Isocyanates are chemicals that can cause occupational asthma, irritation of the skin, eyes, nose and throat, and cancer. Deaths have occurred due to both asthma and hypersensitivity pneumonitis from isocyanates exposure. Respiratory illnesses also can be caused by isocyanates exposure to the skin. Isocyanates are used in materials including paints, varnishes, auto body repair, and building insulation. Jobs that involve exposure to isocyanates include the spray-on polyurethane manufacturing of products such as mattresses and car seats, and protective coatings for truck beds, boats and decks.
