Why is it important to remove and inspect layers of debris from a fire?

The primary importance of removing and inspecting layers of debris from a fire lies in the process of accurately determining how the fire developed, including the sequence of events during the burn. This information is crucial for understanding the fire's behavior, including the materials involved and potential accelerants that might have been used. Analyzing the layers of debris can reveal critical insights into how the fire spread, allowing firefighters and investigators to identify factors that contributed to its intensity and duration. This understanding can guide future fire prevention strategies and improve fire suppression tactics by providing valuable information about fire dynamics.

Other considerations such as assessing structural damage, recovering lost equipment, and ensuring safety for firefighters are certainly important tasks following a fire incident. However, establishing the sequence of how long the fire burned is directly tied to the specifics of the forensic investigation process, which is vital for learning from past incidents and preventing future occurrences.
