Buildings, Fire Compartments, Spaces

3.32. Buildings and parts of buildings, separated with fire walls – fire compartments (hereinafter buildings) – are divided in terms of their fire resistance extent, structural and functional hazard classes. In terms of explosion and fire hazard – in accordance with RNTP 01.

Fire walls of the 1st and 2nd types are used to separate fire compartments.The fire-resistance rating of the building is determined by the fire-resistance of its building

structures and maximum fire spread over these structures.The functional fire hazard of the building and its parts (F) is determined by their designation

and specific features of processes accommodated in them.In buildings with the 2nd degree of fire-resistance for production and storage purposes it is

permissible to use columns with the ultimate fire-resistance of 0.75 hr.In the buildings with all fire-resistance degrees for separation of workplaces within the

spaces it is admissible to use partitions (glazed or with screens at a height of the blind part no more than 1.2 m, collapsible and extendable) with non-standardized fire-resistance ratings and flame spread limits.

3.33. Buildings and fire compartments are divided in terms of fire resistance degrees. The fire resistance degree of buildings is defined by the minimum fire-resistance of

building structures and minimum flame spread limits for these structures, according to table 2.

Page 9: SNiP RK 2.02!05!2002 (E) Fire Safety of Buildings and Structures

The approximate characteristics of buildings depending on their fire-resistance degree are adduced in Appendix 3.

The fire-resistance rating of bearing components in a building, which concurrently bring about the functions of enclosing structures, for example supporting walls, in the regulatory documents should meet additional requirements for integrity and heat insulating ability loss with due consideration for the functional fire hazard class of buildings and structures.

The bearing components of a building include structures which provide its general stability and geometric invariability during fire include: bearing walls, frames, columns, girth rails, arches, girders and beams of floors, junctions, stiffening diaphragms, etc.

The fire-resistance ratings of the filling in openings (doors, gates, windows and hatches, as well as lights, including rooflights, and other translucent parts of floor coverings) area not standardized, except for intentionally specified cases and filling of openings in fire-prevention barriers.

In case, when the minimum fire-resistance rating of the structure is 0.25 hr, it is permissible to use unprotected steel structures irrespective of their actual fire-resistance rating.

from the spaces, where they can be exposed to fire hazardous factors. Evacuation can also be considered as an adjective movement of people, pertaining to low-mobile population groups, which is brought about by servicing personnel. Evacuation is carried out via evacuation ways through evacuation exits.

4.3. Rescue feature a forced movement of people outward when they are exposed to fire hazardous factors or emergence of direct threat of this exposure. Rescue operations are brought about independently, with the help of fire-fighting teams or specially trained personnel, including with the use of rescue equipment, via evacuation and emergency exits.

4.4. People on the evacuation ways are protected by a system of space planning, functional, engineering and organization measures.

METHOD FOR CALCULATING THE CONDITIONS OF PEOPLE’S SAFETY ASSURANCE *

1. General Provisions

1.1. The indication of safety level for people in case of fire (QВ) is the probability of exposure to hazardous fire factors (HFF) per person a year. Safety of people is considered assured, it the following condition is fulfilled:

(1)

1.2. QВ is determined for people, staying in any (each) space of a building, proceeding from the assumption that the safety level for all people in one room is identical.

QВ value for one space is determined, given one most favorable calculated situation. If determination of the most unfavorable situation does not seem possible, it is necessary to conduct calculations for two or more situations. In this case the greatest of the obtained QВ values is inserted into inequality (1).

1.3. Calculated situations depend on the place of fire emergence (relative to the space, for which QВ is calculated) and ways of HFF spread.

The following calculated situations are possible:

Spaces, for which QВ is determined Characteristic of calculated situationsHall spaces (stores, restaurants, movie theatres, casinos etc.)

a) Fire starts directly in the hall or spaces, associated with the hall via open aperture;b) Fire starts outside the hall, and HFF block one of the exits from the hall, spreading in the corridor, hall, lobby.

Business, residential and other premises leading to a common corridor (hall, lobby)Atriums

Fire starts in a space close to staircase, smoke spreads to the corridor (hall, lobby) and HFF spreads along the stairs (except for smoke-free stairs of the 1st type)Fire starts in the lower part of the atrium, HFF spreads over the entire atrium.

Page 40: SNiP RK 2.02!05!2002 (E) Fire Safety of Buildings and Structures

* Calculation method is based on the procedure of GOST 12.1.004-85.

2. Basic Calculation Dependencies

2.1. QВ is calculated by the formula

(2)

where РЭ – probability of successful evacuation of people; Ri – probability of effective actuation of FPS i-th element; КB – probability of fire emegence and development.

2.2. FPS elements, taken into account in equation (2), include:automatic fire-fighting installations (AFFI);components of smoke protection of a building (SPB);fire alarm and evacuation management system (FAEMS);Automatic fire alarm is regarded as an integral part of SPB and (or) FAEMS.It is admissible to take into account the availability and efficiency of other systems, the

functioning of which enables the fire to be eliminated at early stages, provides safe movement of people on evacuation ways, enables them to be evacuated prior to blocking by fire.

