Wet chemical fire extinguishers are designed to combat fires involving combustible cooking oils and fats, often found in kitchens or restaurants.

Wet chemical fire extinguishers contain a specially formulated extinguishing agent. This extinguishant, when dispersed, will react with oil to form a soapy substance. This process is called saponification. Saponification of the extinguishing agent will produce a cooling blanket which seals the surface of the fuel to prevent reignition and spreading.

The labels on wet chemical fire extinguishers are yellow, making them easy to distinguish from other types of extinguishers. The word 'wet chemical' will be printed in large white letters across the label.

Restaurants, fast food outlets, chip shops, kitchens and any business that uses oil or cooking fats.

All our portable fire extinguishers are supplied ready for use, but those with larger capacities may need to be filled and charged prior to the first time they’re used. The product listing will explain this clearly.
