# A Grease Fire on the Cooktop: Four Things, In Order

## How to put out grease fire on stove: this page is instructions, not an article

There is nothing to explain and nothing to sell. The searches exist, the wrong answer kills people, and the right answer fits on a card.

**Never water.**

**Cut the heat. Cover the pan. Leave it covered. Get out if it has left the pan.**

## Why never water

Water is denser than burning oil and boils at a far lower temperature. Poured onto a pan fire it sinks, flashes instantly to steam, and expands several hundred times its volume — throwing the burning oil up and out as it goes.

A cup of water on a pan of burning oil produces a fireball that reaches the ceiling. That is not a caution; it is what happens, every time.

The same applies to a wet cloth, to a damp tea towel, and to anything else with water in it.

## In order

**1. Cut the heat.** At the knob, if you can reach it without putting your hand or arm through the plume. If you cannot reach it safely, skip this and go to step two — smothering matters more than the knob.

**2. Cover the pan with metal.** A saucepan lid, a frying pan lid, a baking sheet. **Slide it on from the side**, keeping your hand behind and below the flames, and **leave it there**. Do not drop a lid on from above: it pushes air out and can carry burning oil with it.

**3. No lid? Smother it.** Baking soda or salt, in quantity, poured from as far back as you can manage. Not a small sprinkle — enough to blanket the surface.

**Never flour.** Flour is combustible; it is a dust explosion waiting to happen and it will make things dramatically worse.

**4. Leave it covered for twenty minutes.** Oil that has been burning is above its auto-ignition temperature. Take the lid off after two minutes and it restarts without needing a flame.

## What not to do, ever

**Do not move the pan.** Not to the sink, not to the door, not out onto a terrace. Carrying a burning pan is how people receive serious burns and how a hob fire becomes a house fire. The pan stays where it is.

**Do not fan it, blow on it or beat at it** with a cloth. All three feed it air and spread it.

**Do not turn the hood on.** The instinct is to clear the smoke. What you are doing is pulling flames into a duct lined with years of grease, which is the one path out of the kitchen you least want a fire to find.

## When to stop and leave

If the fire has **left the pan** — flames in the hood, on the wall, on a cabinet, anywhere other than inside the pan — the answer is not a technique. Get everyone out, close doors behind you, and call **911 from outside**. Do not go back for anything.

The same applies if you are simply not certain. Standing next to a spreading fire to try one more thing is the decision that turns an insurance claim into an injury.

## A grease fire in the oven

Different, and simpler, and the instruction runs against instinct:

**Turn the oven off. Keep the door shut.**

A closed oven cavity starves a fire of oxygen and contains it. Opening the door gives it air and lets it out into the room.

On a Château vaulted gas oven this is easier advice to follow than on most appliances, because there is no window in the door to tempt you into looking. Turn it off, leave it shut, and let it go out.

If smoke is coming out around the door, or it does not subside within a few minutes, leave and call 911.

## What this range changes

Three things, and they are worth knowing before there is a fire rather than during one.

**A 22,000 BTU power burner** puts a great deal of energy into a pan very quickly. Oil gets to its smoke point faster than people expect, and from smoke point to ignition is not far. That burner is not the one to leave a shallow pan of oil on unattended.

**A lava-rock grill** is fat dripping onto a bed of rock over a lit linear burner. Flare-ups are part of how it works, and a saturated rock bed makes them dramatically worse because the rock holds fat and gives it back all at once. Replacing the rock bed once a year is a fire-safety measure as much as a cooking one.

**A 600 CFM hood** with baffles that have not been cleaned in a year has a duct lined with grease and a canopy full of it. That is the fire path out of the kitchen. Cleaning baffles every four to six weeks is not only about extraction.

## Afterwards

Once it is genuinely out and cold: do not use the range until somebody has looked at it. A grease fire heats things that were never meant to see that temperature — wiring behind a fascia, a knob bezel, a seal, the underside of a hood — and the damage is usually where you cannot see it.

Photograph everything before you clean up. It matters for insurance, and it matters for us.
