Hygienic assessment of working conditions in the manufacture of polyurethane foam products

We studied working conditions in the production of polyurethane foam products for the automotive industry. Polyurethanes are synthesized by interaction of isocyanates with polyesters in the presence of stabilizers, catalysts, emulsifiers, foaming agents, colorants, etc. Of all compounds used, the most toxic are toluene diisocyanate (TDI), diphenylmethane diisocyanate (DMI) and the amines triethylenediamine, triethanolamine.
