Asbestos carcinogenic classification

DOT CLASSIFICATION 9 Label CLASS 9 SAFETY PROFILE Confirmed human carcinogen. See also other asbestos entries. 

Classification in category 1 is based on epidemiological investigations, primarily from occupational medicine observations from real workplaces in industry and trade. Clear evidence of activation of tumors after exposure to a substance means that it has to be classified in category 1. Production and usage of many well-known human carcinogens are banned, and their acceptable concentration in products is also severely limited. Examples are benzidine, p-naphthylamine, and asbestos. 

For classification of carcinogens in categories 1 and 2, the danger symbol T with the danger identification toxic and the R-phrases 45 or 49 have to be used. R 49 Hmits usage in which there is an inhala-tive cancer risk of the respiratory tract caused from dust, fibers, or H-quid aerosols. Typical examples are asbestos, chromium(Vl) compounds, and cadmium chloride.
