6.1 Buildings and structures must ensure firefighting and rescue capabilities through the following solutions: structural, spatial planning, technical - construction, and organizational solutions.
6.2 Fire Truck Access Roads and Fire Truck Parking Areas
6.3 Overhead Access for Firefighting and Rescue
6.4 The design of turnarounds must comply with one of the following provisions:
6.5 For narrow roads only wide enough for 1 lane of vehicle travel, at least every 100 m, a widened section with a minimum length of 8 m and a minimum width of 7 m must be designed to allow fire trucks and other vehicles to easily pass each other.
6.6 For buildings of 2 floors or more with flat roofs or roofs with a slope of less than 25% and a height greater than or equal to 10 m measured to the eaves or the top edge of the outer wall (parapet wall), there must be direct roof access from stairwells or through the attic floor, or via a type 3 staircase, or via an external firefighting staircase.
6.7 In the attic floors of buildings, except for group F1.4 buildings, there must be roof access via fixed stairs and doorways, hatches, or windows with dimensions not less than 0.6 m x 0.8 m.
6.8 In technical floors, including technical basements and technical attics, the clear height of the passage must not be less than 1.8 m; in attic floors along the entire building - not less than 1.6 m. The width of these passages must not be less than 1.2 m. In separate sections with a length not exceeding 2 m, it is allowed to reduce the height of the passage to 1.2 m, and the minimum width is 0.9 m.
6.9 In buildings with an attic floor, there must be hatches in the enclosing structures of the attic floor cavities.
6.10 At points of elevation difference of the roof greater than 1.0 m (including elevation difference for lifting light and ventilation openings), firefighting stairs must be provided.
6.11 When arranging roof access using external firefighting stairs according to the requirements of 6.6, type P1 firefighting stairs must be used for heights up to 20 m and at roof elevation differences from 1.0 m to 20 m. Type P2 firefighting stairs must be used for heights greater than 20 m and at elevation differences above 20 m.
6.12 Between stair flights and between the handrails of stair flights, there must be gaps with a clear width in plan of not less than 100 mm.
6.13 Each fire compartment of buildings with a fire resistance height greater than 28 m (greater than 50 m for group F1.3 buildings), or buildings with a depth of the lowest basement floor (measured to the elevation of the escape exit to the outside) greater than 9 m, must have at least one firefighting elevator.
6.14 In buildings with a roof slope of up to 12%, a height to the eaves or the top edge of the outer wall (parapet wall) greater than 10 m, as well as in buildings with a roof slope greater than 12% and a height to the eaves greater than 7 m, there must be railings and handrails on the roof in accordance with current standards. Such railings and handrails must also be arranged for flat roofs, balconies, loggias, external corridors, open external staircases, stair flights, and landings, regardless of the fire resistance height of the building.
6.15 The firefighting water supply systems for buildings must be ensured to be accessible and usable by firefighting forces and equipment at all times.
6.16 The firefighting water supply as well as the equipment and arrangement of other specialized firefighting equipment for buildings and structures must comply with the basic provisions in Part 5 of this regulation and relevant technical standards.
6.17 Fire Control Room
6.18 All basement floors in buildings with 2 to 3 basement floors must be equipped with a two-way emergency communication system from the fire control room to the following areas:

APPENDIX D (regulation) SMOKE PROTECTION
D.1 General requirements
D.2 Smoke exhaust in case of fire must be implemented from the following areas:
D.3 The requirements in D.2 do not need to be applied to:
D.4 The smoke exhaust rate must be determined by calculation in the following cases:
D.5 The design of the smoke exhaust system for protecting corridors must be separate from the smoke exhaust system for protecting rooms.
D.7 When extracting smoke directly from rooms with an area exceeding 3,000 m2, the room must be divided (by enclosure solutions (using smoke barriers) or assumed solutions) into smoke zones (smoke reservoirs) with an area not exceeding 3,000 m2 and the possibility of a fire occurring in one of these zones must be considered. Each smoke inlet can only be considered to serve an area not exceeding 1,000 m2.
D.8 For direct smoke exhaust from rooms and corridors of single-story buildings, a forced smoke exhaust system or a natural smoke exhaust system through smoke shafts (ducts) with smoke dampers, through smoke hatches, or through open skylights that do not face the wind can be applied.
