Vesicants or blister agents such as nitrogen mustard are classified as which hazard class?

• A. 3.1
• B. 2.3
• C. 6.1
• D. 4.1

Answer: (C)

Vesicants are classified as toxic substances because their primary danger to people is toxicity from exposure, especially to skin, eyes, and the respiratory tract. In hazmat terms, the class that covers chemicals that can cause harm through contact or inhalation is the toxic substances category, and blister agents like nitrogen mustard fit there due to their severe toxic effects. They are not primarily an explosive hazard, not mainly a toxic gas hazard, and not a flammable solid hazard, which would be the focus if those properties were the dominant risk. So the appropriate hazard class for vesicants is the toxic substances category.
