Which activity should NOT occur during the scene size-up?

During the scene size-up, the primary focus is on assessing the overall safety of the scene, identifying potential hazards, and gathering essential information to facilitate effective incident management. While airway management is a critical component of patient care, it is not part of the scene size-up process. This phase is intended for situational awareness and evaluation—not for delivering medical interventions.

The other activities mentioned, such as determining the mechanism of injury, assessing the extent of a patient's entrapment, and identifying the need for additional resources, are all vital components of scene size-up. Understanding the mechanism of injury helps responders anticipate potential injuries, while assessing patient entrapment informs the required extrication techniques. Additionally, determining the need for extra resources ensures that appropriate support is available for both patient care and scene management as the situation evolves. These activities collectively lay the groundwork for an effective response before any actual treatment or intervention is initiated.
