Phosgene Oxime (CX)

• Means of detection in the field:

• - M18A2, M256A1 and M8 alarms

• Protection required: MOPP 4

• Decontamination:

• - Use large amounts of water

• - Because of the rapid reaction of CX with the skin, decontamination will not be effective after pain occurs

• - Nevertheless, decontaminate as rapidly as posible by flushing the area with large amounts of water to remove any agent that has not reacted with the skin

Phosgene (CG)

• Choking agent

• Primary usage: Delayed -action casualty agent

• Enters body through respiratory tract

• Very small dosages of phosgene are extremely corrosive to lung tissue

• Symptoms: Initially only minor irritation to the eyes and throat; after latent period of 4-8 hours, discoloration of the lips, break out in a cold, sticky, sweat, long lasting lesions on lung, quantities of fluid escape from bloodstream into lungs, literally drowning the victim who dies from a lack of oxygen

Phosgene (CG)

• lCt50: 1,600 mg-min/m³

• 3-12 hours to effect during which time lungs are filling with fluid)

• LCt50: 3,200mg-min/m³

• 3-24 hours to effect (during which time lungs are filling with liquid)

• Rate of detoxification: Not detoxified, cumulative

Phosgene (CG)

• Physical state: Colorless gas

• Odor: New mown grass or hay

• Boiling point: 7.6°C at 760 mm

• Freezing point: -128°C

• Flash point: N/A

• Heat of vaporization: 59 cal/g at

• Volatility: 4,300,000 mg/m³ at 7.6°C, 2,200,000mg/m³ at -10°C, 528,000mg/m³ at -40°C,

• Decomposition temp: 800°C

• Stability in storage: Stable in steel containers if CG is dry

• Molecular weight: 98.92

Phosgene (CG)

• Means of detection in the field:

• - M18A2

• Protection required: Protective mask

• Decontamination:

• - Confined areas, aeration

• - Not required in the field

• Persistency

• -Short; vapor may persist for some time in low places under calm or light winds and stable atmospheric conditions ( approximately 30 minutes in summer; and 3 hours at -20 degrees

Diphosgene (DP)

• Choking agent

• Primary usage: Delayed-action casualty

• Enters primarily through respiratory tract

• Symptoms: Initially only minor irritation to eyes and throat; after latent period of 4-8 hours, discoloration of the lips, breaking out in a cold, sticky sweat, systemic damage, especially to liver and kidneys, long lasting lesions on lungs develop, quantities of fluid escape from bloodstream into lungs, literally drowning the victim who dies from a lack of oxygen.

• Those who survive may suffer trauma and suddenly expire, or they may suffer after effects in the following years

Diphosgene (DP)

• lCt50: 1,600mg-min/m³

• 3-12 hours to effect (during which lungs are filling up with fluid)

• LCt50: 3,200mg-min/m³

• 3-24 hours to effect (during which lungs are filling with fluid)

• Detoxification Rate: Not detoxified, cumulative

Diphosgene (DP)

• Physical state: Colorless gas

• Odor: New-mown hay, grass, corn

• Boiling point: 127°C at 760 mm HG

• Freezing point: 57°

• Volatility: 12,000 mg/m³ at 0°C, 45,0000 mg/m³ at 20°C, 270,000 mg/m³ at 51.7 °C

• Decomposition temp: 300°C

• Stability in storage: Only stable in glass

• Molecular weight: 197.85

Diphosgene (DP)

• Means of detection in the field:

• - M18A2, Odor

• Protection required:

• -Protective mask

• Decontamination:
