# A Grease Fire Inside the Oven: What to Do and What Not to Open

## What to do if grease fire in oven: leave the door shut

That is the answer, and it is the opposite of what almost everybody does.

## Why shut

An oven cavity is a **sealed steel box with a finite amount of air in it**. A fire inside it consumes that air and goes out.

Opening the door does two things at once, both bad: it gives the fire a fresh supply of oxygen, and it releases whatever is burning **outward, at face height**, toward the person who opened it.

Most oven fires are out within a minute or two of being left alone. Almost every serious injury from one involves the door.

## The sequence

- **Door stays shut.**- **Turn the oven off** at the control.- If you can reach it safely, **switch the circuit off at the breaker**.- **Watch through the glass.** Give it a minute or two.- If it is still burning strongly, or if flame is escaping around the door, **get everybody out and call the fire service from outside.**

## Three things not to do

**Do not throw water at it.** Water on burning fat turns instantly to steam and throws burning fat with it. This is true in an oven and it is true on a cooktop.

**Do not open it to look.** The glass is there for exactly this.

**Do not try to get the tray out.** Whatever is in the oven is already lost. Nothing in there is worth reaching into a fire for.

## Why the cooktop advice does not apply here

On an open cooktop, a pan fire is smothered — a metal lid, a baking sheet, a fire blanket — and baking soda works on a small one. All of that is about **cutting off the air**.

In an oven, the air has already been cut off. The cavity is doing the job. **You are not adding a lid; you are the person who might remove one.**

## Afterwards

Let it cool completely. Hours, not minutes — a cavity that has had a fire in it holds heat, and on many machines the door will stay locked until it has cooled anyway.

Then clean it out properly, and **have the appliance checked before using it again**. That is not an upsell. Heat that intense can:

- damage wiring behind the cavity, which is where a later burning-plastic smell comes from;- distort the door seal, so the oven never quite holds temperature again;- affect the temperature sensor, so it reads wrongly from then on;- trip a thermal cut-out that then trips early forever afterwards.

None of that is necessarily visible when you look inside.

## Preventing the next one

Spillage on the cavity floor is the fuel. Everything else is detail.

**Clean it out** — a self-clean cycle, or by hand with something that will not attack the coating.

**Use a tray under anything that might overflow**, particularly on a rack above another dish.

**Do not line the oven floor with foil.** It traps grease, it changes how heat moves through the cavity, and on several ovens it blocks the airflow the burner or element depends on. It is a common piece of advice and it is a bad one.
