Phosgene
chemical formula COCl2, phosgene is a very toxic gas with a TLV of 0.1ppm. Phosgene has a moldy, hay like odor and is irritating. Phosgene is a reaction product that can form during chlorinated furnace cleans if sufficient oxygen isn't present.

Phosgene
Chemical warfare agent, Choking Agent
Phosgene, Others - irritate the alveoli in the lungs. This irritation causes the alveoli to constantly secrete fluid into the lungs. The lungs slowly fill with this fluid (which is called pulmonary edema), and the victim dies from lack of oxygen (also known as dry land drowning).
Description: Liquid dispersed in a liquid-filled shell that explodes, rapidly vaporizing as a low-lying, white cloud of gas. It has a characteristic odor of sweet, newly mown hay or freshly cut grass or corn.
Symptoms: After a latent period, the victim experiences worsening respiratory distress that at first is unaccompanied by signs of pulmonary damage but that may progress relentlessly to death. Irritation of the larynx by very large concentrations of the agent may lead to sudden laryngeal spasm and death. The most prominent symptom following the latent period is difficulty breathing, perceived as shortness of breath with or without chest tightness. Death results from respiratory failure or in combination with the effects of lack of oxygen to vital organs and tissues. Complications include infection of damaged lungs and delayed death following such respiratory infections.
Treatment: No antidote.
Protection: Protective mask, clothing.

Phosgene
This gas gained infamy as a chemical weapon during World War I, but it is also a valuable industrial reagent and building block in organic synthesis. It is colourless, but can appear as a white or yellowish haze when released into air, due to refraction of light. In low concentrations, its odor resembles recently cut hay or green corn (maize); at higher concentrations, it may be strongly unpleasant. In addition to its industrial production, small amounts occur naturally from the breakdown of chlorinated compounds and the combustion of chlorine-containing organic compounds.
