Original title Asthme retardé au diphénylméthane-diisocyanate (MDI). [in French]

Abstract See CIS 72-2260 for a case study (Lob M.) on delayed asthma with fever due to this substance. The present article gives a more recent similar case study (following exposure while welding polyurethane belts) and 3 others which turned up in the course of an investigation in the various plants where these belts were used. In all these cases the workers concerned had been exposed to fumes given off during welding of the belts, using a hot plate. The fumes did not contain tolylene diisocyanate. Follows a review of the pyrolysis of polyurethanes and theories on the mechanism of respiratory disorders due to diisocyanates, emphasing the hazards of inhalation tests and the importance of occupational anamnesis in the case studies described.
