When info from the scan indicates that the temperature is down in the fire compartment, it might be time to start ventilating. The objective of ventilating is to get rid of smoke/steam to increase visibility. In order to ventilate, you need at least two openings, one inlet and one exhaust or outlet. When choosing ventilation direction, consider wind direction. It is hard to ventilate against the wind. Practice with PPV in order to understand how wind and building layouts affect ventilation. Most risks may be mitigated by appropriate measures.
The Cobra SAVE method of Scan, Attack, Ventilate and Enter is developed by firefighters. It is a dynamically applied method where each step could be used in any order.
