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. 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. District Responsibilities: 1. Record all employee exposures to hazardous chemicals.

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.

CSD Chemical Hygiene Plan

10

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. 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: 1. Eyewashes. 2. Fire extinguishers. 3. Goggles. 4. 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. 1. Goggles always must be clean and functional. 2. Laboratory ventilation must meet standards and be tested quarterly. 3. A respirator must be fit tested and the appropriate cartridges must be available. 4. Fire extinguishers must be the right type, and they must always be properly inspected. 5. Eyewashes must be functional and flushed at least once a month. 6. Fume hoods must be operational at the level of 70-100 linear feet per minute as measured by a velometer. All of the above items and all safety equipment must be inspected every three months at the Minimum. Any safety equipment failing this quarterly inspection or reported to be out of order at any time must be repaired immediately. Any safety equipment found to be out of order is a serious violation of the laboratory standard. 9.Rely on expiration date to dispose of the material. 10. Glycerin should be available only to the instructor. 12. Prior Approval Procedures

14. Emergency Evacuation Plan Establish a chain of communication. John tells Sally, Sally tells Bill, Bill notifies the Office, the office notifies the fire department, etc. Remember, 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.

Evacuation may or may not be necessary depending on the incident. Once it has been Determined evacuation is necessary, proceed in an orderly fashion as you would in a Fire drill evacuation. Send everyone to a pre-designated area and then count heads To make sure everyone is out of the building. Proper evacuation procedures must be thoroughly planned, detailed in writing, and Properly communicated in advance. In case of an emergency, you will not have time To determine “What do I do nest?”. This evacuation will be part of the Chemical Hygiene Plan.

SUGGESTED SEQUENCE OF STEPS TO MORE SAFELY ORGANIZE YOUR SCHOOL’S CHEMICAL STORES AREA

Take an inventory of all the chemicals in your school. You will never know the extent of your problem until you know exactly what you have. Record the inventory. You may want to consider the purchase of the FLINN CHEMICAL INVENTORY SYSTEM to facilitate this task.

2

1

Decide what products you will need for the next year (at best, two years). Ruthlessly rid yourselves of the remainder of the accumulated materials.

Reorganize the remaining products into their compatible chemical families (see our Suggested Chemical Storage Pattern on page 1075). 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 Storage Pattern shown on pages 1075–1076 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. Hundreds of teachers who have reorganized their shelves, using these patterns, tell us products are easier to find versus the alphabetical system previously used. When you reorganize, you may need some estimate of the percentage of shelf space each family might occupy. If yours is a “typical” high school, the following profile may be a helpful guide: 3

Inorganic Families

Families

Percentage of Shelf Space Occupied Store away from all other items. Store in a dedicated acid cabinet. Store nitric acid away from all other materials.

Families

Percentage of Shelf Space Occupied

Acids

Sulfides, etc. (Inorganic 5) Chlorates,

Less than 1%

(Inorganic 9)

5+%

Metals, etc.

Less than 5%

Perchlorates, etc. (Inorganic 6) Arsenates, etc. (Inorganic 7) Borates, Chromates, etc. (Inorganic 8) Sulfur, Phosphorus, etc. (Inorganic 10)

(Inorganic 1) Halides, Sulfates,

Could be 35–40% of available space. This is usually the largest family.

Less than 1%

Phosphates, Acetates, etc. (Inorganic 2) Nitrates, etc. (Inorganic 3) Hydroxides, Oxides, etc. (Inorganic 4)

Less than 1%

Approximately 8–10%

Approximately 3%

Approximately 10%

4

And Organic Families Organic acids (Organic 1) will probably occupy about 5+% of your organic shelf space except for acetic acid which should be stored with the inorganic acids (hydrochloric, etc.) in a dedicated acid cabinet. Keep acetic acid away from nitric acid. If your school is “typical,” the remainder of your organic materials may occupy about 15–20% of your total shelf space. You should store all flammable organics in a dedicated flammables cabinet.

5

And Other Materials There may be some very large space consumers in 2-kilogram (5-lb.) containers; i.e., calcium chloride, calcium hydroxide, etc. Certainly you may wish to extend family storage in a separate location for such large volumes of large packages.

Congratulations! You have now reorganized your chemical stores facility to: • store compatible products together • lock up all poisons • separate acids into dedicated storage • record all inventory • separate flammables into dedicated storage

• rid yourselves of excess materials

YOU NOW HAVE A SAFER FACILITY

SUGGESTED CHEMICAL STORAGE PATTERN Storage of laboratory chemicals presents an ongoing safety hazard for school science departments. There are many chemicals that are incompatible with each other. The common method of storing these products in alphabetical order sometimes results in incompatible neighbors. For example, storing strong oxidizing materials next to organic chemicals can present a hazard. A possible solution is to separate chemicals into their organic and inorganic families and then to further divide the materials into related and compatible families. Below is a list of compatible families. On the next page you will find this family arrangement pictured as shelf areas in your chemical stores area. The pictured shelf arrange- ment will easily enable you to rearrange your inventory into a safer and more compatible environment.

Inorganic

Organic 1. Acids, Amino Acids, Anhydrides, Peracids 2. Alcohols, Glycols, Sugars, Amines, Amides, Imines, Imides

1. Metals, Hydrides 2. Acetates, Halides, Iodides, Sulfates, Sulfites, Thiosulfates, Phosphates, Halogens, Oxalates, Phthalates, Oleates 3. Amides, Nitrates (except Ammonium Nitrate), Nitrites, Azides 4. Hydroxides, Oxides, Silicates, Carbonates, Carbon 5. Sulfides, Selenides, Phosphides, Carbides, Nitrides 6. Chlorates, Bromates, Iodates, Chlorites, Hypochlorites, Perchlorates, Perchloric Acid, Peroxides, Hydrogen Peroxide 7. Arsenates, Cyanides, Cyanates 8. Borates, Chromates, Manganates, Permanganates, Molybdates, Vanadates 9. Acids (except Nitric) (Nitric Acid is isolated and stored by itself.) 10. Sulfur, Phosphorus, Arsenic, Phosphorus Pentoxide 11. Inorganic miscellaneous

3. Hydrocarbons, Esters, Aldehydes, Oils 4. Ethers, Ketones, Ketenes, Halogenated Hydrocarbons, Ethylene Oxide 5. Epoxy Compounds, Isocyanates 6. Peroxides, Hydroperoxides, Azides 7. Sulfides, Polysulfides, Sulfoxides, Nitriles 8. Phenols, Cresols

9. Dyes, Stains, Indicators 10. Organic miscellaneous

NOTE: If you store volatile materials (ether, hydrocarbons, etc.) in a refrigerator, the refrigerator must be explosion-proof. The thermostat switch or light switch in a standard refrigerator may spark and set off the volatile fumes inside and thus cause an explosion.

This list is not complete and is intended only to cover the materials possibly found in an average school situation. This is not the only method of arranging these materials and is only offered as a suggestion.

See the next three pages for detailed inventory and storage steps you might follow to vastly improve the safety profile of your chemical storage.
