Wet Chemical Fire Extinguishers

Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats suitable for use in professional kitchens. Wet chemical fire extinguishers gently spray out a fine mist of potassium salts to prevent spreading the fire, this creates a soapy film on the surface of the substance which smothers the fire and creates a cooling effect. Wet chemical extinguishers can be identified with a yellow label stating wet chemical.
