First arriving firefighters should note which of the following?

• A. Vehicles and people present in the area, status of doors and windows, condition of contents of the rooms, whether in usual order, ransacked, or unusually bare
• B. The color of the smoke
• C. The type of animals inside the building
• D. The brand of the radio in use

Answer: (A)

The key idea is that the first arriving firefighters perform a rapid scene size-up to establish life safety priorities and guide immediate actions. In that quick assessment, noting what’s in and around the building helps you understand potential occupants, entry and exit points, and how the fire and doors or windows might affect access and egress. Checking doors and windows tells you where you can safely enter or where openings could let heat and smoke spread, while observing the condition of contents and whether rooms are in their usual order or appear ransacked or unusually bare gives clues about occupancy status, potential search needs, and whether there may have been forced entry or recent activity. All of this information shapes your initial strategy, resource needs, and safety precautions from the outset.

Color of the smoke, the presence of animals inside, or the brand of the radio don’t provide the same immediate, actionable guidance for the initial size-up and are not priorities at this stage.
