Health hazard evaluation report: HETA-84-533-1565, Long Island Rail Road, Jamaica, New York.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HETA 84-533-1565, 1985 Mar; :1-10
Environmental samples were analyzed for polychlorinated biphenyls (PCBs) at an electrical repair shop (SIC-7629) of the Long Island Railroad, Jamaica, New york in November, 1984 and January, 1985. The evaluation was requested by the Safety Department of the railroad and the Electrical Union because of concern for possible PCB exposure while energizing capacitors in the inverter/converters. During operation, smoke was released from defective capacitors. Wipe samples collected from surfaces of the inverter/converters and generator contained 12 to 35 micrograms per 100 square centimeters (microg/100cm2) Aroclor-1016 (12674112). Vacuum cleaner dust also contained 87microg/gram Aroclor-1016. The NIOSH recommended standard for PCB contaminated surfaces is 0.5microg/100cm2. After the Safety Department was informed of the evaluation results, the railroad took such actions as identifying the capacitors that contained PCBs, replacing these with other capacitors, and decontaminating the generator. The charging operation was reinspected. The author concludes that there was a potential hazard from skin contact with PCBs in the electrical repair shop. Based on the reinspection, vacuum cleaner replacement and installation of an exhaust ventilated cover for the inverter/converters is recommended.
