Occupational asthma (OA) has been reported in workers exposed to anhydrides, isocyanates (TDI, MDI, HDI, IPDI, hydrogenated MDI), triglycidyl isocyanurate (TGIC) and aliphatic and cycloaliphatic amines (N,N-Dimethyl-1,3-propanediamine, ethylenediamine, triethylene tetramine, dimethylethanolamine, isophorone diamine, and hexamethylenetetramine). [Malo] Hypersensitivity pneumonitis (HP) may be caused by isocyanates and trimellitic anhydride.
