In the mid 1970’s, government agencies and industries took various steps to caution and protect industrial workers that were exposed to asbestos. This was because associated health risks and asbestos related diseases like mesothelioma gained much attention during this time. In numerous cases, asbestos products were taken away from working environments, or employees were trained to use protective gear. However, the auto industry remains an exception to these precautionary trends.
Asbestos is still used in clutch facings and brake linings due to its heat resistant properties. Mechanics that repair or replace brakes could be in contact with asbestos regularly. New brakes are being made with asbestos, but the quantities have gone down. Removing worn out brakes to clean the brake drum can result in the accumulation of asbestos dust. Asbestos debris can also result from the beveling or grinding of clutch gaskets or new brakes, when they are being installed.
Tiny fibers of asbestos dust can get lodged deep in the lungs when inhaled. These needle-like fibers can cause irritation over time and eventually result in different kinds of lung problems including mesotheolima, the rare and deadly cancer. There is no doubt about auto workers being exposed to asbestos. However, whether auto mechanics, as a group, are at higher risk of contracting mesothelioma is yet to be decided.
In 1986, the EPA listed exposure to asbestos from clutches and brakes as the main cause of mesothelioma amongst auto mechanics. It issued official guidelines regarding the prevention of asbestos diseases in the auto repair industry. The Seattle Post-Intelligencer newspaper carried out a 4 month investigation and found alarmingly high rates of asbestos contamination in brake repair shops and gas stations. According to reports, some shops had exposure levels that were high enough to cause cancer in more than one out of 10 unprotected mechanics. Cancers like mesotheolima are considered incurable through conventional therapies.
