In response to a request from the Allied Industrial Workers of America, a health hazard evaluation was conducted at Scott Molders (SIC-3089), Kent, Ohio regarding ergonomic concerns and potential exposures to ammonia (7664417), fibrous-glass (14808607), formaldehyde (50000), phenol (108952), and styrene (100425). The company employed about 70 workers in molding plastic and fibrous- glass parts of automotive, military and custom order clients. Workers were observed and videotaped in the molding and finishing areas. The major upper extremity stressors of these jobs were postural and muscular force demands which occur while performing the following task elements: unloading parts from molding machines and breaking or cutting off the excess plastic from parts; filing, reaming and sanding flashing from parts; reaching to activate press control buttons; and reaching to dispense completed parts into boxes or barrels. A general ergonomic risk factor for all workers was prolonged standing. Eight of 21 workers gave histories consistent with cumulative trauma disorders, and four had undergone surgery for chronic carpal tunnel syndrome. All air quality readings taken indicated that the levels of fibrous glass molding materials and other chemicals were within acceptable limits. The authors conclude that there were exposures to several postural and muscular force stressors. There were no overexposures to the chemicals. The authors recommend redesigning several work areas to minimize ergonomic stressors and reduce exposure to the chemical substances.
