What action should the ISO take if a responder is exhausted and overheated at a plane crash scene?

Ensuring that the responder is able to rest and rehydrate at the rehab area is crucial in managing their health and safety at a plane crash scene. When responders are exposed to the physical and psychological stresses associated with such incidents, they can become exhausted and overheated. This can significantly impair their ability to perform necessary rescue and recovery operations effectively.

The rehabilitation area serves as a designated space where responders can rest, receive medical evaluations, hydrate, and cool down, thus helping to prevent heat-related illnesses and maintain operational effectiveness. Allowing responders to recover ensures they can return to the scene refreshed and capable of safely carrying out their responsibilities. This proactive approach is essential for maintaining the well-being of the team and sustaining the incident response effort.

Other options, while relevant to various situations in incident management, do not directly address the immediate need for the responder's physical recovery and safety in this context.
