Water also helps to suppress the production of flammable gases and vapors that can contribute to the fire's spread. Firefighters typically utilize hose lines to deliver water directly to the base of the fire, targeting the hot spots and areas of active combustion. This method has been shown to be effective in not only extinguishing flames but also in preventing the fire from re-igniting.

Evacuating the building is crucial for ensuring the safety of occupants, while fire blankets are more suited for smaller fires. Creating fire breaks is a technique often employed during wildfires rather than in structure fires. Thus, the use of water remains the fundamental and most efficient technique for directly controlling
