Abstract The report gives results of a brief field study that included measurement of personal, area, and environmental asbestos exposures resulting from wet and dry asbestos removal using a commercial vacuum system. Personal and area (indoor) asbestos concentrations during dry removal were less than 1 fiber/cu cm, as measured by NIOSH P and CAM 239 when the vacuum system was used. Asbestos released to the environment from the vacuum system's three-stage exhaust filter was negligible. Asbestos was released from the operator's protective garments when he exited the work area to service the vacuum system. Sources of asbestos fiber release associated with vacuum system operation were identified; these occurred during operation, disassembly, and asbestos disposal. Following vacuum shutdown, liquid drained from the collection reservoir due to inadequate door seals. During vacuum hose disassembly, bulk losses of asbestos-containing materials occurred. During disposal, the exterior of the vacuum truck became contaminated as the reservoir was emptied. Additional dry removal testing is required.
