Environmental and personal air samples were analyzed for the presence of 1,1,1-trichloroethane (71556) at the Pacific Power and Light Company (SIC-4911) in Rawlins, Wyoming on January 27, 1981. A representative of the Utility Workers Union of America, AFL-CIO, Local 127, requested the evaluation on behalf of an unspecified number of workers. Concentrations of 1,1,1-trichloroethane in environmental and personal samples ranged from 4 to 610 milligrams per cubic meter (mg/m3), compared with the OSHA standard of 1900mg/m3 for an 8 hour time weighted average exposure. The author concludes that a 1,1,1-trichloroethane exposure hazard did not exist at the time of the survey. He recommends that an environmental study be undertaken at this facility during the summer when larger quantities of 1,1,1-trichloroethane are used, a worker education program on 1,1,1-trichloroethane hazards be implemented, and appropriate personal hygiene practices be used.
