In response to a request from a management representative of the Xomox Corporation (SIC-3491), Cincinnati, Ohio, a study was undertaken to evaluate exposures to workers using a polyurethane foam system in the shipping department. Xomox manufactured industrial valves, and the foam was used as a packaging material for shipping some types of valves. The foam contained 4,4'- diphenylmethane-diisocyanate (101688) (MDI) and polymethylenepolyphenyl-isocyanate (9016879) (MDI prepolymer) and was applied with a spray gun. All of the time weighted average air samples measured nondetectable levels of MDI and MDI prepolymer. Short term exposure samples did measure substantial levels of MDI ranging up to 320 micrograms/cubic meter of air. Two of the seven samples taken were above the OSHA ceiling limit of 200 micrograms/cubic meter. The author concludes that a health hazard existed from short term exposure to MDI. The author recommends that the use of the polyurethane foam system should be eliminated or proper engineering controls and personal protective equipment should be used to protect the workers.
