The company "Leading Technology" offers the creation and maintenance of fire extinguishing systems.
Fire suppression systems are designed to prevent, control development, fire fighting and fire protection of persons and property. One of the most reliable means for solving these problems are automatic fire extinguishing system, which, unlike the manual fire fighting systems and systems managed by the operator, driven by automatic fire and provide rapid quenching of the fire unattended.
1. Systems of water and water and foam fire extinguishing
The most widely used now have automatic water extinguishing system, which are in a price range between systems and gas fire extinguishing systems, fire extinguishing powder. They are used on large areas for the protection of commercial and mixed-use centers, office buildings, sports complexes, hotels, businesses, garages and car parks, banks, energy facilities, military facilities and special-purpose warehouses, homes and cottages. Water is the most widely used means of extinguishing fires involving burning fires and various substances. The advantage of water is its cheapness and availability, relatively high specific heat, high latent heat of evaporation, chemical inertness to most substances and materials. Water is an effective cooling agent, is widely used for fire protection of objects neighboring with the burning. Automatic installation of fire extinguishing depending on the type of sprinklers are divided into the following types:
- Sprinkler - installations that use sprinklers
- Deluge - installations that use Spray drying
Automatic installation of water (sprinkler) fire-fighting, depending on the air temperature in the protected area (volume) divided into the following most commonly used types: Vodozapolnennye- used in rooms with minimum air temperature of 5 ° C and above. In these systems (plants) all the pipes are filled with water or an aqueous solution. Such systems are used on most objects.
Air - used in unheated buildings (eg warehouses, hangars, parking lots) with a minimum temperature below 5 ° C.
2. The system of powder fire extinguishing
Automatic installation of fire extinguishing powder designed for automatic fire detection, send the message about the fire staff on duty, automatic localization and fire extinguishing.
The principle of operation - flow into the combustion zone of fine powder composition. Extinguishing Methods: volume, the local area and local by volume.
Automatic installation of fire extinguishing powder divided into:
- Automatic installation of powder fire - fire detection is performed by a signal from an automatic fire alarm, followed by the arrival of the signal to start the system.
- Powder fire extinguishing installation with manual reset (local, remote) - giving the signal to start the automatic installation of fire extinguishing powder is carried out manually from the room fire post, fire stations, a protected area.
- Standalone installation - fire detection and issuing powder composition performed independently of external power supplies and controls.
Automatic installation of powder fire are the cheapest in the application systems. However, the powder is sprayed in the room, being chemically active, leads to corrosion of the metal and degradation of various types of plastic, rubber, paper and other materials. Very harmful ingress of powder on the skin or respiratory tract, this circumstance, in turn, imposes a requirement to evacuate people from the area to extinguish response (switching) system. This imposes restrictions on the use of these facilities and systems places high demands on reliability and protection against false alarms. The advantage of the system is the ease of installation, since they are autonomous. Their use is recommended, for example, in unserved or masloobsluzhivaemyh premises, where is the power equipment (substations, transformers, etc.). They can also be used in small offices. cottages, garages, warehouses.
3. The gas fire suppression system
There are a number of objects that can not be or is not economically feasible to put out the "traditional" methods and means. For example, these include: power plant, server rooms or data centers, stacks, museums, galleries of different purposes, etc.
Among the methods of fire fighting one of the most modern and effective is the use of automatic fire extinguishing systems (AUPT or automatic fire), allowing a direct impact on the fire in its origin, and thus avoid the spread of flame and a correspondingly large fire damage. As an extinguishing agent such systems utilize carbon dioxide, inert gases and various fluorochemical compositions hydrocarbons. Installation of automatic fire extinguishing it possible to localize and then put out the fire in the early stages of various fires. A method for automatically extinguishing when creating extinguishing concentration throughout the volume of the space protects called bulk. The most effective and bringing less damage in the liquidation of fire is a gas fire suppression system. Gas extinguishing agents are the volumetric fighting and divided into inert diluents and flame retardants. As the inert gaseous diluent is carbon dioxide, nitrogen, argon, water vapor. Burning stopped when most substances reducing the oxygen content in the atmosphere of the protected volume to about 12-15%.
The most widespread use of these diluents is gaseous carbon dioxide. Feature diogsida carbon is its ability to form a throttling flakes "snow". On the surface quenching "snow", it was diluted with carbon dioxide action is complemented by cooling the fire.
Among the most effective means of extinguishing gas have halogen carbohydrates, especially halons. Application of certain types of halon extinguishing allows a volume shall not be construed to provide fast and efficient fire suppression, but also to prevent the creation of an explosive atmosphere. Halocarbon suitable for quenching metal Many organometallic compounds, certain metal hydrides and when no oxidant is oxygen and the other substances
4. The aerosol fire extinguishing systems
Aerosol fire extinguishing systems - systems used to extinguish the fine particulate matter.
Disadvantages such as fire extinguishing systems represent a largely risk to human health (when triggered fire extinguishing system visibility in the room becomes almost zero, except aerosols can be inhaled or eyes). The simplest and most common devices of aerosol fire extinguishing systems are extinguishing aerosol generators (hereinafter GOA).
The operating principle of a fire extinguishing system, like Goa, is the emission of a mixture of inert gases and particulate matter formed during the combustion of solid substances on fire. These substances not only deny access of oxygen to ignite, but the oxidation reaction is slow. Fire-extinguishing system may operate as GOA spontaneously when the temperature rises, and with the help of various devices that react to smoke, heat and light, etc.
The service life of Goa are limited to 10 years, after which it must be removed and replaced with a new one.
The main advantage of fire-extinguishing system Goa - a low temperature spray.
The advantages of such a fire extinguishing system are primarily economic, technical and operational matters, such as ease of installation and installation versatility, high carcass ability, efficiency, use at low temperatures and the ability to put out material under stress.
Aerosol has no harmful effects on the human body and clothing, as well as the corrosive effects on the majority of structural and electrical insulating materials. Such systems can be used to extinguish fires of electrical equipment and other energy facilities, to protect vehicles, oil facilities, motor compartments of ships, and so on. N. The disadvantages of these systems are increasing the temperature and pressure of the gaseous medium in the protected area, a sharp decrease in visibility.
