Which of the following is NOT a primary class of chemical agents?

• A. Nerve agents
• B. Blister agents
• C. Choking agents
• D. Radiological agents

Answer: (D)

Radiological agents do not fall under the primary classes of chemical agents. The primary classes of chemical agents are traditionally classified into three categories: nerve agents, blister agents, and choking agents. Nerve agents, such as sarin or VX, disrupt the normal functioning of the nervous system, leading to respiratory failure and potentially death. Blister agents, like mustard gas, cause severe damage to skin and mucous membranes, leading to painful blisters and systemic toxicity. Choking agents, such as chlorine and phosgene, cause damage to the respiratory system, leading to suffocation and severe pulmonary injuries. In contrast, radiological agents pertain to materials that emit radiation, and they are part of a different category altogether that includes biological and nuclear hazards. While they pose significant threats and are a concern in terms of defense and emergency response, they are not classified as chemical agents. This distinction is crucial for understanding the different types of threats and the specific defensive measures that may be required for each class.
