Introduction:

In 1990, the Occupational Exposure to Hazardous Chemicals (OSHA) instituted “The Laboratory Standard”-‐Occupational Exposure to Hazardous Chemicals in Laboratories. This new “Laboratory Standard” has been designed to address the specific safety needs of the laboratory. The laboratory standard ensures that employees who work in a lab setting will be protected from any chemical exposure that exceeds permissible exposure limits and that employees will be educated as to the hazardous nature of the chemicals they use in the lab. To achieve this goal, the Laboratory Standard requires the school district to appoint a chemical hygiene office to develop, implement, and monitor a chemical hygiene plan. District Responsibilities:

1. Record all employee exposures to hazardous chemicals. a. Record all chemical exposures and use monitoring instruments to get

hard data. Obtain and keep up-‐to-‐date information provided by a medical examination resulting from a chemical exposure.

b. Keep these records and allow employees access to their personal records, including all employee exposure and medical records.

2. Train employees to: a. Understand the hazards of chemicals they use in the lab b. Recognize signs and symptoms associated with overexposure to

hazardous chemicals. c. Properly use personal protective equipment (Fume hoods, goggles,

respirators, etc.) d. Protect themselves from chemical exposure by following good lab

procedures. e. Understand the content of the Chemical Hygiene Plan.

3. Provide employees access to: a. MSDS (Materials Safety Data Sheets) for all hazardous materials. b. Previous exposure records (if any). c. The laboratory standard and chemical hygiene plan d. Permissible exposure limits of hazardous chemicals used in the lab e. Their own personal medical records (if any)

School Responsibilities: 1. Appoint a Chemical Hygiene officer. 2. Maintain and understand a Chemical Hygiene plan. 3. Upon receipt of chemicals:

a. Make sure you have the MSDS b. Make sure the label is proper and contains the minimum amount of

information. (chemical name, concentration, hazard information, name and address of manufacturer or name of preparer and date of preparation.

4. Maintain a current inventory of all chemicals.


5. Properly organize all lab chemicals. 6. Properly dispose of hazardous and nonhazardous chemicals.

2. Clean up spills immediately and thoroughly. 3. A bucket of dry sand should be available to aid in providing traction on a slippery

floor after a spill. 4. To make it easier to clean up, transport, and dispose, an absorbing agent, such as

kitty litter, should be used to absorb a liquid spill. 5. Neutralizer for both acid and base spills should be available in the event of a

chemical spill. 6. A 100% wool fire blanket will contain and control a spill and its vapors if no other

spill control materials are available. 7. Chemical Storage Rules and Procedures

1. Post emergency telephone numbers in the classroom/lab. 2. Keep an updated inventory of all chemicals, their amounts and locations.

Chemicals should be examined annually. 3. Establish a procedure to update the chemical inventory by updating the quantity

of each chemical as it is used and restocked. 4. Label all chemical solutions you make with the identity of the contents, date,

concentration, hazards information, and your name. 5. Label all chemicals with a purchase data. 6. Establish a separate, secure, and locked storage area for chemicals. 7. Do not allow incoming shipments of chemicals to be opened and transported by

school personnel other than qualified science teachers. 8. All chemicals should be stored in chemically compatible families. 9. Determine the maximum amount of a chemical needed for two-‐three years of

instruction and order and store only this amount. 10. Store corrosives in appropriate corrosive cabinets. 11. All flammable materials should be stored in an approved flammable storage

cabinet. 12. Do not store chemicals under the fume hood. 13. Avoid storing chemicals on shelves above eye level. 14. Shelves should be equipped with lips to prevent containers from rolling off. 15. Chemicals should not be stored on the floor except in approved shipping

containers. 16. The chemical storage area should be ventilated by at least four changes of air per

hour. 17. Store all poisons inside a locked cabinet.


