Of the nearly one million Use of the common sense NJOSH guidelines will mean greater shop safety and could help you pass OSHA industrial hygiene inspection. tons of asbestos "consumed" in the United States in 1972, approximately 77% was used in the construction in- du~try. However, further statistics reveal that only 500,000 workers are exposed to asbestos in mining, milling, fabrication and con~truction. Compare that number With the nearly ulle million American workers exposed to asbestos while installing and/or mdintaining clut.:h and brake linings! A smaller percentage of the total asbl.!sto~ i~ consumed but a larger percentage of Amenca's work force is exposed. But how serious is the exposure? A 1975 study done by Or. W.J. Nichohon of MI. Sinai Hospital detailed in a paper entitled ..Asbe,tos Exposure During Brake Lining Maintenance and Repair" rey~als some interesting statistics . Before studies were undertaken, it was thought that the heat involved during the use of brakes caused a chemical breakdown, transforming the a~bestos in the linings into a rdatively harmle,s du~t. The data presented in the paper indic:ltes that workers engased in car and truck brake service are expo,eJ to potentially hazardous levels of airborne asbestos du~t. 1 ..

A recent review of scientific literature, quoted in an ASIA news bulletin, slates that "the as~ociation between asbeslos expo~ure and [tumors of the ChC:H and abdominal membranes] has revealed at least four ca~es of thc!te rare tulllors in persons who were employed in jobs inVOlving automobile brake servicing." (Researchers have just begun to pinpoint this industry. Other related cases are expected to be found.)
