INTRODUCTION
This Chemical Hygiene Plan (CHP) is designed to apply to all Fitchburg State College (FSC) employees who have received chemical hygiene and /or hazardous materials training, as defined in Appendix A (Chemical Hygiene Responsibilities). It shall also be used as a reference by other chemical users on campus, including those using photographic darkrooms and studios. As such, the term “laboratory” refers to any such room when chemicals are used. A detailed description of Laboratory Facilities can be found in Appendix B. The terms used in this Plan can be found in the Glossary located in Appendix C. Resources and Statutory/Regulatory References can be found in Appendix P.
1
1. Basic Rules and Procedures for Working with Chemicals
Everyone on Campus is responsible for recognizing potential hazards in his or her work or study areas. This responsibility requires understanding and familiarity with processes, maintenance of chemical and physical inventories, and periodic review of activities in the work area. A description of Chemical Hazards, as well as information on Chemical Compatibility / Chemical Storage Systems are located in Appendices D and E, respectively.
All FSC employees must be familiar with and follow the rules and procedures contained in this plan.
A. General Rules
The following apply to all work with chemicals:
(1) Avoidance of “routine” exposure
Develop and encourage safe habits; avoid unnecessary exposure to chemicals by any route.
Review Material Safety Data Sheets (MSDS) prior to using a chemical.
Do not taste chemicals.
Do not smell or taste chemicals in an unauthorized manner
Inspect gloves before use.
(2) Choice of chemicals
Users of chemicals are encouraged to develop and use validated experimental procedures that replace hazardous materials with non-hazardous materials, minimize generation of hazardous wastes, or result in effective treatment of wastes to reduce or eliminate hazardous characteristics.
(3) Eating, smoking, etc.
Do not eat, drink, smoke, chew gum, or apply cosmetics in areas where laboratory chemicals are present; wash hands before conducting these activities.
Do not store or handle food or beverages for personal consumption in chemical storage areas, refrigerators, glassware or utensils which are also used for laboratory operations.
(4) Equipment and glassware
Use equipment only for its intended purpose.
Inspect equipment or laboratory apparatus for damage before use. Never use damaged equipment such as cracked glassware or equipment with frayed wiring.
2
Handle and store laboratory glassware with care to avoid damage; do not use damaged glassware. Use extra care with Dewar flasks and other evacuated glass apparatus; shield or wrap them to contain chemicals and fragments should implosion or explosion occur.
(5) Exiting
Wash areas of exposed skin well before leaving the laboratory. A sink, soap and towel will be provided in each chemical use area.
(6) Horseplay
Avoid practical jokes or other behavior which might confuse, startle or distract another worker.
(7) Mouth suction
Do not use mouth suction for pipeting or starting a siphon. Always use a pipette bulb or other mechanical pipette filling device.
(8) Personal apparel
Confine long hair and loose clothing. Sandals, perforated shoes, or absorbent footwear are not appropriate footwear.
Wear clothing that covers both the arms and legs. Wear a lab coat. Do not wear jewelry.
(9) Personal housekeeping
All work areas, including benches and floors must be kept clean, dry, 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.
Access to emergency equipment, electrical panels, emergency shut offs (e.g. gas), fire extinguishers, utility controls, showers, eyewash stations, and laboratory exits must never be blocked. Three square feet of unoccupied area is required around each.
(10) Personal protection
Wear appropriate safety goggles when handling potentially hazardous chemicals or engaging in processes that may endanger the eyes. Safety glasses with side shields may not be appropriate for protection with some chemicals.
Wear appropriate gloves when the potential for contact with toxic materials exists, with glove material compatible with chemicals in use; inspect the gloves before each use, wash them before removal, and replace them periodically.
3
Chemical resistant aprons and laboratory coats with long sleeves shall be worn buttoned (snaps are preferred). Use any other protective and emergency apparel and equipment as appropriate.
Avoid use of contact lenses in the laboratory unless necessary; if they are used, inform supervisor so special precautions can be taken.
Remove laboratory coats immediately on significant contamination.
Refer to CHP Section 3, for more detailed requirements concerning protective apparel.
(11) Planning
Seek information and advice about hazards, plan appropriate protective procedures, and plan positioning of equipment before beginning any new operation.
a. Engineering Controls
Use an appropriate laboratory hood if material is volatile or the process may produce aerosols.
Use appropriate storage containers for raw materials and waste materials (e.g. approved metal flammable safety cans and flammable storage cabinets). (See Appendix F for Maximum Allowable Sizes of Containers and Portable Tanks.)
b. Administrative Controls
Have an appropriate Standard Operating Procedure (SOP) available for chemicals and procedures. A chemical spill and waste disposal protocol must be included in the SOP. See Appendix N, and Appendix O (part 5) for guidance on developing SOPs. Ensure that all laboratory staff and students are familiar with SOPs. An SOP shall be available for every process and experiment performed in a laboratory, studio or darkroom which shall set out each step of the process and experiment and set out any safety precautions required beyond the safety precautions established by this Plan. If there is no SOP available, lab workers must consult with the department chair prior to beginning any work with chemicals or procedures.
Use appropriate hand protection and wash hands and any other potentially exposed skin immediately after working with chemicals.
Ensure all chemical containers are appropriately labeled (see section 2(A)(1)).
4
If possible, cover work surfaces with absorbent plastic backed paper to simplify clean-up of any spilled chemicals.
Have an appropriate waste disposal plan for chemicals.
Have an appropriate spill plan for chemicals.
If required by Hazard Assessment/Analysis, as set out in Appendix N, conduct exposure monitoring and medical consultations.
(12) Unattended operations
All chemical containers, including reaction vessels and process equipment, must be labeled.
A sign stating “Let Run” (or equivalent) must be posted near the process and on the laboratory door. This sign will include a contact name for person responsible for operation.
Provide for the containment of hazard substances in the event of failure of a utility service, such as cooling water. Additional controls are needed for particularly hazardous chemicals.
(13) Use of hood
Use the hood for operations which might result in release of hazardous chemical vapors or dust.
As a rule of thumb, use a hood or other local ventilation device when working with any appreciably volatile substance with a Threshold Limit Value (TLV) of less than 50 ppm or the equivalent Permissible Exposure Limit (PEL).
Confirm adequate hood performance before use; when not utilizing the exhaust hoods, cover sash to a point 6” above work surface to keep the room under negative pressure; windows and doors to the laboratory should be kept closed; keep materials stored in hoods to a minimum and do not allow them to block vents or air flow.
(14) Vigilance
Be alert to unsafe conditions and see that they are corrected when detected.
(15) Disposal
Deposit chemical wastes in the appropriate, labeled receptacles and follow the disposal procedures described in CHP Section 10.
(16) Working alone
Employees should avoid working alone, when conducting research and experiments involving hazardous substances and procedures.
5
a. Undergraduate Teaching Laboratories:
A college representative trained in chemical safety (faculty member, laboratory technician or other person chosen by the Department Chairperson) must be present in the laboratory at all times when undergraduate students are conducting experiments.
b. Independent Study and Graduate Students:
Students who need to work alone must receive permission from their advisor prior to working alone. If students have approval from their advisor to work alone after normal working hours, they shall contact FSC Campus Police to make them aware of their presence in the facility. FSC Campus Police shall make periodic checks of any laboratory having lone workers. Students working alone should plan a route of escape in case of an emergency. Students working alone should always notify a responsible person about their location and anticipated time of arrival at home or elsewhere. Those persons should be asked to contact the FSC Campus Police within a reasonable time after which the person does not return.
c. Research Laboratories:
Personnel with special need to work alone after hours shall contact FSC Campus Police to make them aware of their presence in the facility. FSC Campus Police shall make periodic checks of any laboratory having lone workers. Laboratory personnel should plan a route of escape in case of emergency. Personnel working alone shall also notify a responsible person about their location and anticipated time of arrival at home or elsewhere. Those persons should be asked to contact the FSC Campus Police within a reasonable time after which the person did not return.
B. Work with Allergens and Embryotoxins
(1) Allergens
(examples: diazomethane, isocyanates, bichromates)
Wear suitable gloves to prevent hand contact with allergens or substances of unknown allergenic activity. Chemical properties or chemical family of the substance will determine which glove type is required.
(2) Embryotoxins
(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.
6
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.
