First, don’t panic. Keep a box of baking soda in a handy spot for dousing flare-ups in a toaster or stovetop pan. Avoid tossing water on the blaze, and don’t try to smother the flames with a dishtowel or anything that could catch fire. The better course of action is to use a pot lid to extinguish the flames. If it’s an oven fire, don’t open the door—close the oven and the fire should extinguish itself. Although some fire extinguishers are rated to extinguish grease fires, those handheld fire fighters can spread flames rather than extinguish them when used improperly. Educate yourself on the types of extinguishers and how to use them so you're always ready in case of a disaster.
