Which step is part of ventilating a conventional flat roof?

• A. Sound safe working area
• B. Inspection Cut
• C. Indicator Hole every 10'
• D. Begin dicing operation for heat hole and expand as necessary

Answer: (B)

In ventilating a conventional flat roof, the essential step is to perform an inspection cut. This small exploratory cut lets you look behind the roof surface to verify what’s inside—whether fire is present, where it’s traveling, and if the roof structure is safe to continue cutting. By checking conditions firsthand, you can decide the best place to extend the ventilation opening and avoid pushing fire into voids or compromising the roof.

Other options describe safety checks or nonstandard actions, but they aren’t the specific step that directly guides the ventilation process. An inspection cut is the targeted, information-gathering action that informs the subsequent ventilation steps.
