During overhaul and searching for hidden fires, which of the following is NOT true?

The choice regarding cutting wires to create appropriately sized holes for tasks is not true because this procedure can pose significant safety hazards. Cutting wires during overhaul can inadvertently sever live electrical lines, leading to risks such as electrocution or electrical fires. Instead, firefighters should utilize existing access points or other safe methods to gain access without compromising safety.

In contrast, using water to extinguish embers is a standard practice to ensure all smoldering materials are fully extinguished. Checking for hot spots is crucial to prevent re-ignition, as these areas can retain enough heat to reignite a fire. Furthermore, thermal imaging cameras are valuable tools for detecting hidden heat sources that the naked eye cannot see, enabling firefighters to locate and extinguish any remaining pockets of fire effectively. Each of these actions reinforces a thorough and safe approach to overhaul and fire suppression.
