Distilled Mustard is classified as which type of agent?

Distilled mustard, commonly known as mustard gas, is classified as a blister agent. This classification is due to its ability to cause painful blisters and severe skin irritation upon exposure. Mustard gas damages the skin and mucous membranes, leading to significant chemical burns, which can result in long-term health complications.

Additionally, blister agents like mustard gas work primarily by causing tissue damage through chemical reactions rather than through effects on the nervous system, blood, or respiratory systems. Therefore, its specific function and impact on the human body align closely with the characteristics of blister agents, making this the correct classification.
