Environmental and medical health evaluation surveys were performed at the TRW electrical resistor manufacturing facility (SIC-3622) located in Philadelphia, Pa., via employee interviews, evaluation of ventilation systems, evaluation of work procedures and available toxicity information. The results obtained indicate that employee exposures to butyl-cellosolve (111762), ethyl-alcohol (64175), and xylene in the filament-draw department did not pose a health hazard at the concentrations measured during this evaluation. Employees may, however, be exposed to potentially toxic concentrations of mercury (7439976). Exposures to trichloroethylene (79016) in the lead-heading room do not constitute a health hazard. Workers in the mold department were not exposed to toxic concentrations of phenol (108952) or nuisance dust. Employees exposures to xylene (1330207), 1,1,1-trichloroethane (71556), methyl-ethyl-ketone (78933) and toluene (108883) in the sub-assembly area did not constitute a health hazard. The plating room operator was not exposed to toxic levels of lead (7439921) or fluorides. The medical program at this TRW facility appears to be adequate. The program adheres to the medical criteria as recommended by NIOSH criteria documents. Appropriate biological monitoring and medical surveillance are being done. Medical interviews with workers revealed no work related health complaints. A review of company medical records also produced no significant findings.
