Environmental and personal air samples were analyzed for toxic concentrations of methylene-dianiline (101779), methylene-bis-(4- cyclohexylisocyanate), methylene-chloride (75092), and 1,1,1- trichloroethane (71556) at the General Electric Company (SIC-3573) in Waynesboro, Virginia, on May 7, 1975. Exposures of plating room employees to airborne concentrations of nitric-acid (12507776), cyanides, hydrochloric-acid (7647010), sodium-hydroxide (1310732), nickel (7440020), chromium (7440473) and trichloroethylene (79016) were also studied. No samples revealed toxic concentrations of any chemicals in question. The author recommends that the ventilation system be evaluated, routine monitoring for industrial hygiene be conducted, and employee training be improved.
