Following a request from the International Association of Machinists, Lodge 1933, breathing zone air samples were evaluated and 187 of 493 workers were interviewed concerning health problems at the FMC Corporation (SIC-2819), Pocatello, Idaho. Carbon- monoxide (630080) concentrations ranged from 1 to 9.5 parts per million (ppm). Respirable quartz (14808607) concentrations ranged from 0.28 to 5.71 milligrams/cubic meter (mg/m3). Seven of nine total quartz dust samples exceeded the criterion of 3.75mg/m3. Phosphorus (7723140) concentrations ranged from less than 0.023 to occurred in the furnace area and ranged from 0.01ppm to 1.24ppm. Phosphine (7803512) concentrations were less than 0.1ppm. Of workers interviewed, 47.6 percent described possibly work related health problems, including respiratory tract problems, skin irritation, and back problems; 34 percent reported minor phosphorus burns. Dental problems correlated with work in the phosphorus department. The authors conclude that workers are potentially exposed to excessive airborne concentrations of respirable and total quartz dust and sulfur-dioxide. The potential exists for harmful exposures to phosphorus, phosphine, hot surfaces and liquids, but medical, dental and environmental programs appear to address these problems. Respiratory protection is recommended for jobs involving potential exposures.
