US OSHA - Carcinogens
OSHA Carcinogens are compiled from three sources:
1. National Toxicology Program (NTP), "Annual Report on Carcinogens" (Latest Editions) (known or possibly carcinogenic) ;
2. International Agency for Research on Cancer (IARC) "Monographs" (Latest Editions) ((category 1, 2A & 2B);
3. 29 CFR 1910, Subpart Z, Toxic and Hazardous Substances, Occupational Safety and Health Administration (listed).
This is a list of TRI chemicals that are classified as carcinogens under the requirements of the Occupation Safety and Health Administration (OSHA) and, the basis of the classifications. OSHA carcinogens have a 0.1% de minimis concentration limit instead of 1%. Amounts of TRI chemicals present below the de minimis concentration limit in mixtures do not have to be included in threshold determinations or release and other waste management calculations.
