Frequently Asked Questions

What Is A Wet Chemical Fire Extinguisher?

A wet chemical fire extinguisher is a type of fire extinguisher that is specifically designed to extinguish fires caused by cooking oils and fats. It contains a special chemical agent that reacts with the hot oil or fat to create a soapy foam, which cools and smothers the flames. Wet chemical fire extinguishers are typically identified by their yellow color and are commonly found in commercial kitchens and other food service areas.

What Is A Wet Chemical Fire Extinguisher Used For?

A wet chemical fire extinguisher is primarily used for extinguishing fires that involve cooking oils, fats, or other organic liquids. It works by creating a barrier between the fuel and the oxygen in the air, thus preventing the fire from spreading. Wet chemical extinguishers are often found in commercial kitchens or areas where cooking takes place.

How Does A Wet Chemical Fire Extinguisher Work?

A wet chemical fire extinguisher works by spraying a solution of potassium acetate onto the fire, which creates a barrier between the fuel and the oxygen, effectively extinguishing the flames. This type of extinguisher is specifically designed for Class F fires, which involve combustible cooking oils and fats commonly found in kitchens. The wet chemical agent also has a cooling effect that helps prevent re-ignition of the fire.

How Do You Use A Wet Chemical Fire Extinguisher?

Using a wet chemical fire extinguisher is a simple process, but it’s important to be familiar with the steps before an emergency situation arises. Here’s how to use a water fire extinguisher:

Call the fire brigade: In any case of fire, it’s always a good idea to call the fire department, even if you think you’ve put the fire out.

Pull the pin: To release the locking mechanism and activate the fire extinguisher, pull the pin at the top of the unit.

Aim the nozzle: Point the nozzle of the fire extinguisher at the base of the fire, not at the flames.

Squeeze the handle: Firmly squeeze the handle of the fire extinguisher to release the foam.

Sweep the nozzle: Sweep the foam over the surface of the fire in a sweeping motion, starting at the base of the fire and working your way up.

Keep a safe distance: Stand a safe distance away from the fire and make sure to keep the fire extinguisher aimed at the fire.

Monitor the fire: After using the fire extinguisher, monitor the fire to make sure it’s completely extinguished and does not re-ignite.

It’s important to remember that foam fire extinguishers should only be used on Class A and never on electrical fires. Before using a fire extinguisher, it’s also a good idea to assess the situation and make sure that it’s safe to do so. If the fire is too large or spreading too quickly, it’s best to evacuate the building and call the fire brigade.
