Wet chemical fire extinguishers are a new innovation in the fire industry. Cooking appliances are the biggest single source of accidental fire in the workplace. With this in mind the wet chemical solution is the most effective means of extinguishing fires involving deep fat fryers. The solution cools and emulsifies when applied to burning fats and oils. This seals the surface and prevents re-ignition of the fire. Furthermore this new type of extinguisher also has A class fire rating.
Wet chemical extinguishers contain potassium salts which when sprayed on a fire create a film on the fire’s fuel. The fire is cooled and smothered by the film.
