4. Construction of fire protection system – fire fighting by foam foam:
Fire extinguishers, piping systems, fire valves, fire alarm systems. This system is mainly used for fire fighting of gas stations
Foam fire extinguishing systems are now used quite a lot because it reduces the amount of water needed, reduces the number of fire extinguishing agents in the fire, reduces environmental pollution, and for high expansion foam, most as if there was no damage to the goods, and within a short time the whole warehouse was back to normal.
Foam extinguishing systems are used in areas with a high risk of fire and explosion, carefully selected, requiring proper foam concentrates, foam mixing systems, foam spraying equipment, and Effective coordination between these components in a fire-fighting system.
Fire extinguishing system foam, when activated, will spray a type of foam covering the surface of gasoline, separating the flammable liquid from the air and the 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.
Fire-fighting principle:
Depending on the type of foam, you can fight fire in several ways:
Either use a foam to cover the surface of the combustible with a thick layer of foam, extinguish the flame and isolate the fuel from continued exposure to air, or cool the fuel with the amount of water contained in the foam. or cover to prevent liquid (fuel) from evaporating and mixing into the air.
