What is the Importance of Fire Extinguishing Systems?
Fire extinguishing systems are systems that undertake a vital function in case of fire, which is always a threat factor in daily life and requires to be always alert due to its unpredictability.
Detailed exploration, correct engineering, appropriate equipment and routine control at the required intervals in fire extinguishing systems are a necessity to prevent material and moral losses caused by fire.
What are Automatic Fire Extinguishing Systems?
An automatic fire extinguishing system basically extinguishes flames or smoke
It refers to systems that detect and start to extinguish quickly.
There are watery, foamy and gaseous types according to the suitability of its use in the space.
How Should We Choose Automatic Fire Extinguishing Systems?
Automatic fire extinguishing systems require no intervention.
They are the systems that realize fire fighting in the fastest way without staying.
Like all fire extinguishing systems, it is used to protect volumes and equipment in buildings and spaces.
In addition, it is preferred to work in integration with other detection and warning systems.
It can be installed in any region or the whole area decided by making feasibility.
Automatic fire extinguishing systems are available in water, foam and gas types.
Each place needs to design a fire safety system that will be unique to it.
For example, fire safety of an archive is also possible with water extinguishing, in a possible fire, fire will be prevented with a water extinguishing system, but the documents in the archive will also become unusable.
Or a fire can be extinguished with CO² in an office environment, but human life will be endangered by the harmful gas.
Likewise, in areas such as tank areas, airplane and helicopter hangars where some flammable and flammable liquids that cannot be extinguished with water, foam extinguishing systems should be preferred rather than water extinguishing systems.
The reason for this is that water extinguishing systems are insufficient for extinguishing in these areas and do not meet the needs.
As always, the correct engineering and exploration work will be decisive in the installation of the most suitable automatic fire extinguishing system for the location in question.
How Does an Automatic Fire Extinguishing System Work?
Automatic fire extinguishers available in watery, foamy, gaseous varieties
The working principle of extinguishing systems is different from each other as well as the area of use.
The water extinguishing system works by bursting the sprinklers in that area due to the heat generated by the fire in any area and pressing the water absorbed from the tank.
Foam fire extinguishing systems, which are preferred in areas containing flammable and flammable liquids and carrying special risks, 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.
Confined spaces that are hazardous or dangerous to extinguish with foam,
Gas extinguishing systems are preferred in cases where there are fire risks that can be damaged by water or that cannot be extinguished with water, but can spread to a wider area with water.
Gas extinguishing systems extinguish the fire by lowering the temperature of the environment and reducing the amount of oxygen below the combustion limit.
Where are Automatic Fire Extinguishing Systems Used?
The decision of where automatic fire extinguishing systems will be used is determined by engineering studies.
Automatic fire extinguishing systems are especially preferred in museums with historical artifacts, archives with valuable documents, security rooms and telephone exchanges; factories with valuable materials or other businesses with larger areas and oil refineries, aircraft and helicopter hangars, shipyards, shipyards, piers, fuel filling and storage facilities.
Clean gases are defined as electrically non-conductive gases that do not have a negative impact on human health.
Clean gas extinguishing systems lower the temperature of the environment, reduce the amount of oxygen below the combustion limit and extinguish the fire.
Clean gases provide highly effective results when used with early warning fire detection systems.
What are Gas Extinguishing Systems?
Gas extinguishing systemsis constantly updated in the light of new generation technologies, allowing different arrangements day by day.
In a fire that occurs in an area protected by these systems, electronic equipment that is not directly exposed to fire is not damaged.
For this reason, solutions offered by these systems are used in rooms with important electronic equipment.
According to the working principle of the system, after the gas is evacuated and the fire is extinguished, the gas in the environment is cleaned with the ventilation of the area and there is no waste material around.
Since the electronic equipment is not damaged, there is no disruption in the use of the room and equipment.
What are Gas Fire Extinguishing Systems?
Gas fire extinguishing system types are as follows:
- FM 200 Gas Fire Extinguishing System
- Novec1230 Gas Fire Extinguishing System
- C02 (Carbon Dioxide) Gas Fire Extinguishing System
- Inergen Gas Extinguishing System
How Do Clean Gas Extinguishing Systems Work?
