As part of an industry wide evaluation of worker exposure to wood preservative chemicals, industrial hygiene studies were conducted at 12 wood treating facilities and two manufacturing operations. Airborne exposure levels were determined and work practices were characterized at each of these locations. Over 1000 such facilities exist in the United States with the majority of them having less than ten workers involved in the wood treatment process. About ten major facilities produce about half the treated wood. Employee exposure to the chemicals was in general well below the recommended limits. During certain tasks such as cylinder opening and unloading, filling nonpressure tanks with hot oil solutions, and during the inspection of treated wood inside the nonpressure treatment tank, short term peak exposures occurred. Even so, these exposures were also below the recommended limits. Recommendations were made to reduce the exposure levels even further by limiting employee exposure during emergency spills, nonroutine situations or critical process tasks. The authors recommend the use of personal protective equipment, modified work practices, and medical surveillance programs.
