In fire operations, what is the term 'overhaul' used to describe?

The term 'overhaul' refers to the process of searching for hidden fires and extinguishing hot spots after the main fire has been suppressed. During overhaul, firefighters ensure that all potential sources of rekindling are identified and addressed. This is a critical phase of fire operations because even after visible flames are extinguished, residual heat or smoldering materials can continue to pose a risk. Firefighters carefully examine the entire area, often pulling apart structural elements and materials to ensure that no embers remain that could reignite the fire. This thoroughness helps to prevent future flare-ups, ensuring the safety of both the site and the surrounding structures.

The other options focus on different aspects of fire response or safety that are not related to the specific actions involved in overhaul. For example, extinguishing visible flames is part of the initial firefighting efforts, while inspecting equipment for safety pertains more to equipment readiness and maintenance rather than the aftermath of fire suppression. Saving animals from a fire scene is a noble effort but falls outside the scope of what overhaul specifically entails in firefighting operations.
