ABSTRACT:
A method and system for extinguishing fires in large buildings containing a plurality of fire fighting sections wherein a fire occurring in any of the fire fighting sections is detected to signal a central control panel which produces a warning in that section indicating to occupants that they should quickly leave, the fire fighting section in which the fire occurred being shut tight by fire doors or the like a predetermined time after the warning is provided and after the occupants have escaped. Once the fire fighting section in which the fire has broken out is isolated or shut tight, the flame, smoke and air are evacuated from the fire fighting section via a suction system positioned adjacent the floor of the fire fighting section while a fire extinguishing agent is injected into the fire fighting section from a position adjacent the ceiling such that the fire extinguishing agent is evenly distributed throughout the fire fighting section over articles therein due to the draw created by the evacuation from a position adjacent the floor.
