Description:Concentrations of alpha-pinene, beta-pinene and primaric acids were measured on February 5 to 9, 1978, and pulmonary function tests of workers were conducted on February 6 to 10, 1978 at the Champion Building Products (SIC-2435) in Bonner, Montana. The Lumber and Sawmill Workers L.P.I.W. Local Union 3038, Missoula, Montana requested the evaluation to determine the potential exposure to plywood veneer dryer emissions for 475 affected workers. Total acid concentrations ranged up to 2.5 milligrams per cubic meter (mg/m3). Pinene concentrations ranged from 0.55 to 14.13mg/m3. No environmental standards exist for these substances. Common medical complaints were upper respiratory irritation, dry throats, stuffy nose, running nose, coughing, burning or itching eyes, chest tightness or wheezing. Pulmonary function tests did not reveal any significant impairments among the workers. The authors conclude that no significant health hazard exists for workers at this facility. They recommended that door seals on veneer dryers be cleaned and repaired to prevent leakage, shroud be placed over both feeder and offbear ends with feeders positioned outside the shroud, and roof ventilators consist of exhaust fans inside the shrouded areas. Exhaust emissions should not be permitted to reenter the same or other work areas. Pre-assignment and periodic medical examinations for workers also are recommended, along with employee education on the irritant effects produced by veneer dryer emissions.
