FIRE BARRIERS
Fire barriers are products that can slow down and stop the process of spreading fire. They protect people and animals from deadly flames. Thanks to the barriers, financial losses in the event of a fire are significantly reduced. The presence of the device accelerates and facilitates the evacuation of staff or residents.
Where are barriers used and how do they function during a fire
Fire barriers are necessary in multi-storey residential complexes, production workshops and administrative buildings. They are installed at all facilities where there is a high probability of fire. It is strictly forbidden to organize the process of manufacturing or processing of flammable products without fire-fighting products. Partitions are ordered by companies that produce pyrotechnics, paint and varnish materials and fill gas cylinders. Using constructions:
-
isolate the premises from external escape ladders and underground passages;
-
separate corridors, the length of which exceeds 60 meters;
-
zoned production sites;
-
create a vestibule-gateways.
When a flame breaks out, barriers allow you to gain time. Structures become a reliable barrier in the way of fire. Heat-resistant barriers hold back the flames when a car with a fire brigade, water supply and a hose rushes to the rescue. Selected models are equipped with sprinklers and special inserts that instantly expand under the influence of extremely high temperatures to seal the room. A fire alarm can close the opening to locate the source of danger.
The main types of fire barriers
There are dozens of types of fire barriers of local and foreign production on the market. Stationary structures are created using concrete, porous blocks and a variety of non-combustible materials. To fill the openings , they are made:
-
doors;
-
screens;
-
valves;
-
gates;
-
curtains;
-
hatches.
The listed products differ in fire resistance limit, size and other less significant characteristics. In turn, the gates are divided into swing, folding, sectional and roll models. The choice of an obstacle depends on the specifics of a particular object.
MBA and FireTechnics fire gates and their advantages
The MBA company produces fire-fighting devices under the brand FireTechnics. During the manufacture of gates, the requirements of GOST R 53323-2009 are taken into account. The structures withstand contact with fire for 60-120 minutes. They are necessarily tested in a laboratory that issues a state-issued certificate. Fire gates consist of the following basic elements:
-
thermoactive seals;
-
hatches for stretching fire hoses;
-
electric motors or/and mechanical drive (cables, rods);
-
guide parts.
Selected structures are complemented by small gates that allow emergency evacuation.
Automatic MBA models are triggered after the fire alarm is turned on. Usually the built-in electromagnet holding the web is de-energized. After a few moments, the gate closes without human intervention. Roll and sectional models are driven by electric motors. When the mains voltage disappears, the control system switches to power from the backup battery.
The high demand for MBA fire gates is explained by such positive characteristics:
-
unlimited service life;
-
maintainability;
-
competitive price.
The protective device can be installed before entering the hangar, service station, museum, shopping center or inside any room.
Smoke-proof curtains from the manufacturer
If you are going to buy smoke-proof curtains, you should not contact intermediaries. Only the manufacturer is able to guarantee the high quality of its products. Manufacturers sell goods at the most affordable cost without store margins. After installing smoke-proof curtains, the security level of the facility is significantly increased. In the event of a fire, the curtains do not allow the combustion products to spread throughout the room. The curtains are lowered automatically by the gravity of the lower bar. The absence of smoke allows you to save material values without risk to health or life.
Installation of fire-resistant barriers
It is strictly forbidden to install obstacles with your own hands. In the absence of experience and skills, you are guaranteed to make gross mistakes during work. An improperly fixed barrier will not be able to protect against a deadly flame. Smoke will penetrate through barely noticeable cracks and complicate the evacuation process from the building.
If you need to install a barrier, contact professionals for help. Only registered organizations that are members of the SRO and have a license from the Ministry of Emergency Situations of the Russian Federation have the right to carry out complex work. During installation, the recommendations of the manufacturer of the structure and fire safety rules are taken into account.
The price of fire curtains and curtains
The cost of curtains depends on the size and characteristics of the material used. For one square meter of a two-layer canvas in the capital, they ask for at least 5,000 rubles. The Accordion system, which rises and creates a closed space after the sensors are triggered, will cost more. One square meter of this type of product costs more than 20,000 rubles. If you are afraid of vertical flame propagation, you will have to buy a floor or ceiling product. On the market you can find a horizontal curtain for 17-19 thousand rubles. The most affordable option is a fire–proof curtain made of a single-layer membrane. A square meter is sold in Moscow for only 3,700 rubles. Prices are constantly changing.
