Which of the following is a reason to conduct overhaul after firefighting operations?

Conducting overhaul after firefighting operations is essential primarily to identify the cause of the fire. This process involves a thorough investigation of the scene once the active flames have been extinguished. By examining the area, firefighters can gather evidence and analyze fire patterns, which can lead to a better understanding of how the fire started and its progression. Identifying the cause is crucial for preventing future incidents, applying lessons learned, and providing information that can be useful for fire investigations.

While the other choices touch on important aspects of fire scene management, such as structural integrity, flammable materials, and insurance assessments, they are not the primary objective of the overhaul process. The main focus during this phase is to ensure that all potential sources of ignition and causes of the fire are identified and documented. This information is invaluable for both the fire service and the affected parties.
