and Brake linings pads and clutch assemblies are made of asbestos which
has long been recognized as a material producing a hazard to the health of those who inhale its dust in excessive amounts over a long period of time During the last few years however attention has been focused on the development of cancer of the lung and other body areas following exposure
to asbestos dust
An alert concerning the potential health hazard for persons exposed to asbestos during the servicing of motor vehicle brake and clutch assemblies was issued by the National Institute for Occupational Safety and Health
on August 8 1975. NIOSH cited four cases of rare mesothelial tumors of
the pleura and peritoneum in persons who were employed in jobs involving brake servicing This rare type of cancer in the membrane around the lung causes 1 in 10,000 deaths in the general populace But one study of 632
asbestos workers found that 32 1 out of 20 had died of mesothelioma Asbestos also causes lung cancer and an asbestos worker who smokes is 90
times more likely to get lung cancer
The full extent of asbestos disease in brake servicing personnel is not known because this group has never before been systematically studied
Excessive dust concentrations measured at operations such as blow of
automobile drum brake assemblies grinding of used truck brake linings
employed bevelling of new truck brake linings and arcing of new auto brake linings
together with mesothelial tumors in persons so
affirms the necessity
for effectively controlling the exposure
At present we do not have complete information on how much exposure if any can be tolerated and so it is important to eliminate exposures whenever possible and minimize those which cannot be eliminated Recommended practices
are listed below
During brake servicing an air purifying respirator either single use or 1. with replaceable particulate filters as approved by the Mining Enforce-
ment and Safety Administration formerly Bureau of Mines or NIOSH should be worn during all procedures starting with the removal of the wheels and including reassembly During manual clutch servicing such a respirator should be worn during removal and cleaning of the clutch pressure plate and housing assembly and during installation of the new clutch assembly This should also include any arcing or riveting operations
should first be cleaned from brake drums brake backing plates brake
2. aDsussetmblies and clutch assemblies using an industrial type vacuum cleaner
equipped with a high efficiency filter system greater than 99 percent

After vacuum cleaning any
until
remaining dust should be removed using a ragcomsoparkeesdsedin awiarteorr adnrdy wbrruunsghing
nearly dry Under no circumstances should
be used for cleaning
or arcing wherever possible Some brake repair shops do
Avoid grinding no grinding at all
When grinding is performed the grinding arcing machine

bag of the arcing machine shall be removed and replaced with the hose of the high efficiency industrial vacuum described above
in areas where brakes and clutches are repaired should
All floor cleaning

be done with the high efficiency industrial vacuum
above
Grinding arcing machines should also be cleaned with such a with a damp cloth An approved
cleaner and any remaining dust wiped

respirator as described above
NIOSH also recommends the following procedures
