Wet Chemical fire extinguishers are the most effective against Class F fires (cooking oils and fats) e.g fats, grease and oil. Therefore they are practical in a kitchen environment.
Use the a Class K Fire Extinguisher
The best fire extinguisher for a grease fire is a Class K. These are wet chemical extinguishers commonly found in commercial kitchens. They are designed specifically for cooking fires and work by forming a soapy foam on the surface of the fire that cuts off air flow.
Class F fire extinguishers are the most suitable extinguisher for cooking oil fires. They are equipped with a special type of foam that forms a crust which smothers the fire and deprives it of oxygen.
Wet Chemical fire extinguishers are the most effective against Class F fires (cooking oils and fats) e.g fats, grease and oil. Therefore they are practical in a kitchen environment.
According to NFPA 10, Standard on Fire Extinguishers, a Class K portable fire extinguisher is defined as an extinguisher that is designed to extinguish fires involving animal fats or cooking oils.
The method that can be used to put out an oil fire is using a carbon dioxide fire extinguisher.
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.
Raising the plume: a metal casing 30 to 40 feet high is placed over the wellhead (thus raising the flame above the ground). Liquid nitrogen or water is then forced in at the bottom to reduce the oxygen supply and put out the fire.
Water should never be used to extinguish oil fires. Which option provides the best justification for this statement? Water is heavier than oil. On spraying water, it sinks and oil floats, and the fire continues.
Fire extinguishers containing CO2 are the best extinguishers for fires involving electrical equipment: because CO2 being heavier than oxygen increases fire. because CO2 being lighter than oxygen covers the fire like a blanket. because CO2 being heavier than oxygen covers the fire like a blanket.
Foam blankets the flammable liquid, effectively smothering it by creating a physical barrier that starves it of oxygen. Simultaneously, it extracts heat from the liquid and surrounding surfaces.
Class B extinguishers are used on fires involving flammable liquids, such as grease, gasoline, oil, and oil-based paints.
Pour on Baking Soda - Baking soda will extinguish grease fires, but only if they're small. It takes a lot of baking soda to do the job. Spray the Pot with a Class B Dry Chemical Fire Extinguisher - This is your last resort, as fire extinguishers will contaminate your kitchen.
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.
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.
Carbon dioxide fire extinguishers are ideally used in electrical rooms, elecitrcal/ electronic equipment rooms and archives. It is because after spraying nothing is left behind. You will not find any trace. Dry powder fire extinguishers are ideal for taking out Class A, B and C types of fires.
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.
