Abstract
In response to a request from the EPA, the risk of exposure of workers at G-and-L Recovery Systems Incorporated (SIC-9999), Ashtabula, Ohio to volatile organic chemicals was investigated. The company had been authorized by the EPA to develop alternative methods for the disposal of transformers containing polychlorinated biphenyls (PCBs). The facility employed seven workers. Average breathing zone exposure levels to trichloroethylene (79016) (TCE) ranged from 5.3 to 11.8 parts per million (ppm) during an initial survey and from 20.8 to 29.2ppm during followup. The highest average levels were seen in decontamination technicians; however, stripper technicians had the highest personal TCE exposures. Average personal exposures to PCBs ranged from 14.5 to 20.8 micrograms/cubic meter initially and from 9.9 to 25.9 micrograms/cubic meter at followup. Decontamination and stripper technicians again demonstrated the highest exposure levels. All but two high contact surfaces outside of the containment area had PCB levels near or greater than 100 micrograms/square meter. In the production area, surface PCB levels ranged from 1,000 to 72,000 micrograms/square meter. High surface and area air levels of polychlorinated-dibenzo-p-dioxins and polychlorinated-dibenzo-p- difurans were identified, as were increased serum PCB levels in workers. The authors conclude that a hazard existed from exposures to TCE and PCBs.
