A heated grill next to a wooden fence can easily cause fire, and grills have been known to ignite the exterior walls of a home or garage if positioned too close. Small grease fires can be extinguished quickly by turning off the heat and smothering the fire with a metal lid. Sprinkling baking soda or salt on the fire will also put it out, as well. A class-B or class-K fire extinguisher is also recommended, although the chemicals can create a notable cleanup issue. With serious fires, make no attempt to put out the fire. Instead, call the fire department immediately. Under no circumstances should you dump water over the grease fire, as this can cause the hot grease to explode and throw burning grease over the area.
