The primary route of exposure for vesicant (blistering) agents is which route?

• A. Skin
• B. Inhalation
• C. Ingestion
• D. Eye

Answer: (A)

Exposure to vesicant agents most commonly affects the skin because these liquids readily remain on and penetrate the skin, causing the characteristic deep tissue injury that leads to blistering. The skin’s large surface area and the agent’s propensity to bind and damage epidermal cells over time make dermal contact the usual route of exposure. Eye and inhalation injuries are serious and possible, but they are less likely to be the initial or primary route compared to skin contact. Ingestion is not a typical delivery method for vesicants. Rapid decontamination—carefully removing contaminated clothing and washing the skin—greatly reduces blistering by limiting how long and how much agent remains in contact with the skin.
