HEALTH HAZARD INFORMATION I tlv { t3-t>ers/cc (See Sect ^1 ----------------------------------------------------------------------------------------------------------------------------1---------------------l:m in length As a particulate :.a:eria., chrysotile asbestos can be irritating to the respiratory -TT skin or eyes. However, the significant industrial hazards arise from excessive 'dusr inhalation with damage requiring years to become evident. Chronic inhalation of hi-- levels of asbestos particles can produce asbestosis, a disabling fibrosis of the ! which gradually reduces lur.g capacity ana emciency. (Usually over 4 years is re: L for a serious condition to develop.) Excessive inhalation can also cause pleural -'L a thickening of the lung lining. Compliance with TLV is expected to control these~"=y: '. Cancer car. result from excessive inhalation of asbestos particulate, which mav requtrdecaaes to develop. Lung cancer is a special risk to those who smoke cigarectes r-(. ularly in addicion to having asDestos exposure. Rare mesotheliomas of the pleura ;- peritoneum (lining around the lungs or abdominal cavity) and possibly cancers of cr* Cl tract and larynx (also smoking related) have been associated with inhalation ex:--,., to asbestos particles. (Crocidolite asbestos has been suggested as the major meso- | thelioma risk.) j In groups of workers exposed to asbestos, lung cancer death is 3 or 4 times more cor.-:- i than mesothelioma death, and 97.5" of asbestos-related lung cancers occur with thos<> I workers who also smoke cigareTTes? tor non-smokers aseescos exposure" increases ETsTT ; oT lung cancer 5X. ~ '| SECTION VII, SPILL, uEAK, AND DISPOSAL PROCEDURES______________ Nocify safety personnel of spills! Exclude all from spill area except crained clear.-, personnel who have approved respiratory protection against dust. Provide exhaust ventilation with capture filtration, but do not stir up the dust. Use a wet methoc an approved vacuum cleaning system to picx up spills. the techniques used must col lect particulate without dispersing dust into the air. Waste must be placed in dus:-. tighc containers or sealed plastic bags for disposal. Label properly! DISPOSAL: Deposit waste containers in a secured landfill where asbestos will remain buried. Follow Federal, State and local regulations. Also note chat chrysotile , be converted into non-asbescos waste by heating at high temperature (see Secr.V). i 1 SECTION VIII. SPECIAL PROTECTION INFORMATION Provide exhaust ventilation and capture filtration to remove airborne asbestos parcic- from the workplace (as much as possible) without dispersing it into the environment Isolate work areas (also post signs) where asbestos particulate may occur at excess- levels. For nonroutine or emergency conditions where excessive dust is present, approved rest-' ators must be used: Single use or re-usable air-purifying respiratory up to 10X full-facepiece powered air-purifying respirator up to 100X TLV; full-facepiece air- supplied (continuous flow or pressure-demand type) respirator above 100X TLV. Depending on exposure levels, it may be necessary to provide body-covering work clothes special vacuuming facilities for clothes and suitable laundering or disposal arrange" ments, change areas with dual lockering facilities, shoverB before changing to street clothing after work, etc. Be sure workers do not carry asbestos dust home on their clothing or person. Prevent asbestos dust from being carried to rest rooms, to eat- areas, to non-asbestos workplaces, etc. __________ ____ SECTION IX. SPECIAL PRECAUTIONS AND COMMENTS Store asbestos in closed containers (dust tight!) in a clean, secure area. Protect tainers from physical damage. Do not open containers that can release asbestos - U S * without providing proper enclosure measures at all stages of asbestos or control handling, measures. Use dust suppression cor. use and disposal. Follow good house it e c ing practices CO prevent accumulations of asbestoa-containing dust. Avoid inhaia of asbestos. The effeces on cancer incidence of chronic exposure are not yet fui known. Monitor areas where asbestos dust is present to be sure of worker expoaur e levels; keep records to define exposures and retain for at least 20 years.
