Before interior attack, what is the purpose of performing a 360-degree survey of a structure?

• A. To determine the exact extinguishing agent to use.
• B. To locate water supply lines only.
• C. To identify hazards, potential collapse zones, hidden compartments, and optimal entry/egress routes.
• D. To rehearse rescue scenarios for training.

Answer: (C)

The main idea behind a 360-degree survey before interior attack is to establish full scene awareness and plan tactics that keep crews safe. By looking all around the building, you quickly gather critical information that affects every move you make inside. This survey helps you identify hazards you might encounter on entry—things like signs of structural weakness, obvious collapse indicators (bulging walls, cracked or sagging beams, unstable roofs), and areas where the fire may be driving or hidden compartments behind walls or in voids. It also maps out optimal entry and egress routes: where it’s safest to approach, which doors or windows offer the best access points, and the paths that give you quick, reliable exits if conditions worsen. Knowing these factors upfront allows you to plan a more effective and safer interior attack, coordinate ventilation and search strategies, and position crews and lines where they’re most likely to succeed. This isn’t about choosing extinguishing agents, locating water supply alone, or rehearsing rescues. Those elements come after you’ve secured a solid outside understanding of hazards, structure stability, and the best routes for entry and exit.
