Asbestos Dust

Particulate Matter Other Phan Systemic Poisons. SUica and asbestos dust produce fibrosis. SUicon carbide, carbon (other than exhaust emissions), and emery are iuert dusts. Many organic dusts, eg, poUen, wood, and resius, cause aUergic reactions. Acids, alkaUes, fluorides, and chromates are irritants. [Pg.95]

Animal experiments were undertaken to test the relationship 235 guinea pigs exposed to asbestos dusts were found to have asbestosis but no cancer (Vorwald and Karr, 1938), whereas only two pulmonary carcinomas were reported among ten surviving mice after 240 days of exposure to asbestos dust (Nordman and Sorge, 1941). One fortuitous but often cited animal experiment was that of pulmonary asbestosis reported in a dog who served for ten years as a ratter in an asbestos factory. The animal died of alveolar fibrosis and collapse as a result of diffuse distribution of asbestos in the lungs (Schuster, 1931). [Pg.104]

The contractor should seal off the work area from the rest of the residence and close off the heating/air conditioning system. Plastic sheeting and duct tape may be used, which can be carefully sealed with tape when work is complete. The contractor should take great care not to track asbestos dust into other areas of the residence. [Pg.91]

A nonprofit trade organization that acts as a clearinghouse for medical and technical information about asbestos and asbestos-related products, with emphasis on safety, health, and environmental issues. Works with government agencies to develop and implement industry-wide standards for exposure to asbestos dust emissions into community air and water and exchanges information on methods and techniques of asbestos dust control. Maintains a reference library on asbestos-related subjects. [Pg.269]
