CHEMICAL WEAPONS CHEMICAL WEAPONS

The term chemical weapon is applied to any toxic chemical that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action.

Phosgene (COCl2)and mustard gas(C4H8Cl2S) are mostly used as a chemical weapon.

Phosgene gas was responsible for about 85% of the 100,000 deaths caused by chemical weapons.

Mustard gas was first used effectively in World War I by the German army against British and Canadian soldiers.

TYPES OF CHEMICAL WEAPONS

Types of Chemical Weapons

• Nerve Agents• Blister Agents• Blood Agents• Choking Agents• Incapacitating Agents

Nerve Agents

• Nerve agents attack the bodies nervous system. • Nerve agents cause breathing difficulties,

convulsions, paralysis, and death. • Nerve agents can be inhaled or absorbed

through the skin. • Symptoms poisoning include runny nose,

tightness of chest, difficulty breathing, excessive sweating, nausea, vomiting dimness of vision, and death.

• Example: soman

Blister Agents

• Blister agents attack the lungs, eyes, and skin. • They blister both skin and mucous

membranes. Example: Lewisite

Blood Agents

• Blood agents interfere with the bodies ability to absorb oxygen.

• The victim dies because the body tissues are starved of oxygen.

• Blood agents cause headaches and nausea before death.

Example: hydrogen cyanide.

Choking Agents

• Choking agents attack the lungs, causing them to fill with fluid. Choking agents are detected by their smell.

• The victim suffocates by drowning in his own body fluid. Choking agents cause coughing, choking, tightness of the chest, nasea, headache, and watering of the eyes.

• Examples: phosgene, chlorine.

Incapatitating Agents

• An agent that produces temporary physiological or mantal effects, or both, which will render individuals incapable of concerted effort in the performance of their assigned duties.

Casualities : temporary loss of vision, diarrhea etc.
