Abstract
Worker exposures to veneer dryer emissions were surveyed on September 24 to 26, 1981 at Louisiana-Pacific (SIC-2435) in Mellen, Wisconsin. Evaluation was requested by the International Woodworkers of America, Local 4-335, for 68 workers. Air samples were analyzed for alpha-pinene (80568), beta-pinene (127913), abietec-acid (514103), pimaric-acid (127275), and tannic-acid (1401554). Drying area workers completed preshift and postshift medical symptom questionnaires. During oak drying, mean concentrations of pinenes, abietic-acid, primaric-acid, and tannic- acid were 0.10, 0.014, 0.014, and 0.013 milligrams per cubic meter (mg/m3), respectively. During pine drying, respective mean concentrations of pinenes, abietic-acid, and primaric-acid were 1.47, 7.0, and 0.034mg/m3. Tannic-acid does not occur in pine wood. No exposure standards exist for any of the test agents. Among the 68 workers, 28 reported eye, nose and throat irritation during oak drying operations. Symptom frequency was less during pine drying operations. The authors conclude that exposure to veneer emissions can cause mild, short term irritation symptoms in workers. They recommend elimination of potential leak areas as well as medical monitoring and education of exposed workers.