C. Work with Chemicals of Moderate Chronic or High Acute Toxicity
Medium hazard operations are those where any of the following types of chemicals or biological hazards are used:
Flammable or Combustible Liquids or solids (see Appendix G)
Corrosive or Reactive Chemicals (see Appendices H and I)
Contact Hazards
Heavy metals
Neurotoxins
Peroxide or Peroxide forming (see Appendix J)
Lachrymator
Sensitizer
Unstable
Examples: diisopropylflurophosphate, hydrofluoric acid, hydrogen cyanide.
(1) Aim
To minimize exposure to these toxic substances by any route using all reasonable precautions.
(2) Applicability
These precautions are appropriate for substances with moderate chronic or high acute toxicity used in significant quantities.
(3) Location
Use and store these substances only in areas of restricted access with special warning signs.
Always use a hood (previously evaluated to confirm adequate performance with a face velocity of at least 60 linear feet per minute) or other containment device for procedures which may result in the generation of aerosols or vapors containing the substance.
7
(4) Personal protection
Always avoid skin contact by use of gloves and long sleeves (and other protective apparel as appropriate). Always wash hands and arms immediately after working with these materials.
(5) Records
Maintain records of the amounts of these materials on hand, amounts used, and the names of the workers involved.
(6) Prevention of spills and accidents
Be prepared for accidents and spills.
Assure that at least 2 people are present at all times if a compound in use is highly toxic or of unknown toxicity.
Store breakable containers of these substances in chemically resistant trays; also work and mount apparatus above such trays or cover work and storage surfaces with removable, absorbent, plastic backed paper.
If a major spill occurs outside the hood, evacuate the area; assure that cleanup personnel wear suitable protective apparel and equipment.
D. Work with Chemicals of High Chronic Toxicity
High hazard operations include work with particularly hazardous chemicals that are identified as:
Carcinogens (see Appendix L for a Partial List of Carcinogens and Appendix M for Regulated Carcinogens)
Reproductive toxins
Highly Toxic
Severe allergens
Severe Corrosives
Explosives
Pyrophorics
Strong oxidizers
Strong sensitizers
(Examples: dimethylmercury and nickel carbonyl, benzo-a-pyrene, N-nitrosodiethylamine, other human carcinogens or substances with high carcinogenic potency in animals.)
8
(1) Aim
To minimize exposure to these toxic substances by any route using all reasonable precautions.
(2) Applicability
These precautions are appropriate for substances with high chronic toxicity used in significant quantities.
(3) Approvals
Prepare a plan for use and disposal of these materials and obtain the approval of the Department Chairperson and the Environmental Safety Officer.
(4) Location
Conduct all transfers and work with these substances in a "controlled area": a restricted access hood or portion of a lab designated for use of highly toxic substances, for which all people with access are aware of the substances being used and necessary precautions.
Assure that the controlled area is conspicuously marked with warning and restricted access signs and that all containers of these substances are appropriately labeled with identity and warning labels.
Store containers of these chemicals only in a ventilated, limited access area in appropriately labeled, unbreakable, chemically resistant, secondary containers.
(5) Personal protection
Always avoid skin contact by use of gloves and long sleeves (and other protective apparel as appropriate). Always wash hands and arms immediately after working with these materials.
(6) Non-contamination/Decontamination
Protect vacuum pumps against contamination by scrubbers or HEPA filters and vent them into the hood. Decontaminate vacuum pumps or other contaminated equipment, including glassware, in the hood before removing them from the controlled area.
Decontaminate the controlled area before normal work is resumed there.
(7) 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.
9
(8) 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.
(9) 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.
(10) Records
Keep accurate records of the amounts of these substances stored and used, the dates of use, and names of users.
(11) Prevention of spills and accidents
Assure that contingency plans, equipment, and materials to minimize exposures of people and property in case of accident are available.
2. Chemical Procurement, Distribution, and Storage
A. Procurement
Before the approval of any chemical purchases, the current chemical inventory must be checked and the Purchase Order signed-off by the Environmental
Safety Officer (ESO) or his/her designee. This measure prevents the duplicate or unnecessary purchase of chemicals already in inventory, see Section 2A(2), Chemical Inventory.
(1) Chemical Container Labels
a. Chemical labels on original containers shall display the information listed below upon their delivery to the College. Any chemicals delivered to the College shall be inspected for correct labeling upon receipt by the Materials Management Department under the guidance of the Chemical Hygiene Officer (CHO). Containers shall be rejected and sent back to the supplier if the labeling is insufficient.
i The common name of the chemical.
ii The name of the company supplying the chemical.
iii A hazard warning indicating any health or safety hazards that the chemical may present, including: corrosiveness, carcinogenicity, water reactivity, flammability, mutagenicity and toxicity. If a chemical presents a health
10
hazard, the label shall indicate the precautions required (gloves, respirator, etc.) for its safe handling.
b. Upon the delivery of an original container to its point of use, the Lab Technician, together with the Designated User or Principal Investigator in control of the point of use shall be responsible for maintaining the proper labeling of the containers in which the chemical is stored or transported. A chemical may be dispensed from its original container only if it is dispensed into a container that has been (i) approved by the CHO as safe and compatible; and (ii) labeled with the common and scientific name of the chemical and hazards, if any.
c. Container labeling requirements also apply to chemical substances developed in the laboratory. If the composition of the chemical substance is known it should be labeled accordingly. If the chemical produced is a byproduct whose composition is not known it should be labeled and managed as a hazardous waste.
d. Chemical container labeling will be assessed in the routine inspections of laboratories, studios, darkrooms and storage areas. Questions on the use and type of containers shall be referred to the CHO.
e. Anyone who discovers an unlabeled or mislabeled chemical shall promptly contact the CHO. The CHO will dispose of its contents in accordance with the procedures described in CHP Section 10.
(2) Chemical Inventory
a. Each Department (together with any Principal Investigators engaged in research under the Department’s auspices) shall be responsible for developing and maintaining an accurate and current inventory (the “Local Inventory”) of all chemicals used and stored within the department or, in the case of a Principal Investigator, in his or her laboratory. The Department shall maintain the Local Inventory on a computerized database that has been approved and provided by the CHO. Chemicals shall be entered into the Local Inventory immediately upon their arrival at their point of use. The Technicians responsible for each point of use shall report any changes to the Local Inventory to the CHO on a weekly basis.
b. The CHO shall maintain a master inventory (the “Master Inventory”) of all the chemicals and their storage locations on campus. Each chemical shall be entered into the Master Inventory upon the chemical’s arrival at the College. The Master Inventory shall be modified when a chemical is delivered to its point(s) of use and shall indicate a record of the amount of the chemical at the point(s) of use in accordance with the reports provided pursuant to paragraph “a” immediately above. The CHO shall reconcile the
11
Local Inventories with the Master Inventory on a weekly basis and shall promptly investigate any discrepancies.
(3) Material Safety Data Sheets (MSDS)
a. The CHO will be responsible for ensuring that: (i) the proper MSDS accompanies each chemical shipped to the campus; (ii) the master copy of the MSDS is provided to and maintained at the Environmental Safety Office; and (iii) a copy of the MSDS accompanies the chemical upon its delivery to its point of use and/or to the end user. MSDSs shall be available 24 hours a day at the Environmental Safety Office in case of emergency.
b. The Department or the Principal Investigator responsible for the point of use shall maintain a copy of the MSDSs at the point of use.
c. All Designated Users, Principal Investigators, Technicians and student workers should review the MSDS prior to use of a chemical.
B. Transport of Hazardous Chemicals
The following guidelines will be used when transporting hazardous chemicals within facilities or from building to building. Transportation of all chemicals on public ways (streets and roads) is not permitted without proper licensing and proper vehicles.
1. Hazardous chemicals that are hand-carried shall be placed in a secondary container or acid carrying bucket with tight fitting covers and shock absorbing material to protect against breakage. Bottles shall be protected from falling or tipping with a Speedi-Dry or similar means.
2. Wheeled carts used to transport chemicals shall be stable and move smoothly over uneven surfaces without tipping or stopping suddenly, and shall have lipped surfaces that would contain the chemicals if the containers break.
3. Laboratory employees transporting hazardous chemicals must wear splash goggles and a lab coat or apron in case containers break or chemicals are splashed.
4. Use freight elevators when available. Passenger elevators shall be used only during low-use time periods and then shall be occupied only by those who are handling the chemicals. All hazardous chemicals shall be placed in a secondary container or acid carrying bucket with tight fitting covers and shock absorbing material to protect against breakage.
5. Compressed gas cylinders (see Appendix K) shall be transported with hand trucks only with the cylinder strapped in place. Cylinders shall NEVER be dragged. Keep the cylinder capped until use.
