Never place the grill close to a combustible material. The outside of the grill can radiate a lot of heat and accidental ignition could result if placed too close to wood, paper or other flammable material.
Make sure that your grill is of sturdy construction and doesn’t wobble or lean to one side.
When you’re done grilling, place the lid on the charcoal grill and close all vents. Turn a gas grill off at the burners and the source.
Know where your fire extinguisher is and have it handy it case of a mishap. Closing the lid will reduce the oxygen and eliminate the flare-up.
