Which action best describes a thorough circle around the incident area to observe conditions?

• A. Starting with interior search
• B. Shutting down power
• C. Doing a 360
• D. Installing water supply

Answer: (C)

The main idea here is scene size-up through a full exterior survey. Performing a 360-degree walk around the outside of the incident gives you a complete picture of conditions before you go inside. You can see where the fire is located, how smoke and heat are moving, and which parts of the building or nearby exposures are at risk. You also identify hazards like structural integrity, potential collapse zones, hidden openings, and easy or blocked access points. This broad view helps you decide whether interior entry is safe, where to position units, and how resources should be allocated (for example, whether you’ll need to shut power or set up a water supply). Without this outer-circle observation, decisions would be based on partial information and could put crews at greater risk. Interior search should come after you’ve completed this exterior assessment and confirmed it’s safe; shutting down power and installing a water supply are important actions that stem from the size-up but are not the step that provides the critical full-scene view.
