Which type of fire attack is made by directing the stream towards the ceiling through a window?

In firefighting, an indirect attack is designed to combat a fire by directing water or other extinguishing agents into the upper portions of a room, particularly towards the ceiling or upper walls. This method is particularly effective for cooling the combustion gases, which helps to reduce heat and lower the risk of flashover.

By targeting the ceiling through a window, firefighters can create a fog effect, allowing the steam generated to displace oxygen and control the fire without directly attacking the flames. This strategy is especially useful in situations where you may be confronted with dangerous conditions inside the structure.

This approach is common in scenarios where the interior conditions are too hazardous to enter, such as when smoke, heat, or flames prevent safe access. Understanding when to use an indirect attack is crucial, as it leverages thermal dynamics to control or suppress a fire effectively from a safer distance.
