Abstract
Environmental and medical surveys were conducted on December 14, 1977, April 18 to 20, 1978, and May 18, 1978, to evaluate employee exposure to potentially toxic substances at Chilton Metal Products (SIC-3291) in Chilton, Wisconsin. The evaluation was requested by an authorized employee representative on behalf of the 300 affected employees. Carbon-monoxide (630080) concentrations ranged from 41 to 118 parts per million (ppm) for short term detectors and from 25 to 106ppm for long term detectors, exceeding the 50ppm OSHA standard. Chlorodifluoromethane (75456) (Freon-22) concentrations ranged from 2,906 to 3,146ppm, exceeding the American Conference of Governmental Industrial Hygienist standard of 1,000ppm. All other environmental samples were below their respective criteria. The author concludes that workers are exposed to hazardous concentrations of carbon-monoxide. The Freon-22 concentrations present a potential exposure hazard. The author recommends that exposure to carbon-monoxide be reduced through conversion of gasoline powered lift trucks to low pressure gas or the use of catalytic converters, that the ventilation system be modified, that an exhaust ventilation system be completed at the bottled gas filling apparatus, and that present exhaust ventilation systems be changed.
