Silver class K fire extinguishers are meant exclusively to handle kitchen grease fires. They utilize a foam-forming agent that prevents persistent kitchen fires from reigniting.
For home kitchens, the best type of fire extinguishers is one that is for class A and class B fires, and more importantly is both easy to use and right at hand. Class B fires are oils, greases, and other hydrocarbon fuels. Class A fires are almost everything else except metals and electrical.
Yes, you can use an ABC fire extinguisher in the kitchen, but it may not be as effective on grease fires as a Class K extinguisher, which is specifically designed for that purpose.
When it comes to kitchen fires, it's recommended to use a fire extinguisher specifically designed for Class K fires. These extinguishers are designed to combat fires involving cooking oils, fats, and greases commonly found in kitchens. They use a special extinguishing agent that helps smother and cool the fire.
In the hands of a trained user, a CO2 fire extinguisher could be used on a class B fire (flammable liquids like petrol or oil) but should never be used on cooking fires because its powerful discharge could easily splash burning fat and fan the fire.
Class K extinguishers are filled with an agent designed to prevent burning grease from splattering and spreading. These types of fire extinguishers are the ones most often found in home kitchens. Since most kitchen fires are small and in a tight area, Class K fire extinguishers use a high-volume, low-velocity spray.
Carbon dioxide fire extinguishers, when used in the right circumstances can save lives. However, it would be dangerous to use a carbon dioxide fire extinguisher when dealing with flammable gases, cooking oils and fats, or in a confined space.
Dry chemical fire extinguishers are not sufficient to put out kitchen fires involving vegetable-based cooking oils, which carry a high risk of re-flash fires. These extinguishers should be removed from the cooking area.
The National Fire Protection Association (NFPA) provides minimum recommendations for the home: Primary Fire Extinguishers - For your main home protection, install a 2-A:10-B:C rated extinguisher on every level of your home - no more than 40 feet apart. Include all locations where a fire may start.
It's important to note that while ABC extinguishers are versatile, they are not suitable for fires involving cooking oils and fats (Class K fire extinguishers are suited for this) or combustible metals.
ABC extinguishers are not appropriate for metal fire or class D fires because they combine a projectile blast from the extinguisher with an agent it is incompatible with. This will spread and intensify the fire. Researchers are responsible for following best practices to prevent laboratory fire and prepare for them.
Easy and safe access aside, placing the fire extinguisher at the entrance of the kitchen also allows everyone in the household to have a quick check on the pressure gauge whenever they head to the kitchen.
In a hospital kitchen or dietary area, you would typically expect to find a Class K fire extinguisher. This class is specially designed for fires involving cooking oils, fats, and greases, which are common in kitchens.
Standard dry powder fire extinguishers are very versatile and can put out virtually every kind of fire. However, they aren't recommended for use in enclosed spaces. See the link for a full article explaining the correct use of fire extinguishers in confined spaces.
Wet chemical fire extinguishers are ideal for Class F fires, involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter.
As a good rule of thumb, you should plan to replace your disposable fire extinguisher every 12 years. If you aren't sure how old your extinguisher is then you can check the pressure gauge on a monthly basis to ensure it's still functional.
For a room of average dimension, a 5-lb fire extinguisher may be sufficient. For larger commercial spaces and warehouses where a fire has more room to spread, a larger 10-lb model may be necessary.
While ABC extinguishers are versatile and can combat a wide range of fires, CO2 extinguishers are specifically designed for electrical and flammable liquid fires. The choice between the two depends on the specific needs of the environment and the types of hazards one may encounter.

Fast and very effective, this extinguisher really works. Its powerful spray put out both the grease fire and the towel fire right away, though it left a big cloud of fumes each time.
Class F wet chemical fire extinguishers are designed for kitchen fires that occur in both domestic and commercial kitchens.
The answer is you can use either a dry powder fire extinguisher which has a blue coloured label,or a CO2 fire extinguisher which has a black label. Both fire extinguisher types are suitable to use on electrics which many people have in a kitchen so both are a good example to use if your toaster was to catch fire!
The average home should have a multi-purpose ABC-type extinguisher on each story of the home, plus an extinguisher (BC type) for the cooking area. BC-type extinguishers cause less damage to appliances and furniture finishes and are preferred for kitchens.
Homes: There's no reason you can't keep a 2kg CO2 fire extinguisher in your home. However, because so many home fires are started by cooking oil in the kitchen, it's not a favourite among homeowners. That being said, a CO2 extinguisher can still be used in any other part of the house, including the garage.
Class F fires should only be treated with a wet chemical fire extinguisher. This type has been tailored specifically to tackle fires caused by fat and oils because they contain potassium salts that work to reduce the heat and smother any oxygen feeding the fire.
For this reason, powder extinguishers should generally not be specified for use indoors, unless mitigated by a health and safety risk assessment. We hope this guide to what fire extinguisher should not be used in confined spaces has been helpful.
