Vesicant (blistering) agents primarily expose victims via the skin, leading to which primary effect?

• A. Blistering at the exposure site
• B. Respiratory distress
• C. Nausea
• D. Dizziness

Answer: (A)

Vesicants damage skin cells that are actively dividing, so when they contact the skin, the most prominent and immediate effect is the formation of blisters at the site of exposure. This blistering occurs as the epidermal and dermal layers separate and fluid-filled vesicles develop, reflecting direct dermal injury from the agent. Respiratory distress, nausea, or dizziness can occur if the agent is inhaled or absorbed systemically, but the hallmark result of skin exposure is blistering right where contact occurred. In practice, rapid decontamination is essential to limit further skin injury and spread.
