Cooking-Related Fires
The Spruce / Meg MacDonald
Cooking fires are among the most common types of house fires, causing around 49 percent of all residential fires. They are very often caused by greases that become overheated on a stove or in an oven. Grease is highly flammable when it gets hot enough (about 600 degrees Fahrenheit, on average) and when it reaches that point, it can combust spontaneously, even without direct flame contact. Once grease is ignited, it is very difficult to smother the flames.
Never leave the kitchen unattended when cooking in oil or when cooking a food that produces grease, such as bacon. Most kitchen fires start because when a homeowner leaves food cooking unsupervised on a stove or in an oven. By the time the fire is discovered, it’s usually too late. Thoroughly clean your cookware to prevent grease from building up over time.
Portable cooking appliances, such as toasters and electric griddles can also be a source of fires. Never leave these portable appliances unsupervised, and make sure they are cool to the touch before storing them away. Toasters should be regularly cleaned of crumbs that might ignite if they build up inside the appliance.
During the outdoor cooking season, barbecue grills left unattended on a wooden deck or near the exterior walls of a home can also be a source of fire. 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.
