Much like the water type, Foam fire extinguishers can be used for fires involving organic materials. In addition to these organic materials, foam extinguishers can also be used on flammable liquids including petrol or paint. Foam fire extinguishers work in two ways. Firstly, they create a cooling effect on the fuel that is responsible for causing the fire.
Secondly, when this extinguisher is used on burning liquids, the foaming agent inside the extinguisher Aqueous Film Forming Foam creates a barrier between the flames of the fire and the fuel. This ultimately extinguishes the fire.
Foam fire extinguishers are required for buildings where flammable liquids are stored and held. In addition to this, they are also required in buildings where organic materials are found.

Carbon dioxide fire extinguishers are the primary extinguisher used in extinguishing electrical fires.
You will often find CO2 extinguishers in computer server rooms or areas where a large number of electrical devices exist. The CO2 extinguisher can be used to extinguish electrical fires and fires involving flammable liquids such as petrol.
This type of fire extinguisher works by suffocating the fire with CO2, causing the oxygen to be displaced and the fire to burn out. The wet chemical fire extinguishers are used for Class F fires.
Class F Fires involve cooking oils and fats. Whilst this type of fire extinguisher can be used in Class A fires, it is recommended that you have a foam or water extinguisher to tackle a fire that fits into this class. This type of fire extinguisher works by creating a layer of foam on the surface of the burning oil or fat that starves the fire of oxygen.
The chemical that is contained within the extinguisher is potassium and upon pressing the trigger, the potassium is expelled as a fine mist. The potassium reacts with the oil or fact and creates a soapy like film on the surface of the fire. The spray itself also has a cooling effect that helps to eliminate the fire.
