Methyl Isocyanate : Clinical Effects<br />

• Dermal/ocular<br />

– Irritation and ulceration<br />

• Respiratory<br />

– Mucosal irritation <strong>of</strong> upper and lower respiratory tract<br />

– Life-threatening pulmonary edema<br />

– Residual chronic lung disease<br />

• Reactive Airways Dysfunction Syndrome (RADS)<br />

Module One – Toxic Industrial Gases as Terrorist Threats<br />

The clinical effects <strong>of</strong> methyl isocyanate predominantly involve 3 organ systems: skin<br />

(dermal), eyes (ocular) and lungs (respiratory). In each <strong>of</strong> these cases, methyl<br />

isocyanate acts as a potent irritant. Although the eye and skin manifestations may cause<br />

significant discom<strong>for</strong>t and distress and chronic disability, the life threatening effects<br />

occur from the pulmonary effects. A chemical pneumonia and pulmonary edema may<br />

result causing decreased oxygenation and air hunger. Overwhelming pulmonary<br />

compromise may result in death.<br />

RADS is a chronic pulmonary problem that may develop after an acute exposure to MIC.<br />
