What does size-up from the outside entail?

• A. Assessment from the exterior; look for smoke/stains, visible fire, structural integrity signs, and occupancy risk
• B. Full interior removal of occupants
• C. Only check the exterior for smoke
• D. Check interior only after entry

Answer: (A)

Size-up from the outside is the rapid, initial assessment performed without entering the structure. It uses exterior observations to gauge where the fire may be, how severe it is, and what hazards exist. Looking for smoke or stains on the exterior helps identify active or hidden fire, while visible flames can indicate location and intensity. Signs of structural distress, such as sagging beams, cracked or bulging walls, or a compromised roof, alert you to potential collapse and guide whether to attack defensively or prepare for interior operations. Evaluating occupancy risk from outside means considering the building type and who might be inside, which affects priorities and safety planning. All of these factors combine to shape the approach, resource needs, and safety measures before anyone goes inside.

Other options describe actions that require entry or are too narrow. Removing occupants interiorly isn’t part of exterior size-up, and focusing only on exterior smoke misses other crucial clues about fire spread and structural danger. Checking interior conditions only after entry contradicts the purpose of an outside, early assessment guiding safe, informed decisions.
