Foam Fire Extinguishers (Class A & B Fires)

Foam Fire Extinguishers (Class A & B Fires) are designed to extinguish fires involving ordinary combustible materials such as wood, paper, and textiles, as well as flammable liquids like petrol, diesel, and oil. They work by cooling the burning material and forming a foam blanket over the fuel surface, helping to suppress flammable vapours and prevent the fire from reigniting. Foam fire extinguishers are commonly used in offices, warehouses, factories, petrol stations, workshops, and commercial buildings. They provide effective fire protection for areas where both solid combustible materials and flammable liquids are present. However, standard foam extinguishers should not be used on live electrical equipment or cooking oil and fat fires unless specifically rated for those applications.
