The intent of this inventory is to identify all hazardous and radioactive materials. Hazardous chemicals purchased since the mid-1980's should have hazard warnings on the container label which will aid laboratory personnel in determining what chemicals should be included on the inventory. Chemicals purchased prior to that time are 20 years old and likely need to be disposed of. Information on proper disposal of hazardous chemicals can be found in the Waste Disposal section of the DEHS web site. Radioactive materials can be identified by a label as well. Radioactive materials have been required to have identifying labels since the early 1970’s. Materials that are non-hazardous do not have to be placed on the inventory.

List the following materials on the inventory:

1. Flammable and Combustible Liquids - Flash Point < 200 deg. F.
2. Compressed gases of any type
3. Flammable solids
4. Air and/or water reactive materials
5. Toxic/poisonous materials
6. Organic Peroxide and other oxidizers
7. Pyrophoric materials
8. Unstable chemicals
9. Radioactive materials
10. Corrosive acids and bases
11. Carcinogens
12. Controlled Substances

Materials that should not be listed on the inventory:

1. Amino acids
2. Salts
3. Buffer solutions
4. Non-hazardous materials
5. Soaps/surfactants
6. Silicas
7. Assay or other testing kits
8. IV fluids and drugs that are neither controlled substances or hazardous materials

To assist you in creating an inventory, a chemical inventory template has been developed by DEHS. Other formats are acceptable as long as they contain the same information.
