Phosgene Oxime - CX

Field protection Protective mask and permeable protective clothing for vapor and small droplets impermeable protective clothing for protection against large droplets, splashes, and smears. 

Decontamination HTH, STB, household bleach, DS2, or caustic soda. Decontaminate liquid agent on the skin with the M258A1, M258, or M291 skin decontaminating kit. Decontaminate individual equipment with the M280 individual equipment decontamination kit. 

Persistency Depends on munitions used and the weather. Somewhat shorter that that of HD under dry conditions short duration when wet. (Heavily splashed liquid HD persists 1-2 days under average weather conditions, and a week or more under very cold conditions.) 

CX is an urticant, producing instant, almost intolerable pain and local tissue destruction immediately on contact with skin and mucous membranes. It is toxic through inhalation, skin and eye exposure, and ingestion. Its rate of detoxification in the body is unknown. 

Appearance Colorless solid or liquid CX may appear as a colorless, low melting point (below 39°C, crystalline) solid or as a liquid above 39°C. It has a high vapor pressure, slowly decomposes at normal temperatures.

Blister agents Also known as vesicants, these are chemical weapon compounds that cause severe blistering of the skin, as well as damage to the eyes, mucous membranes, respiratory tract and internal organs. This class of chemical weapon agent includes the arsenicals/Lewisites (L), phosgene oxime (CX), and sulfur mustards (HD, HN).
