Abstract
A site visit was made to a pentachlorophenol (87865) (PCP) production facility, Reichhold Chemicals Incorporated (SIC-2865), Tacoma, Washington, to investigate possible contamination of the PCP with polychlorinated dibenzo-p-dioxins and dibenzofurans. During the production process, PCP fumes and dust occurred at the small shaker screen, the bagger and the molding stations; dust and fumes were vented to a mold bag filter system. A total of 28 personal breathing zone samples were collected during 2 days of sampling. Two of the samples were above the 0.5mg/m3 time weighted average (TWA) permissible exposure limit for PCP. One was 1.65mg/m3 for an operator who was bagging prilled PCP. This individual wore a respirator so that his exposure was less. A maintenance man recorded a TWA of 0.68mg/m3, and he was not using safety equipment. Five bulk samples were also collected. It was not possible to measure dioxins in the personal breathing zone or area air samples. However, using the concentrations of PCP measured on the filter portion of the personal breathing zone samples, estimates were made for dioxins and furans. The authors conclude that workers at this facility are suitable for inclusion in the Dioxin Registry. The authors recommend that efforts should be undertaken to reduce the amount of dust generated during the PCP bagging operation. Dust which does escape should be vacuumed, not swept. Maintenance employees should follow the same safety practices as the workers.
