Asphyxiant/Blood - Arsine
- Cyanogen chloride
- Hydrogen cyanide
- Possible cherry red skin
- Possible cyanosis

- Chlorine is a greenish yellow gas with pungent odor
- Phosgene gas smells like newly mown hay or grass
- Possible frostbite*
- Eye and skin irritation
- Airway irritation
- Dyspnea, cough

- Nitrogen mustard (HN-1, HN-2,HN-3)
- Lewisite (L)
- Phosgene oxime (CX)
- Mustard (HD) has an odor like burning garlic or horseradish
- Lewisite (L) has an odor like penetrating geranium
- Phosgene oxime (CX) has a pepperish or pungent odor
- Severe irritation
- Redness and blisters of the skin
- Tearing, conjunctivitis, corneal damage
- Mild respiratory distress to marked airway damage
- May cause death
Incapacitating/ Behavior-altering - Agent 15/BZ - May appear as mass drug intoxication with erratic behaviors, shared realistic and distinct hallucinations, disrobing and confusion
- Hyperthermia
- Mydriasis (dilated pupils)
- Dry mouth and skin
- Initial tachycardia
- Altered consciousness, delusions, denial of illness, belligerence
- Hyperthermia
- Ataxia (lack of coordination)
- Hallucinations
- Mydriasis (dilated pupils)
*Frostbite may occur from skin contact with liquid arsine, cyanogen chloride or phosgene.
