Wet Chemical Fire Extinguishers

A wet chemical fire extinguisher is specifically designed to suppress fires involving cooking fats and oils.

Unlike other extinguishers, which may struggle to contain high-temperature grease fires, wet chemical extinguishers work by cooling and smothering the flames while also preventing re-ignition.

Key Features of Wet Chemical Extinguishers:

Primary use: Suitable for Class F fires (cooking oils and fats).
Secondary use: Can also be effective on Class A fires (combustible materials like wood, paper, and textiles).
How it works: The extinguisher releases a potassium-based solution that reacts with the burning oil or fat, forming a soapy layer (saponification) that cuts off oxygen and cools the fire.
Sizes available: PLS Fire & Safety offer 2L &, 7L, extinguishers
