In which operating zone would responders be expected to conduct direct intervention at an incident?

In the context of incident response, the Restricted (Hot) zone is the area where responders engage directly with hazards, such as in the case of vehicle or machinery extrications. This zone is often characterized by immediate dangers, necessitating the highest level of protective equipment and training.

Operating in the Hot zone requires responders to have advanced planning, specialized knowledge, and the necessary tools to mitigate risks while performing interventions where potential threats such as fire, hazardous materials, or unstable structures may be present. It is within this zone that direct interventions are critical, whether it be rescuing trapped individuals, stabilizing equipment, or addressing threats to safety.

In contrast, the Limited Access (Warm) zone serves as a buffer between the Hot and Cold zones, where responders may prepare and establish operational plans without engaging in direct intervention. The Support (Cold) zone is designated for the staging of resources and personnel not engaged in the direct response to threats. General Access refers to areas freely accessible to the public and typically does not involve direct incident operations. Thus, the Restricted (Hot) zone is the only area where direct intervention is expected and necessary.
