What is considered the biggest hazard during the overhaul process?

During the overhaul process, the most significant hazard is the compromization of structural integrity, which can lead to collapse. This phase occurs after the bulk of the fire has been extinguished and firefighters are searching for hidden fire extension and ensuring that all fire has been fully extinguished.

During overhaul, firefighters often work in buildings that may have sustained fire damage, which can weaken structural components such as walls, floors, and ceilings. The heat and flames from a fire can severely degrade a structure's ability to support its own weight, resulting in an increased risk of collapse.

Firefighters may find themselves in precarious positions as they remove debris or check for smoldering hotspots, making it essential to be aware of the condition of the structure at all times to avoid injury or fatalities from collapse. Recognizing this risk emphasizes the importance of ensuring safety measures, such as having a structural assessment done and maintaining situational awareness while performing overhaul operations.

While inadequate water supply, excessive smoke inhalation, and electrical hazards present risks, the potential for structural failure represents an immediate and critical threat that can have devastating consequences during this phase of firefighting operations.