Automatic gas extinguishing systems Thanks to the clean gas systems among them, fires are extinguished much more quickly and practically and possible disasters are intervened early.
The systems used to maximize and overcome the fire extinguishing process must be installed individually in the area to be protected.
In addition to the extinguishing system, an extinguishing control panel should be placed in each area.
Thus, the control of that area becomes easy.
Detection detectors are placed accurately with the cross zone method and automatically intervene in the fire.
Double detector gas fire extinguishing systems When the fire is first detected, the siren sounds intermittently, and after two detectors detect the fire, the siren starts to sound continuously.
Exactly 30 seconds after the siren, the gases are discharged onto the flames and the risk of fire is eliminated.
If necessary, fire brigades can come and carry out cooling works.
At the last stage, experts determine whether the materials in the environment are damaged.
What are the Characteristics of a Clean Gas Extinguishing System?
Gas fire extinguishing systems have various features.
These can be listed as follows:
- The fire extinguishing capability of such gases is quite high.
- It does not leave any waste in the environment after discharge.
- Clean gases have no electrical conductivity.
- The cost of refilling gases is affordable.
Which Gases are Used in Extinguishing Systems?
The following gases are used for extinguishing systems:
Chemical Gases
- Novec 1230
- FM200
Inert Gases
- Inergen ( IG-541)
- Argon (IG-01)
- Argonite (IG-55)
- Nitrogen (IG-100)
In addition to these gases, a new generation product aerosol gas fire extinguisher is also an effective agent.
Aerosol, a category of dry powder, is placed in portable extinguishers.
This system, consisting of solid or liquid particles suspended in the air, intervenes in the chain reaction by removing free radicals through chemical processes and extinguishes the fire.
Solid and liquid flammable materials, low-voltage power plants and environments with electronic devices are suitable areas for this device.
Where are Gas Extinguishing Systems Used?
Clean gas extinguishing systems are used in rooms and areas where sensitive materials and equipment are located.
Especially museums with historical artifacts, archives with valuable documents, security rooms and telephone switchboards are the main areas where these systems are used.
What are the Usage Areas of Clean Gas Fire Extinguishing Systems?
Clean gas fire extinguishing systems can be used in the following areas:
- Data processing centers
- System and server rooms
- Exhibition halls
- Museums
- UPS rooms
- Electricity distribution panels
- Archive rooms
- Chemistry laboratories
- Flammable liquid storage areas
What is System Room Fire Extinguishing System?
Halon gas, which was used in system room fire extinguishing systems in previous years, created equipment and cleaning problems in the areas despite its effective performance in fire extinguishing activities.
For this reason, FM200 gas, which is a cleaner extinguishing element, is preferred for such extinguishing interventions in recent years.
This gas does not leave any residue in fire areas and does not require cleaning after the process.
FM200, one of the most non-toxic gas types, is easily preferred in fully automatic extinguishing processes due to its safe usage features. The gas, which does not harm the ozone layer, is one of the most suitable fire fighting agents. Offering superior fire extinguishing performance where electronic equipment is located, the gas type is highly capable of extinguishing flammable and flammable liquids.
What is Server Room Fire Extinguishing System?
FM200 gas is preferred in server room fire extinguishing processes, just like in system rooms.
This colorless and odorless gas is ideal for use in server rooms where important equipment is located, as it does not leave physical damage on the surface to which it is applied.
In the system where the liquid gas is applied to the surface by spraying, a layer is formed on the surface.
FM200, which does not contain chemical properties like its biggest competitor halon gas, is a completely physical extinguishing agent.
Thanks to this gas, which can intervene in the fire in a short time, heavy losses that may occur during the fire are prevented.
FM200 gas extinguishing systems are installed in the environment after a detailed risk analysis by experts. In this system, the cylinders are filled with 25 bar / 42 bar / 50 bar pressure, and when the gas protected in liquid form in the tube is sprayed, it reaches the surface as foam. Thanks to the system that covers the burning surface like a blanket, the fire is extinguished by suffocating.
