Abstract
High velocity low volume technology (HVLV) in the asbestos (1332214) removal industry was investigated at the Duall Company (SIC-1795), Mt. Laurel, New Jersey, on March 22, 1983. Work processes involved covering all interior surfaces containing asbestos, constructing a controlled area entrance with a double passage to act as an air lock, and the use of high volume ultra high efficiency filtration units to maintain negative air pressure in the controlled area to reduce airborne fiber count. Work practices were essential in minimizing asbestos exposure. Proper wetting of materials was very important, as was care in providing dust tight barriers, and decontamination. Since fibers were found to penetrate protective coveralls, proper attention to hygiene in the decontamination procedures was stressed. Monitoring was an integral part of control procedures. Respiratory protection was required at all times in the controlled area. Other unique practices included maintenance of a computerized data base of filter and bulk monitoring data from 40 different job sites. The author concludes that the Duall asbestos removal activities are remarkably well controlled; however, there are no applications of HVLV systems because the volume of material removed and the larger pieces of debris are not amenable to vacuum removal.
