The process of providing rest, rehydration, nourishment, and medical evaluation to responders who are involved in extended and/or extreme incident scene operations is defined as Emergency Incident Rehabilitation. The goal of rehab is to get firefighters either back into the action or back to the station in a safe and healthy condition. When rehab operations are implemented properly, they go a long way towards making sure that the physical and mental conditions of responders operating at the emergency scene do not deteriorate to a point that affects the safety of any responder or that jeopardizes the safety or effectiveness of incident operations.
