Definition & Operational Usage
A chemical agent is a specific type of hazardous substance that can adversely affect human health, animal life, or environmental integrity. These agents are categorized into various classes, including nerve agents, blister agents, and choking agents, each exhibiting unique mechanisms of action and physiological effects. Not to be confused with biological agents, which are derived from living organisms, chemical agents are often encountered in scenarios requiring adherence to protocols such as the Incident Command System (ICS) and the National Incident Management System (NIMS).
