Sinai School of Medicine in New York City indicate that brake dust may actually contain an average of 3 to 6 percent asbestos with some tests showing concentrations as high as 15 percent Samples of air were taken under actual working conditions in a fleet garage and & N.Y. Dept. of Sanitation truck repairshop These samples were analyzed by electron microscopy and Fig 2. NEVER BLOW OFF dirt from a brake assembly with an perenne salen ne air gun After vacuuming use a nearly damp rag revealed levels of airborne asbestos considerably higher than those permitted by federal law It should al be noted that during the testing in the truck repair- al natin shop grinding of brake shoes was carried out The work of the researchers at Mt. Sinal was fp discussed at a meeting of the National Institute for 1a Occupational Safety and Health NIOSH where the results of physical examinations given to 90 men oe who had been working as automobile and truck- ele brake repairmen for a period of 10 years were examined Of this small group the doctors stated Et that ray examinations showed that over onequarter had signs of abnormalities consistent with at asbestosis disease the same tests revealed that one bane quarter had also restrited restrited pulmonary lung func- tions This evidem rompted rompted NIOSH to issue an veated alert to the auto repair industry indicating that while the full cut cut of asbestos disease in service peel is not known because this occupational yr not been systematically studied up to wow energh scientific data has been accumulated to point out the need to start imme- diate control mensures so that the health hazard of asbestos can be mimizedl mimizedl There is no doubt that health hazard exists and Fig 1.
