What is a transitional attack and when should it be used?

• A. An exterior or doorway attack to begin cooling and controlling the fire before interior entry, used when there are potential life hazards or limited visibility
• B. An interior attack from the doorway to immediately enter and attack the fire
• C. A defensive attack using aerial devices only
• D. A ventilation-only operation

Answer: (A)

A transitional attack means applying water from the exterior or at the doorway to begin cooling and controlling the fire before interior entry. This approach lowers heat and slows the fire’s growth from the outside, which improves conditions inside and makes it safer for crews to advance, search, and apply a full interior attack.

Use it when there may be life hazards or when visibility is poor or limited. In those conditions, rushing interior entry can be dangerous or inefficient, so cooling the fire first from the outside or at the threshold helps reduce heat, smoke, and flames, creating a safer, more effective path for interior operations.
