Aqueous Film Forming Foam is one of the most commonly used mediums by the fire brigade for dealing with fuel fires. As the name suggests, in coming into contact with a burning liquid the agent forms a blanket over the burning substance – therefore extinguishing the fire by removing its oxygen source, while the liquid cools the fire. This helps to prevent flashbacks through removing two elements of the fire triangle and inhibiting the automatic production of free radicals.
It is an effective and versatile method of fire fighting, combining the effects of the water, water spray and foam into one unit. It is often recommended for office use alongside a CO2 extinguisher – this means that all likely fire risks are safely covered.
