In NBC classification, which category includes Sarin, Mustard, and Tabun?

• A. Biological
• B. Radiological
• C. Nuclear
• D. Chemical

Answer: (D)

Hazard classification in NBC focuses on Nuclear, Biological, or Chemical hazards. Sarin, Mustard, and Tabun are chemical warfare agents, which is why the Chemical category fits them best. They are manufactured chemicals that cause harm through chemical reactions in the body (nerve disruption with Sarin and Tabun; skin and tissue damage with Mustard), not living organisms or their toxins (Biological), and not radioactive materials or radiation sources (Radiological/Nuclear). In practice, chemical hazards are identified by their toxic effects and physical forms (gas, vapor, or liquid) and require chemical-specific PPE, decontamination, and detection approaches, distinct from those used for biological or radiological/nuclear hazards.
