A walk through survey was conducted to assess methods used to control occupational exposure to asbestos (1332214) at the General Motors Inland Division (SIC-3714) at Vandalia, Ohio, in May 1983. The facility used engineering controls, housekeeping, and monitoring of employees to control exposure when bags of asbestos were opened and emptied into a hopper. Local exhaust ventilation was the primary engineering control. The exhaust system was designed into the hopper. Continuous monitoring of airborne asbestos concentrations was performed. The usual worker exposure was less than 0.5 fibers per cubic centimeter according to the factory's hygienist. The workers were taught to use practices that minimized asbestos emissions and exposures. Potential emission sources could result from broken bags and emptying the bag hopper. The bag supplier had made the bags stronger, and each pallet of bags was shrink wrapped to minimize breaking. The author concludes that monitoring the ambient air serves a feedback function as it provides the basis for corrective action. Controls to reduce asbestos exposures are effective. It is recommended that NIOSH conduct a detailed survey of this operation.
