Foam extinguishing systemsare extinguishing systems whose content is foam liquids and waiting for intervention under a certain pressure.
Foam extinguishing systems that show a very effective function in fires caused by flammable liquids and types of fires caused by fuels, sprinkler can be multiplexed using foam extinguishing systems.
Therefore, foam extinguishing systems are prepared as special automatic systems to protect larger areas from fire.
Foam extinguishing systems are frequently used in helicopter and airplane hangars with high investment value in order to protect against fires that may be caused by all materials and fuels that may ignite.
Foam extinguishing systems, which have a widespread use worldwide, quickly interact with flames.
In addition, the extinguishing capability of these systems is also very high.
Foam extinguishing systems also fulfill the function of protecting the health of the people who intervene in the fire by ensuring that the gases released by the material ignited during the fire are also retained.
Foam extinguishing systems also fulfill a complete extinguishing task, as they have the ability to hold not only on materials with a horizontal surface, but also on materials that ignite vertically.
Therefore, foam extinguishing systems are considered as one of the most capable extinguishing systems and are frequently preferred.
What are the Features of Foam Extinguishing Systems?
The main features of foam extinguishing systems with an effective extinguishing effect are as follows:
- Foam extinguishing systems prevent oxygen and fuel vapor from coming into contact.
- Foam extinguishing systems, which prevent evaporation on the fuel surface, also separate the flame and the fuel surface from each other.
- Foam extinguishing systems help to cool the metal surfaces on or around the fuel surface.
Foam extinguishing systems, which have highly effective tasks, are used to extinguish various fires such as crude oil fires, gasoline fires, gel fuel fires, gasoline fires, fuel oil fires, naphtha fires, fires occurring in alcohols, fires occurring in ketones, fires occurring in ethers and fires occurring in esters.
What are the Types of Foam Extinguishing Systems According to Foam Chemical Properties?
Foam extinguishing systemsfoam is divided into two types according to its chemical properties.
One of these types is protein-based systems, while the other is synthetic-based systems.
Protein-based foam extinguishing systems include protein-based (P) foam fluids, fluoroprotein (FP) foam fluids, film-forming (FFFP) foam fluids and alcohol-resistant film-forming (AR-FFFP) protein-based foam fluids.
On the other hand, synthetic-based foam extinguishing systems include fluent film-forming (AFFF) foam fluids and alcohol-resistant fluent film-forming (AR-AFFF) fluids.
Where are Foam Extinguishing Systems Used?
Foam extinguishing systems are highly effective on the so-called hydrocarbon fires and polar solvents.
Foam extinguishing systems have a wide range of applications.
These systems are generally used in aircraft and helicopter hangars, warehouses, fuel loading or unloading stations, paint factories, chemical production or storage facilities, flammable and flammable liquids storage areas, flammable and flammable liquids filling areas, shipyards, piers, oil refineries, marinas and similar areas.
Foam extinguishing systems affect the flammable surface in a short time and prevent possible large fires due to their instant intervention and rapid control.
Foam extinguishing systems are widely used especially in oil refineries, aircraft and helicopter hangars, shipyards, docks, fuel filling and storage facilities.
In addition, foam extinguishing systems are a system that allows the foam, which has a lower density with the combination of pressurized water and foam and can adhere to both horizontal and vertical surfaces, to cover the flammable area.
At the same time, thanks to these systems, explosive gases are prevented from escaping.
Working Principle of Foam Extinguishing Systems
Foam extinguishing systems The working principle is an issue that should be taken into consideration from the project design phase to the fire intervention and post-fire cleaning phase.
Foam fire extinguishing agents stored in pressurized cylinders during the production phase should be kept ready in the appropriate principle so that they can work pressurized at the time of intervention with post-project assembly.
Periodic maintenance and repairs of these systems should be carried out regularly.
Foam extinguishing systems should work in integration with detection systems.
In addition, these systems also depend on the health of the systems that recognize the fire and the systems that transmit it to the operating center.
For this reason, both regular maintenance and repairs of foam extinguishing systems should be carried out periodically.
Foam extinguishing systems, as a working principle, have qualities that start the system when it is understood that the fire has started, provide intervention for every point and support the fire extinguishing personnel team in every aspect.
Foam extinguishing systems, which require a completely specialized engineering work, are subjected to a professional process.
Foam Extinguishing System Design
Foam extinguishing system designs are made completely in the light of scientific data and hydraulic calculations in accordance with the provisions of the relevant law.
In the design of foam extinguishing systems, the rate at which the chemical contents produced according to demand should be used is determined with a completely professional approach.
It is very important that the chemicals that work during a fire are ready in the fire extinguishing system.
Unlike chemicals in fire extinguishers used in manual interventions, extinguishers of very different densities are used in automatic systems.
Foam extinguishing systemAnother important consideration in i design is the size of the area and the substances to be protected or extinguished.
How Do Foam Fire Extinguishing Systems Work?
Foam fire extinguishing systems work by cutting the contact of air and fuel vapor, separating the fuel surface and the flame, preventing evaporation on the surface or cooling the metal around the fuel surface.
What Are The Types Of Fires Where Foam Is Effective?
Among the types of fires where foam is effective in foam fire extinguishing systems are hydrocarbon fires and polar solvent fires.
What Types of Foam Are There According to the Content of the Foam?
Foam fire extinguishing systems are divided into two types as protein-based and synthetic-based depending on the foam content.
How to Design a Foam Fire Extinguishing System?
Foam fire extinguishing system designs are made together with hydraulic calculations in the light of scientific data and in accordance with the provisions of the relevant law.
What Equipment is Required for Foam Extinguishing Systems?
Foam extinguishing systems require equipment such as various nozzles, foam chamber-foam chamber, foam maker-foam maker, foam tank and foam monitor.
