What are vesicants also known as?

1. Corrosive agents

2. Blister agents

3. Gas agents

4. Combustible agents

The correct answer is: Blister agents

Vesicants are commonly referred to as blister agents because they have the capability to cause severe blistering of the skin and mucous membranes upon exposure. This is a characteristic trait of vesicants; they primarily act as chemical agents that inflict damage to the tissue, leading to the formation of blisters. This effect can occur even at lower levels of exposure, making them particularly hazardous in chemical warfare and hazardous material situations. The term "blister agent" effectively captures the primary consequence of exposure to these substances, which is the painful and debilitating formation of blisters. Understanding the impact of vesicants is critical for those training in hazardous materials response, as it influences how protective measures, decontamination procedures, and medical responses are implemented during incidents involving these types of chemicals.
