It has been general knowledge that linings and pads are made on the average of 60 to 60 percent asbestos. However, past studies have led us to believe that the asbestos fiber was locked into other materials in the lining and that a change due to the high heat of friction took place during braking or dutch application. This transformed the asbestos fiber into a non-toxic, nnn-fibrou* material called fonterite. The conclusion then was that the dust wsj harmless. Studies conducted by the MU 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 IS percent. Samples of air were taken under actual working conditions in a taxi-fleet garxgo and a N.Y. Dept, of Sanitation truck repairahop.

Of this small group tha doctors stated that X-ray examinations showed that over one* qnarter had signs of abnormalitiaa consistent with asbectosis discus; the u m c tests revealed that one quarter had also restricted pulmonary (lung) func tions.

There are some authorities and oth er studies that place the percentage of asbestos in brake dust at s much lower level than those reported by the Mt. Sinai group and disagree with its findings. All authorities agree that no m atter how smsll the concentration of asbestos in brake and clutch dust, '.here is an immediate noed to initiate work practices :n every shop that will eliminate any risk to the health of mechanics. The danger is associated with drilling, grinding and cutting of brake linings. The dust generated during these operations must be collected In e vacuum-recovery system that has a high-efAciency filter. Many older grinders either have no recovery system or are equipped with vseunms that allow tiny particles of asbestos fiber to be blown into the sir. Buying pre-ground shoes will minimize the need for grinding. ' Where possible, a separate area should be set tside for brake and dutch work and a sign posted at the entrance that reads: ASBESTOS DUST HAZARD. AVOID BREATHING DUST. WEAR ASSIGNED PROTECTIVE EQUIPMENT. DO NOT REMAIN IN AREA UNLESS YOUR WORK REQUIRES IT. BREATHING ASBESTOS DUST MAY BE HAZARDOUS TO YOUR HEALTH. Oust should never be removed from a brake or clutch assembly with an air blowgua or by brushing. The only way to safely dean dust containing asbestos is with an industrial-type vacuum with a high efficiency filtering eystem (Fig. 1). Don't uie one of your wife's old vacuum cleaners because it probably will do more harm than rood. The fine particles of asbestoe will pass through most vseuum cleaners and you will end up with a higher concen tration of asbestos than you would have if you hadn't used the vacuum a t aH The vacuum you buy should have a 99-percent efficiency for OJ micrometers diameter aerosols. If thars is any remaining dust that was not removed by vacuuming, wash it off using a slightly damp rag. Under no circumstances should you use an air gun or dry brush (Fig. 2). 76 - There is no point in being careful shout vacuuming the dust if, when you empty the vacuum cleaner bag. the dust blows all around you and the shop. Brake and clutch dust should be diepoeed of in s epeclsl plastic bag marked as follows: CAUTION: CONTAINS ASBESTOS FIBERS. AVOID BREATHING DUST. BREATHING ASBESTOS DUST MAY CAUSE SERIOUS BODILY HARM. Even using a hlgh-cfficiency industrial vacuum eleaner will not prevent a small amount of dust from reaching some noees and mouths which anil inhale it To prevent this, you ehouid wear an air-purifying respirator of aither the throwaway type like those used in body shope or one with a replaceable particu late filter. Before you buy cither type, be sure that it is approved by NIOSH or tha Mining Enforcement and Safety Administration. Wear the respirator while you are operating a grinder, drill,or when emptying the dust collection bags on your"vacuum cleaner. There ia bound to bo aoma brake and clutch dust that falls to the floor while you are working, so be sure to use an industrial vacuum cleaner to pick it up.

The rest is eommon sense: If your shop hss heavy accumulations of dust on loektrs, parts shelves, overhead door channels, beams and on window sills there is a good chance that dust contains somt asbestos.
