| Studies have indicated that exposure to substances containing free isocyanate monomers present some health hazards when protective clothing is not worn. |
| Biological monitoring of isocyanate is possible using albumin adducts and their corresponding diamines in plasma and urine. |
| The single worst industrial accident in history occurred on December 3, 1984 when some 45 tons of the dangerous gas methyl isocyanate escaped from the Union Carbide plant in, India. |
| The two liquid precursors of a polyurethane are a multifunctional isocyanate and a prepolymer, a low-molecular-weight polyether or polyester bearing a multiplicity of reactive end-groups such as hydroxyl, amine, or amide. |
| Polyurethane foam is formed by mixing an organic polyol and an isocyanate along with amine or organometal catalysts and a fluorocarbon blowing agent. |
| The selection of the appropriate protective clothing will depend on a number of factors such as the type of paint, isocyanate exposure, how concentrated they are and environmental conditions such as ventilation. |
