Which class are vesicants and nerve agents in?

• A. 6.1
• B. 6.2
• C. 3.1
• D. 2.3

Answer: (A)

Vesicants and nerve agents are toxic chemical hazards, so they belong in Class 6.1: Toxic Substances. This category covers poisonous chemical agents regardless of their physical state, including blister agents and nerve agents. The infectious-substances category is Class 6.2 and covers biological materials, not chemical warfare agents. The other classes shown correspond to different hazard types (for example, Class 3 is flammable liquids and Class 2.3 is toxic gases), which don’t apply here.
