It has been general knowledge thatlirllll. ,';d pads are made on the an'rage or 50 to nO I'" , 'It asbestos. However. past studies have h'd J. l" believe that the asbestos tiher was locked into. ,tllt'r materials in the lining and that a change due t(. the high heat of friction took place during hrakin~ or clutch application. This transformed the asbestos fiber into a non-toxic, non-fibrous material called Corsterite. The conclusion then was that the dust was harmless. Studies conducted by the Mt. 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 oC air were taken under actual working conditions in a taxi-fleet garage and & N.Y. Dept. of Sanitation truck repairshop. These .ampl.ea were analyzed by electron microscopy and Fig. 2. NEVER BLOW OFF dirt from a brake assembly with an air gun. After vacuuming, use a nearly-dry damp ra,. .~ Fie. 1. REMOVE BRAKE DUST WIth high.efficiency filtered indiJswl vacuum cleaner. Wear ilrpurifying respirator. revealed levels of airborne asbestos considerably higher than those permitted by federal law. It should be noted that during the testi,ng in the truck repair- shop grinding of brake shoes was carried out. The work of the researchers at Mt. Sinal was discussed at a meeting of the National Institute for Occupational Safety and Health (NIOSH) where the results of physical examinations giyen to 90 men who had been working as automobile and truck- brake repairmen for a period of 10 years were examined. Of this small group the doctors stated that X-ray examinations showed that over one- quarter had signs of almormalities l'onsistent with asbestosis disease; th, ,ame tests revealed that one quarter had also rp,,' r led pulmonary (lung) func-. lions.
