What kind of chemical is in a wet chemical fire extinguisher?

      The wet chemical agent inside a wet chemical fire extinguisher is typically a mixture of water, a surfactant (a substance that reduces the surface tension of a liquid), and an alkaline solution such as potassium acetate or sodium bicarbonate. This mixture is designed to be effective at extinguishing fires involving cooking oils and fats, as well as any accompanying fire that may have spread to surrounding surfaces.

     Wet chemical fire extinguishers are designed to extinguish fires involving cooking oils and fats, such as those that occur in deep fryers and other kitchen equipment. These extinguishers work by creating a layer of foam on top of the burning oil or fat, which smothers the fire and prevents oxygen from reaching the fuel. The foam also helps to cool the burning oil or fat, further reducing the risk of re-ignition.
