The most effective and safest solution for extinguishing class A and B fires Foam fire extinguishers are extinguishing devices that use a foaming substance to smother and cool the flames. Foam extinguishers are suitable for fighting class A and B fires, i.e. those caused by solid materials (such as wood, paper, fabrics) or liquids (such as petrol, oil, paints). The foam forms an insulating covering over the fuel, preventing access to oxygen and lowering the temperature. Foam fire extinguishers are widely used in the naval sector, where fire risks are high. Gielle also offers a complete fire extinguisher maintenance service to guarantee the correct functioning of all fire-fighting devices. Characteristics of foam fire extinguishers Whatever the extinguishing agent used in foam extinguishers, they must comply with some common technical characteristics. First of all, the foam must have a specific gravity lower than that of the liquids on which it is applied, so as to float on them and isolate and separate them from the air. The foam must also be free from very toxic or corrosive substances, and must be homogeneous and heat resistant. Another important requirement of fire extinguishing foams is their elasticity. In fact, they must be able to cover and extend quickly on horizontal and vertical surfaces. Not sure which fire extinguisher to choose? Contact us now!
