Why is the assessment of the surroundings important before rescue efforts begin?

The assessment of the surroundings before beginning rescue efforts is crucial for identifying risks that may affect the operation. This involves looking for potential hazards such as downed power lines, leaking fuel, unstable debris, or traffic on surrounding roads that could pose dangers to both rescuers and victims. By thoroughly evaluating the environment, rescuers can develop an effective plan that prioritizes safety and enables them to execute their tasks without exposing themselves or others to unnecessary danger. This proactive approach ensures that the rescue can be carried out efficiently while minimizing the risks involved.
