• Description:
  A preliminary survey of control technology for asbestos (1332214) removal (SIC-1799) at Gateway High School, Aurora, Colorado was conducted in August, 1984. Operations involved removing sprayed on asbestos fire proofing on the ceiling and overhead beams. A portable, modular airlock, shower, and dressing facility was utilized to ensure proper clean up of workers following work at the removal site. Plastic barriers were constructed to form a material staging area and walk tunnel between the decontamination unit and the work areas. An exhaust unit was used to maintain a negative pressure in the containment area. The walls were washed down before being ripped out. Workers in the rip out area wore half face respirators with high efficiency dust filters, disposable coveralls, special shoe coverings, and head covers. Work was deliberate and workers used care to assure the material was thoroughly wetted before scraping it into plastic bags. As little material as possible was allowed to fall. Contractor monitoring showed background airborne asbestos concentrations on the order of 0.002 fiber per cubic centimeter. The author concludes that this asbestos removal operation represents one of the better work practice/dust control procedures observed to date.
