Characterization of the noise and vibration produced by the portable tools used in the automobile repair industry

Abstract

This study aimed to characterize the noise and vibration emissions of four classes of hand-held tools in Québec’s automobile repair shops, namely ratchets, air impact wrenches, grinders, sanders and air hammers. Workplace observations were used to determine representative tasks for each of them, and then to reproduce them in the laboratory by taking into account the action of the tool on the worked part. The results of the tests, categorized according to the frequency of use of the tool studied, show that sanders, grinders and ratchets produce the most worker vibration exposure. In the case of noise, sanders, grinders and ratchets produce the most exposure. To reduce exposure, the report recommends choosing rotating tools equipped with a silencer, as well as pneumatic hammers equipped with an anti-vibration system, and decreasing their use. Furthermore, compliance with the manufacturers’ instructions can slow the wear on the tools and thus help reduce their noise and hand-arm vibration risks.
