• Description:
  Harmful exposures to wood preserving chemicals were investigated at the Cascade Pole Company (SIC-2491) in Tacoma, Washington, on May 30, 1980. Approximately 18 employees worked in areas of potential exposure. Area air samples were collected from the tap of cylinder doors and during the opening of cylinders during ammoniacal-copper- arsenate (ACA) and chromated-copper-arsenate (CCA) processing. Air samples also were collected from the top of treated wood storage areas and wipe samples were collected from ACA and CCA processed woods. Samples were analyzed for copper (7440508) (Cu), creosote, pentachlorophenol (87865) (PCP), chrome (7440473) (Cr), and arsenic (7440382) (As). The company provided preemployment examinations and audiometric tests, but did not maintain a regular medical surveillance program. The employees were provided with safety equipment and participated in training and safety meetings. All air samples were undetectable for Cu, As, and PCP. Creosote concentrations at the cylinder and on treated wood were 3.94 and 2.12 milligrams per cubic meter, respectively, when measured gravimetrically and 0.66 and 9.71 milligrams per cubic meter, respectively, when measured by ultraviolet light. These high values were not found at worker stations. Wipe samples from CCA and ACA treated woods contained trace amounts of Cu, Cr and As ranging from 19 to 240 micrograms, with the highest concentrations found after ACA treatment. The authors conclude that the treated lumber presents a potential skin exposure problem which would be eliminated by wearing protective gloves.
