Mustard (HD), Nitrogen mustard (HN), and Lewisite (L) are classified as what type of agents?

Mustard (HD), Nitrogen mustard (HN), and Lewisite (L) are classified as blister agents. These agents are specifically designed to cause severe blisters and damage to the skin and respiratory tract upon exposure.

Blister agents work by producing chemical burns and blisters on contact with skin, and they can also damage internal organs if inhaled or absorbed. For example, mustard gas can lead to symptoms that include painful blisters, severe respiratory distress, and damage to the eyes, potentially resulting in blindness. Lewisite adds further toxic properties, being a dark, oily compound that can cause similar effects.

Understanding the classification of these agents is crucial for military personnel and first responders, as it influences both the protective measures required and the treatments necessary in case of exposure.
