Grease fires are among the most dangerous fires in the home – and they can start in seconds. Whether you're frying, deep-frying, or cooking with fat, it's extremely important to know how to react when a grease fire breaks out. Many people make mistakes in such situations because they panic or don't know what really helps. In this guide, we'll show you step by step how to safely extinguish a grease fire – and, more importantly, how to prevent it from happening in the first place.

How does a grease fire start?
A grease fire occurs when oil or fat is overheated and ignites. Unlike water, which simply evaporates when heated, oil can reach a temperature at which it catches fire. Once this happens, the fire spreads extremely quickly – and is almost impossible to extinguish if you don't know the right method.
Typical causes of grease fires:
- Do not leave oil unattended while cooking.
- Using too much oil or fat at once.
- Heat the oil beyond its smoke point.
- Dripping fat on stovetops or open flames.
The most important tip for prevention: Never leave hot oil unattended and always keep an eye on the temperature. It's best to use a thermometer – that way you stay within the safe range for your recipe.

What you absolutely must not do in case of a grease fire
When a grease fire suddenly breaks out, many people react rashly – and make it even worse. You absolutely must avoid these mistakes:
-
Never use water! Pouring water onto burning fat sounds logical, but is extremely dangerous: The water evaporates immediately, flings the burning fat apart – and the flames shoot up explosively.
-
Do not move the pan! Even if it's tempting to carry the burning pan outside – even a single spilled drop of fat can spread the fire further. Extinguish the fire directly where it started.
- Do not use the wrong fire extinguisher! Ordinary extinguishers are unsuitable and will only spread the burning grease. Use only a grease fire extinguisher (fire class F) – or follow the steps below.

How to properly extinguish a grease fire
If a grease fire breaks out in your kitchen, proceed as follows:
-
Turn off the heat source. Immediately turn off the stove or flame to prevent any further heat from being added.
-
Smother the flames. Carefully place a metal lid or baking tray over the pan to smother the flames. This deprives the fire of the oxygen it needs. Glass lids are a no-go – they can shatter from the heat.
-
Use baking powder or salt. For small fires, you can generously sprinkle baking powder or salt onto the flames – this will smother them. Caution: Do not use flour or other powders, as these can catch fire themselves!
-
In an emergency, get out and call for help. If the fire spreads or gets out of control, leave the apartment immediately and call the fire department. Your safety always comes first – never try to fight a large fire alone.

How to avoid grease fires from the outset
The safest approach is to prevent a grease fire from starting in the first place. With a few simple precautions, you can significantly reduce the risk.
Prevention tips:
- Check oil temperature: Use a thermometer to ensure the oil is not heated above its smoke point.
- Choose the right pan size: Never fill it with too much oil – otherwise it can easily overflow.
- Keep flammable materials away: Never leave kitchen paper, wooden spoons or other flammable items near the stove.
- Always stay alert: Never leave the stove unattended when cooking with oil or fat.
