How Wet Chemical Extinguishers Work?
A wet chemical fire extinguisher contains a potassium-based solution that attacks the fire in two ways:
1st the mist cools the fire and lowers the temperature to stop the fire spreading, also prevents splashing of the hot oils/fat.
Second, 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.
Kitchen-type wet chemical fire extinguishers discharge a fine mist that reacts with hot cooking oils and fats to form a soapy, non-combustible foam barrier (the saponification process described above). Some cleanup of this residue is typically required after use. These K class fire extinguishers are designed in a way to provide quick and targeted action during a kitchen fire.
