In response to a request from employees at the Aluminum Company of America (SIC-3354) facility in Lafayette, Indiana, an evaluation was made of potential exposure to polychlorinated-biphenyls (1336363) (PCBs) during the extrusion press operation. Hydraulic fluids used in the running of these presses contained PCBs. A group of 15 mechanics, electricians, and laborers serviced these presses. The hydraulic and coolant lines and pumps required maintenance both internally and below the presses where there was a series of catacombs containing the equipment. These areas were typically soaked with the hydraulic and coolant fluids. Concentrations of PCBs ranging from trace amounts to 2.0 micrograms/cubic meter (microg/m3) of air were detected in the environmental air samples. Surface concentrations ranged from trace levels to 900 micrograms/square meter. While some of these concentration levels exceeded the NIOSH recommended exposure limit (1.0microg/m3), serum PCB levels (nondetectable to 15.9 nanograms/milliliter) were not above those of the normal nonoccupationally exposed population. The author concludes that the levels of PCBs presents a potential hazard. The author recommends the use of personal protective clothing and decontamination of the area.
