• Description:
  A walk through survey of control technology for asbestos (1332214) removal (SIC-1799) was conducted at Columbus East High School, Columbus, Indiana in July, 1984. Dry removal from a high bay ceiling and beams was observed. Although the containment barrier control method recommended by the Environmental Protection Agency was employed on the project, it was not being used where active removal was in progress. A filtration unit was operating within the enclosure to reduce airborne asbestos fiber concentrations by recirculating filtered air; however, it did not provide negative pressure control or dilution of air. Work activity was hindered by the necessity to position work platforms between a metal angle iron ceiling grid. Asbestos material scraped from the ceiling was allowed to fall to the floor to be cleaned up later. Polarized contrast microscopy was used to monitor worker exposure. Exposure records showed asbestos fibers being consistently controlled to be below 2.0 fibers per cubic centimeter in all work areas. Removal workers wore disposable coveralls and half face cartridge respirators. Decontamination showers were located at the entrance to the enclosure. The author notes that the on site industrial hygiene control system compares favorably with others observed.
