EFFPL uses Fire Foam Supression System including various foams based on their expansion to cool fire and coat fuel. Along with this EFFPL uses Fire Foam Supression System to prevent the fire getting in contact woith the oxygen which can result in supression and combustion.

Fire Foam Suppression Systems is a fire control system which works on mitigation and controlling the fire with the help of foam. This foam concoction consists of air, water and foam concentrates. This mixture forms a homogeneous foam blanket which works on a extensive method of putting the fire out by cooling the fire down and controlling the vapors.
Types of Foams Used A Fire Foam Suppression Systems has two different types of foams to destroy the fire, Class A foams, and Class B foams. Class A foams are commonly used by fire departments to destroy residential and small commercial fires. Class B foams are used in places which have flammable liquids which may not be readily destroy using traditional fire control systems. Class B foam is also a good option to destroy fires with flammable gases. Fire Foam Suppression Systems works in different ways depending on the type of the fire. Fire are divided into classes: A for ordinary combustibles, B for flammable liquids, C for energized materials, and D for combustible metals. Foam is commonly used on the first two classes, A and B and they use different types of foam and equipment.
Class A foam Class A foam works by absorption into the burning material, breaking down the surface tension and allowing water to perceiving it better, thereby cooling it and inhibiting its access to oxygen. Additionally, Class A foam "sticks" to fuel which permit the properties of water to be applied to them longer. Class A foam systems involve a water supply, a pump, hose, foam concentrate, an eductor or injector and a nozzle. The foam is mingled with the water in the hose at the injector at a percentage of generally .1-1%
Class B foam Class B foam operate by forming a vapor barrier over the flammable liquid stop the vapors from the fuel to ignite. There are many types of Class B foam for the different types of fuels and there are different types of application depending on the situation. Class B foam systems operate slightly different than Class A systems. They are commonly comprised of a pump, foam concentrate, hose, a water supply, an agitator, an injector and a nozzle. The biggest difference is that the Class B foam has to have bubbles to work. While frequent times you cannot tell when a suppression system has Class A foam, if you cannot tell Class B foam is coming from the nozzle, then something is wrong with the system. Class B foam is commonly applied at 3-6%.
