Abstract
Environmental and breathing zone samples were analyzed for azodicarbonamide (123773), benzene (71432), styrene (100425), and toluene (108883) at Leon Plastics (SIC-3079), Grand Rapids, Michigan in March and May, 1983, and March, 1984. The evaluation was requested jointly by the union, the Michigan Department of Public Health, and a US Senator to investigate occupational exposures to chemical agents, particularly in the injection molding department where numerous worker compensation claims had been filed. Sixteen employees were interviewed. Azodicarbonamide concentrations ranged from undetectable to 280 micrograms per cubic meter (microg/m3) in May, 1983 and from undetectable to 752microg/m3 in March, 1984. There is no federal standard for azodicarbonamide. The concentrations of the other substances were below their relevant standards. Ammonia (7664417), styrene, and triphenylphosphate (115866) were identified as pyrolysis products above the azodicarbonamide presses. Symptoms of eye, nose and throat irritation, coughing, and wheezing were reported. Pulmonary function test results obtained by the University of Michigan could not be linked to azodicarbonamide exposures. The authors conclude that exposure to azodicarbonamide is the probable cause of the reported symptoms. Recommendations include using engineering controls and appropriate work practices to minimize exposure to azodicarbonamide.
