Area and breathing zone samples were analyzed for styrene (100425) at Air Plastics, Incorporated (SIC-3079), Cincinnati, Ohio in June 1984. Engineering controls and work practices in the filament winding process were investigated. Breathing zone styrene concentrations ranged from 180 to 300 parts per million (ppm) and an area sample at an exhaust fan had a concentration of 400ppm. The OSHA standard for peak styrene exposure is 200ppm. The filament winding operation used dilution for control of any air contaminants. Exhaust fans were located in the walls behind the winding stations. The workers positioned themselves upwind of the product during spraying and roll out. This had been determined to be the best position for avoiding back spray during the operation. The company had purchased detector tube kits for monitoring styrene exposure. Employees in the spray and roll out operations wore protective goggles and half mask respirators. Employees in fiberglass cutting and grinding operations wore nuisance dust respirators. The authors recommend installation of an oil free compressor as a source of breathing air and installation of partitions around each winding mandrel.
