Which CBRNE category includes agents that cause rapid skin destruction and blisters?

• A. Vesicants
• B. Radiological
• C. Biological
• D. Nerve

Answer: (A)

Vesicants are blistering chemical agents that attack skin tissues, causing rapid destruction and the appearance of blisters. When skin is exposed, cells in the epidermis and underlying layers are damaged, leading to pain, redness, swelling, and the quick development of large fluid-filled blisters. The onset can be minutes to hours after exposure, and the tissue damage can extend beyond the surface, making wound healing challenging. These agents can contaminate surfaces and linger in the environment, so immediate decontamination is crucial—removing contaminated clothing and thoroughly washing the skin and any exposed mucous membranes to limit absorption. There is no antidote; management focuses on rapid decontamination, meticulous wound care, pain control, infection prevention, and monitoring for complications. Other CBRNE categories involve different mechanisms and timelines. Radiological injuries stem from ionizing radiation and have a distinct pattern of tissue damage, not the characteristic rapid blistering of vesicants. Biological agents cause infections or toxin-mediated illness with onset that varies and often systemic involvement. Nerve agents produce rapid neurotoxic effects, with muscarinic and nicotinic symptoms, rather than primary skin blistering.
