Abstract
Worker exposures during the manufacture of electronic resistors were surveyed on December 20 and 21, 1983 at Dale Electronics Corporation (SIC-3676) in Yankton, South Dakota. The evaluation was requested by company management on behalf of about 300 workers. Personal and area air samples were collected for various work process chemicals, including toluene-diisocyanate (26471625) (TDI), several organic solvents, mercury (7439976), lead (7439921), and fluorides. Exposures to TDI, lead, and mercury were well below the respective OSHA limits of 140, 50, and 100 micrograms per cubic meter, respectively. No significant exposures were found for solvents, either individually or combined. The author concludes that workers are not exposed to any significant chemical hazards at this factory, and recommends the use of good work practices and protective gloves to prevent skin contact with chemicals used in the epoxy resin systems and polyurethane mixes. To further reduce TDI exposures and the risk of sensitization, a laboratory type hood with an exhaust volume of 150 cubic feet per minute for each square foot of door area should be installed in the polyurethane resin mixing area.
