Which of the following would not be considered a part of the initial assessment during scene size up?

The initial assessment during scene size-up is primarily focused on evaluating the scene to ensure safety and gather crucial information about the environment and potential threats. This process includes identifying potential hazards, determining the number of patients involved, and assessing the overall safety of the scene.

Identifying airway threats is typically part of the primary assessment that follows the initial scene evaluation, as it is crucial to establish effective airway management once the scene is deemed safe. However, assessing the patient's level of consciousness, which falls under the primary assessment, is not part of the initial scene size-up. This assessment happens after the initial dangers have been identified and the scene is secure, allowing for a focused evaluation of individual patients.

Thus, the option refers to a critical assessment aspect but takes place after the initial scene size-up is completed, supporting its identification as not being part of the scene size-up process.
