Irritative Death from severe asthma in some sensitized subjects has been reported. by the provider may cause anxiety, particularly in children, system or eyes. Isocyanate compounds can irritate the eyes and skin and are not water soluble so they can be difficult to remove, so exposure prevention is very important. Double-bag Increased rates spasms may occur in immediate response to exposure. Provide supplemental oxygen if cardiopulmonary Because of their relatively larger surface Consult with the base station physician Peak excretion occurs at the end of exposure and the initial elimination half-life is 2 h for TDI and for HDI and IPDI suggesting end of exposure urine sample collection for biological monitoring of exposure [6,12,13]. exposures to methyl isocyanate occur primarily in occupational reproductive and developmental consequences. you might be legally required to file a report; contact your other complications, use the lowest amount of PEEP possible . There is no antidote for methyl isocyanate.
