A walk through survey was made at Westinghouse Electric Corporation, Sharon, Pennsylvania for the purpose of determining the extent of worker exposure to various chemicals, including polychlorinated- biphenyls (1336363) (PCB) in the transformer production area. Air samples were collected to evaluate solvent exposures. Approximately 20 of the 3100 employees were involved in PCB operations. The personal air samples ranged from a concentration of 9.5 to 69.7 micrograms/cubic meter while the area air samples ranged from 28.4 to 56.7 micrograms/cubic meter for PCB. No concentrations of benzene, butyl acetate, ethyl-acetate, or methyl-ethyl-ketone were detected. One sample registered a xylene (1330207) concentration of author recommends that all operations involving PCB use should be carried out in a room with a negative ventilation system or outdoors. Local exhaust ventilation, protective clothing and organic vapor respirators should be used for work with PCBs. PCB contaminated material should be disposed of in appropriate containers and sent to an appropriate disposal site. The process has since been shut down.
