Abstract
A preliminary survey of the Bell Lumber and Pole Company (SIC-2491) in New Brighton, Minnesota, was conducted on June 27, 1979. Process methods, potential or known exposure conditions, and test sampling methods were assessed to determine if a comprehensive investigation was needed to evaluate long term health effects associated with wood preserving. Fifteen of 27 employees at the facility treat utility poles with pentachlorophenol (87865) (PCP) using a nonpressure thermal process. Employee training and work practices, the occupational educational program, historical data, and results of safety and health monitoring were evaluated. General air sampling was conducted during regular operations at sites of potential exposure in order to evaluate different air sampling methods, define analytical limitations, and obtain a range of exposure levels during critical short term tasks. PCP concentrations were measured at 0.13 to 0.36 milligrams per cubic meter (mg/m3) using a NIOSH procedure, and 0.27 to 1.33mg/m3 using a silica gel method. Airborne levels of PCP over a treatment tank decreased during the afternoon sampling period, possibly due to wind effects. The authors conclude that differences in results using the NIOSH procedure and the silica gel method could not be explained adequately because of the limited data obtained.
