If exposure to skin occurs, treat symptomatically as for contact dermatitis or thermal burns. If burned, treat as thermal burns. MDI is also a known pulmonary sensitizer. Treatment is essentially symptomatic. An individual having a skin or pulmonary sensitization reaction to this material should be removed from further exposure to any isocyanate.
Dense smoke is emitted when product is burned without sufficient oxygen.
MDI vapor and other gases may be generated by thermal decomposition. F accelerate the reaction of MDI with water, which releases carbon dioxide. Explosive rupture of closed containers is possible. Hazardous Combustion Products Decomposition products include isocyanate vapor and mist, carbon dioxide, carbon monoxide, nitrogen oxide, and traces of hydrogen cyanide. For large scale fires, alcohol-resistant foams are preferred, if available.
