In response to a request from the Amalgamated Clothing and Textile Workers Union, an evaluation was made of potential hazards existing at Janesville Products (SIC-2531), Brodhead, Wisconsin. Particular attention was given to toluene-diisocyanate (584849) (TDI), methylene-bisphenyl-isocyanate (101688) (MDI), and methylene- chloride (75092) exposures. This facility was involved in the production of polyurethane foams, particularly seats for the automotive industry. TDI concentrations in personal breathing samples ranged from not detectable to 0.001 parts per million (ppm). Area air samples in the repair room showed TDI ranging from 0.004 to 0.006ppm. MDI was not detectable in any sample. Methylene- chloride concentrations in the ceiling ranged from 5.8 to 399ppm. Time weighted average values for long term samples of methylene- chloride ranged from 4.7 to 39.5ppm. The repair area showed carbon- monoxide (630080) concentrations of about 25ppm. Shortness of breath was reported by 34 percent of the interviewed employees. Pulmonary function tests were within the normal range for all individuals tested. A decrease in Forced Expiratory Volume in 1 second of over 10 percent was noted among three employees over the course of their shift. The mean blood carbon-monoxide levels were 2.53 percent before and 2.67 percent following the shift. The authors conclude that a potential toxic exposure to the combined effects of methylene-chloride and carbon-monoxide was alleviated through engineering controls. The authors recommend specific measures to control exposures, including measures concerning personal hygiene, work practices, health and safety programs, the ventilation system, personal protective equipment, medical surveillance, and exposure monitoring.