12
C. Stockrooms/Prep rooms
Stockrooms and prep rooms are areas in facilities in which relatively large quantities of chemicals are stored for laboratory use. The following rules will be followed for all stockrooms and prep rooms:
1. Access must be strictly limited to authorized Laboratory Employees. All prep rooms, and storeroom/stockrooms must be locked and secured when designated Laboratory Employees are not present.
2. The College through the CHO shall ensure that all stockrooms, prep rooms and other chemical storage areas are supplied with a mechanical exhaust ventilation system that provides at least six air changes per hour. Additional local exhaust (such as opening a window or bringing in a fan) may be required if activities such as dispensing take place in the storage area.
3. Each chemical stockroom and prep room must have access, in or adjacent to the room, to at least one large sink, safety shower, eyewash station, and appropriate fire extinguisher with adequate extinguishing capacity. The fire extinguisher shall be located next to the exit door and also within 25 feet of a hazardous area. Fire extinguishers, safety showers and eyewash stations cannot be obstructed.
4. For new facilities constructed subsequent to the implementation of this CHP, each stockroom and prep room and chemical storage area must have a master control shutoff valve for water, electricity, and gas.
5. Shelving must be secure and well balanced. Shelving characteristics shall include:
Anti-roll lips on all shelves to prevent containers from falling off shelves. Existing shelving otherwise suitable for storage shall not be replaced. New shelving shall have anti-roll lips.
Metal shelves shall be corrosion-resistant.
Aisles at least 3 feet between standing shelves.
Chemicals shall be stored according to the storage patterns described in Appendix E.
6. All stockroom and prep room exits must be clearly marked and unobstructed.
7. Stockrooms and prep rooms must be well lit so that labels can be easily read.
8. No aisle is permitted to dead end. Aisles must be kept clear of clutter. Material cannot be stored in a means of egress.
13
9. The environment in stockrooms must be controlled and avoid extremes of temperature and high humidity.
10. Floors must be kept clean and dry. If being cleaned or when a spill has occurred, signs shall be posted to warn of hazard.
D. Laboratory and other storage outside stock rooms and prep rooms
The nature of laboratory work calls for certain amounts of chemicals to be on hand for easy access. However, Designated Users and Technicians shall limit, as much as possible, the amount of chemicals stored on bench tops, in hoods or other exposed areas. (Information about chemical compatibilities is available in Appendix E.) When these chemicals are flammable, combustible, reactive, toxic, or corrosive, the following rules will be observed:
(1) Flammables and Combustibles
The ESO will determine the limits on the amounts of flammables, combustibles, reactives, and unstable chemicals in the laboratories based on applicable codes, which limits will be observed for each laboratory.
a. Flammable Liquids Storage Cabinets
Flammable materials must be stored in cabinets that meet OSHA and National Fire Protection Association (NFPA) specifications that cabinet contents be protected from temperatures exceeding 325 degrees F for at least 10 minutes, enough time for personnel to evacuate the area. See Appendix P for list of applicable OSHA and NFPA regulations.
Quantities of flammables stored shall not exceed the specifications for the cabinet posted inside the cabinet door.
b. Maximum Container Sizes
The NFPA limits on the size of the container for classes of flammable and combustible materials are listed in Appendix F. All original-manufacturer containers meet NFPA standards. Only NFPA-certified containers will be used for storage of flammable and combustible liquids. NFPA-certified containers are labeled as such, with the NFPA stamp.
c. Safety Cans for Flammables
NFPA-approved portable safety containers shall be used for storing flammable liquids. Flammable liquids in quantities greater that 4 liters (> 1 gallon) will be stored in metal containers. Flammable liquids purchased in large containers (> 1 gallon) shall be poured into smaller cans for distribution. The cans must be grounded and bonded during transfer of the liquid. The use of unapproved plastic containers is prohibited.
14
d. Flammable and Other Compressed Gases
The names of compressed gases must be prominently posted on the tank in which they are stored.
Flammable gas cylinders shall be stored in a separate area from other types of compressed gases.
If gases are manifolded or piped to or from equipment, the connections piping and/or tubing shall be compatible with the gases used (e.g. copper and acetylene are incompatible).
Cylinders must be grouped by the type of gas (e.g. toxic, corrosive, etc.). Cylinders of incompatible gases must be segregated by a minimum distance of 20 feet or by a noncombustible barrier at least 5 feet high having a fire rating of at least one-half hour.
Empty cylinders shall be separated from nonempty cylinders and labeled: “empty”.
All compressed gases must be stored away from direct or localized heat (including radiators, steam pipes, or boilers) in well-ventilated and dry areas and away from areas where heavy items may strike them (e.g. near elevators or service corridors).
All compressed gases, including empty cylinders, must be secured in a upright position with chains, straps, or special stands of adequate strength and must be capped when stored or moved.
A hand truck must be available for transporting gas cylinders to and from storage areas.
(Refer to Appendix K for additional information on Gas Cylinder Safety.)
(2) Oxidizers
a. Oxidizers must be stored away from incompatible materials such as:
(1) Flammables and combustible materials (Note: Chemical resistant trays may be used if chemicals are stored on wooden shelves.)
(2) Greases(3) Paper trash bins(4) Finely divided metals(5) Organic liquids(6) Other oxidizers
15
b. Nitric acid, sulfuric acid, and perchloric acid shall be stored separately from organic acids, from each other, and shall be in break-resistant containers and placed in acidic-resistant trays.
c. Strong oxidizing agents shall be stored and used in glass or other inert containers. Corks and rubber stoppers shall not be used.
(3) Peroxides
Peroxides and chemicals that tend to form peroxides must be stored in airtight containers in a dark, cool and dry place. Refer to Appendix J for a list of peroxide forming compounds and how to manage and assess their hazards. To minimize the rate of decomposition, peroxides and peroxidizable materials shall be stored at the lowest possible temperature consistent with their solubility and freezing point. Liquid peroxide or solutions shall not be stored at or below the temperature at which the peroxide freezes or precipitates, because peroxides in these forms are extremely sensitive to shock and heat.
(4) Toxic Chemicals
a. Extremely toxic substances must be stored in unbreakable chemically resistant secondary containers.
b. Adequate ventilation must be provided in storage areas especially for toxic chemicals that have a high vapor pressure.
c. All dispensing of these materials must be conducted in a fume hood.
3. Protective Apparel and Equipment
A. General
(1) After engineering and administrative controls have been put into place as per Appendix B, the potential for exposure to hazardous materials should be analyzed as part of SOP development. If any risk of exposure remains, Personal Protective Equipment (PPE) should be used to reduce that risk to a minimum.
(2) PPE includes, but is not limited to protective eyewear, gloves, respirators, and clothing.
(3) PPE must be evaluated by the CHO for chemical compatibility and suitability for use with the potential hazards. The CHO will provide instructions as to compatibility and suitability.
(4) Users must be trained by the CHO in the proper use of PPE. If respiratory protection is required, medical clearance and fit testing are also required.
(5) Laboratory SOPs including those for all laboratory experiments must include specific information on the type of PPE required for each
16
hazardous chemical or process. See CHP Section 1b and Appendix N for more information on SOPs.

over primary eye protection (spectacles or goggles).
Special purpose goggles. Ventilation shall be adequate, but
well protected from eye splash entry. Eye and face protection shall be designed and used so that it provides both adequate indirect ventilation and protects the wearer from splash entry (per ANSI Z87-1.1989).
Dust, glare, impact, foreign objects, work with UV light
● Irritation● Impact injury● Exposure to
UV light
● Impact goggles that meet ANSI Z87- 1.1989.
Gloves are often relied upon to prevent cuts, abrasions, burns, and skin contact with chemicals that are capable of causing local or systemic effects following dermal
18
exposure. There are no gloves available that provide protection against all potential hand hazards, and commonly available glove materials provide only limited protection against many chemicals. Therefore, it is important to select the most appropriate glove for a particular application and to determine how long it can be worn, and whether it can be reused. Hypoallergenic gloves must be provided if necessary.
The following chart can be used as a guide in determining the correct chemical protective clothing material for the chemical hazard. For the best protection, check with the manufacturer for degradation and permeation information.

Employees shall notify personnel trained in hazardous materials handling (all laboratory workers) and reportable spill clean up (lab technicians, CHO and ESO), who are trained to evaluate the spill quantity and location for feasibility of complete remediation. Such personnel must make a determination as to the type of spill (Incidental or Reportable), who may clean it, the appropriate protective apparel and equipment and proper disposal.
