Abstract
A preliminary survey of control technology for asbestos (1332214) removal (SIC-1799) was conducted at the Veterans Administration Hospital, Denver, Colorado in August, 1984. Wet removal methods were observed. Engineering controls consisted of an exhaust system that removed 500 cubic feet of air per minute from the work area, maintaining it under a negative pressure, a three module, mobile detoxification unit, and a water proof, portable fluorescent work drop light. It appeared that placement of the exhaust system and replacement air inlet was not optimized to obtain maximum dust control. Monitoring showed asbestos concentrations of less than 2 fibers per cubic centimeter (cc) inside the work area and 0.005 fiber/cc outside the work area. Proper showering techniques were followed by all workers observed. All workers in controlled (work) area wore contamination control disposable coveralls and half face mask respirators with high efficiency dust cartridges. Worker wearing of respiratory protection was well monitored. The author concludes that asbestos removal activities of the contractor seem to be well planned and executed. Further studies to optimize the use of exhaust systems are recommended.
