In response to a request from Polymer Engineering, Inc. (SIC-3079), Reynolds, Indiana, an evaluation was made of possible hazardous working during the manufacture of thermoset microwave cookware and custom molded plastic parts. The facility employed about 150 production workers. Particular attention was given to exposure to styrene (100425) in the Compounding Department. In this department the primary constituents of the plastics were weighed, mixed, blended, extruded, and placed in crates for transport to the Pressing Department. The highest personal time weighted average exposures were analyzed and indicated a mean exposure level of 44.6 parts per million (ppm). There were exposure levels for each of the three extruder operators which exceeded the 50.0ppm NIOSH Recommended Exposure Limit. Short term personal exposures in the Compounding Department ranged from 26.6 to 39.1ppm. Total dust exposures ranged from 1.0 to 12.3mg/m3 throughout the facility. Personal samples in the Compounding Department showed exposures at 12.3mg/m3. The authors conclude that a health hazard existed from styrene and nuisance dust exposures. The authors recommend changes in the ventilation system, installation of local exhaust ventilation at the extruder operations, and enclosure of the preweigh station.
