A vesicant is defined as a substance that can produce blistering upon direct contact with the skin or mucous membranes. This blistering occurs due to the chemical effects of the vesicant, which can cause irritation and damage to the outer layers of the skin. Vesicants are often used in a medical context to describe certain chemicals that can lead to tissue injury, and their effects can be quite severe, sometimes requiring medical intervention.

In a clinical or dental setting, understanding the nature of vesicants is crucial, as they can pose a risk if not handled properly. Training and awareness about these substances help prevent accidental exposure and ensure appropriate safety protocols are followed.
