What is a transitional attack?

• A. An offensive operation initiated by a brief exterior, indirect attack into the fire compartment to initiate cooling
• B. A defensive operation conducted from outside
• C. A full interior attack with multiple lines
• D. An exterior water application only

Answer: (A)

Transitional attack means starting with a brief exterior water application aimed into the fire compartment to begin cooling before interior entry. The goal is to rapidly reduce heat and loosen the hot gas layer, which makes entering the space safer and more controllable for firefighters doing the interior work. By cooling the environment from outside, you slow the fire’s growth, improve visibility, and reduce the risk of extreme heat and flashover for crews, while still moving toward an interior attack once conditions allow. This approach contrasts with purely defensive work from outside, a full interior attack with multiple lines right away, or using exterior water only without transitioning to interior operations.
