Which of the following is NOT one of the phases of a size up?

The correct answer highlights that post-incident reports are not considered one of the phases of a size up. A size up involves evaluating the situation at the scene of an incident to make informed decisions about how to manage the response effectively.

The phases of a size up include pre-incident information, which helps responders prepare before they arrive on-scene, the initial size up, which is the assessment conducted upon arrival to gauge the current status of the incident, and ongoing size up, which refers to continual assessments that occur as conditions change throughout the incident.

Post-incident reports, while essential for evaluating response effectiveness, identifying lessons learned, and improving future operations, occur after the incident has concluded. They do not contribute to the real-time decision-making process that a size up entails. Therefore, this distinction is crucial for understanding what constitutes the size up phases versus the evaluative processes following an incident.