The College will maintain records of all spills of hazardous chemicals regardless of the category. An incident report must be filed with the CHO for any spill of hazardous chemicals. The CHO will keep the records of spills (as well as accidents). For Reportable Chemical Spills, the CHO will be responsible for reporting the spill to the appropriate authorities as warranted by state or local regulations.
Students are not allowed to perform spill clean ups.
A. Incidental Chemical Spills
Incidental spills are defined as hazardous chemical releases into a room which are less than 100 milliliters (mL) wet or 100 cubic centimeters (cc) dry.
(1) Incidental Chemical Spill Clean-up
Employees trained in hazardous materials handling and spill clean up shall evaluate the spill quantity and location for feasibility of complete remediation. Students are not allowed to perform spill clean ups. A Designated User must make a determination as to the type of spill (Incidental or Reportable), who may clean it, the appropriate protective apparel and equipment and proper disposal.
a. If any person has been contaminated by the spill, especially eyes and skin, you must:
Notify all other personnel in the affected room to evacuate, exit the room and close the doors to the room.
Assist the contaminated person(s) to a safe eyewash or drench station to wash the contamination away.
Notify the FSC Campus Police. Give the name of the chemical and state that a small spill has occurred. The FSC Campus Police will notify the ECO.

Remain at the door of the room to explain to the first responders the quantity and location of the spill.
22
b. If no person has been contaminated by the spill and the spill is localized, do the following:
Notify all other personnel in the affected room to evacuate including yourself. Have someone notify the Designated Laboratory User or Principle Investigator. Keep other people out of the laboratory. Do not re-enter the laboratory alone. Upon re-entry, use PPE such as gloves, eye protection, and body protection (e.g. lab coat).
Determine if the spill can be cleaned up using spill pillows, towels, universal sorbant, etc.
Clean up the spill using the materials found in spill kit (located in a 5-gallon bucket labeled SPILL KIT in each laboratory and Prep room as per Appendix B) and place the spill clean up items into a labeled hazardous waste container or the 5-gallon bucket and place it in the Satellite Accumulation Area.
Remove any contaminated PPE and immediately wash hands. Dispose of the contaminated PPE in the same manner as any contaminated item used in the spill clean up.
Report the incident to the ESO on Form 1 Incident Report in Appendix O, by the person responsible for the room or laboratory.
(2) Spill Remediation
FSC employees shall treat the spill in accordance with the training conducted as per Section 9 of this CHP. The incident shall be reported to the ESO on the Form 1 Incident Report by the person responsible for the room or laboratory and the first responders.
All items used in the spill cleanup shall be placed into a suitable container and labeled with the appropriate hazardous waste information. The container shall be placed into the Satellite Accumulation Area and handled in accordance with the procedures for handling waste as described in CHP Section 10.
B. Reportable Chemical Spills
Reportable spills are defined as hazardous chemical releases into a room which equal or exceed the Reportable Quantity per 310 CMR 40.1600 Massachusetts Oil and Hazardous Material List for a specific hazardous material. Spills which are greater than 100 milliliters (mL) wet or 100 cubic centimeters (cc) dry should be considered reportable spills.
23
(1) Reportable Chemical Spill Clean-up
Employees shall take the following actions:
Notify all other personnel in the affected room.
Direct all personnel to exit the room and close the doors to the room.
Prevent others from entering the room.
Notify the FSC Campus Police Department that a large spill has occurred. Tell the Campus Police the name of the chemical spilled. The Campus Police will notify the CHO and ESO.
The ESO shall notify the appropriate authority of the spill.
Remain at the door of the room to explain to the emergency response personnel the quantity and location of the spill.
Report the incident to the ESO on Form 1 Incident Report in Appendix O, by the person responsible for the room or laboratory.
(2) Spill Remediation
Trained FSC employees shall treat the spill in accordance with the procedures outlined in Section 9 of this CHP. The incident shall be reported to the ESO on the Form 1 Incident Report by the person responsible for the room or laboratory and the first responders. Students are not allowed to perform spill clean ups.
All items used in the spill cleanup shall be placed into a suitable container (e.g. spill kit pail) and labeled with the appropriate hazardous waste information. The container shall be placed into the Satellite Accumulation Area and handled in accordance with the procedures for handling waste as described in CHP Section 10.
(3) Reporting
The ESO will be responsible for making the appropriate notification of reportable hazardous material spills per 310 CMR 40.1600 Massachusetts Oil and Hazardous Material List.
C. Mixed Spills
A mixed spill involves biological material and chemical reagents.
(1) Individual Contamination:
If the skin becomes contaminated with blood or other potentially infectious material, wash the area thoroughly with soap and water.
24
If blood or other potentially infectious material is splashed into the eyes, immediately use the eyewash station, and flush for at least 15 minutes.
Remove grossly contaminated clothing immediately. Place the contaminated clothing in a plastic bag. Bag must be labeled with the appropriate hazard identification (i.e. Biohazard).
Report the spill to the Department Chair, and seek medical attention.
(2) Clean-up
a. General
Wear the appropriate PPE to clean up the spill. At a minimum, this includes gloves, protective eyewear and a mask, or face shield. Depending on the size and type of spill, impervious gowns, protective foot coverings, or respirators may be needed.
Pick up any broken glass with tongs, dust pan, or some other mechanical device. Do not use your hands.
Place absorbent towels over the spill, making sure not to spread the liquid.
Carefully pour a dilute bleach solution (1:10) or other EPA registered tuberculocidal agent over the absorbent towels. Let this remain for 20 minutes in order to disinfect the spill. Ensure that the chemical reagents spilled are compatible with bleach or the disinfectant. If the chemicals are not compatible with bleach or the disinfectant, skip the disinfectant step.
Carefully pick up the absorbent towels, and place in a plastic bag. Wash the contaminated area again with bleach, unless incompatible with spilled material, or other disinfectant. Rinse the area with water.
If the chemicals are incompatible with bleach or the disinfectant, after rinsing with water let the area dry completely, then wash the spill site with the dilute bleach solution or disinfectant.
All PPE, towels, and other items that became contaminated must be disposed of as Biohazard Waste as described in CHP Section 10.
Wash hands and any other exposed skin with soap and water before leaving the work area.
b. Spills or Breakage in a Centrifuge
Turn off the centrifuge, and allow it to come to a full stop before opening the cover.
Wear the appropriate PPE to clean the spill.
25
Remove any broken glass with tongs, dustpan, or other mechanical means, and clean the spill as outlined above.
c. Spills in a Chemical Fume Hood
Do not shut off the ventilation. The hood shall be left running to prevent the escape of contaminates. If there is a UV light, leave it on.
Wear the appropriate PPE. If the material is infectious, a respirator may be needed. Contact the ESO/CHO for additional information.
Use a diluted bleach solution (1:10) or an EPA registered tuberculocidal agent to disinfect the cabinet. Wipe the walls, work surfaces, and equipment with the disinfectant. Use sufficient amount of the disinfectant to ensure that he drain pans and catch basins below the work surface get disinfected. Lift the front exhaust grill and try to wipe all surfaces. Let the disinfectant stand for 10 minutes. Wipe the catch basin and drain the disinfectant into a container. Wipe the area with water.
This procedure will not disinfect the filters, blowers air duct, or other interior parts of the hood. Determine if the hood is to be sterilized, and if so, contact the ESO/CHO for additional information.
D. General/Emergencies
For emergencies such as fires, explosions, spills or transportation accidents, the protocol is: rescue anyone immediately affected by the emergencies only if it does not put you at risk, and then follow the instructions below. If trained, provide first aid to the victims:
(1) Notify the proper authorities:
If the emergency involves a fire, use the manual pull box to activate the alarm.
For other emergencies, contact FSC Campus Police and describe the emergency. Request the Police to contact the ESO for hazardous, biological, and chemical emergencies, and the Radiation Protection Officer if radiological materials are involved.
(2) Warn others in the area about the emergency, and stay clear of the area.
(3) Follow the directions of the emergency responders (i.e. Fire Department personnel, ESO or CHO). Do not reenter the area until area is deemed safe by the ESO, CHO or other emergency responders.
(4) Laboratory SOPs must include information on preventing and responding to spills for each hazardous chemical or process. See Appendix N.
