B. 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 or brea th. pain in the walls of the chest, and/ or abdominal pain.. the escape of asbestos fibers. During the; a dry broom; 111. Respirators and Protective Clothing installation of enclosures, tools that-are u9ed [such as drills or rivet tools) should be equipped with HEPA-filtered vacuums. Before constructing the enclosure.,all electrical conduits, telephone lines., recessed lighjs. and pipeB in the area to be enclosed should be moved tb ensure that the enclosure will not have to be re-opened later, for routine or emergency maintenance;. If such lights or other equipment cannot be moved to a- new location for logistic reasons.,or if moving them will disturb the asbestos-containing materials; removal rather than enclosure .of the asbestos-containing.materials is the appropriate control method to use. Not to use an ordinary vacuum to dean up asbestos-containing debris; Not to remove ceiling tiles below asbestos-containing materials without wearing the proper respiratory protection, clearing the area of other people, and observing1 asbestos removal waste disposal procedures; Not to remove ventilation system filters dry; and Not to shake ventilation system filters. Appendix H to 1926.58--Substonce Technical Information for Asbestos, NonMandatory 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 can occur while your employer is in the process of installing engineering controls to reduce asbestos, . tremolite, anthophyllite and actinolite exposure, or where engineering controls are not feasible to reduce asbestos, tremolite. anthophyllite and actinolite exposure.
