Abstract
Environmental and personal air samples were analyzed for lead (7439921), iron (7439896), manganese (7439965), nickel (7440020), cadmium (7440439), vanadium (7440622), chromium (7440473), copper (7440508), hydrazine (302012), methylene-chloride (75092), methanol (67561), 2-nitropropane (79469), toluene (108883), benzene (71432), xylene (1330207), dichlorobenzene (25321226), perchlorethylene (127184), and 1,1,1-trichloroethane (71556) at the METRO Bus Maintenance Shop (SIC-4171) in Washington, D.C., on January 22 to 23, 1981. An unidentified individual requested the evaluation on behalf of an unspecified number of workers. One of three nickel samples exceeded the NIOSH recommended standard of 0.015 milligrams per cubic meter. All other substances sampled were below their corresponding environmental standards. The authors conclude that workers at this facility may be at an increased risk of exposure to excessive airborne concentrations of nickel. They recommend consistent use of the spray booths increasing air velocity in the spray booths and welding hoods, and closing of the degreasing room doors.
