What is the primary goal when applying defensive strategy during a major structure fire?

• A. Enter to conduct search immediately.
• B. Protect exposures and limit flame spread.
• C. Ventilate only for smoke removal.
• D. Withdraw when command says so.

Answer: (B)

When applying a defensive strategy at a major structure fire, the main goal is to keep the fire from growing by protecting exposures and limiting flame spread. This means focusing on exterior actions to prevent the fire from reaching nearby buildings, vehicles, or other exposures, and using tactics that slow or stop the fire’s advancement. Shifting to this approach helps reduce risk to firefighters and occupants while preserving as much of the surrounding property as possible.

Entering to conduct a search immediately is more aligned with an interior, offensive approach and isn’t the priority when the plan is to defend exposed areas. Ventilation can help with smoke management, but it isn’t the primary objective of defensive strategy. Withdrawing is a necessary action under certain conditions, but it’s not the purpose of the defensive strategy itself; it’s a decision based on safety and command directions.