18. Only authorize personnel are allowed in the chemical storage area. Students should NEVER be allowed in this area.

19. Avoid exposing chemicals to heat or direct sunlight. 8. Gas Handling Instructions

1. Compressed gases should be handled as high energy sources, and therefore, as potential explosives.

2. Always protect the cylinder valve stem. 3. Avoid exposure of cylinders to heat. Do not store gas cylinders in direct sunlight. 4. Never lubricate, modify, force or tamper with a cylinder valve. 5. Cylinders of toxic, flammable or reactive gases should be used only under a fume

hood. 6. Do not extinguish a flame involving a combustible gas until the gas is shut off—

otherwise it can reignite—possibly causing an explosion. 7. Gas cylinders must be secured in place. They must be protected to prevent valve

damage which may be caused by falling.

9. Flammable Chemicals Handling Instructions 1. Store all flammables in a dedicated flammables cabinet. 2. Keep cool, between 55°F and 80°F, at all times. 3. Store away from all sources of ignition. 4. Store away from all oxidizers. 5. Never store flammables in refrigerators unless the refrigerator is explosion proof. 6. Avoid storing any chemicals, especially flammable materials in direct sunlight.

Flammable Chemicals should be returned to the Chem Prep room for storage and Disposal.

10. Corrosive Materials Handling Instructions

1. Store corrosives in appropriate corrosives cabinets. 2. If possible, keep certain items in the original shipping package, e.g., acids and

bases in the special and expensive Styrofoam cubes. 3. Working with corrosive materials requires special eyewear. Wear a chemical

splash face shield when handling corrosive materials. 4. At least every three months inspect all shelf clips in your acid cabinet to check for

possible corrosion. These shelf clips are the only thing between you and a collapsed shelf. They require special attention.

5. Corrosive chemicals should be returned to the Chemistry Prep room for storage and/or removal by the chemical waste service.

11. Procedure Specific Safety Rules and Guidelines (for extremely hazardous chemicals)

1. Use a fume hood when the permissible exposure limit for a chemical is less than 50 ppm as indicated on the chemical MSDS.

2. Use carcinogens, mutagens, teratogens and allergens only under a fume hood. 3. Handle toxic, corrosive, flammable and noxious chemicals under a fume hood.


4. Do not expose flammable liquids to open flame, sparks, heat or any source of ignition. 5. Only use flammable solids (sodium, potassium, lithium, etc.) in very small quantities. 6. Use a safety shield when igniting flammable solids. 7. Water-‐reactive solids (sodium metal, potassium metal, etc.)should be stored under

dry oil. 8. Open cans of ether (ethyl ether should be properly disposed of after use and not

stored unless absolutely necessary. 9. Rely on expiration date to dispose of the material. 10. Glycerin should be available only to the instructor.

12. Prior Approval Procedures

1. There may be some procedures which require prior approval before an instructor attempts to perform them. These procedures must be determined by cooperation and communication between the Science Department and the Chemical Hygiene Officer.

13. Safety Equipment Inspection There are many safety items necessary for compliance to the Laboratory Standard. They include, but are not limited to:

• Eyewashes. • Fire extinguishers. • Goggles. • Respirators.

One of the most important sections of the Laboratory Standard States that all safety equipment in the facility must always be in good operating condition. While the Laboratory Standard requires some safety equipment and highly recommends other equipment, the standard is very clear on the point that if you have a piece of safety equipment, it must be functional at all times. This statement applies to all safety equipment, required or recommended.

• Goggles always must be clean and functional. • Laboratory ventilation must meet standards and be tested

quarterly. • A respirator must be fit tested and the appropriate cartridges

must be available. • Fire extinguishers must be the right type, and they must always be

properly inspected. • Eyewashes must be functional and flushed at least once a month. • Fume hoods must be operational at the level of 70-‐100 linear feet

per minute as measured by a velometer. 1. All of the above items and all safety equipment must be inspected every three months

at the minimum. 2. Any safety equipment failing this quarterly inspection or reported to be out of order at

any time must be repaired immediately. 3. Any safety equipment found to be out of order is a serious violation of the laboratory

standard.


