What should always be in place during the overhaul phase of firefighting?

During the overhaul phase of firefighting, having a charged hose line is essential for safety and effective fire control. Overhaul involves checking for hidden fires and potential flare-ups after the main fire has been extinguished. Even after the visible flames are out, there may still be embers or hot spots that could reignite. A charged hose line ensures that firefighters can quickly respond to any signs of re-ignition or flare-ups, providing an immediate means to control any residual heat or flames that could pose a danger to both personnel and property.

Furthermore, a charged hose provides a measure of protection for firefighters as they move deeper into the structure to assess and mitigate fire damage. This precaution is critical, especially in environments where structural integrity may have been compromised by the fire. Having a hose line ready allows for not only active firefighting but also for maintaining a safe operation during a potentially hazardous overhaul process.