2.3. Ri is determined from the table, depending on the type of equipment and nature of servicing the system.

2.4. The probability of successful evacuation (Re) is determined by the formula

(3)

where РЭ – probability of evacuation via evacuation ways; РДВ – probability via other exits from a space, not taken into account when РЭП was

calculated or rescue with the help of personal equipment.2.5. REP is determined depending on the calculated situations, indicated below.a) Fire started in a space ( including a reading hall), for which QВ is calculated. If the parameters of evacuation ways and exits from a space meet the requirement of

standards, then the probability of РЭП is determined by the formula

Page 41: SNiP RK 2.02!05!2002 (E) Fire Safety of Buildings and Structures

(4)

where - time lag of FAEMS (time from discovering fire to relaying about the fire to people and the necessity of evacuating, min ( 2.7). For spaces with capacity of less than 100 persons, it is necessary to assume <0,5min. For spaces with the capacity 100 persons, non-equipped with reporting facilities over the radio, accept = 1.5 min. FAEMS time lag is determined in compliance with 2.7.

If in planning of evacuation ways there are decisions, not specified by the current standards, it is necessary to determine the evacuation time tP and the time of blocking the evacuation ways by fire by way of calculation, and check the condition of evacuation from the interrelationship

(5)

If the conditions (5) are fulfilled it is necessary to apply formula (4). If conditions (5) are not fulfilled, safe evacuation of people from the hall is not regarded as ensured; it is necessary to change the planning of evacuation ways or implement other decisions.

The evacuation time tP and the time of blocking evacuation ways shall be calculated by the methods, developed by leading organizations in the field of fire safety measures.

b) Fire starts outside the space, for which QВ probability is calculated.If the planning, parameters of evacuation ways and exits from the space, corridor (hall,

lobby), staircases meet the requirements of the current standards, the probability of evacuation is determined by formulae:

for people staying on the floor, where fire started

(6)

for people staying higher than the floor, where the fire started

(7)

With planning and structural decisions of evacuation ways, not envisaged by the current standards, it is necessary to check evacuation time tP and the time of blocking the evacuation ways by calculations and then determine the probability of evacuation REP from the following formulae:

(8)

2.6. РДВ probability is assumed to be equal to: 0.05 – if the space, for which the calculations are conducted, is located not higher

than 45 m and it contains one or several FPS elements of the following type: external evacuation stairs; passages via balconies (loggias) to the adjacent sections of the building; internal stairs, which are not evacuation ways, but leading to a space (part of a

building), where the calculated situation under consideration excludes the emergence of HFF;

Page 42: SNiP RK 2.02!05!2002 (E) Fire Safety of Buildings and Structures

individual rescue equipment for people and protection equipment for the respiratory organs.

0,01 – if the same FPS components are available, but for the space under consideration located above the 16th floor.

If the above resources are unavailable the РДВ probability shall be assumed to be equal to:0.005 – for spaces, located not higher than 45 m.0,001 – for spaces, located higher than 45 m.2.7. FAEMS time lag is determined by the formula

REQUIREMENTS FOR DESIGNING ATRIUMS

1. Communication of spaces and corridors in the underground part of the building is permissible only vestibule-sluices with air overpressure in case of fire.

2. All the spaces, incorporated in the atrium, shall have at least two evacuation ways via a horizontal passage (gallery). If the space is designed for sleeping, the length of the evacuation way via the horizontal passage from the doors of this space to a protected evacuation exit, leading to a staircase, shall be not be more than 30 m. If the space is not used for sleeping, the length of such passage shall not be more than 60 m.

3. Floor structures of atriums shall be of special fire-resistance degree according to 7.16. Floor structures of atriums shall be made of non-combustible materials. The openings in the enclosing structures of atriums shall be glazed with soda-lime glass.

Page 43: SNiP RK 2.02!05!2002 (E) Fire Safety of Buildings and Structures

4. The internal surfaces of atriums shall be finished with non-combustible materials.5. The doors of rooms coming out to the atrium shall be self-closing and have fire-resistance

rating at least 0.5 hr.6. The largest height of atrium with a device of natural smoke protection shall not exceed

15 m.Smoke removal with mechanical actuation for higher atriums, except for air funneling the

upper part of the atrium, shall be provided from different levels according to the design diagram of smoke removal.

Smoke protection system of atriums shall include automatic shutdown of combined extract and input ventilation and air conditioning, if these systems are not operational in a fire protection design.

7. Smoke removal valves shall be opened automatically from signals of smoke and fire detectors, remotedly (from push-buttons, installed in staircases) or manually. Precipitation shall not prevent opening of the valves in roof.

8. A passage via the atrium from spaces not coming out to the atrium is not regarded as an evacuation way.

9. FPS control shall provide different versions (automatic and from CCB FPS) of FPS actuation, depending on the place of fire emergence: in atrium, on galleries, spaces facing the atrium.

10. The area of atriums shall not be divided with fire-break partitions.11. Atrium shall not be higher than 10 floors, the atrium floor can not be lower than 2 floors

below the ground level.
