During overhaul operations, having a charged hose line always ready for use is crucial for several reasons. Overhaul involves checking for hidden fires, which can still pose a significant risk even after the main fire has been extinguished. A charged hose line enables firefighters to quickly address flare-ups or rekindle a fire that may have gone undetected in hidden areas, such as walls or ceilings.

Ensuring that a hose line is ready allows for immediate action to be taken if any signs of fire resurgence are observed. This readiness can make a substantial difference in containing the fire and protecting both the firefighters and the structure.

In contrast, the idea that a charged hose line should never be used or is optional can jeopardize safety, as it may lead to delays in responding to resurgence of fire. Likewise, delegating the use of a charged hose line to the discretion of a safety officer could cause confusion and delay evacuation or evacuation protocols, depending on individual judgments and current conditions. Having a standard practice, such as always keeping a charged line ready, supports a safer and more effective approach to overhaul operations.