26
7. Environmental Monitoring
Regular instrumental monitoring of airborne concentrations is not usually justified or practical in laboratories but may be appropriate when testing or redesigning hoods or other ventilation devices or when a highly toxic substance is stored or used regularly (e.g., 3 times/week). If necessary environmental monitoring will be carried out by a certified industrial hygienist.
8. Medical Program
A. Exposure Monitoring and Evaluation
(1) Exposure Monitoring
a. Monitoring for airborne concentrations of hazardous materials is not normally needed. OSHA regulated chemicals (e.g. formaldehyde, benzene, methylene chloride, and cadmium) are not normally used at FSC. The CHO must be contacted regarding monitoring if regulated chemicals are being considered for use.
b. Exposure monitoring for non-OSHA regulated chemicals will be conducted under the following circumstances:
When large quantities of a hazardous chemical are used for a long period of time as determined by the CHO.
When the Designated User requests monitoring. Requests for monitoring shall be made to the CHO who will make appropriate recommendations.
An accident involving release of air contaminants.
c. Within 15 days of monitoring, Designated Users will be notified of the results in writing either individually or by posting results in an appropriate location.
d. SOPs must state whether or not exposure monitoring is required for each hazardous chemical or process.
(2) Exposure Evaluation
a. An exposure evaluation is performed by a certified industrial hygienist (CIH) called in by the ESO to determine when any individual has suffered an exposure that might have harmed him or her. The purpose of an exposure evaluation is to identify the hazardous chemical, or chemicals, that were involved and the equipment and procedures relevant to the event. The evaluation will be presented to the ESO and Human Resources.
27
b. Events or circumstances which might reasonably be considered as evidence that an overexposure to hazardous chemicals has occurred include:
Uncontrolled release of a hazardous chemical.
Any monitoring or air sampling results indicating an exposure above acceptable levels.
Direct skin or eye contact with a hazardous chemical.
Detection of an odor, especially if the person was working with any hazardous chemical which has a lower permissible exposure limit (PEL) or threshold limit value (TLV) than its odor threshold.
The manifestation of health hazard symptoms.
The disappearance or diminishment of some or all symptoms when the person is taken away from the chemical area and into fresh air.
Reappearance of prior symptoms soon after the person resumes working with chemicals again.
Complaints from person(s) in the same work area.
c. The following procedure will be followed for an exposure evaluation:
i Interview the person reporting the event, and any other persons potentially exposed.
ii List essential information about the circumstances of the event, including:
Specific chemical(s) involved. Other chemicals used by workers involved in the
event. Other chemicals used by others in the immediate
area. Other chemicals stored in that area. Symptoms exhibited or described by workers. Symptoms stated in the MSDS or other pertinent
references for chemicals in the area. Description of control measures, such as fume
hoods and Personal Protective Equipment (PPE), and the way they were used at the time of the event.
28
Results of any air sampling as appropriate in the area.
iii Sample air and work surfaces as appropriate in the area.
iv Determine how the worker’s symptoms compare to the information in the literature.
v Decide whether to send the worker for preliminary medical evaluations.
vi Review the adequacies of present control measures and safety procedures.
B. Medical Consults and Exams
(1) General Requirements
a. Employees of the College and students who work with hazardous chemicals are provided the opportunity to receive a medical consultation and examination whenever:
an employee or student develops signs and symptoms of exposure associated with any chemicals they are using, or may be in contact with, in the laboratory.
substances are measured above PELs.
an event takes place in the work area such as a spill or leak which is likely to result in a hazardous exposure.
b. All medical examinations and consultations must:
be performed under the direct supervision of a licensed occupational physician. Every effort shall be made to refer employees and students to licensed physicians who have been trained to recognize signs and symptoms of chemical related exposure and disease.
be provided by FSC at no cost.
be provided without loss of pay to the employee.
be performed at a reasonable time and place for the employee or student. Every effort shall be made to schedule medical examinations and consultations during the employee’s regularly scheduled work hours, provided there is no undue delay in medical attention.
29
c. The College must provide to the examining physician:
the generic and trade names of all hazardous chemicals and chemical compounds to which the employee or student may have been exposed. The College shall also provide to the physician copies of MSDSs for any suspect chemicals.
conditions under which the exposure occurred. The College must provide all available information including data pertaining to experiments or procedures involved.
A description of the signs or symptoms of exposure experienced by the employee or student during, immediately after, and within 72 hours after the incident. Everyone in proximity to the exposure shall be interviewed by the Certified Industrial Hygienist, CIH to determine if others experienced similar symptoms. In the event that the employee or student is not able to communicate, others in the laboratory may be able to recall symptoms that they observed or to discuss the employee’s or student’s complaints.
(2) Human Resources Requirements
a. Human Resources must obtain a written opinion from the examining physician. The written opinion must include:
recommendations for medical follow-up.
the results of all medical examinations and tests.
any medical condition that the employee or student has that places him or her at risk as a result of future exposures to hazardous chemicals.
a statement confirming that the employee or student has been advised of the results of the examination and tests, including any medical conditions relevant to occupational or chemical exposures.
b. Employee medical records will be kept by the Human Resources Department at FSC for 30 years. Student medical records will be kept on file in the Environmental Health & Safety Office. Medical records are considered privileged information.
30
9. Information and Training Program
A. Information
Each Department must make health and safety information for each chemical (or hazard class or chemicals) used or stored in the lab readily available to all laboratory employees and students during working hours. Employees and students must have access to MSDSs and other reference texts on chemical health hazards, fire hazards, reactivity hazards, and properties (vapor density, vapor pressure, lower and upper explosive limits, etc…) at any time. Employees and students must have access to a copy of this CHP, the OSHA Laboratory Standard and its appendices, as well as to a list of OSHA permissible exposure limits. These documents are available in each Laboratory in the Right-to-Know binder, and/or in the ESO's office.
B. Annual Training
(1) Personnel Affected
All laboratory employees, including faculty, student employees, secretaries, laboratory technicians, and maintenance and custodial employees who may come in contact with the laboratory environment must attend a laboratory employee training session provided by the ESO within 30 days of initial employment and each year thereafter. The training will cover rights and responsibilities under the OSHA Laboratory Standard, the Massachusetts Right-To-Know Law and specific operating procedures for working with chemicals. Additional training will be provided when new hazards are introduced.
(2) Training Program Elements
A department-specific chemical hazard orientation session will be provided annually for each department by the ESO. Specific focus for training sessions will be developed by the ESO in conjunction with departmental representatives.
All laboratory employees must attend these sessions at least once a year. Training must be given in languages that can be understood by all employees. The ESO will coordinate attendance through designated department personnel. These orientation sessions will cover the following topics:
i. Commonwealth of Massachusetts Right-to-Know Law provisions.
ii. Contents of the OSHA Laboratory Standard and its appendices.
iii. Location and availability of the Chemical Hygiene Plan, Material Safety Data Sheets, and additional resources on all aspects of laboratory health and safety relevant to employee exposure.
iv. How to read a Material Data Safety Sheet.
31
v. Physical and health hazards of chemical classes (flammable, carcinogens, corrosives, etc…) used by employees and general operation procedures for handling, storing, and disposing of these materials.
vi. Signs and symptoms of exposure to chemicals and availability of medical consultations and exams.
vii. Use of fume hoods and personal protective equipment.
viii. Special operating procedures to be used for extremely hazardous chemicals.
ix. How to conduct a hazard evaluation of lab operations.
x. How to conduct a laboratory inspection.

xiii. Emergency procedures
xiv. Filing incident report forms.
C. Hands-on Instruction
All Designated Users will conduct training of students or workers under their supervision with assistance from the ESO or other capable individuals to ensure that all individuals in the laboratory receive hand-on experience with:
1. Proper use of fume hoods and other exhaust system and assessment of hood performance.
2. Use of emergency showers and eyewash stations.
3. Location and use of spill-control equipment.
4. Emergency protocol and telephone numbers.
5. Chemicals and standard operating procedures used in the laboratory.
6. When feasible, spill scenarios (derived from selected hazard evaluations of procedures conducted in the laboratory) and potential medical emergencies will be simulated (using inert materials) and discussed.
32
D. Refresher and New Hazard Training
Training for experienced workers will be scheduled whenever new hazards are introduced, and when lab conditions or practices change. Refresher training will be scheduled or integrated into other lab activities as needed. Training will be coordinated by the ESO.
