Nerve, blister, blood, choking, and irritating agents are classified under which category?

The classification of nerve, blister, blood, choking, and irritating agents falls under chemical agents due to their nature and effects. Chemical agents are substances that can cause harm to human health through various pathways, primarily by disrupting normal physiological functions.

Nerve agents, such as sarin and VX, disrupt the normal functioning of the nervous system. Blister agents, like mustard gas, cause severe damage to the skin and respiratory tract. Blood agents, such as cyanide, interfere with the body’s ability to use oxygen. Choking agents, like chlorine gas, primarily affect the respiratory system, leading to difficulty in breathing. Irritating agents can cause symptoms like irritation to the eyes, skin, or respiratory tract.

This grouping is vital in understanding their potential use in warfare or terrorism, as they can inflict mass harm and require specific response protocols. Other categories mentioned, such as biological or radiological agents, refer to different types of threats that involve pathogens or radioactive materials rather than chemical substances. Therefore, recognizing these agents as chemical is essential for effective response and mitigation.
