How does the sprinkler foam system work?
A fire cabinet is not an automatic system. The dimensions of the cabinets must be at least 600X 700X 160 mm. A fire cabinet must contain a rubber and linen-based rubber hose with a pressure resistance of 10 kgf/cm2 and a fire tap. A nozzle that distributes water must be tightly attached to the end of the rubber and linen hose. The fire hose should be wound neatly on the reel inside the cabinet or folded neatly on the shelves. The important point inside the cabinet is that in case of any fire, after manually opening the tap inside the cabinet, the hose should be able to be deployed without tangling or any problems when running towards the fire. Hose lengths generally vary between 10 and 30 meters.
Foam concentrate is a mass obtained from the mixture of air, foam concentrate, and pressurized water, with a density lower than oil and water. It covers the burning object like a blanket, cutting off all contact with the air, adheres to all outer surfaces, prevents the escape of expanding gases, and can sustain all these for a long time.
What should be the distance between fire systems?
Fire cabinets are mandatory in all buildings with closed areas such as high-rise buildings, accommodation areas, bazaars, and assembly buildings with an area of 2000 m2 and above, and in workshops and manufacturing plants with an area larger than 1000 m2. The distance of fire cabinets can be up to 45 meters on floors if there is a fire department connection and sprinkler system protection. However, if such a setup does not exist, they must be placed at 30-meter intervals.
According to their chemical structures, they have protein-based, film-forming, and alcohol-resistant properties. There are many types of foam sprinkler systems for different spaces. In terms of working principle, it works like a water sprinkler system. However, additionally, foam-making agents are discharged from the sprinkler. The system is applied using a completely dry fire cabinet. It works with the help of foam makers.
