摘要: Environmental and personal air samples were analyzed for the presence of ozone (10028156), fluorides, nitrogen dioxide (10102440), iron oxide, manganese (7439965), chromium (7440473), total fume, naphtha (8030306), isobutyl isobut... 展开 Environmental and personal air samples were analyzed for the presence of ozone (10028156), fluorides, nitrogen dioxide (10102440), iron oxide, manganese (7439965), chromium (7440473), total fume, naphtha (8030306), isobutyl isobutyrate (97858), methyl-n-butyl ketone (591786), isobutyl acetate (110190), isobutyl alcohol (78831), toluene (108883), xylene (1330207), hydrochloric acid (7647010), hexavalent chromium (7440473), cadmium (7440439), cyanide (57125), 1,1,1-trichloroethane (71556), and asbestos (1332214) at the Cissel Manufacturing Company (SIC-3582) in Louisville, Kentucky during July 1978 and January 1979. An evaluation request came from an authorized representative of an unspecified number of employees. Only concentrations of asbestos, ranging from 0.19 to 0.30 fibers per cubic centimeter, exceeded the recommended exposure limit of 0.1 fibers per cubic centimeter. Inadequate ventilation and work practices also were noted. The author concludes that a potential health hazard did exist for workers exposed to asbestos. They recommend measures to reduce employee asbestos exposures, improve exhaust ventilation and institute better work practices. 收起
