How to Put Out a Grease Fire in the Kitchen Safely (2026)

Turn off the burner, slide a metal lid or flat baking sheet over the pan, and leave it there until the pan is completely cool. That is how to put out a grease fire in the kitchen, and it takes about ten seconds of work. Never throw water on burning oil, and never pick up the pan.

Cooking is the leading cause of home fires. National Fire Protection Association figures cited across fire safety research put reported home cooking fires near 158,400 a year, roughly 44 percent of all home fires, with most traced to unattended cooking. A shallow flame in a skillet can become a wall of flame in under a minute, so the plan below matters more than the meal.

If flames are spreading, the ceiling is involved, or smoke is filling the room: stop what you are doing, get everyone out, and call 911 from outside. Do not try to be a hero over a skillet.

A grease fire is a Class K fire: cooking oil, butter, or rendered fat heated past its smoke point until the vapor ignites and burns in open air. Fire needs three things, the fire triangle: heat, fuel, and oxygen. Turn off the burner to remove heat. Covering the pan removes oxygen. The fuel stays, but with no heat and no oxygen the flames die on their own.

That is why the order matters. Most mistakes happen in the first fifteen seconds, when instinct says reach for water.

What You Need to Put Out a Grease Fire Safely

The best equipment is the stuff already sitting on your stove. Everything below is cheap, and the first two items are the ones that actually stop most fires.

• A metal lid sized to the pan. This is the primary tool, not the backup. A rimmed baking sheet or a flat cookie sheet works if the pan is wider than your largest lid.
• A flat metal baking sheet. Useful for a deep fryer, a wok, or any vessel too wide for a lid. Keep one within arm’s reach of the range.
• A box of baking soda. Optional, and contested. Fire departments disagree about it, which is worth understanding before you need it.
• A fire extinguisher rated for grease. Look for a black hexagon with the letter K on the label, or a multipurpose Class ABC unit rated for Class B flammable liquids.
• Heat-resistant gloves or oven mitts. For a pan that has been burning for more than a few seconds.
• A clear route out of the kitchen. Know where the door is and make sure nobody is blocking it before you start cooking.

Items that must never be within reach during a grease fire: a glass lid, a wet or dry kitchen towel, a bucket of water, and any bag of flour, sugar, or baking powder sitting near the stove. Flour and baking powder look exactly like baking soda in a panic, and the difference matters.

Keep a working smoke alarm inside the kitchen and outside the sleeping area, and replace the batteries twice a year. It buys you the thirty seconds of warning that decides whether you fight the fire or run.

Step-by-Step: How to Put Out a Grease Fire in the Kitchen

These five steps follow the order fire departments and fire marshals describe. Work fast, but do not skip ahead to a step that sounds more dramatic.

Step 1: Turn Off the Heat and Assess the Fire

Reach for the burner control without putting your face over the pan, and without leaning through smoke or flame. On a gas range that means the knob at the front; on a cooktop, the switch or the breaker. Then look at what you have before you act.

A small contained fire means flames are inside the pan, roughly a foot tall or less, with no smoke gathering at the ceiling and no fire on the hood, wall, or cabinets. That is a fire you can put out with a lid.

Leave immediately and call 911 if flames reach the hood or the upper cabinets, if smoke is thick enough to hide the ceiling, if the pan is a deep fryer or a large stockpot you cannot cover, or if you have no cover on hand. Nobody has ever been criticized for leaving a grease fire and calling for help.

Step 2: Cover the Pan with a Metal Lid

Slide the lid on from the side, close to the surface of the stove, so it lands flat and seals the rim. Do not drop it straight down from above, and do not put your face over the pan, because hot steam and vapor escape the moment the lid hits and can scald you. A baking sheet works the same way for a wide pan.

Leave the lid exactly where it is. Hot oil keeps enough heat to reignite, and lifting the cover to check lets oxygen straight back in. Most pans need 30 minutes or more to cool completely. When you can pick it up with a bare hand at the handle without feeling warmth, the fire is out.

Skip glass lids. Thermal shock shatters them and throws hot fragments across the stove. Skip the fire blanket as your only tool, too: in one account on r/thatLookedExpensive, a fiberglass fire blanket burned through in about two seconds over very hot oil. A blanket can help knock down flames reaching up toward a hood, but the lid is what smothers the pan.

Step 3: Use Baking Soda for a Small Fire

Baking soda is the one kitchen powder that chemically works on small grease fires. Heated, sodium bicarbonate releases carbon dioxide, and a heavy pour across the surface of a small pan can smother the flames. The catch is quantity. A couple of tablespoons, as one cook on r/interestingasfuck found the hard way, can produce a bigger flame than it puts out, because you have not covered the fuel at all.

Fire departments are split. Many still list baking soda, and the Google AI Overview for this question recommends it. The Oklahoma City Fire Department, as reported by KFOR, advises against salt, baking powder, sugar, flour, and any other kitchen powder, precisely because people grab the wrong white bag under stress. Our advice is to treat baking soda as a backup, never as your first move, and never as a substitute for a lid.

