It should lie noted that during the testing in the truck repair(hop grinding nf brake shoes was carried out TTic work of the researchers at ML Sinai was discussed at a meeting of the Nnllnnal Institute for Occupational Safety and Health (NIOSH) where the results of physical examination* given to 90 men who had been working aa automobile and truckbrake repairmen for a period nf 10 years were examined. Of this small group the doctor* stated that X-ray examinations showed that over onequarter had signs nf abnormalities consistent with aslamlnsis disease; the same testa revealed that one quarter had also restricted pulmnnary (lung) func tions. This evidence prompted NIOSH to issue an alert to the automobile re|tair industry Indicating that while the full rxtuot of asla-stisi-rclalcii disease in hrake-servicc personnel is hot known hecause thia occupational group has not been systematically studied up to now, enough scientific data has been accumulated to point out the need to start imme diate control measure* so that the health hazard of aslieslos can be minimized. There la no doubt that a health hazard oxiita and that exposure to asbestos fibers can increase the risk nmtinued on page 7t MOTOR.

There are anme authorities and other studies that place the percentage of aabcatoa in brake dual at a much lower level than th<e reported by the ML Sinai croup and disagree with its Undines. AH authorities aerve that no matter how small the concentration of axls-stiis in brake and dutch dust, there is an immediate need to initiate walk practice* in every shop that will eliminate any riak to the health of mechanics. The dancer is associated with dritlinc. grinding ami euttinc "f brake linincs. The dust generated durinc these o|terations must In- collected in a vwuum-recovery system that has a high-clRciency Alter. Many older crindera either have no recovery system or are cquipiied with vacuums that allow tiny particles of bsIh,sIos AInt to.Ik* blown into the air. Buying pre-ground shoes will minimiac the need for frindinc. Where possible, a separate area should be set uide for hrakc and clutch 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. Dust should never be removed from a brake or dutch assembly with an air Mmrgun or by lirushing. The only wuy t safely dean dust containing asls-stos is with an industrial-type varuum with a high efficiency' filterinc system (Fig. 1). Don't use one of your wife's old vacuum dcancre because it probably will do more harm than good. The fine particle* of axis-stmt will |nss through most varuum cleaner* and you will end up with a higher concen tration of aslwstos than you would have if you hadn't used the varuum at all. The vacuum you huy should have a 99-pcrecnt efficiency foe 0.3 micrometeri diameter aensuds. If there is any remaining dust that was not removed by vacuuming, wash it off using a slightly damp rag. Under no circumstance* should you use an air gun or dry brush (Fig. 2k 76 There is m> |*iint hn lo-iwg enreful almut vacuuming the dust if. when you empty the vacuum cleaner bag. the dust blows all around you and the shop. Brake and dutch dust should lie disposed of in a special plastic bag marked as follows: CAUTION: CONTAINS ASBESTOS FIBERS. AVOID BREATHING DUST. BREATHING ASBESTOS DU8T MAY CAUSE SERIOUS BODILY HARM. Even using a high-efficiency Industrial vacuum dcaner will not prevent a small amount of dust from reaching some nose* ami mouth* which will inhale it. To iirevenl this, you should wear an air*|Hirif,ving respirator of cither the throwaway type1 like those used in laxly *h<i|t* nr one with a replaceable particu late Alter. Before you buy either ty|ic, be sure that It is approved by NIOSH or the Mining Enforcement and Safety Administration. Wear the respirator while you are oj>eraling a grinder, drill or when emptying the dust collection bagi on your vacuum deancr. Thera la bound to be some breke and dutch dust (hat falls to the ffaor while you arc working, so be sure to use an industrial varuum cleaner to pick it up. Don't sweep thi* part of the shop with a broom. A broom ha* the tendency to flick the asbestoa particles up into the air and that is where they are dangerous. The rest is common sense: If your shop has heavy accumulations of dust on lockers, parts shelves, overhead door channels. Imams and on window sills there is a good chance that dust contains some aslicstos. Wear your respirator and use your vacuum dcaner to go over all those hidden places carefully ami dean up the dust. Change your work chithes regularly and don't bring them home. Have them washed by an industrial laundry. Wash your hands thoroughly before eating and avoid eating in the area where you do hrakc and dutch work. Every shop, large or small. Is responsible for meeting the nsiuiremrnt* of the federal Isw which calls for Industrial hygiene ins|s-elinns rarried out by 08HA representatives. Under thi* law the level of asbestoa shall not exceed 2 Alter* longer than 5 micrometers per cubic centimeter of air.
