In the residential search size-up, which phase includes factors such as occupancy type and time of day?

The phase that includes factors such as occupancy type and time of day is the pre-arrival/pre-planning phase. This phase is crucial for establishing a clear understanding of the environment before responding to an incident. By considering the occupancy type, the responding team can determine potential hazards, the likelihood of occupants being in danger, and the best strategies for search and rescue operations. Similarly, the time of day can influence visibility conditions, expected occupancy levels, and potential complications that may arise during the operation, such as children being home during the day vs. adults being present at night.

This pre-planning phase sets the foundation for effective decision-making upon arrival, as the responders can tailor their approach based on the context provided by these factors. The other phases—post-arrival size-up, exterior size-up, and interior size-up—focus on observations made after the team arrives at the scene and do not involve the same level of preparatory analysis related to the initial environmental factors.
