In response to a request from the Electronic Components Division of the GTE Products Corporation (SIC-3674), Williamsport, Pennsylvania, an evaluation was made of possible hazardous working conditions resulting from exposure to rosin pyrolysis products, Freon (75456), methylene-chloride (75092), and other chemicals. Workers in the Standard Electronic Module (SEM) assembly and testing area reported dizziness; headache; eye, nose and throat irritation; memory loss and mood changes. Air sampling was conducted for formaldehyde (50000), total aldehydes, carbon-dioxide (124389) (CO2) and carbon- monoxide (630080). Formaldehyde and total aldehydes were below the limits of detection. CO2 concentrations in the solder touchup and wave solder areas ranged from 600 to 1200 parts per million (ppm), suggesting deficiencies in the ventilation system. Medical interviews were conducted with 23 workers; many reported symptoms consistent with exposure to agents with neurotoxic and irritant characteristics. The authors conclude that a potential health hazard existed from inadequate ventilation; chemicals used in the area are capable of precipitating symptoms reported by workers. The authors recommend that measures be taken to reduce or eliminate exposures to methylene-chloride, improve housekeeping and ventilation, and institute medical surveillance. Industrial hygiene monitoring should be continued, and recirculation of exhaust air from the SEM areas should be stopped.
