• Water can be used on wood, paper, or cloth, but don't use water on an electrical fire (can cause shock) or a gasoline fire (it will spread the flames).

• Position yourself upwind. Let the wind carry the extinguisher to the fire. 

• Continue until whatever was burning has been cooled. Absence of smoke or flame does not mean the fire cannot restart.
