5. Construction Fire protection system – foam fire fighting:
Foam extinguishers, piping systems, fire valves, fire alarm systems. This system is mainly used for fire fighting for gas stations
Foam fire extinguishing system is now used quite a lot because it reduces the amount of water needed, reduces the amount of extinguishing agent when extinguishing a fire, reduces environmental pollution, for high expansion foam, most there was no damage to the goods, and in a short time the whole warehouse was back to normal.
Foam fire suppression systems are used in areas with a high risk of fire and explosion, carefully selected, requiring the appropriate provision of foam concentrates, foam mixing systems, foaming devices, and effective coordination between these parts in a fire fighting system.
When activated, the foam fire extinguishing system will spray a foam that covers the surface of gasoline, separating the flammable liquid from the air and fire, thereby extinguishing the fire.
The foam mixing system can be either “balanced pressure” or “inline”.
The foam nozzle can be a sprinkler, spray, nozzle, monitor, foam pourer, or high expantion foam generator, depending on the foam system used.
Principle of fire fighting:
Depending on the type of foam, fire can be extinguished in several ways:
Either use foam to cover the surface of the combustible with a thick layer of foam, extinguish the flame and isolate the fuel from further contact with the air, or cool the fuel by the amount of water contained in the foam. , or a cover that prevents the liquid (fuel) from evaporating and mixing with the air.