E. Training Materials
The following materials, at a minimum, will be distributed in each initial training program:
1. Right-to-Know fact sheet2. Laboratory standard fact sheet3. List of key emergency telephone numbers4. Sample MSDS and fact sheet on how to read chemical storage scheme chart.5. List of hazard classes and chemical examples6. Hazard review checklist7. Laboratory inspection form/checklist8. Incident report form
F. Training Records
ESO will maintain initial and annual employee training records. Each department must maintain records of all laboratory in-service training sessions, including sample agendas, handouts, sign-in sheets, course data, and the number of hours participants attended. Copies of these records must be provided to the ESO after each training session. The ESO will maintain a complete file of all training records. Records will be maintained for three (3) years. Additionally, copies of training records will also be sent to Human Resources and maintained in each individual employee file.
10. Waste Disposal Program
Wastes generated in the laboratory are divided into four major categories: general (non-hazardous) waste, chemical waste, universal waste and hazardous waste. General waste may be disposed of in the regular trash, chemical waste is a chemical waste material for which no hazard classification has been made, and hazardous waste must be collected, labeled and handled following the RCRA regulations. When a determination is made that a waste material belongs to a specific hazard class then it will be designated as either a “Hazardous Waste” or a “Universal Waste” or General Waste” as appropriate.
A. General Work Practices
To assure that minimal harm to people, other organisms, and the environment will result from the disposal of waste laboratory chemicals, laboratory standard operating procedures must include information on waste disposal for all chemicals or processes. Contact the CHO for more specific guidance. SOPs should be designed to minimize the generation of hazardous waste. The following work practices shall be followed.
33
1. Provide a copy of the laboratory experiment or the chemicals and waste stream analysis for each laboratory experiment to the lab technicians who will determine whether or not the chemical waste is hazardous waste and will provide the proper packaging and hazardous waste labeling.
2. All chemical waste generated in laboratories must be collected for proper characterization and disposal. Disposal by pouring waste chemicals that are determined to be hazardous down the drain or adding them to mixed refuse for landfill burial is prohibited.
3. Hoods should not be used as a means of disposal for volatile chemicals.
4. When packaging any type of waste for collection do not put more than 40 pounds of waste in a single container nor fill it more than 3/4 full. Allow space in containers for expansion of vapors.
5. All materials that pose a potential puncture hazard (e.g. hypodermic needles, broken glass, and plastic-ware) must be packaged in puncture resistant containers prior to removal from the work area.
6. Do not mix general waste with hazardous wastes (e.g. biohazard wastes, asbestos, chemical or radioactive waste). Do not commingle hazardous waste categories (e.g. flammables and poisons). Do not package general waste in hazardous waste containers.
7. Non-water soluble materials, primary radioactive wastes, and hazardous chemical wastes such as corrosives, flammable liquids, carcinogens, mutagens, and other toxic or reactive chemicals shall not be discharged into any sanitary or storm drain systems.
8. Do not “stage” wastes. Wastes must ever be left for any reason in or on loading docks, elevators, lobbies, hallways, or any other unrestricted locations.
9. All hazardous wastes must be identified and labeled before being offered for disposal. Waste of unknown or incorrectly described composition presents difficult handling and disposal problems and may require costly analysis before removal and disposal can be accomplished.
10. Before initiating treatment or recycling of a hazardous waste, generators are requested to contact the CHO to ensure that the proposed treatment process meets safety, regulatory, and record keeping requirements.
B. Procedures for Handling Chemical Waste and Hazardous Waste
A “CHEMICAL WASTE” is generally a waste from a laboratory experiment that has not been identified as a “HAZARDOUS WASTE”. If you are not sure whether or not a waste is a hazardous waste, label it as “CHEMICAL WASTE”.
34
No chemicals or hazardous wastes are to be discarded into sink drains. Discard all waste chemicals into properly labeled chemical waste/hazardous waste
containers. Do not fill waste containers to the top. Clearly identify the contents of the waste or mixture. (Chemical formulas and
structural diagrams are not legally acceptable and must not be used.) Containers must be closed at all times except when waste is being added or
removed. Cap waste containers tightly, especially if any volatile organic chemicals are
present. All hazardous wastes must be segregated according to chemical compatibility.
Incompatible wastes should never be mixed or placed next to each other, see Appendix E, Chemical Compatibility Chart and Storage Systems.
Containers must be in good condition and compatible with the chemical contents. Notify the CHO that the waste is ready to be collected. Laboratory chemical waste
containers must be removed after each experiment to avoid potential contamination with wastes from other experiments.
C. Procedures for Handling Universal Waste
Hazardous wastes that qualify under the federal Universal Waste Rule are managed according to the Massachusetts Standards for Universal Waste Management 310 CMR 30.1000. Universal wastes include certain batteries such as nickel cadmium (NiCd) and silver batteries; thermostats containing mercury; mercury containing devices such as
manometers, switches, water meters, thermometers, and gauges; mercury containing lamps including spent fluorescent lamps and high intensity discharge lamps; and pesticides including mercury based pesticides, arsenic based pesticides, chlorinated pesticides, and banned or suspended pesticides. If you are not sure whether an item is a
universal waste, you should consult the CHO. Universal wastes are stored in a separate area marked as a "Universal Waste Accumulation Area". See Appendix P for the FSC Universal Waste Management Plan.
D. Labeling Waste Containers
To avoid confusion and to reduce risk to yourself and others in your workplace, all waste containers, regardless of size, must be labeled with the name of the substance (chemical formulas and structural diagrams are not legally acceptable).
Label waste containers clearly and completely according to the appropriate waste: “CHEMICAL WASTE”, “HAZARDOUS WASTE”, or “UNIVERSAL WASTE”.
Clearly identify the hazardous constituents contained therein (e.g., methanol, toluene, acetone) and the hazards posed (e.g., corrosive, ignitable, toxic, and/or reactive);
The label should state “HANDLE WITH CARE.”
35
The label should also include all of the following that may apply: course, experiment, professor, and room number. Printed labels are available from the CHO.
If you find an unlabeled container and are unsure of its contents, notify the CHO.
E. Removal of Hazardous Waste Containers
The date must be entered on the label of the waste container at the satellite point (satellite accumulation area) when the container becomes full. Satellite accumulation areas (SAA) for hazardous waste are located in each laboratory. See Appendix P for SAA locations list.
Designated users must notify the laboratory technicians that the waste is ready to be collected. Waste containers must be removed from the laboratory after each experiment to avoid potential contamination with wastes from other experiments.
The waste container must be removed from the satellite point to the hazardous waste accumulation area within three (3) days of the time the container is dated (i.e. when the container is full or the lab procedure is complete). Removal of dated hazardous waste containers is managed by the CHO.
A copy of the laboratory experiment or the chemicals that went into the waste for each laboratory experiment must be provided to the ESO/CHO. The ESO/CHO will determine whether or not the chemical waste is a hazardous waste and will provide the proper packaging and additional hazardous waste labeling.
11. Records
A. Accident records should be prepared on Form 1 Incident Report in Appendix O, by the person responsible for the room or laboratory and submitted to the ESO.

I. Managing and Assessing the Hazards of Peroxide Forming Chemicals
The FSC Environmental Safety Office, with help from the University of Washington Department of Environmental Health and Safety, has developed the following guidelines for identifying the presence of dangerous, explosive peroxides in some laboratory substances. Faculty, staff, and students may evaluate the concentration of peroxides in substances by following the following guidelines. AT NO TIME are students to apply the guidelines set forth in this document when the peroxide forming substance has past the manufactures expiration date.
II. Background
Peroxides formed in organic compounds by auto-oxidation can cause serious accidents. In somecircumstances, peroxides become low power explosives. They are also hazardous by being sensitive to shock, sparks, or other forms of accidental ignition. The appropriate actions taken to prevent injuries from peroxide forming compounds depend on understanding the factors causing peroxide formation, detection, and adequate labeling and inventory procedures. The Environmental Safety Office (ESO) can provide FSC faculty and staff with more information on detecting and reducing peroxides upon request. When appropriate, the ESO will arrange to have a contractor measure the peroxide concentration and reduce the formed peroxides if necessary.
To prevent peroxide formation in laboratory substances:
A. Peroxidizable compounds must be exposed to oxygen in order to form appreciable amounts of peroxide. As a result, tightly sealed, unopened containers of material, which have either been stabilized or stored under inert gas, will not form dangerous concentrations of peroxides.
B. Exposure to light accelerates peroxide formation. Airtight amber glass containers arerecommended for the storage of peroxidizable compounds. The amber glass container protects the substance from excess light exposure and allows the user visual access to the substance without opening the container.