Employee Training _______________________________ provides ongoing training sessions for our employees. Our training includes:

1. Content and location of this Chemical Hygiene Plan and The Laboratory Standard. 2. Potential hazards involved in using chemicals. 3. Signs and symptoms of overexposure to chemicals. How to detect potentially

harmful exposures before they are harmful. 4. Location and availability of chemical Material Safety Data Sheets (MSDS). 5. Understanding of the permissible exposure limits (PELs) used in the school. 6. The proper use and location of all safety equipment.

Exposure Evaluation

1. It is the communicated policy of ________________________________to

investigate all suspected overexposures to chemicals in a prompt and timely fashion. In the event of an overexposure, after the immediate event, we must document all chemicals and circumstances involved in the overexposure. This information should be used to change safety practices to further improve lab safety. It is our obligation to maintain these files and make them accessible to the employees.

2. Signs of overexposure are numerous; they include: a. Accidental breakage of a hazardous material container. b. A skin rash or irritation occurring because of contact with a chemical. c. Caustic splash to eyes, face or body. d. Symptoms such as nausea, dizziness and others.

3. If monitoring of the air is determined to be necessary, the results of the

monitoring must be made available to the employees within 2 weeks.

Medical Evaluations

1. It is the policy of _________________________________ to make medical

consultation and examination available to our employees when: a. Any sign or symptom of an overexposure to a chemical is present. b. Monitoring has indicated an overexposure to a chemical has occurred. c. There has been a spill or uncontrolled release of chemical fumes.

2. We will provide the physician with the names of the chemicals used, circumstances of the exposure and all signs and symptoms of the exposure.

3. The medical examinations dealing with the overexposure must be documented and other employees working under the same conditions must be notified. All


documentation must be kept on file and accessible by other employees working in this area.

4. All medical examinations and consultations shall be performed by or under the direct supervision of a licensed physician and shall be provided without cost to the employee, without loss of pay.

Monitoring

1. Monitoring will be necessary for substances regulated by a standard only if there

is reason to believe that exposure levels for that substance routinely exceed the PEL for that substance. If you have no cause to suspect a hazard or an exposure, no monitoring is necessary.

2. If monitoring is performed and this initial monitoring shows no evidence of exposure, the monitoring may be discontinued.

3. If initial monitoring indicates an exposure, steps must be taken immediately to reduce the exposure to permissible limits. Monitoring must then be performed periodically to verify that the steps to reduce the exposure have been effective. Monitoring may be terminated after complying with the applicable standard for the hazardous material.

4. All monitoring results and activities shall be fully accessible and in full knowledge of the employee(s).

Emergency Evacuation Plan

1. Establish a chain of communication. John tells Sally, Sally tells Bill, Bill notifies the office, the office notifies the fire department, etc.

2. Notify before proceeding to handle the incident. It is often better to notify someone else than to proceed in addressing the problem at hand by yourself.

3. Evacuation may or may not be necessary depending on the incident. 4. Once it has been determined evacuation is necessary, proceed in an orderly

fashion as you would in a fire drill evacuation. 5. Send everyone to a pre-‐designated area and then count heads to make sure

everyone is out of the building. 6. Proper evacuation procedures must be thoroughly planned, detailed in writing,

and properly communicated in advance. 7. ATTACH YOUR EMERGENCY EVACUATION PLAN.


Appendix


Appendix A: Ordering Chemicals for Educational Use Before ordering chemicals, teachers and other personnel should:

1. Make sure the chemical is not on the Chemicals of Concern list. 2. Be capable of assessing the hazards of chemicals. 3. Be sufficiently knowledgeable to recognize requests from others for

nonessential chemicals. 4. Have a current inventory of existing chemicals.

For each chemical used, ask the following questions:

1. Can proper storage be provided for the chemical? 2. Are the facilities appropriate for the use of the chemical? 3. Will the chemical or its end products require disposal as hazardous waste? 4. Is appropriate personal protective equipment available for safe use of the

chemical or its end product? 5. Have persons who will handle and use the chemical been trained in handling

these chemicals? Are they aware of the hazards?

