Vesicants and nerve agents are in the same hazard class.

Vesicants and nerve agents are in the same hazard class.

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Hazard classifications group chemicals by their primary health hazard, and both vesicants (blister agents) and nerve agents are considered extremely toxic substances. That places them in the same hazard class, Class 6: Toxic Substances. They differ in the specific effects and mechanisms—nerve agents disrupt the nervous system by inhibiting acetylcholinesterase, while vesicants cause severe skin and mucous membrane damage—yet both are categorized under the same toxic-substance class due to their high potential to cause serious harm. So the statement is true.
