AWR-111-W. What color triage tag is assigned to patients who are dead or lack spontaneous respirations after an airway is opened? Because it contains arsenic, lewisite has some effects that are similar to arsenic poisoning, including stomach ailments and low blood pressure. Lewisite is diagnosed by recognizing its clinical manifestations (immediate pain or irritation of skin and mucous membranes). Liquid exposure primarily damages the skin, producing an initial rash followed by blistering similar to a partial-thickness burn. Signs and Symptoms of Exposure.-The vapors of arsenicals are so irritating that conscious persons are immediately warned by discomfort to put on the mask. Early signs and symptoms will subside rapidly and allow the casualty to carry on with his combat mission if needed. It can be distinguished from mustards by the immediate pain upon contact, since, unlike mustards, lewisite has no latency period. This blistering compound is a light-to dark-brown liquid that vaporizes slowly. Of these, mustard is the one of most concern due to the delay in the onset of recognizable symptoms, the small amount of agent needed to cause tissue damage, and the resulting systemic damage which can result in death.
