When the agent reacts with the hot grease, it forms a layer of foam on the surface of the fat. This soap-like blanket of foam acts as an insulator between the hot grease and the atmosphere, helping to prevent flammable vapours from escaping and reducing the chance for flame re-ignition.


Wet Chemical Fire Extinguishers contains a solution of potassium which effectively attacks the flame in two methods:

Firstly the mist cools the fire and lowers the temperature to stop the fire spreading, also prevents
splashing of the hot oils/fat

Secondly the potassium salts react with the hot oil and causes the process of saponification, coating the surface of the cooking oil or fat in soapy foam that is non combustible and acts as a barrier between the fat and oil.
