CG, carbonyl chloride, Fosgeen, Fosgen, Koolstofoxychloride, Collongite, D-Stoff, Hosugen
Phosgene (CG) is known chemically as carbonyl chloride. It is the “starting” chemical for many products produced by the chemical industry. Phosgene is a colorless and highly toxic gas with a suffocating odor reminiscent of moldy hay. The vapors are strongly irritating to the eyes. Phosgene is an insidious poison since it does not irritate immediately even when fatal concentrations are inhaled. It affects solely the lungs and results in damage to the capillaries. In extreme cases, the membranes swell and the lungs become filled with fluid (pulmonary edema). Death usually results from lack of oxygen.
