Health hazard evaluation report: HETA-90-198-L2060, Gencorp Polymer Products, Mogadore, Ohio.
In response to a request from the International Chemical Workers Union, a visit was made to Gencorp Polymer Products in Mogadore, Ohio to evaluate possible hazardous working conditions at this site, particularly worker exposure to styrene (100425) and 1,3-butadiene (106990) monomers used in the production of styrene-butadiene latex. An industrial hygiene walk through inspection, air sampling, a review of industrial hygiene and environmental data collected by the company, and private interview with employees were conducted. There was no evidence of styrene exposures that would exceed the NIOSH recommended Exposure Limit of 50 parts per million (ppm) or other standards. Short term exposures to 1,3-butadiene were documented and found to be unlikely to exceed the ACGIH Threshold Limit Value of 10ppm. The authors conclude that there is little potential for worker exposures to styrene or 1,3-butadiene. Because the NIOSH recommendation for 1,3-butadiene states that the exposures are to be limited to the lowest possible amount, recommendations for minimizing these exposures even further are offered.
