Technical Assistance Report No. TA 80-48, Chemical Recovery Systems, Inc., Elyria, Ohio

摘要

Environmental and personal air samples were analyzed for the presence of organic vapors, and explosion measurements were taken on April 23 and 24, 1980, at Chemical Recovery Systems, Inc. (SIC-2842), Elyria, Ohio. An evaluation request came from the U.S. Environmental Protection Agency Office of Enforcement, Hazardous Waste Enforcement Task Force on behalf of an unspecified number of workers. Time weighted average concentrations ranged from 9.6 to 28.4 parts per million (ppm) for acetone; 1.9 to 4.5ppm for 1,1,1-trichloroethane, 3.0 to 37.1ppm for methylene chloride; 0.5 to 19.6ppm for toluene; and 0.3 to 5.6 for xylene. None of these chemical concentrations exceeded their respective OSHA permissible exposure limits of 1000, 350, 100, 100 and 100ppm. No explosive mixtures were detected. The author concludes that no health hazards associated with exposure to organic solvents or explosives exist at this facility. He recommends that chemical drums be properly stacked and stored.
