Wet chemical extinguishers are designed primarily for fires involving cooking oils and fats, often referred to as Class F fires. They are commonly installed in professional kitchens and food preparation environments where these types of fires are most likely to occur.

How can I identify a wet chemical fire extinguisher?

A fire extinguisher with a yellow label indicates a wet chemical extinguisher. The yellow colour coding helps users quickly identify the correct extinguisher type in an emergency, particularly in kitchen environments where several extinguisher types may be present.

Where should wet chemical fire extinguishers be installed?

Wet chemical fire extinguishers are typically installed in commercial kitchens, restaurants, catering facilities, and other food preparation areas. They may also be positioned in shared kitchens within office buildings, hospitals, and hospitality venues where cooking equipment is used.

Are wet chemical fire extinguishers only used in restaurants?

While they are most commonly associated with restaurants and commercial kitchens, wet chemical extinguishers may also be required in hotels, workplace cafeterias, healthcare catering areas, and food production facilities. Any environment where cooking oils and fats are used may require a chemical fire extinguisher.

How often should wet chemical fire extinguishers be serviced?

Like other fire safety equipment, wet chemical fire extinguishers should be inspected regularly and professionally serviced at least once a year to ensure they remain operational and compliant with fire safety standards.

Can wet chemical extinguishers be used on other types of fires?

Some wet chemical fire extinguishers are also rated for certain Class A fires involving materials such as wood or paper. However, they are specifically designed for kitchen related fire risks, so the correct extinguisher type should always be chosen based on the hazards present.

Why are wet chemical fire extinguishers important for commercial kitchens?

Cooking oils and fats burn at very high temperatures and can spread quickly if handled incorrectly. Wet chemical fire extinguishers are specifically designed to tackle these fires safely, helping protect people, equipment, and the building.

Wet chemical fire extinguishers

Wet chemical extinguisher products, or foam from extinguishers, will vaporise from the heat in cooking fires, but the gentle application of a wet chemical solution, via a mist type nozzle and extended lance, creates a layer which starves the fire of oxygen. When using a wet chemical fire extinguisher, the entire contents of the unit should be deployed to help cool the solution and prevent re-ignition.

At TVF, we can supply, install, and maintain wet chemical fire extinguishers for businesses local to us in High Wycombe, Watford, and Slough. We’re also backed by the LS Fire Group, meaning we can provide our services nationwide with the help of our partner brands.

What is a wet chemical fire extinguisher used for?

Spraying a wet chemical mist onto the fire to suppress the flames, wet chemical fire extinguishers are crucial in fighting Class A, B, and F fires. These fire extinguishers are ideal for kitchens, restaurants, and other cooking environments where fat or oil fires are likely, as they avoid splashing and spreading the liquid.

Wet chemical extinguishers have a yellow label and can be used as a Class A fire extinguisher, Class B fire extinguisher, or a Class F extinguisher.

It’s important to note that not all wet chemical fire extinguishers will be suitable for B Class fires, so be sure to check the front label on the extinguisher, or speak to a professional for guidance.
