Which type of Chemical Warfare Agent (CWA) is known to cause skin burns and blisters?

Blister agents are a category of chemical warfare agents specifically known for their ability to cause severe injuries to the skin, eyes, and respiratory system. When these agents come into contact with the skin, they can lead to painful burns and the formation of blisters. Examples of blister agents include substances like mustard gas and lewisite, which can not only cause immediate discomfort but can also have long-term health effects.

The designation of blister agents emphasizes their characteristic effects, which are distinct from those caused by other categories of chemical agents. Nerve agents, for instance, primarily disrupt the nervous system and can lead to paralysis or death but do not typically cause burns or blistering. Choking agents cause respiratory distress and are designed to incapacitate individuals by affecting lung function. Blood agents, on the other hand, interfere with the body’s ability to utilize oxygen but do not result in skin injuries.

Therefore, blister agents stand out clearly for their specific impact on the skin, making them the correct choice for identifying the type of chemical warfare agent known for causing skin burns and blisters.
