Using a charged hose line is essential for extinguishing hidden fires during the overhaul phase of firefighting operations. A charged hose line refers to one that is actively filled with water and ready for use. During overhaul, firefighters often encounter smoldering materials or hidden pockets of fire that may not be immediately visible. The charged hose line allows firefighters to quickly and effectively apply water to these areas, ensuring that any remaining heat or smoldering materials are fully extinguished, preventing rekindling of the fire.

In contrast, a non-charged hose line lacks water pressure and would not be effective for putting out active or smoldering fires. A dry hose line, which also does not contain water, is similarly inadequate for firefighting. The term "bursting" does not accurately describe any standard hose type needed for fighting fires, as a bursting hose indicates a malfunction that could compromise the firefighting effort. Thus, the charged hose line is the most appropriate and effective tool for combating hidden fires during the overhaul stage.
