Abstract
Exposure to asbestos (1332214) during the servicing of brakes on state owned vehicles at the Bureau of Vehicle Management Maintenance Division (SIC-7538), Harrisburg, Pennsylvania was investigated as part of a study of control technologies. Brakes had been serviced at this garage facility for the previous year using a BCE-1000 Clayton brake cleaning unit, sized for cars, vans, and pickups. The brake cleaning unit consisted of a transparent enclosure hood and a HEPA vacuum filter dust collector, designed to contain and collect all brake lining dust during vehicular brake maintenance and replacement. Real time dust aerosol concentrations in the air space adjacent to the Clayton unit both before, during the 5 minute brake cleaning cycle, and after this were obtained. With readings taken every 2 seconds, the observed readings over the entire testing period of about 15 minutes were in the range 0.08 to 0.12mg/m3. No real differences were noted between readings taken before brake cleaning, during brake cleaning, and after the conclusion of brake cleaning. The authors conclude that the Clayton BCE-1000 dust control unit appeared to be effective in containing and collecting brake dust during all vehicular brake maintenance and replacement jobs in this situation.
