NIOSH 1983 Mar:13 pages
In response to a request from the Allegheny County Health Department, an evaluation was made of polychlorinated-biphenyl (1336363) (PCB) exposure at Swissvale Auto Surplus Parts, Inc., (SIC- 5093), Pittsburgh, Pennsylvania. Work had been done at this facility some years earlier on scrap transformers and the transformer oil, which contained some PCBs was stored in inappropriately labeled drums. An attempt was made to burn a portion of this oil for heating purposes. Bulk samples of soil, soot, and dirt from the scrap yard were analyzed for PCBs, polychlorinated-dibenzodioxins (PCDDs), and polychlorinated- dibenzofurans (PCDFs). Wipe samples were taken from the hands of workers and various work surfaces and hand held tools. PCB isomers were detected at levels from 0.2 to 25 parts per million (ppm) per isomer in five of the six bulk samples. A soil sample taken near the storage area also contained PCBs. PCB concentrations on workers' hands ranged from 8.0 to 190 nanograms per square centimeter (ng/cm2). Surface PCB concentrations on a bathroom sink and on the handle of a hand held chipping power tool were 18 and 100ng/cm2, respectively. Blood samples from two of five scrap yard workers showed Aroclor-1254 (11097691) at 14 parts per billion (ppb) in one and Aroclor-1260 (11096825) at 11ppb in the other. The authors conclude that a hazard exists from surface and soil contamination with PCBs, although excessive PCB absorption was not seen in current workers. The authors recommend that some attempt be made to clean up the facility. Workers should be provided with suitable protective clothing for work involving possible contact with oils and chemicals. A clean wash area should be provided with provision for separate storage of home and work clothes. Eating, drinking and smoking in the scrap yard should be discouraged.
