| - A pulmonary agent (or choking agent) is a chemical weapon agent designed to impede a victim's ability to breathe. They operate by causing a build-up of fluids in the lungs which then leads to suffocation. Exposure to the eyes and skin tend to be corrosive, causing blurred vision and severe deep burns. Inhalation of these agents cause burning of the throat, coughing, vomiting, headache, pain in chest, tightness in chest, and respiratory and circulatory failure. Examples of pulmonary agents include:

| - A pulmonary agent (or choking agent) is a chemical weapon agent designed to impede a victim's ability to breathe. They operate by causing a build-up of fluids in the lungs which then leads to suffocation. Exposure to the eyes and skin tend to be corrosive, causing blurred vision and severe deep burns. Inhalation of these agents cause burning of the throat, coughing, vomiting, headache, pain in chest, tightness in chest, and respiratory and circulatory failure. Examples of pulmonary agents include:
* Chlorine gas
* Chloropicrin (PS)
* Diphosgene (DP)
* Phosgene (CG)
* Disulfur decafluoride
* Perfluoroisobutene
* Acrolein
* Diphenylcyanoarsine Phosgene is the most dangerous commonly used pulmonary agent (although disulfur decafluoride and perfluoroisobutene are both even more dangerous, with respectively 4 and 10 times the lethality of phosgene, neither is widely used). It is a colorless gas under ordinary conditions. It has a vapor density 3.4 times greater than that of air, allowing it to remain low in the air for long periods of times. Phosgene leads to massive pulmonary edema, which reaches maximum symptoms in 12 hours after exposure, followed by death within 24–48 hours. Chlorine is an element used in industry. It is one of the most commonly manufactured chemicals in the United States. It is used to make pesticides, rubber, and solvents. It is also used in drinking water and swimming pools to kill bacteria. The extent of poisoning caused by chlorine depends on the amount of chlorine a person is exposed to.