Chemicals should be ordered in quantities consistent with the rate of use. Order in polyethylene bottles or plastic coated bottles, if available, to minimize breakage, corrosion, and rust.

Chemicals of Concern

Before making a request to use a chemical of concern, or if there is doubt about its value, the requestor should read and research the appropriate MSDS to determine whether the chemical can be safely used with students. The requestor also should consider the following:

Ø Relative hazard level of the chemical. Ø Educational value of using the chemical. Ø Teachers experience or lack of experience in using the substance. Ø Degree to which the laboratory is equipped for the safe use of the chemical.

1. A requestor who wishes to use a hazardous substance needs to submit a

request to the science supervisor in EBL.


Appendix B: Request for High Hazard Chemical

Please complete this form and give it to the EBL Science Supervisor for review. The Supervisor will make a final determination as to whether the chemical requested may be purchased.

Appendix C: Common Safety Symbols


Appendix D: Hazard Labels


Appendix E: Understanding an MSDS Section 1: details on what the chemical or substance is, CAS number, synonyms, the name of the company issuing the data sheet, and often an emergency contact number. Section 2: identifies the OSHA hazardous ingredients, and may include other key ingredients and exposure limits. Section 3: lists the major health effects associated with the chemical. Sometimes both the acute and chronic hazards are given. Section 4: provides first aid measures that should be initiated in case of exposure. Section 5: presents the fire-‐fighting measure to be taken. Section 6: details the procedures to be taken in case of accidental release. Section 7: addresses the storage and handling information for the chemical. Section 8: outlines the regulatory limits for exposure, usually the maximum permissible exposure limits (PEL). Section 9: gives the physical and chemical properties of the chemical. Information such as the evaporation rate, specific gravity, and flash points. Section 10: gives the stability and reactivity of the chemical with the information about chemical incompatibilities and conditions to avoid. Section 11: provides both the acute and chronic toxicity of chemical and any health effects that may be attributed to the chemical. Section 12: identifies both the ecotoxicity and the environmental fate of the chemical. Section 13: offers suggestions for the disposal of the chemical. Section 14: gives the transportation information required by the Department of Transportation. This often identifies the dangers associated with the chemical, such as flammability, toxicity, radioactivity, and reactivity. Section 15: outlines the regulatory information for the chemical. The hazard codes for the chemical are given along with the principle hazards associated with the chemical.


Section 16: provides additional information such as the label warnings, preparation and revision dates, names of the person or firm that prepared the MSDS, disclaimers, and references used to prepare the MSDS.


Appendix F: Chemical Storage 1. Take an inventory of all the chemicals in your school. 2. Decide what products you will need for the next year or two. Rid yourself of the

remainder of the accumulated materials. 3. Reorganize the remaining products into their compatible chemical families. The

actual sequence of compatible families on your shelves is not critical. What is important is to keep the compatible families separate and to keep the organic and inorganic families as far apart as possible. The suggested shelf pattern is only one suggested sequence you can use. If shelf space is a problem, you are permitted to place more than one compatible family on a shelf. Make sure you either have a physical divider or leave a 3” space between each family.

4. Avoid storing chemicals on the floor. 5. No top shelf chemical storage. 6. No chemicals stored above eye level. 7. Shelf assemblies are firmly secured to walls. Avoid island shelf assemblies. 8. Provide anti-‐roll-‐off lips on all shelves. 9. Ideally, shelving assemblies would be of wood construction. 10. Avoid adjustable metal shelf supports and clips. Better to use fixed, wooden

supports. 11. Store acids in a dedicated acid cabinet. Store nitric acid in the same cabinet only if

isolated from the other acids. Store both inorganic and some organic acids in the acid cabinet.

12. Store flammables in a dedicated flammable cabinet. 13. Store severe poisons in a dedicated poisons cabinet.
