The effectiveness of various controls used by the asbestos (1332214) abatement industry to control asbestos contamination at its source was evaluated. The glove bag control method to prevent exposure in workplaces was used during the removal of asbestos pipe lagging from the Bloom Middle School, Cincinnati, Ohio by I and F Corporation (SIC-1799). The removal contract required about 1,800 linear feet of asbestos pipe lagging to be removed from 15 major rooms and areas of the building. General operation included initial site clean up, clearance of all movable materials, and site isolation by sealing off all access with plastic sheeting taped to windows, air vents, and doors. Two entrance and egress contamination control facilities were established. Materials to be removed were wetted as they were removed from structures they covered, and wet debris was collected and removed from the area. Workers wore protective clothing and respiratory protective equipment. Glove bags proved to be a useful approach to removing asbestos at this location. However, the glove bags did not provide complete containment of the asbestos being removed; asbestos fiber concentrations in breathing zone air samples rose from a preremoval level of 0.004 fibers per cubic centimeter (f/cc) to 0.034f/cc during preparation of the pipe lagging for removal and to 0.312f/cc during removal in glove bags. A number of recommended work practices for such procedures were presented.
