• 300mg-min/m³ for resting person

• 1-10 minutes to effect

• Respiratory LCT50: 400mg-min/m³

• 10-15 minutes to effect

• Other Data

GA (Sarin)

• 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

GB (Sarin)

• Threshold eye effects 1mg-min/m³

• Respiratory lCt50 (mild): 15mg-min/m³

• 1-10 minutes to effect

• 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

• Rate of detoxification: Low, essentially cumulative

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:

• - Flush eyes with vapor immediately

• - 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)

• - Use steam and ammonia or hot soapy water in confined area

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
