Such fires should be extinguished with a wet chemical extinguisher.

The new Amerex KP system and Amerex Model 260 Wet chemical extinguisher provides restaurants with a two step attack against the threat of business loss due to kitchen fires (The new Class F).

F class fires are included as a class of their own to allow for the Wet Chemical extinguisher which is particularly effective against fires involving cooking fats and oils, but is not suitable for other flammable liquid type fires (B class).

On fire tests carried out on cooking oil fires both the 3 Litre and the 6 Litre Wet Chemical extinguishers, extinguished a 75 Litres cooking oil fire in accordance with the standards set out by the British Standards Institute.

There is no official standard in the United States for the color of fire extinguishers, though they are typically red, except for class D extinguishers which are usually yellow, water and Class K wet chemical extinguishers which are usually silver, and water mist extinguishers which are usually white.
