Evaluating the Scene
Assess Scene Security at the Time of the Fire
Source: National Institute of Justice, Fire and Arson Scene Evidence: A Guide for Public Safety Personnel
Contact security and suppression system monitoring agencies to
obtain information and available documentation about the design
and functioning of the systems.
Observe and document the position of timers, switches, valves, and control units for utilities, detection systems, and suppression systems, as well as any alterations to those positions by first responders.
Observe and document the condition of doors, windows, other openings, and fire separations (e.g., fire doors). Attempt to determine whether they were open, closed, or compromised at the time of the fire.
Ask first responders where entry was made, what steps were taken to gain entry, and whether any systems had been activated when they arrived at the scene.
