Wet Chemical Fire Extinguishers
A wet chemical fire extinguisher is used to tackle class F fires such as fat, oil and grease fires in kitchens. All of our wet chemical fire extinguishers can also be used to tackle class A fires and fires involving live electrical equipment, making them ideal for use in a kitchen environment. 2ltr or 3ltr wet chemical extinguishers are suited to domestic kitchens, small commercial kitchens or catering vans. A larger commercial kitchen or one that had large quantities of oil, for example in deep fat fryers, would require a 6ltr wet chemical extinguisher.
Wet chemical fire extinguishers are often paired with fire blankets for complete coverage for kitchen fires.

Which fire extinguishers are suitable for kitchen fires?
Kitchen fires caused by cooking oil and fats are Class F fires, and must only be tackled by extinguishers which have been certified for this use. Wet chemical extinguishers are designed to fight Class F fires by forming a blanket on top of burning materials to suffocate and then cool the blaze. These extinguishers should be installed in areas such as kitchens and garages where this type of fire is a common risk. Some other extinguishers, such as some Water Mists, may have small F ratings for use in home kitchens.
WARNING: Using the incorrect extinguisher on a Class F fire may splash burning oil, causing the fire to spread.
How do wet chemical extinguishers work?
The extinguishing agent used in wet chemical extinguishers expands upon contact with the burning oil to form a blanket on top of it, which prevents re-ignition by cooling and smothering the area as well as blocking access to oxygen. They are usually supplied with a long lance which helps the user keep a safe distance from the fire and deploy the foam at low pressure, rather than 'spraying' the deep fat fryer which risks causing splashes and spreading the fire on burning droplets of oil.
It is important that the full content of the wet chemical extinguisher be discharged even after the flames have been extinguished, to ensure the oil or fat remains blocked from oxygen until it has cooled enough to prevent reignition.
Can water mist extinguishers be used on cooking oil fires?
Some small Water Mist extinguishers are certified for use on cooking oil fires. These extinguishers have a small Class F rating to demonstrate that they are effective at fighting a small, domestic kitchen fires. For example, a 5F rating suggests that an extinguisher could be used to fight a fire involving up to 5 litres of cooking oil, making them ideal for most home kitchens. For catering premises or deep fat fryers, a wet chemical extinguisher should be installed: wet chemical agent can be effective on fires involving much larger quantities of cooking oil.
How do water mist extinguishers work?
The Water Mist extinguishers' supersonic nozzle creates a microscopic mist curtain which reduces the oxygen content (required for combustion) around the fire, extinguishes the flames and creates a highly effective cooling blanket on the hot fuel, preventing re-ignition.
While water should not be used to extinguish an oil fire due to the risk of splashing and vaporization, Water Mist is effective against small cooking fires up to 5F (typical household deep fat fryer) due to the design of its nozzle.
Which fire extinguishers are used for kitchen fires?
Wet chemical fire extinguishers are used for kitchen fires as they are designed to tackle class f fires (fires involving cooking oils or fat). Most wet chemical fire extinguishers are also rated to tackle class A fires and fires involving live electrical equipment, making them suitable for all common kitchen fire risks.
The main fire risks found in kitchens usually involve cooking oil, fat or a build-up of grease. This type of fire is referred to as a class F fire. Kitchen fires also often involve live electrical equipment such as an electric hob, oven or microwave and class A materials such as fabrics, plastic or wood. As wet chemical extinguishers are suitable for tackling all of these fire types, they are ideal for use in and around kitchens in a commercial environment or at home.
