What are sulfur mustard and Lewisite examples of?

Sulfur mustard and Lewisite are classified as blister agents, which are chemicals that cause severe blisters on exposed skin and mucous membranes. Upon contact, these agents can lead to painful injuries, damage to internal tissues, and long-lasting health effects. The mechanism of action for blister agents involves the disruption of cellular function and integrity, leading to necrosis of the affected areas.

Compared to other categories of chemical agents, blister agents specifically target the skin and respiratory system, causing immediate and often severe medical implications. This is distinct from choking agents, which irritate the respiratory system; nerve agents, which disrupt the nervous system; and incapacitating agents, which are designed to impair an individual’s ability to function without necessarily causing death or severe injury. Understanding the specific nature and effects of sulfur mustard and Lewisite helps emergency responders and military personnel recognize the symptoms and respond appropriately in scenarios involving these hazardous materials.
