Title Risk associated with the spray application of polyurethane foam
Bibliographic information Sep. 1981, Vol.42, No.9, p.663-665. 14 ref.
Abstract Exposure to isocyanate vapour and to dust and overspray of polyurethane foam was evaluated using personal and area sampling at sites where insulating foam was applied by spraying in confined spaces. Exposure to tolylene diisocyanate vapour was frequently ≥ 0.08ppm for personal samples and 0.148ppm for area samples. Organic vapour cartridge respirators used by the sprayers were covered with overspray. Helpers used protective plastic bags over the head which posed an oxygen-starvation hazard. Workers' necks, faces, hair and clothing were contaminated with polyurethane particles and dust. Recommendations are made for reductions of significant health hazards existing at these work sites.
