Title Airborne methlyene diphenyl diisocyanate (MDI) concentrations associated with the application of polyurethane spray foam in residential construction
Bibliographic information Feb. 2007, Vol.4, No.2, p.145-155. Illus. 14 ref.
Abstract The objective of this study was to evaluate the exposure to airborne methylene diphenyl diisocyanate (MDI) among spray polyurethane foam applicators. It was conducted during foam application inside five single family homes under construction in the United States and Canada. Spray foam applicators and assistants may be exposed to airborne MDI concentrations above the OSHA permissible exposure limit of 0.20mg/m3, ceiling. At these concentrations, OSHA recommends appropriate respiratory protection. Airborne MDI concentrations decrease rapidly after foam application ceases. The majority of the airborne MDI samples collected in the breathing zones of the spray foam applicators exceeded the OSHA PEL-C. The highest airborne concentrations measured after 15 and 45min were 0.019mg/m3 and 0.003mg/m3, respectively. Other findings are discussed.
