Wet Chemical Fire Extinguisher - China

A wet chemical fire extinguisher is easily identifiable by its cream or oatmeal-colored label (in the UK/EU) or its yellow label with a "K"in the United States.

It contains a pressurized, alkaline solution, typically potassium acetate or potassium citrate, which is discharged as a fine mist to safely suppress dangerous cooking oil fires.

How Does a Wet Chemical Fire Extinguisher Work?

The effectiveness of a wet chemical extinguisher lies in a two-stage attack and a unique chemical reaction:

1 - Cooling: The fine mist agent cools the burning oil rapidly, reducing its temperature below the ignition point.

2 - Saponification (The Key Feature): ** This is the critical process.

The alkaline chemical reacts with the hot cooking fat or oil to form a thick, soapy foam layer on the surface.

This foam:

*Smothers the fire by cutting off its oxygen supply.

*Prevents re-ignition by creating a lasting seal over the hot oil, even after the flames are out.

What is a Wet Chemical Fire Extinguisher Used For?

Wet chemical extinguishers are classified for specific fire types:

* Class K Fires (US) / Class F Fires (EU/UK): Primary Use.

These are fires in commercial cooking appliances involving **combustible cooking oils, animal fats, and greases.

Examples include fires in deep-fat fryers, griddles, and range tops.

* Class A Fires: Secondary Use.

They can also be effective on fires involving ordinary combustibles like **wood, paper, cloth, and plastics** due to the cooling effect of the agent.

Where to Use a Wet Chemical Extinguisher

You will find these extinguishers installed in areas with high-temperature cooking equipment:

* Commercial Kitchens (Restaurants, Hotels, Food Trucks)

* Hospital and School Cafeterias

* Catering Facilities

* Bakeries with industrial fryers

* Any location with a commercial deep-fat fryer

They are always placed near exits and within easy reach of the cooking appliances, but at a safe distance to be accessible if a fire occurs.

How to Use It: The P.A.S.S. Method

Always follow the P.A.S.S. technique** for safe and effective use:

1 - PULL the safety pin to break the tamper seal.

2 - AIM the nozzle or hose low, at the base of the fire.

Aim at the edge of a fryer to avoid splashing oil.

3 - SQUEEZE the handle to release the extinguishing agent.

4 - SWEEP the nozzle from side to side, covering the entire fire area.

Apply the agent slowly for the saponification process to work.

What is the colour code for a wet chemical fire extinguisher?

In the UK, Australia, and Europe, the body is red, but it has a cream or oatmeal-colored rectangular panel on it.

In the US, it has a yellow label.

Can you use a wet chemical extinguisher on an electrical fire?

*No.

The agent is water-based and conductive, posing a severe risk of electric shock.

For electrical fires, you should use a **CO2 fire extinguisher**.

What is the difference between wet chemical and dry chemical extinguishers?

* Wet Chemical: For Class K/F (cooking oils) and Class A fires.

Uses a liquid agent that cools and creates a soapy foam.

* Dry Chemical (ABC): For Class A, B, (flammable liquids), and C (electrical) fires.

Uses a powder that interrupts the chemical reaction of the fire.

It is not suitable for deep-fat fryers as it does not prevent re-ignition.
