In addition to complying with standards, fire doors must be functional according to the building structure and intended use. The standards have determined the criteria for stair width and tread spacing. The capacity of the stairs can be increased by taking into account the M2 of the building or floors and the density of people residing there. Things to consider are the age of the building, its intended use, the number of people on the floors and in the building, and the height of the building.


Fire escapes can be manufactured from the exterior of the building as well as from the inside of the building during project design. There should be emergency lighting and guidance systems to provide adequate guidance and illumination for escape on the stairs inside the building, and there should be fire-resistant fire doors with panic bars at the entrances and exits. Exterior stairs should be protected in the form of a cage to ensure escape safety.


Materials or items that may prevent escape or pose a risk of fire should never be placed on fire escape stairs and exits.

According to the fire escape regulations, all buildings with more than 4 floors must have a fire escape.

The relevant regulation articles are as follows.

* In residential buildings where the building height is less than 21.50 meters, the main exit is sufficient.

*In places where the building height is more than 21.50 meters and less than 30.50 meters, it is mandatory to arrange two stairs for the building.

*In places where the building height is more than 30.50 meters and less than 51.50 meters, it is necessary to build 2 escape stairs.

* In places where the building height is more than 51.50 meters, it is mandatory to build at least 2 protected escape stairs.
