NIOSH 1988 Aug:5 pages
An evaluation was made of various control technologies designed to reduce asbestos (1332214) exposures during brake drum servicing at Indianapolis Power and Light Company (SIC-4931), Indianapolis, Indiana. The garage at this facility serviced about 425 vehicles each year with about 200 brake repair jobs being done annually. During servicing a regular wet and dry vacuum cleaner was used, along with a steam jenny containing liquid soap, and a liquid spray can. Once the wheel was removed, the entire hub area was sprayed with steam foam at 90 pounds per square inch from the steam jenny containing liquid soap. The hub area was vacuumed prior to and following removal. The vacuum cleaner was not equipped with a HEPA filter. A liquid spray can was used to clean the plates. The brake shoe area was vacuumed. Once the brake area was free of all accumulated dust, the brakes were serviced. The author concludes that control measures did not appear to be sufficient to keep asbestos dust from emanating into the atmosphere. The facility was not selected for an in depth evaluation.
