What are the benefits of fire doors and what are they like?
Every year, hundreds of fires occur in the Russian Federation (as well as in the former CIS countries and other countries), during which rooms and furniture are burned, computers and other property are damaged, and sometimes people are killed by burning or suffocating with carbon monoxide. To protect offices, schools, shopping malls, industrial enterprises from fire, people install sprinkler fire extinguishing systems around their perimeter, place fire extinguishers in some places of the building, and also install fire barriers-doors.
It is worth noting that any fire door does not prevent the appearance of fire and will not be able to extinguish it. It is only for a few minutes (fifteen, twenty, thirty, sixty) it is able to delay its spread. But even these fifteen minutes will be very valuable for people who will be able to evacuate from the building engulfed in flames so as not to die. Installation of fire doors is especially relevant and expedient in such premises as chemical laboratories, boiler rooms, paint shops. Although many people order the installation of a fire door in their own home, office, factory.
The design of the fire door includes a door frame, seals and accessories (lock, hinges, end bolts, anti-removable bolt). A cold-rolled sheet of metal is used for the manufacture of the door frame. Both domestic and foreign companies are engaged in the production of fire doors, and their products may differ in both fire resistance class and design – some doors with fire-fighting properties may partially consist of laminated glass.
Depending on the installation location, fire doors are divided into entrance, internal and technical, and depending on the design into single- and double-floor, blind and partially glazed. Fire doors may differ from each other also by their weight. If Russian manufacturers of these products include drywall and mineral fibers in its composition, then European firms fill their doors with polyurethane fire-resistant foam.
If a fire breaks out in a building where a fire door is installed, it will prevent its spread, and a seal that has foamed under the influence of high temperature will not let smoke and carbon monoxide through. But the fire brigade will still have to be called, having previously evacuated all people from the building. Such partitions are subject to state mandatory certification and testing in an accredited laboratory.
