The “foam” in foam fire suppression systems is an extinguishing agent that cools and separates the ignition source from the surface to extinguish flammable or combustible liquid. Fire and fumes are both suppressed and suffocated by the foam. It can also keep a fire from starting again. This foaming agent is composed of tiny air-filled bubbles with a lower density than water. Water, foam concentration, and air combine to make foam.
In order to minimize contact with oxygen and lessen the fire’s capacity to burn, foam suppression devices are utilized to cool the flames and cover the fuel that the fire is eating. When the foam is dispersed, it covers or smothers the fuel’s surface. In order to avoid re-ignition by flammable vapors, the fuel and the foam region surrounding it are cooled by the foam’s water content.
Like a wet sprinkler system, foam suppression systems use pipes to transport stored water to nozzles where it is released. The inclusion of the foaming ingredient marks the primary distinction between foam systems and other conventional wet sprinkler systems. The water and foaming agent are stored separately and are combined in the pipe system before being discharged. A nozzle is located at the piping’s end. The foaming agent is pumped or added to the water just before discharge. The foaming ingredient expands when it comes in contact with water, producing a thick layer of foam that may fill large spaces.
There are various foam types to choose from. Allow the fire suppression system specialists at Fire Prevention and Consultancy Service to assist you in selecting the right option for your company. It’s always a good idea to make a solid preparation in advance since you never know when an unexpected event may occur.
