If arson is a possibility or if anyone if seriously injured, the incident becomes a crime scene and the chief must secure the area and preserve as much evidence as possible. The chief must determine whether there are any code violations evident at the scene. If so, then code enforcement personnel are called to the scene to determine what action to take. The chief must also consider temperature and the wind direction. If the temperature is very hot or very cold, it may be necessary call in additional personnel to relieve the firefighters.
Strong winds can spread the fire to nearby structures.
The chief must also attend to safety concerns at the scene. We have one slightly injured civilian. At this point, the chief would acknowledge the message from the Search sector and notify the Medical sector to prepare to treat an injured person. Ventilation, take fans to the front of the building. This means that the ladder crew has placed a hole in the roof above the fire, creating a makeshift chimney, which allows the toxic gases and super-heated air to escape from the burning building.
