Abstract
Exposures to epoxy resin were investigated in the summer of 1982 and 1983 at R and S Manufacturing Company (SIC-3621), Columbia, Pennsylvania. Evaluation was requested by an employee on behalf of 190 workers concerned about symptoms of dizziness, chills, fever, joint weakness, and back pain. Air samples were collected and analyzed for trimellitic-anhydride (552307) (TMA), epichlorohydrin (106898) (ECH), total dust, and silica (14808607). Sixteen epoxy room workers completed medical examinations and symptoms questionnaires. Breathing zone TMA concentrations ranged from 0.12 to 0.28 milligrams per cubic meter; no OSHA standard exists, but NIOSH recommends exposures be kept to the lowest feasible limit. None of the samples contained ECH or silica. Total dust concentrations were not reported. Four workers reported an irritant syndrome, three reported a late respiratory systemic syndrome, one reported a combination of both syndromes, and one reported an asthmatic rhinitis syndrome. Three females had peripheral neuropathy in the hand and nine had signs of burns on the forearms and hands. The authors conclude that a TMA exposure hazard previously existed; however, TMA is no longer used as part of the resin system. They recommend proper sizing and padding of the tongs to eliminate nerve compression, thermal insulating gloves, and housekeeping improvements.
