Surveys of occupational exposures to wood preservative chemicals were performed. Wood preservatives identified included creosotes (9002862), pentachlorophenol (87865) solutions, inorganic arsenical mixtures and a miscellaneous group. Methods of wood treatment, including air seasoning, kiln drying, steam and vacuum treating, and bouetonizing, were described. In addition, industrial hygiene studies were conducted in 11 wood treating facilities and two manufacturing operations. Airborne exposure levels were determined, and methods of exposure control were evaluated. With few exceptions, employee exposures to wood preservative chemicals were well below current standards for health risk. The authors suggest improved work practices to minimize exposures. Recommendations are given concerning protective equipment, and medical surveillance programs.
