Abstract
Occupational exposure to methylene-chloride (75092) was studied. An industrial hygiene survey was conducted at Robins Air Force Base, Warner Robins, Georgia, to determine methylene-chloride concentrations. Breathing zone samples were collected from 12 of 22 aircraft stripping workers using charcoal tubes attached to sampling pumps for 6.5 to 7 hours. Ammonia (7664417) area samples were also collected. The range of methylene-chloride exposure concentrations was 15.7 to 268 parts per million (ppm), with an average concentration of 64ppm. The highest exposure concentrations was for the paint stripper personnel working on the aircraft wheel well (a single sample exceeded 200ppm). Ammonia concentrations ranged from less than 1ppm to 5.6ppm, with an average concentration of 3.2ppm. The authors conclude that although measurable amounts of methylene- chloride exist in the paint stripping facility, the time weighted average exposure of workers was below the OSHA standard of 500ppm. The sample exceeding 200ppm was due to inadequate ventilation in the wheel well of the aircraft.
