Abstract
A walk through survey of control technology for reducing asbestos (1332214) exposure during maintenance and repair of vehicular brakes was conducted at Northwest Local School District (SIC-8211), Cincinnati, Ohio in January, 1986. The primary method for controlling and collecting dust during brake servicing was a wet washing technique and good work practices, ensuring that exposure to hazardous physical or chemical agents was reduced or eliminated. Also available was an enclosed type brake assembly cleaner designed to be connected to the shop air and a vacuum system. The brake assembly cleaner did not have a viewing port to examine the area being cleaned. The operator had to remove the unit to inspect the cleaned area potentially exposing himself to any dust remaining on the brake shoes or hub. The unit itself was a potential dust source as it was designed to fit 16 inch wheels and did not form a tight seal on the smaller 15 inch wheels of the newer buses. The authors conclude that the wet wash technique is an excellent method for controlling asbestos emissions during brake maintenance. The vacuum brake assembly cleaner is inadequate and potentially hazardous. An in depth survey of the wet technique is recommended.
