vi) Flammable liquid storage below-
ground.

pull valve. Should deliver tepid, potable water for at least
15 minutes without need to hold valve.
Eye wash fountain Should deliver tepid, potable water to both eyes.
Should provide a steady, gentle flow for at least 15 minutes
without need to hold valve.
Fire blanket, wool Most useful to keep a victim warm while waiting for
medical attention. A blanket should be available but not on
a roller. The purpose of the blanket is to cover the victim,
Not encircle. Wrapping a burning victim may cause
additional burns to neck and face due to the chimney effect.
Fire extinguisher Should be suitable for Class A, B & C fires.

linear feet per minute.
Should be vented to the outside.
May have a vertical or horizontal sash.
Should be kept clean and uncluttered.
Safety cans Some occasions demand that volatile,
flammable or combustible solvents be stored
in safety cans. Each can should have a
flame arrestor in good working order.
Check local fire codes and NFPA standards 30 and 45.
Signs Signs are useful for designating the location of safety
equipment, means of ingress and egress, etc.
Signs should be chosen to be in conformity with
state guidelines and recommendations.
Smoke alarm Check local fire codes.
Laboratory Spill Protection
General purpose A general purpose adsorbent, such as a mixture of kitty
litter, sand, and vermiculite is suitable for containing
many chemical spills.
