Foam concentrates are designed to meet a wide range of fire-fighting challenges. Aqueous film-forming foams (AFFFs) are suitable for ground, air and creating firebreaks on equipment to stop migration of fire. Foams are some of the most environmentally friendly products in their class in the world. A major advantage of foams is that they form a film on oils and diesels. This means they can follow the path of oil leaks that may start a fire away from a nominated risk area. Added to this the foam has a cooling effect and can dramatically reduce the heat in turbos and other high heat sources.
