Exposure to asbestos, tremolite, anthophyllite and actinolite has been shown to cause lung cancer, mesothelioma, and cancer of the stomach and colon. Mesothelioma is a rare cancer of the thin membrane lining of the chest and abdomen. Symptoms of mesothelioma include shortness of breath, pain in the walls of the chest, and/ or abdominal pain.. the escape of asbestos fibers. During the; a dry broom: 111.

Appendix H (o 1926.58--Substance Technical Information for Asbestos, NonMandatory (. Substance Identification A. Substance: `-'Asbestos" is the name of a class of magnesium-silicate minerals that occur in fibrous form. Minerals that ore included in this group are chrysotile. crocidolite, amosite. anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. B. Asbestos, tremolite. anihophyjjile. and actinolite arc used in the manufacture of A. Respirators: You are required to wear a respirator when performing tasks that result in asbestos, tremolite, anthophyllite and actinolite exposure that exceeds the permissible exposure limit (PEL) of 0.2 f/cc. These conditions cori occur while your employer is in the process of installing engineering controls to reduce asbestos, . tremolite, anthophyllite and actinolite exposure, or where engineering controls ere not feasible to reduce asbestos, tremolite. anthophyllite and actinolite exposure. Airpurifying respirators equipped with a high-' efficiency particulate air (HEPA) filter can be used where airborne asbestos, tremolite, anthophyllite and actinolite fiber concentrations do no! exceed 2 f/cc; otherwise, airrsupplied. positive-pressure, full facbpiece respirators must be used. Disposable respirators or dust masks are not permitted to be used for asbestos, tremolite, anthophyllite and actinolite work.
