What does an interior attack entail in ARFF?

• A. A passive cooling method without entering the aircraft.
• B. A controlled fire attack from within the aircraft, usually after cooling and hazard assessment.
• C. Venting flames from the tail section only.
• D. A rapid exterior flood from outside the hull.

Answer: (B)

Interior attack means applying the fire suppression from inside the aircraft after you’ve cooled the structure and completed a hazard assessment. This approach is used when the fire is reachable from within and it’s safe to enter, allowing you to directly reach the source of the flames or the most critical compartments (like the cabin, cargo hold, or avionics bay) with an extinguishing agent. Cooling the exterior helps protect you from heat and structural failure, reducing the risk of flashover as you move toward the fire. Once inside, you can knock the fire down more quickly and prevent re-ignition by addressing the fuel and ignition sources at their origin, all while coordinating with any exterior teams and maintaining safe egress and scene control.
