In modern civil engineering is most often used hinged fire doors and gates. Lifting and downcomer designs are used in warehouses, dryers and other similar objects such as doors and gates are suitable for fire protection of technological gaps.
Design for drop-lifting and sliding type is not mounted on the escape routes. To install on escape routes need Swing doors with seals that do not interfere openings without a key from either side. The door should be fitted with self closing.
To protect the premises of explosive used special intrinsically safe door, the canvas on the edges of which is protected by plates of nonferrous metal. Doors with fire-resistance rating EI 60 and partitions with fire-resistance rating EI 45 belong to the first type of fire barriers, doors with fire-resistance rating of EI 30 and partitions c fire-resistance rating EI 15 - the second type doors with fire-resistance rating EI 15 - the third type.
Fire partitions of the first type have the same fire resistance as the fire wall of the second type, but from the standpoint of fire safety partition can not replace the wall. This is explained by the fact that using the partitioning you can limit the spread of fire within only one floor, whereas the wall protects several floors.
In accordance with current fire regulations walls shall be designed and installed in the wall of elevator shafts and elevator machine rooms, as well as in mines and channels for communication laying, because of fire, these areas are the most likely ways the spread of smoke and other combustion products.
Gas-tight building envelope is used to highlight areas in which the processes carried out related to the release of dust, gas and vapor-air explosive mixtures. Gas-tight fire walls can also be separated storage and other facilities that have no fire load.
