Which tool is commonly used during overhaul to pull down ceilings?

The pike pole is commonly used during overhaul to pull down ceilings because of its long, slender design and pointed tip which allows firefighters to reach and manipulate materials that may be located high above, such as ceiling tiles or drywall. During overhaul, it's essential to ensure that any hidden fire or embers behind the ceilings or walls are discovered and extinguished. The pike pole provides the necessary leverage and control to remove these materials safely and effectively, making it a valuable tool in the firefighting process.

While other tools like the Kelly tool, Halligan tool, and carryall have their specific applications, they are not primarily designed for the ceiling-pulling task during overhaul operations, thus making the pike pole the preferred choice in this scenario.
