What is the first step in assessing a rescue situation?

The first step in assessing a rescue situation involves performing a scene size-up to evaluate hazards and the condition of the victim. This critical initial assessment helps rescuers gather essential information about the environment and any potential dangers that could impact the safety of both the victim and the rescuers. By understanding the location, the water's conditions, and the surrounding environment, rescuers can develop an effective plan for the rescue, prioritize safety, and determine the necessary resources.

Assessing the victim's health is certainly important, but it occurs after the scene size-up. Immediate entry into the water without assessing the situation can lead to additional risks for both the rescuer and the victim. Calling for backup is also crucial, but this typically follows the initial assessment when more information is available. Thus, the correct initial step is to conduct a thorough evaluation of the scene to ensure a safe and effective response.
