The short answer

Stay Alert While Cooking

Grease fires often start when oil overheats, which can happen in seconds. Never leave the kitchen while frying, boiling, or sauteing. If you must step away, turn off the burner first. Keep your focus on the pan, not your phone or the TV.

Use a timer as a reminder, even for short tasks. If you feel tired or distracted, lower the heat or stop cooking. A moment of inattention can turn a small spill into a dangerous flame. Your presence is the first line of defense.

Manage Oil Temperature

Oil smokes before it catches fire, so watch for wisps of smoke. Use a kitchen thermometer to keep oil below its smoke point, typically around 375 to 400 degrees Fahrenheit for most cooking oils. Heat oil slowly and adjust the burner as needed.

If you see smoke, remove the pan from the heat and turn off the burner. Let it cool completely before moving it. Adding food to hot oil can cause splatters, so pat items dry first. Lower the heat after adding food to maintain a steady temperature.

  • Keep a lid within reach before you start cooking
  • Use a thermometer to monitor oil temperature
  • Dry food items before placing them in oil
  • Turn handles toward the back of the stove
  • Clean grease buildup from the stove regularly

Know How to Smother a Fire

If a grease fire starts, do not use water. Water spreads the flames and can cause serious burns. Instead, turn off the burner and cover the pan with a metal lid or a baking sheet. Leave the lid on until the pan is completely cool.

Baking soda can also smother small fires, but never use flour or baking powder. Those powders can explode in the heat. A Class B fire extinguisher works well, but only if you know how to use it safely. Keep one in your kitchen and check its pressure regularly.

If the fire grows beyond the pan, leave the house immediately and call 911 from outside. Do not try to carry the pan, as the oil can splash and burn you. Your safety and your family's safety come first.

Clean Your Kitchen Regularly

Grease buildup on stovetops, range hoods, and vents can ignite easily. Wipe down surfaces after each cooking session, especially around the burners. Clean the range hood filter monthly to remove oil residue that can catch fire.

Check for old grease in the oven and under the stove. Use a degreaser or a mixture of baking soda and water to scrub stubborn spots. A clean kitchen reduces the chance of flare-ups and makes it easier to spot potential hazards.

Keep your kitchen well-ventilated to reduce moisture that can mix with grease. Open windows or use an exhaust fan while cooking. Good airflow helps keep surfaces dry and less prone to buildup.

  • Wipe stovetop after every use
  • Clean range hood filter monthly
  • Scrub oven interior regularly
  • Check for grease on walls and cabinets
  • Store flammable items away from the stove

Handle a Grease Fire Safely

When a grease fire occurs, your first move is to turn off the burner. Then slide a metal lid over the pan to cut off oxygen. Keep the lid in place until the pan cools completely. Never lift the lid early.

If you have a fire extinguisher, aim at the base of the flames and sweep side to side. If the fire spreads to cabinets or curtains, get everyone out and call emergency services. Do not re-enter until firefighters say it is safe.

After a fire, assess the damage. If smoke or soot has affected your walls, floors, or belongings, you may need professional help. Water damage from extinguishing efforts can also occur, so consider contacting local water damage pros if needed.
