What is a hot zone in emergency response?

In emergency response, a hot zone refers to a dangerous location where the risk of harm is present, often identified during hazardous materials incidents, or situations involving active threats. This area is characterized by significant dangers, including exposure to harmful substances, physical violence, or other threats that require urgent attention from responders.

Establishing a hot zone allows emergency personnel to clearly define where the immediate hazards are, thereby ensuring that those who do not have the appropriate training or equipment do not inadvertently enter this area. Being aware of hot zones is crucial for the safety of both responders and the public, preventing exposure to harm by delineating areas that require specialized intervention before the situation can be safely managed.
