What should First Responders prioritize during a scene size-up?

During a scene size-up, the primary focus for First Responders is on identifying and mitigating hazards. This step is crucial to ensure the safety of both the responders and any individuals involved in the incident. By assessing the scene and recognizing potential dangers—such as fire, hazardous materials, unstable structures, or crowd control issues—responders can take necessary precautions before engaging further. This proactive approach allows them to devise strategies that prioritize safety, minimizing risks associated with the situation.

In contrast, establishing timelines for response is less critical at the initial size-up stage, as understanding and addressing hazards should take precedence over scheduling. Preparing media statements is a task relevant to communication and public relations rather than immediate scene management. Although choosing exit routes for evacuees is important, it follows the assessment of hazards to ensure that any routes provided are safe and effective. Hence, the identification and mitigation of hazards are foundational to ensuring everyone’s safety and the effectiveness of the emergency response.
