Question 7 • Principles of Fire and Rescue
Correct Answer:
An incident commander can implement an action plan using an offensive, defensive, or transitional approach. An offensive strategy sends firefighters inside to attack the fire and search for occupants. It is preferred when the structure is stable, an interior attack is possible, and lives may be saved. Its main risks are exposing firefighters to collapse, heat, smoke, or rapidly changing fire conditions. A defensive strategy keeps firefighters outside and directs water onto the fire from safer positions. It is preferred when a building is unstable, the fire is too advanced, or an interior attack cannot be made safely. The tradeoff is that occupants may be harder to rescue and the fire may spread or destroy more property before it is controlled. A transitional strategy begins with an exterior stream to reduce the fire’s intensity, then transitions to an interior attack if conditions permit. It can be useful when an immediate exterior knockdown may make entry safer. However, the transition must be coordinated: delaying entry can cost valuable rescue time, while moving inside too soon can still put crews in danger. The commander must continually reassess conditions and change the approach when needed.
