What should be done regarding overhaul in a fire investigation?

In fire investigation, the process of overhaul refers to the systematic examination of the fire scene to identify hidden hotspots, ensure that the fire is fully extinguished, and gather evidence related to the cause and origin of the fire. Delaying overhaul until the cause is determined is crucial as it allows investigators to preserve the integrity of the scene and avoid disturbing potential evidence.

Conducting overhaul too early can lead to the loss of critical information that may contribute to understanding how the fire started and spread. Investigators rely on physical evidence that can be inadvertently destroyed if crews begin removing debris or moving items without careful assessment. By postponing overhaul until they have gathered all necessary evidence regarding the fire's cause, investigators can better support their findings and preserve the context of the scene for analysis.

This approach also aligns with protocols in fire investigation, ensuring that all actions taken do not compromise the investigative process.
