Lessons from an isocyanate tragedy

This paper highlights the features of prevention of isocyanate-induced occupational asthma from various angles: the employer, the employee, as well as the occupational physician entrusted with the care of such occupationally-exposed group of workers. The difficulties posed by the variability of the presentation, not least because of the relatively long latency, as well as the sensitising nature of the hazard, are discussed.
