What does a combination attack involve?

• A. Ceiling-level attack only
• B. Floor-level attack only
• C. A combination of ceiling-level and floor-level water application
• D. Indirect attack from above

Answer: (C)

A combination attack means using water from two levels at once—cooling the hot gas layer from above while directly attacking the fire at the base from below. Cooling the ceiling gases helps prevent flashover and reduces heat transfer to the room, while the floor-level flow directly suppresses the fuel and knockdowns the fire more efficiently. This coordinated approach is especially useful when there’s a significant heat buildup but the fuel source is reachable, allowing faster control of the fire and safer progression for the team. The other approaches—ceiling-only or floor-only—don’t address both cooling the overhead heat and directly attacking the fuel, and indirect from above is a different tactic that doesn’t describe this combined method.
