Non-scene data refers to information collected from sources that are not directly related to the physical fire scene itself. This type of data can include reports, witness statements, historical data, and other relevant documentation that can help investigators piece together what happened before, during, and after the fire incident.

Utilizing non-scene data is crucial for establishing timelines, understanding fire behavior, and identifying potential causes or contributing factors to the incident. It complements the evidence gathered at the scene by providing context and additional insights that may not be visible or available during the on-site investigation. This broader perspective is essential in fire investigation and aligns with the comprehensive approach outlined in NFPA 921, which emphasizes the importance of analyzing all available information to form sound conclusions.
