Use

Diphenylchlorarsine (Clark I) is a white crystalline solid which melts at 45 degrees C (113 degrees F). When dispersed from a munition, it forms a dust that will penetrate charcoal canisters. If inhaled, it caused irritation to the upper respiratory tract, the peripheral nerves and the eyes. The lungs are also affected and the victim experiences acute chest pain, shortness of breath and nausea which leads to retching and severe vomiting.
