Environmental air samples were analyzed for toxic concentrations of wood dust, 1,1,1-trichloroethane (71556), and other chemical constituents of Lacquer thinner at the Northpark Millwork LTD, (SIC- 2851) Colorado Springs, Colorado on August 28 and 29, 1978. The evaluation request was made from an authorized representative of approximately 15 affected employees. Four of six samples for wood dust exceeded the evaluation criteria of 5 milligrams per cubic meter, while the average wood dust concentration was more than double the evaluation criteria. Although none of the samples for the Lacquer thinner vapors exceeded the evaluation criteria, the author concludes that the cabinet makers were exposed to potentially toxic concentrations of 1,1,1-trichloroethane and other Lacquer thinner constituents. Employees who worked with stationary power woodworking equipment were exposed to potentially toxic concentrations of wood dust. He recommends monitoring wood dust concentrations, various exhaust ventilation modifications and the use of respirators by appropriate workers, and other safety measures.
