In the NBC classification, nerve agents are categorized as which type?

• A. Choking agents
• B. Blood agents
• C. Chemical
• D. Biological

Answer: (C)

Nerve agents are chemical hazards in the NBC framework. They’re synthetic chemicals designed to disrupt the nervous system, not infectious organisms or radiological materials. Their action is chemical—specifically, they inhibit acetylcholinesterase, leading to excessive nerve signaling and rapid, life-threatening symptoms. Choking and blood agents are other chemical subtypes, but nerve agents themselves fall under the chemical category. Biological would involve living organisms or toxins from living sources, which isn’t the case here.
