A survey of technology for controlling exposure to asbestos (1332214) during brake drum service operators was conducted at the Louisville Gas and Electric Company (SIC-4931), Louisville, Kentucky in October, 1985. The major component of the engineering control system was a Nilfisk Asbestos/Clene system that removed asbestos fibers generated while servicing the brakes. Each system consisted of a filtered dust collector and a brake encapsulation cylinder. Compressed air directed by the mechanic dislodged asbestos dust from the exposed brake mechanism. The loosened dust within the cylinder was exhausted directly into the collector and trapped in disposable bags. The workers were encouraged to use good work practices, such as completely vacuuming all exposed parts prior to handling, gently removing and handling all contaminated parts, and consistently using all required personal protective equipment. The workers used approved masks. All employees were given annual chest X-rays and pulmonary function tests. The author concludes that the facility's vehicular brake servicing facility appears to be well designed and maintained. An in depth survey is recommended.
