Title Toluene diisocyanate exposures in the flexible polyurethane foam industry
Bibliographic information June 1987, Vol.48, No.6, p.580-585. Illus. 14 ref.
Abstract A 3-year survey of toluene diisocyanate exposure in 2 flexible polyurethane foam manufacturing facilities was conducted. The geometric mean time-weighted average exposures were 2.36ppb, 1.10ppb, and 1.50ppb for the foam line workers, finishing workers and maintenance personnel, respectively. The OSHA ceiling standard of 20ppb was exceeded by 1.3% of the short-term (12min) exposure measurements taken. Exposures were predominantly to the 2,6 isomer of TDI.
