Which forcible entry tool extends a firefighter's reach for sweeping across floors?

The flat-head axe is designed with a flat, wide blade that allows firefighters to use it effectively for sweeping debris or obstacles across a floor. Its shape and weight make it particularly useful for reaching and clearing areas that are hard to access without stepping into unsafe zones, which is often necessary during firefighting operations. The extended reach provided by the flat-head axe enables firefighters to push or pull objects, allowing for safer navigation in debris-filled environments.

While other tools like the Halligan tool, chainsaw, and pickhead axe serve their own unique purposes, they are not specifically designed for sweeping across floors. The Halligan tool is primarily used for prying and is effective in forcible entry but lacks the sweeping capabilities. The chainsaw is used for cutting through materials but does not have a sweeping function. The pickhead axe has a head shape that is suited for splitting and penetrating, rather than sweeping. Thus, the flat-head axe stands out as the most suitable tool for this specific function.
