Kitchen fire extinguishers

Wet Chemical Fire ExtinguisherFires in kitchens grow out of control quickly. Last year, they were responsible for 62% of all fires in the home. To ensure you’re equipped to fight kitchen fires, you’ll need a combination of fire extinguishers and a fire blanket.

Classes of fire

There are three types of fire you’re likely to encounter in the kitchen: • Class F fires • Class A fires • Electrical fires This sounds like a lot, but you will only need two multi-class extinguishers and a fire blanket to cover all risks. • Wet chemical (class A and F) • CO2 (class B and electrical)  

CO2 fire extinguishers

Class B (flammable liquids) and electrical risks. CO2 fire extinguishers are the only ones suitable for use on electrical fires – they don’t release any toxic agents and won’t damage surrounding devices. If your kettle, microwave, toaster or any other electrical appliance ignites, use your CO2 extinguisher. Do not use them on cooking fires; though they’re suitable for use on flammable liquids, this does not include cooking oils. Flammable liquids that they can be used on include spirits, petrol, diesel, oil based paints and the like.

Wet chemical extinguishers

Class F fires are ones that involve cooking fats and oils. They commonly occur in deep fat fryers, and the only extinguisher you should use on them is a wet chemical fire extinguisher. Wet chemical fire extinguishers release their agent at a very low velocity and have a gentle applicator lance to prevent splash backs. They contain an agent that reacts with burning oil to produce a soapy, non-combustible layer, a process known as saponification. Use any other extinguisher to fight a cooking fire, and you’ll simply spread the fire out further. Don’t forget that wet chemical extinguishers can also be used to fight class A fires – that’s fabric, furniture, paper, wood and the like.

Fire blankets

The only other firefighting tool you can use when tackling cooking fires is a fire blanket. They’re simple, but they’re a great addition to any kitchen as they’re so versatile. They can be draped over pans to fight cooking fires or wrapped around people to smother clothing fires.
