Exposure Standard Documentation

Antimony trioxide, production

SUBSTANCE NAME:Antimony trioxide, production

CAS Number: 1309-64-4

For a few substances, usually the more potent probable and established human carcinogens, it is not currently possible to assign an appropriate exposure standard. For these substances, exposure should be controlled to the lowest practicable level.

Carcinogen category notice: Category 2. Probable human carcinogen for which there is sufficient evidence to provide a strong presumption that human exposure might result in the development of cancer. This evidence is generally based on appropriate long term animal studies, limited epidemiological evidence or other relevant information. See Chapter 13: Guidance Note on the Interpretation of Exposure Standards for Atmospheric Contaminants in the Occupational Environment, published by Worksafe Australia.

No standard should be applied without reference to Guidance on the interpretation of Workplace exposure standards for airborne contaminants.


Documentation notice

Documentation for the majority of substances can be found in the American Conference of Governmental Indistrial Hygienists' (ACGIH) documentation of the threshold limit values and biological exposure indices - users should refer to the ACGIH documentation cited.
