Abstract
The Permapost Products Company of Hillsboro, Oregon was surveyed on June 25, 1979 to provide information on current and past process methods and materials used for treating wood products (SIC-2491), to review occupational safety and health procedures, determine exposure concentrations of pentachlorophenol (87865) (PCP), and collect information for future technical reports. Twenty employees were involved in the wood preserving processes which include treatment by copper-8-quinolinolate (10380286), chromated copper arsenate (37337136) (CCA), and PCP. The company had no formalized medical monitoring on industrial hygiene programs although annual audiometric tests were given and exposure was controlled through work practices, processing methods, and protective equipment. Both the NIOSH and silica gel methods for air monitoring revealed that airborne PCP concentrations were below the limit of detection inside the treatment building. Samples taken on top of the hot wood bundles removed from the treatment cylinder indicated that PCP concentrations were below 0.26 milligrams per cubic meter (mg/m3). Samples taken at a site near the cylinder when its door was opened indicated PCP concentrations of 0.51mg/m3 by the NIOSH method and comparative evaluation of the two monitoring methods cannot be made due to the small number of samples taken, and that three of the six samples had concentration below detection limits.
