What does "size-up" include on initial arrival to a working incident?

• A. The latest sports scores.
• B. Building type, occupancy, fire location, potential hazards, access/egress, resources needed.
• C. The color of the doors.
• D. The number of windows only.

Answer: (B)

Size-up on initial arrival is the rapid assessment firefighters perform to shape the first actions and keep everyone safe. It focuses on six key elements: building type and construction, who might be inside (occupancy), where the fire is located and how it might spread, potential hazards present (like structural instability, hidden fires, utilities, or hazardous materials), access and egress for both firefighters and occupants (entry points, stairwells, hydrants, escape routes), and the resources needed (numbers of personnel, additional lines, ventilation tools, and equipment). This information helps determine whether to attack or defend, where to place lines, how to ventilate, and what extra resources to call for. Details like sports scores, door color, or simply the number of windows don’t impact tactical decisions and aren’t useful for guiding initial actions.
