The comments of Dr. Naseri Esfahani were well received. The exposure to 2,4-diisocyanate (TDI) gas was a work accident. The patient had been working in the same work position since 18 months earlier, from the very beginning of his work. The exposure had happened indoors. Although the patient had been doing the same task in the same area for almost 18 months, on the time of accident, he was exposed to a massive amount of TDI after a break in the gas tank, as it was fully described in our Report.
