Shut off the fuel supply. In applicable situations, the first thing you should do for fires involving flammable liquids is to turn the fuel supply off.[20] For instance, if a static discharge ignites gasoline around a fuel pump, the first thing you should do is hit the emergency shutoff valve located nearby at all pumping stations. This act severs the small fire from the very large fuel sources around it.
o In many instances where the flammable liquid is the only fuel source, the fire may extinguish itself as soon as you cut the fuel supply.