Peroxidized compounds can pose an explosion hazard under two situations:
1. When complex peroxides form a solid or precipitate in a peroxidizable liquid or,
2. When a peroxidizable liquid is concentrated (by distillation, evaporation, etc.), leaving high concentrations of dissolved peroxides.
III. Common Peroxide-Forming Chemicals
A number of compounds, especially ethers, sodium and potassium amide, and potassium metal can form peroxides and superoxides that pose an explosion hazard. Below is a list of substances that upon exposure to air and light should be tested for the presence of peroxides before being used. THE RECOMMENDED RETENTION TIME BEGINS WITH THE DATE OF SYNTHESIS OR OPENING. Peroxides will form at varying rates depending on the substance,
70
the length of exposure to air and light, and the container type. For example, the storage time required for peroxides to increase from 0.5 ppm to 5 ppm was 6 months in an aluminum container, and over 17 months in a glass container. Peroxides may form in freshly distilled and unstabilized ethers within two weeks, and it has been reported that that peroxide formation can begin in tetrahydrofuran after three days and in ethyl ether after eight days. Peroxide forming substances that are to be distilled should be tested for peroxides prior to distillation.
The following list does not reflect all possible chemicals that pose a risk. Check the Material Safety Data Sheet (MSDS) of the substance before use to determine if the substance is at risk of forming explosive peroxides, or polymerizes rapidly. If a substance forms explosive peroxides or polymerizes rapidly, there will be warning under the heading Precautionary Labeling or Fire and Explosion Hazard Data on the MSDS. If a substance does not appear on the list, and the Material Safety Data Sheet does not disclose any hazards, evaluate the molecular structure and determine if the substance is a potential peroxide former.

Low Peroxide Hazard SubstancesDISCARD AFTER ONE YEAR OF OPENING
Compounds containing aldehyde or amide groups are easily peroxidizable but are not known to accumulate peroxide at dangerous levels.
IV. Common Chemical Families Known to be Peroxide Formers
ORGANICSA. Ethers, acetals.B. Olefins with allylic hydrogens, chloro- and fluoroolefins, terpenes, tetrahydronaphthalene.C. Dienes, vinyl acetylenes.D. Aldehydes.E. Ureas, amides, lactams.F. Vinyl monomers including vinyl halides, acrylates, methacrylates, vinyl esters.
INORGANICSA. Alkali metals, particularly potassium.B. Alkali metal alkoxides and amides.C. Organometallics.
It is important for laboratory personnel to recognize the readily peroxidizable families for safety reasons. The more volatile the compound, the greater the potential hazard, since evaporationconcentrates the formed peroxides.
V. Evaluating and Testing
The single most preferable approach to handling dangerous peroxidizable and polymerizable compounds is to eliminate the use of these type of laboratory substances. When elimination is not practical, process modification and material substitution should be evaluated to reduce the quantity of these substances used. Chemical users should establish rigorous procurement guidelines for control over purchasing. Try to purchase materials in containers sized to the amount needed. Purchase substances that have been stabilized. Encourage the sharing of chemicals or exchange chemicals between common users. Lastly, keep a running inventory of these substances in stock. After the substance is purchased, remember to record on each container the date purchased and the date of opening. Monitor the container volume for loss due to evaporation, and test for the presence of peroxides before each use. The absence or exhaustion of a stabilizer may not always be obvious. Peroxidizable solvents should always be regarded as containing peroxides. Always record the test data for the next user, and store the substance under an inert atmosphere when possible. Complete the evaluation questions for each peroxide forming chemical or rapid polymerizer that is to be discarded. If at some time during this
72
evaluation an item becomes unsuitable to handle, contact the ESO. Provide documentation of the evaluation and a history on the substance. Those substances failing the evaluation process will be disposed of by an outside hazardous materials specialist at the laboratory’s expense.
Step 1. Identify the material

Expiration date on thecontainer: ___________________________________________
Type and condition ofcontainer: ___________________________________________
Date of purchase on thecontainer: ___________________________________________
Date of last usage: ___________________________________________
Approximate containervolume: ___________________________________________
Step 2. Screen for visible crystalline materialLook to see if crystals have formed inside the container, either on the inner walls or bottom. If the container is metal, please go to Step 3.
WARNING: If a viscous liquid, or crystalline solids are observed, no further tests are recommended. These materials could be shock, friction, and impact sensitive and may cause a violent explosion. Contact the ESO immediately to schedule a contractor to stabilize the material.
Step 3. Determine the substance’s likelihood of forming dangerous peroxides
Step 4. Test for peroxidesPeroxidizable chemicals that are acceptable for testing should be tested by the ESO or his/her designee using either method A or method B, as appropriate. If the peroxide concentration exceeds 10 ppm, the substance must be reduced and stabilized prior to collection by the ESO. Professional handling will be required if the laboratory is not able to test and reduce the peroxide concentration to less than 10 ppm. Reactive Materials Specialists are contracted through the ESO. If the peroxide concentration is less than 10 ppm, proceed to step 5.Method A (Test Strip)
Where containers can be safely opened, a manufactured test strip can be used to detect peroxides.
73
Peroxide test strips detect inorganic and organic compounds that contain a peroxide or hyperperoxide group. Test strips are well suited for the routine control of simple ethers such as diethyl ether, tetrahydrofuran, and p-dioxane. Use EM Quantitative Peroxide Test, a colorimetric dipstick test developed by Merck. Carefully read the instructions provided by the manufacturer before performing the test.
Method B (Iodide Test)
Where the containers can be safely opened, check for peroxides by following the Physical Chemical Method for detecting peroxide concentrations cited by M.A. Armour. (See reference 6)To begin, wear chemical resistant gloves, a laboratory coat, and eye protection. This procedure must be performed in a certified fume hood. Dissolve 100 mg of potassium iodide in 1 mm of glacial acetic acid. Add the mixture to 1 mm of the substance being tested for peroxide concentration. A pale yellow color indicates a low concentration (0.001 – 0.005%). This may also be interpreted as a barely discernable yellow. A bright yellow or brown indicates a higher concentration (0.01% or greater) of peroxides in the sample. For testing resulting in concentrations 0.001% or above, discontinue any handling, secure the substance being evaluated and proceed to step 6. Substances 5 that have 0.01% or greater peroxide concentration can be very dangerous to handle. If the concentration of peroxides is less than 0.001%, proceed to step 5.
Step 5. Stabilization of peroxides
Stabiliztion of peroxides will be carried out by the ESO or his/her designee. To stabilize peroxide forming compounds add a minimum of 1 gram of butylated hydroxytoluene (BHT) per liter of substance. BHT is an antioxidant used to retard the oxidation process in peroxidizable compounds. This procedure will not reduce the peroxides already formed in the substance. Label the substance with the peroxide concentration and indicate that the substance was stabilized. Store the substance for additional use, or dispose of as hazardous waste, whichever is appropriate.
Step 6. Disposal through ESO
When in the evaluation process a point is reached when a chemical should not be tested further, complete the Information Requirements for Potentially Explosive Items form located at the end of this Appendix and deliver to the ESO. The substance(s) will be referred to a hazardous material specialist for deactivation. Deactivation entails identifying the concentration of peroxide, reducing any formed peroxides, and then stabilizing the substance. Deactivation costs will be recharged to the laboratory. While awaiting the hazardous materials specialist, protect the substance from excessive handling. If you have any questions regarding any part of this protocol, please contact the Environmental Safety Management at 978-665-3756.

Background Information
This document contains basic guidelines and rules to help ensure the safe handling and storage of compressed gas cylinders. Compressed gases are used in a variety of programs such as instructional and research laboratories, health sciences, fine arts. Compressed gases under high pressure also present a number of hazards. Mishandled cylinders may rupture violently, release their hazardous contents or become dangerous projectiles. If the neck of a pressurized cylinder should be accidentally broken off, the energy released would be sufficient to propel the cylinder to over three-quarters of a mile in height. A standard 250 cubic foot cylinder pressurized to 2,500 PSIG can become a rocket attaining a speed of over 30 miles per hour in a fraction of a second after venting from the broken cylinder connection.
Basic Safety
Select the least hazardous gases that will work. Purchase only the necessary quantities.
Select gases with returnable containers. When receiving gas cylinders: Check for leaks. Visually inspect the cylinder for damage. Ensure the valve cover and shipping cap is on. Check for proper labeling.
If a cylinder is damaged, in poor condition, leaking, or the contents are unknown, contact your cylinder vendor. Have the vendor return the damaged cylinder to the manufacturer.
