What information is critical to record during a fire investigation?

Recording details from witnesses and occupants is critical during a fire investigation for several reasons. Witnesses can provide firsthand accounts of what they observed before, during, and after the fire, which can be vital for establishing a timeline of events. They may also offer insights into how the fire started or advanced, details about smells or sounds, and any unusual activity around the building prior to the incident.

Occupants can provide information about the building, such as escape routes, room uses, and any potential fire hazards. Additionally, their experiences can help to assess fire dynamics and victim behavior, which can be essential for understanding how the fire developed and spread. This direct testimony can guide investigators in determining the cause of the fire and identifying safety issues to prevent future occurrences.

While weather conditions, the names of firefighters present, and time of arrival are also important factors in a fire investigation, the direct accounts from witnesses and occupants often hold more weight in constructing a clear picture of what unfolded during the incident.
