GA (Tabum) Chemical and Physical Properties
GA (Tabum)
GA (Sarin) Nerve agent Enters body primarily through respiratory tract, but also can enter through skin and digestive trace Symptoms: Difficulty breathing, drooling, sweating, nausea, vomiting, cramps, jerking, staggering, involuntary defecation and urination, twitching, headache, confusion, drowsiness, coma, convulsions, death Treatment: Use of nerve agent antidote (atropine and 2-PAM chloride); pretreatment with pyridostigmine bromide (PB) increase survivability when antidote is used after exposure
GB (Sarin) Threshold eye effects 1mg-min/m³ Respiratory lCt50 (mild): 15mg-min/m³ Respiratory lCt50 : 55mg-min/m³ Respiratory LCT50: 100mg-min/m³ for resting person 2-15 minutes to effect Percutaneous lCt50: 8,000mg-min/m³ Percutaneous LD50: 12,000mg-min/m³ 2-15 minutes to effect

GB (Sarin) Physical state: Colorless liquid Odor: Almost none when pure Boiling point: 220° to 246°c at 760 mm HG Freezing point: -56 °C Flash point: Nonflammable Heat of vaporization: 80 cal/g Volatility: 22,000 mg/m³ at 25°C Decomposition temp: Complete decomposition after 2 1/2 hours at 150°C Stability in storage: Fairly stable in steel containers at 65°. Stability improves with increasing purity Molecular weight: 162.13
GB (Sarin) Means of detection in the field: - M18A2, M256A1 and M8A1 alarms - M8 and M9 paper Protection required: MOPP 4 - Clothing gives off G-agents for approximately 30 minutes after contact with vapor Decontamination: - Use M258A1, M258 or M291 skin decontaminating kit for liquid agent - Decontaminate equipment using calcium hypochlorite (HTH), Super tropical bleach (STB), household bleach, caustic soda, dilute alkali solutions, or decontaminating solution number 2 (DS2)
GD (Soman) Nerve agent Primary usage: Quick-action casualty agent Enters body primarily through respiratory tract, but also can enter through skin and digestive trace Symptoms: Difficulty breathing, drooling, sweating, nausea, vomiting, cramps, jerking, staggering, involuntary defecation and urination, twitching, headache, confusion, drowsiness, coma, convulsions, death Treatment: Use of nerve agent antidote (atropine and 2-PAM chloride); pretreatment with pyridostigmine bromide (PB) increase survivability when antidote is used after exposure to nerve agent; after a few minutes antidotes are not as effective for GD poisoning as they are for other nerve agents
GD (Soman) Threshold eye effects 0.16mg-min/m³ Respiratory lCt50 : 25mg-min/m³ 1-10 minutes to effect Respiratory LCt50 : 70mg-min/m³ 1-15 minutes to effect Percutaneous LCt50: 10,000mg-min/m³ Rate of detoxification: Low, essentially cumulative