Wear appropriate foot protection when engaged in moving or transporting cylinders. Sturdy shoes are a minimum.
Steel toed shoes if required by your supervisor, instructor, or department. Proper personal protective clothing and equipment shall be worn.
Always have an appropriate Material Safety Data Sheet (MSDS) available and be familiar with the health, flammability and reactivity hazards for the particular gas.
Cylinder Markings:
Cylinders must be properly labeled, including the gas identity and appropriate hazards (e.g., health, flammability, reactivity). Cylinders have several stamped markings. The top mark is either a DOT or an ICC marking indicating pertinent regulations for that cylinder. The second mark is the serial number. Under the serial number is the symbol of the manufacturer, user, or purchaser. Of the remaining marks the numbers represent the date of manufacture, and retest date (month and year). A (+) sign indicates the cylinder may be 10% overcharged, and a star indicates a ten year test interval.
Cylinder Storage
78
Gas cylinders will not be stored at the College for extended periods of time. When a tank becomes empty arrangements will be made by the laboratory technicians to have it removed. A single replacement tank may be kept at the site of use to ensure an adequate gas supply. If long term storage becomes necessary for a specific purpose, the Designated User shall notify the ESO and arrangements shall be made through the Environmental Safety Office to provide a storage location for that purpose.
Cylinders should be stored in compatible groups:Flammables from oxidizers
Corrosives from flammables Full cylinders from empties
Empty cylinders should be clearly marked and stored as carefully as those that are full because residual gas may be present.
o All cylinders from corrosive vapors. o Store cylinders in an upright position. o Keep oxygen cylinders a minimum of twenty feet from flammable gas
cylinders or combustible materials. If this cannot be done, separation by a non-combustible barrier at least five feet high having a fire-rating of at least one-half hour is required.
o Compressed gas cylinders should be secured firmly at all times. A clamp and belt or chain, securing the cylinder between "waist" and "shoulder" to a wall, are generally suitable for this purpose.
o Cylinders should be individually secured; using a single restraint strap around a number of cylinders is often not effective.
o Keep valve protective caps in place when the cylinder is not in use.
o Mark empty cylinders EMPTY or MT. o Keep valves closed on empty cylinders. o Cylinders must be kept away from sources of heat. o Cylinders must be kept away from electrical wiring where the cylinder
could become part of the circuit. o Store cylinders in well-ventilated areas designated and marked only for
cylinders.
Moving Cylinderso Use a cylinder cart and secure cylinders with a chain. o Don't use the protective valve caps for moving or lifting cylinders. o Don't drop a cylinder, or permit them to strike each other violently or be
handled roughly.
79
o Unless cylinders are secured on a special cart, regulators shall be removed, valves closed and protective valve caps in place before cylinders are moved.
Cylinder Use
o Be sure all connections are tight. Use soapy water to locate leaks. o Keep cylinders valves, regulators, couplings, hoses and apparatus clean
and free of oil and grease. o Keep cylinders away from open flames and sources of heat. o Safety devices and valves shall not be tampered with, nor repairs
attempted. o Use flashback arrestors and reverse-flow check valves to prevent
flashback when using oxy-fuel systems. o Regulators shall be removed when moving cylinders, when work is
completed, and when cylinders are empty. o Cylinders shall be used and stored in an upright position. o The cylinder valve should always be opened slowly. Always stand away
from the face and back of the gauge when opening the cylinder valve. o When a special wrench is required to open a cylinder or manifold valve,
the wrench shall be left in place on the valve stem when in use. This precaution is taken so the gas supply can be shut off quickly in case of an emergency. Nothing shall be placed on top of a cylinder that may damage the safety device or interfere with the quick closing of the valve.
o Fire extinguishing equipment should be readily available when combustible materials can be exposed to welding or cutting operations using compressed cylinder gases.
Things Not To Do
o Never roll a cylinder to move it. o Never carry a cylinder by the valve. o Never leave an open cylinder unattended. o Never leave a cylinder unsecured. o Never force improper attachments on to the wrong cylinder. o Never grease or oil the regulator, valve, or fittings of an oxygen cylinder. o Never refill a cylinder. o Never use a flame to locate gas leaks. o Never attempt to mix gases in a cylinder. o Never discard pressurized cylinders in the normal trash.
Poison Gases
Poison gases represent a significant hazard. Special precautions not otherwise necessary become prudent when using poison gases:
80
Common poison or highly toxic gases include:o arsine (AsH3)o ethylene oxide (EtO)o hydrogen cyanide (HCN)o nitric oxide (NO)o phosphine (PH3)
Certain poison gases (e.g., Ethylene Oxide) can only be used if specific OSHA regulations (CFR 1910.1047) and safe practices are followed.
Emergency procedures should be made clear to all involved, including personnel from adjacent labs and building managers. Poison gas use after normal working hours require the approval of the Department Chairperson. Fume hoods and other ventilation need to be tested before use and checked frequently during the project involving poison gas. Notify the Department Chairperson before your first use of the poison gas. As with all chemicals, obtain and review the Material Safety Data Sheet (MSDS) for the poison gas.
Disposal of poison gas cylinders can often cause problems. If the cylinder cannot be returned to the manufacturer large disposal costs will be incurred, ($1,000 per cylinder, or more). Even cylinders that can be returned must be shipped on a vehicle which cannot simultaneously carry any other hazardous materials or foodstuffs. Therefore, the use of poison gases is discouraged.

Fitchburg State CollegeChemical Ordering Policy
Before any new chemical purchases can be approved, a current chemical inventory must be submitted to the Environmental Safety Office.
This inventory must include:
ChemicalAmount in stock at beginning of semesterAmount remaining at end of semester
This system will help us purchase the adequate quantity of chemicals and minimize the hazards that occur from the storage of dangerous chemicals.
These records will be kept in the Environmental Safety Office, and used as a guide when reviewing chemical purchase orders for approval.
Questions or concerns should be directed to the Environmental Safety Officer at extension 3756.
105
PROCEDURE FOR WRITING STANDARD OPERATING PROCEDURES
Standard Operating Procedures (SOPs) are a set of written procedures explaining how to safely work with hazardous chemicals. Three methods can be used to categorize SOPs: by process (e.g. lab protocols), by individual hazard class (e.g. inorganic acids) or by hazardous chemical class (e.g. perchloric acid). The Standard Operating Procedure is a valuable tool and worth the preparation time. SOPs go beyond the basic "cookbook" procedural description of materials and methods and also provide details about the appropriate precautions. Here are some examples of topics that lend themselves well to the SOP format:
Inventory procedure for stock/reference cultures Laboratory security Disposal of hazardous materials, including sharps, chemicals and biological
materials Surface decontamination Spill procedure Operation and maintenance of equipment such as the centrifuge, Biological
Safety Cabinet , and autoclave Transportation of hazardous materials between facilities
In general, SOPs force a person to think through a procedure step by step and to standardize the materials and methods. The exercise of writing the SOP is valuable and the SOP itself is a useful training tool and a reminder to staff of the correct procedures. In some situations, SOPs may be required for compliance with regulations (e.g., Good Laboratory Practices, Food and Drug Administration, 40 CFR 160.81).
The best approach to writing an SOP is to do it, write it, and test it. Be brief and succinct, the shorter, the better. Anyone - student, support staff or principal investigator, can prepare them. The SOPs should be available in the laboratory, not filed away in an office drawer.
SOPs should be reviewed annually at a minimum.
Below is a template for a Standard Operating Procedures (SOP) that you may adapt for your own SOPs.

APPENDIX P: FITCHBURG STATE COLLEGE UNIVERSAL WASTE
MANAGEMENT PLAN
Universal Waste Management at Fitchburg State College
A comprehensive universal waste management program is in place at the college, that includes designated collection and accumulation areas in each of our buildings, annual universal waste management training for our building services staff and an inspection/audit program to ensure we are managing our universal waste in compliance with Federal and State regulations. FSC is classified as a Small Quantity Handler of universal wastes, accumulating less than 5,000 kilograms of universal waste at any time. Our operations generate mercury-containing lamps, various types of batteries, and any mercury-containing devices that we replace as part of our mercury-free device initiative. These wastes are classified as universal waste by Federal and Massachusetts regulations, 40 C.F.R. 273 and 310 C.M.R. 30.1000-30.1082 respectively. We partner with a state vendor, the Institutional Recycling Network to recycle our universal waste.
