• Description:
  The effectiveness of the glove bag control method to prevent exposure to asbestos (1332214) during removal of asbestos pipe lagging from the Washburn Elementary School (SIC-1799) in Cincinnati, Ohio, was evaluated. During this work, the method appeared to function well in controlling worker exposures to asbestos fibers. It is recommended that workers use respiratory protection in any glove bag work due to possible leakage. During removal operations, asbestos fiber concentrations rose from a preremoval level of 0.002 fibers per cubic centimeter (f/cc) to limited experience with the glove bag technique; the authors suggest that this is common for individuals required to use this method. The authors conclude that a secondary containment system should be used as an adjunct to the glove bag treatment, such as negative air barriers. Following initial cleanup of the room, there were still higher asbestos levels than had been recorded prior to beginning the task. Twelve samples taken by nonaggressive methods were below the 10,000 fibers per cubic meter Environmental Protection Agency guideline. Of 12 samples taken by aggressive sampling, seven were above this limit. Several recommendations are made to improve glove bag efficacy, including improved work practices, improved wetting of lagging before removal using an injection technique, and use of glove bags supplied with negative air.
