Phosgene oxime (CX) falls under which category of chemical agents?

Phosgene oxime (CX) is categorized as a blister agent due to its ability to cause severe chemical burns, particularly on the skin and in respiratory tissues. Blister agents are designed to damage human tissue, leading to painful blisters and significant long-term health effects. This characteristic aligns with the primary effects of phosgene oxime, which can lead to extensive suffering and require immediate medical intervention.

In contrast, nerve agents disrupt the nervous system, incapacitating agents are typically intended to incapacitate without direct lethal effects, and choking agents primarily affect the respiratory system, causing symptoms such as coughing and choking sensations. Understanding these distinctions reinforces the classification of phosgene oxime as a blister agent, highlighting its detrimental impact on bodily tissues and the necessity for effective protective measures during potential exposure.
