Final answer:
Chemical irritants cause temporary discomfort like skin redness and eye burning, which can be relieved with simple first aid measures. In contrast, more dangerous chemical agents like nerve agents can cause severe poisoning, requiring full protective gear to prevent absorption through the skin or inhalation.
Step-by-step explanation:
Chemical agents that irritate the skin, eyes, and mucous membranes but are not lethal are typically referred to as irritants. These agents, such as hydrogen peroxide, cause temporary discomfort and include household products that can induce irritation upon contact. However, unlike corrosive substances like strong acids or bases, irritants do not cause permanent tissue damage on brief exposure.
When it comes to more severe types of chemical agents, such as those used in chemical warfare, the effects are far more dangerous and can be life-threatening. Chemical warfare agents are classified based on how they affect the body, for instance, nerve agents like Sarin and VX, which can lead to severe poisoning. Contact with these agents can result in serious symptoms, including muscle paralysis and respiratory failure that can lead to death.
The question is "Explain about the chemical agents are classified as non-lethal and normally only irritate the skin, eyes, and inside of the mouth."
