What strategy should buildings under construction, renovation, or demolition default to?

• A. Offensive
• B. Defensive
• C. Contained
• D. Evacuation

Answer: (B)

When a building is under construction, renovation, or demolition, the environment is full of unknowns and instability—hidden voids, weak floors or walls, debris, and exposed utilities. The safest default is a defensive posture: keep operations outside the structure or behind barriers, protect surrounding exposures, and control the scene from a safe distance. This approach prioritizes life safety and minimizes the risk to responders by avoiding interior attacks in a hazardous, unpredictable environment. It also helps prevent the fire or hazard from spreading to nearby buildings while crews establish safer conditions, secure utilities, and plan for possible deeper actions only when the scene is stabilized. Other strategies assume safer interior conditions or occupants, which don’t fit the realities of construction sites, so they aren’t the default choice.
