According to the OSHA Hazard Communication Standard (1910.1200), a hazard determination must consider the chemicals listed in the following sources to be hazardous:
Chemicals regulated by OSHA in 29 CFR Part 1910, Subpart Z.
Threshold Limit Values for Chemical Substances and Physical Agents in the Work Environment, American Conference of Government Industrial Hygienists (latest edition).
National Toxicology Program, Annual Report on Carcinogens (latest edition).
International Agency for Research on Cancer Monographs (latest edition).
The fact that a chemical is not listed does not mean it is not hazardous. Any chemical that presents a potential health or physical hazard to which employees may be exposed must be included in the hazard communication program.
Conversely, some of the substances listed present no danger at the exposure levels likely to be encountered at ESF. Consult the MSDS for the specific chemicals in question.
The United States Environmental Protection Agency, and the New York State Department of Environmental Conservation regulate hazardous waste. For definitions to identify, as well as manage hazardous waste, see Appendix L.
