When the visible fire is out, our work at the scene is not necessarily finished. Every fire receives some level of investigation. Firefighters begin collecting useful information as they arrive: what they see, where smoke or flames are showing, what occupants or witnesses report, and how conditions change as the fire is brought under control. After extinguishment, those observations become part of determining where the fire began and what caused it.
Some fires require only a relatively brief examination because the circumstances are straightforward. The Fire Chief decides whether a more extensive investigation is necessary, including whether the scene should be photographed and a detailed report prepared. A closer investigation does not necessarily mean that arson is suspected. Accidental fires also have origins and causes that should be identified when the available evidence permits it.
Fire suppression and fire investigation are therefore not entirely separate tasks. The firefighters who first enter the building may also be the first people in a position to recognize and preserve information needed to explain what happened.
