OCFA Strategy and Tactics – Truck Operations Practice Test

In garden-style offensive operations, creating an escape path for heat and smoke is essential to make interior attacks safer and more effective. Venting over the unit involved directly opens up the space above the fire, usually via the roof or upper openings, allowing hot gases to exit upward. This vertical ventilation reduces heat buildup, improves visibility, and helps crews advance with a line and search more safely. The other actions—stripping on both sides of the involved unit, using fire walls to partition and slow spread, or merely coordinating with the engine company—are valuable tactics in their own right, but they do not describe the specific vertical ventilation action that this tactic emphasizes.
