Fires can start anywhere in a building, but kitchen fires are among the most common and dangerous. Spills of oil, pans that get too hot, bad wiring or a cooker that is left on can quickly become a big problem. Knowing which fire extinguisher to use in the kitchen can help you put out a minor fire before it spreads.
In this guide, you’ll understand which type of fire extinguisher is best for kitchens, how different fire types are classified, and what to avoid when dealing with kitchen fires.
Understanding Fire Classes in Kitchens
The first thing you need to know when picking the correct fire extinguisher is what kind of fire you’re dealing with. Fires are grouped into different classes based on the material that’s burning.
Class A, B, C, and F fires are the most prevalent in kitchens.
- Class A flames are ones that have solid materials in them, such wood, cloth, or paper.
- Flammable substances like frying oil, fuel or grease can start Class B fires.
- Gases like LPG start Class C flames.
- When frying fats or oils catch fire, especially at high temperatures such in deep fryers, this is called a Class F fire (or Class K in some countries).
Most kitchen fires involve oils and fats, which are very different from normal fuel fires. Throwing water on such fires can make things worse, as it causes the burning oil to splash and spread the fire. That’s why choosing the right fire extinguisher is extremely important.
The Best Fire Extinguisher for Kitchen Fires
When it comes to kitchen fires, the best type of fire extinguisher to use is the wet chemical one. It’s made specifically for Class F fires, which usually involve things like cooking oil or grease.
There are two ways that wet chemical extinguishers function. First, they put out the fire. Second, they make a soapy coating on top of the oil that keeps oxygen out and blocks the fire from starting again. People call this saponification. Most of the time, these extinguishers come with a long hose so that the user may spray the chemical from a safe distance.
You can come across this kind of fire extinguisher at restaurants, commercial kitchens, and places where food is processed. But a lot of households are increasingly keeping them in their kitchens as well, especially if they use deep fryers or cook with oil a lot.
Can You Use Other Fire Extinguishers in a Kitchen?
While wet chemical extinguishers are the best for cooking oil fires, other types of extinguishers can also be useful in certain kitchen situations. Here’s how they compare:
Foam can put out Class A and B flames, which means it can put out burning paper, fabric, or liquids that catch fire easily. But foam isn’t safe for kitchen oil fires, especially those produced by deep fryers. It could not cool the oil down right and could be harmful if used wrong.
Carbon Dioxide (CO₂) Fire Extinguishers:
These work well on electrical fires, such those that can be caused by kitchen appliances. CO₂ displaces oxygen and cools the area. It doesn’t work well on oil fires, but it doesn’t leave any residue, so it’s great for keeping electronics safe.
Dry Powder Fire Extinguishers:
These extinguishers are multi-purpose and can be used on Class A, B, and C fires. They are helpful in houses where the kitchen could also feature gas equipment. Although dry powder can make a big mess and shouldn’t be used in small areas because it can make it hard to see and irritate the lungs.
Water-Based Fire Extinguishers:
This type of extinguisher works by releasing a steady stream of water that cools down the flames and reduces heat from burning materials. It’s best for tackling Class A fires, which usually involve everyday items like paper, cloth, or wood. You’ll often see these extinguishers in places like homes, schools, and offices because they’re simple to use and handle common fire situations well. But they’re not safe for fires that involve cooking oil, grease, or anything electrical, as using water in those cases can make things worse.
Tips for Placing Fire Extinguishers in Kitchens
Placing a fire extinguisher correctly is just as important as owning the correct one. When choosing a place for your fire extinguisher, bear these points in mind:
- Don’t put the extinguisher too close to the stove or fryer; keep it near the door. This enables you to get away if the fire gets out of control.
- Put the fire extinguisher on a wall where it can be seen at shoulder height.
- Make sure that everyone who works for you or lives with you knows where it is and how to use it.
- Check the extinguisher often to make sure it isn’t broken or obstructed.
What Not to Do During a Kitchen Fire
Knowing what not to do during a kitchen fire is just as important as knowing how to use an extinguisher. One of the biggest mistakes people make is throwing water on a grease fire. Water causes the burning oil to splatter and spread, increasing the fire.
Another common mistake is trying to move a burning pan or deep fryer. This can cause burns or allow the fire to spread to curtains, shelves, or plastic items. Always turn off the heat and use the correct extinguisher. If the fire is growing quickly or if you are unsure, evacuate and call emergency services.
How to Use a Fire Extinguisher
Using a fire extinguisher properly can save lives and prevent further damage. The basic technique used across most types is known as the PASS method:
- Pull the safety pin
- Aim the nozzle at the base of the fire
- Squeeze the handle
- Sweep from side to side
Practice this process mentally so that if a fire ever happens, you’ll know how to respond quickly.
Maintenance and Expiry
Many people forget that fire extinguishers require maintenance. An unused fire extinguisher can still lose pressure over time. Most extinguishers have a pressure gauge—if the needle is not in the green zone, it may not work.
Fire extinguishers also have expiry dates. A basic dry powder extinguisher can last 5–10 years. Wet chemical extinguishers also need periodic servicing to stay effective. Commercial kitchens should get their extinguishers checked by professionals every year.
Conclusion
Having the right fire extinguisher in your kitchen can save lives, protect property, and keep small incidents from turning into disasters. For most kitchens, a wet chemical fire extinguisher is the safest and most effective option. But having other types, like CO₂ or dry powder extinguishers, can provide extra protection against electrical and gas-related fires.
