What is a mustard gas considered to be?

• A. Mutagen
• B. Vesicant
• C. Neurotoxin
• D. Irritant

Answer: (A)

Mustard gas is best described as a vesicant, a blistering agent. Its defining effect is the formation of painful blisters on the skin and mucous membranes, with potential injury to the eyes and respiratory tract. The blistering can be delayed, which makes decontamination and medical care challenging. It does have DNA-alkylating properties that can contribute to mutagenicity and carcinogenic risk, but the primary emergency response classification is vesicant. It is not a neurotoxin, and it goes beyond simple irritation because it causes deep tissue damage and blister formation rather than just surface irritation.
