NIOSH 1979 Sep:14 pages
The Missouri Wood Treating Company (SIC-2491) of Raymondsville, Missouri was surveyed on July 11, 1979 to provide information on the company's current and past process methods, review occupational safety and health procedures, determine exposure concentrations of pentachlorophenol (87865) (PCP) during routine treatment processes, assess air sampling methods, and collect information for future criteria documentation or technical reports on the wood preservative industry. Six employees had potential routine exposure to the PCP in light oil which is used in a vacuum impregnation process to preserve soft and hard wood lumber. The company had no formal medical surveillance, industrial hygiene, or safety program for its employees at the time of the survey. Safety equipment was limited primarily to leather gloves used for handling treated lumber. Company management reported no history of medical problems arising from the work process. Area air monitoring performed with the NIOSH impinger method indicated airborne PCP concentrations of 0.13 to absorption method indicated that all PCP concentrations were below provided significantly different results, which suggested a poor correlation between procedures. However, too few samples were collected to evaluate the difference adequately.
