What is a "chemical warfare agent" in the context of hazardous materials?

A chemical warfare agent is defined as a toxic chemical that is specifically designed to cause harm or death to individuals during armed conflict. These agents can affect the body in various ways, leading to incapacitation or fatal health issues, making them potent tools of warfare.

Understanding this definition highlights the context of their use: they are not intended for any benign purpose, such as agricultural practices, environmental protection, or exclusive industrial applications, which separate them from the other choices provided. This clarity about the intent and application of chemical warfare agents underscores the significance of their categorization in hazardous materials management and response planning.
