Definition & Operational Usage
A hazardous materials incident refers to an event characterized by the uncontrolled release of hazardous substances, which can significantly threaten public health, safety, and the environment. Such incidents may include chemical spills, leaks, or explosions and necessitate the implementation of specialized response protocols, including the establishment of Hot, Warm, and Cold Zones. Not to be confused with routine spills, these incidents require immediate coordination through systems like the Incident Command System (ICS) and adherence to National Incident Management System (NIMS) principles.
