Pulmonary agent

A pulmonary agent, or choking agent, is a chemical weapon agent designed to impede a victim's ability to breathe. Such compounds operate by causing a build-up of fluids in the lungs, which then leads to asphyxiation. Exposure of the eyes and skin tends to be corrosive, causing blurred vision and severe deep burns. Inhalation of these agents causes burning of the throat, coughing, vomiting, headache, pain in chest, tightness in chest, and respiratory and circulatory failure.
