What type of stream is effective in pushing burning flammable liquids?

Using the leading edge of a fog stream is particularly effective in pushing burning flammable liquids due to its unique properties. A fog stream consists of tiny droplets of water that create a curtain of mist, which can effectively knock down heat and push flames away from the fire while also displacing the flammable vapors that may be present. This method is essential in situations involving flammable liquids, as it allows for better control over the environment, minimizing the risk of re-ignition and enhancing the safety of firefighters at the scene.

The use of a fog stream provides both cooling and a means of directing the water toward the burning material without adding to the available fuel or causing splashing, which may exacerbate the fire. By creating a barrier of water droplets, it interrupts the combustion process effectively, making it suitable for flammable liquid fires.
