Boiling point: 129°C at 760 mm HG(with decomposition) Freezing point: 35°- 40°C Flash point: N/A Heat of vaporization: 101 cal/g at 40°C Volatility: 1,800 mg/m³ at 20°C, 76,0000 mg/m³ at 40°C, Decomposition temp: Below 128°C Stability in storage: Extremely unstable in presence of traces of metal or other impurities, even traces of iron chloride may cause explosion. Pure material is stable only for one to two months in glass vessels at 20°C, and is most stable in aromatic solvents Molecular weight: 113.9
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 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: - 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 Molecular weight: 197.85
Diphosgene (DP) Means of detection in the field: - M18A2, Odor 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
Arsine (SA) Choking agent Primary usage: Delayed-action casualty agent
