What are the four major categories of chemical agents?

• A. Nerve, Blood, Blister, and Choking
• B. Flammable, Toxic, Corrosive, and Irritant
• C. Biological, Radiological, Chemical, and Thermal
• D. Acidic, Basic, Neutral, and Reactive

Answer: (A)

The four major categories of chemical agents are indeed classified as Nerve, Blood, Blister, and Choking agents. These categories represent distinct types of chemical weapons that cause harm through different mechanisms. Nerve agents disrupt the normal functioning of the nervous system, leading to symptoms such as muscle spasms, respiratory failure, and potentially death if exposure is severe enough. Blood agents, on the other hand, interfere with the body's ability to use oxygen, affecting the circulatory system and leading to asphyxiation. Blister agents cause severe skin, eye, and respiratory tract damage, resulting in painful blisters and long-term health effects. Choking agents primarily affect the respiratory system, leading to coughing, choking, and the potential for pulmonary edema. This classification of chemical agents is crucial for training and preparedness in CBR defense, as each type requires specific protective measures and treatment protocols following exposure. Other options, while mentioning important characteristics of substances or different types of threats, do not accurately represent the formal categories of chemical agents as defined in chemical warfare classifications.