Flour is the powder to stay away from entirely. It is finely ground starch, and starch suspended in air near a flame ignites fast. A scoop of flour can make a small fire into a large one.

Step 4: Use the Correct Fire Extinguisher

A wet chemical Class K extinguisher is the correct tool for cooking media, and a multipurpose Class ABC unit works on a grease fire too because ABC covers Class B flammable liquids. In US practice cooking oils are Class K; if a page tells you to buy a Class F extinguisher, that is European terminology, not a mistake on your part.

Stand six to ten feet back with your exit behind you. Remember PASS: Pull the pin, Aim at the base of the flames, Squeeze the handle, and Sweep side to side across the bottom of the pan where the fuel is burning. A burst of powder across the flame tops does nothing.

Spray from the side rather than straight down, so the discharge does not knock hot grease out of the pan toward you. If the fire is not visibly out within a few seconds of one burst, stop and get out.

Step 5: Evacuate and Call for Help

Fire services teach a simple escape sequence, RACE: Rescue anyone in immediate danger, Alarm the household and pull the alarm, Contain the fire if it is safe, and Extinguish only if you are trained or leave. For a grease fire that has grown past a single pan, Contain and Extinguish turn into a full evacuation.

When you call 911, say the word fire first, then the address, then grease or cooking oil, then whether anyone is hurt and whether you are outside. Do not re-enter the house. Warn everyone else in the building and let the fire department handle it from there.

Some grease fires are not in a pan, and each has its own playbook. For an oven fire, turn the oven off and keep the door closed; opening it feeds the fire a fresh supply of oxygen, and you will meet a wall of smoke. For a microwave or air fryer, keep the door shut, switch it off, and unplug it only if you can do that without opening the door. For a deep fryer, a countertop unit, or a wok too wide to cover, kill the gas or power, slide a metal sheet over the top if you are within reach, and never carry it anywhere. A countertop fryer holds far more hot oil than a skillet, and moving it is how a bad fire becomes a burned-down kitchen.

And if grease has already spattered onto the range hood, backsplash, or cabinet fronts, that is no longer a pan fire. Cut the power if you can do it without passing the flames, and get out. One r/tifu account describes peanut oil throwing up a cook’s arm and across the stove, wall, and counters in the seconds before it ignited, which is why splatter on vertical surfaces should end the fight immediately.

Common Mistakes That Make a Grease Fire Worse

Almost every kitchen fire that gets out of hand starts with one of these. Each has a simple fix, which is really just the absence of the mistake.

• Water, in any form. Water sinks below the oil, flashes into steam, and expands roughly 1,700 times in volume, throwing burning grease across the ceiling. Broth, wine, and a wet dish towel do the same thing. Fix: never, under any circumstances, use a liquid.
• Flour, baking powder, or sugar. Airborne starch ignites almost instantly, and sugar caramelizes into a fuel. Fix: keep these off the counter next to the stove.
• A wet or dry towel. A wet towel spreads burning grease across the surface. A dry towel catches fire in your hand. Fix: nothing fabric, ever.
• Carrying the pan outside. This is the most common instinct after a pan fire and the one most likely to end in a burn. Fix: cover the pan where it sits.
• A glass lid. It shatters. Fix: metal only, and a baking sheet if the pan is wide.
• The wrong extinguisher, or a water-filled one. A Class A water extinguisher on a grease fire sprays a jet of water into hot oil. Fix: read the label and confirm the B or K rating before you buy.
• Lifting the lid to check. That is the step people most often skip, and the one that puts them back in danger. Fix: leave the cover on until the pan is cool to the touch.
• Waiting to see if it goes out on its own. A grease fire can flare up hard from a pan of cooling oil, and fuel vapor can travel to an ignition source across the room. Fix: act now or leave now.

A few habits remove most of the risk before it starts. Keep the oil below its smoke point, which is the temperature where the oil starts smoking and gives off flammable vapor; once you see smoke, back the heat off. Thaw frozen food in the refrigerator rather than dropping it into hot oil, and dry surface moisture off anything you fry, because water in hot oil spatters violently. Do not crowd a pan or a fryer basket, since more food means more oil temperature drop and more steam. Change oil when it darkens, thickens, or smells stale. Keep the range hood filter and the grease filter on the hood itself clean, since built-up grease is fuel. And never leave a burner on unattended, not even for a minute.

After a small fire is out, leave the lid in place until the pan is completely cool, then open windows and run the range hood to clear smoke. Wait for the oven to cool fully before cleaning it, remove loose debris by hand, and wash the racks and interior with hot soapy water or a paste of baking soda and water. Skip aerosol oven cleaner on anything that may still hold heat. A pan with scorched oil is usually still usable; one with a warped or blistered base is not, and no cleaning fixes soot baked onto glass.

Frequently Asked Questions

Turn off the burner, slide a metal lid over the pan from the side, and leave it until the pan is cool. If the fire is more than that, get out and call 911. Everything else, including baking soda, is a distant second to a metal cover and a clear exit route.
