USSR State Committee on affairs construction (Gosstroy USSR)	Construction regulations	SNIP 2.01.02-85 *
Fire rules	Instead SNIP II-2-80

These rules must be observed in the development of projects of buildings and structures.

These rules set fire technical classification of buildings and structures, their elements, structures, materials, and general fire protection requirements for the design and planning solutions of rooms, buildings and structures for various purposes.

These rules are supplemented and refined by fire requirements set out in Part 2 of SNIP and other regulatory texts.1 approved or agreed by Gosstroy of USSR.

_____________

1 Hereinafter - "to snip part 2".

In these norms accepted the terms and definitions given in ST SEV 383-76 and GOST 12.1.033-81 *.

1. FIRE OF BUILDINGS, STRUCTURES AND
fire compartments

1.1 *. Buildings, structures and parts of buildings and sooruzheniy1 isolated fire walls Type 1 (fire compartments), divided by degree of fire resistance.The degree of fire resistance of buildings is determined by the minimum limits of fire resistance of building structures (listed in Table. 1) and the maximum limits fire spread to these structures.

___________

1 Hereinafter - "building".

fire resistance limits of self-supporting walls, taken into account in calculating the stiffness and stability of the building, you need to take c.Table 2.1.

Where Table.1 construction of fire resistance minimum limit is 0.25 hours, allowed to use unprotected steel structures, and in remote areas of construction, moreover, the outer walling of aluminum sheets, regardless of their actual fire rating.

in Building II degree of fire resistance of industrial and warehouse purposes may be used with a column of fire resistance limit of 0.75 hours.

allowed in buildings of all degrees of fire resistance apply gypsum boards according to GOST 6266-89 for lining of metal structures in order to improve their fire resistance.

in buildings of all degrees of fire resistance for the allocation of jobs within the premises may be used partitions (glazed or with mesh at the height of the dull pain is not 1.2 m, collapsible and sliding) with non-normed outside fire resistance and limits the spread of fire.

1.2 *. degree of fire resistance of buildings was adopted in the project, depending on their destination, category by explosion and fire hazard, the number of storeys, floor area within the fire compartment, except in cases specified in the regulations.

Exemplary structural characteristics of buildings, depending on their degree of fire resistance given in Informative Annex 2.

1.3. fire resistance of building structures are defined by ST SEV 1000-78.

limits the spread of fire on building structures are determined by the method given in the mandatory appendix 1.

1.4 *. Construction materials flammability (flammability) are divided into three groups: non-flammable (non-combustible), slow-burning (nonflammable) and combustible (flammable) 1.

_____________

1 Hereinafter - "combustibility", "non-flammable", "slow-burning""flammable".

Group of combustibility of building materials are determined by the ST SEV 382-76 and ST SEV 2437-80.

Classification of building materials and structures on the toxicity of combustion products and smoke-forming capacity during combustion is made in accordance with GOST 12.1.004-89.

1.5. frames of false ceilings must be made of non-combustible materials.

Filling allowed to perform suspended ceilings of combustible materials, except for the filling of suspended ceilings in common corridors, stairways, stairwells, lobbies, halls and foyers of buildings I - IVa degrees of fire resistance.

In the space above the false ceiling is not allowed to provide accommodation canals and pipelines for the transport of flammable gases, dust-air mixtures of liquids and materials.

In the application of false ceilings to improve the fire resistance of floors and coatings limit ceiling fire resistance or coating with suspended ceilings should be determined for a single design, and limit the spread of fire -. Separately for covering or coating andfalse ceiling. at the same time limit the spread of fire on such a false ceiling must be no more than set for the protected overlap or cover. ceilings should not have openings, and communications, are located above the suspended ceiling should be made of non-combustible materials.

1.6 *. in buildings I and II degrees of fire resistance may be used partitions of gypsum boards according to GOST 6266-89 with a frame made of non-combustible materials with a fire-resistance rating of not less than 1, respectively, and 0.5 h. in the common hallways, stairwells, lobbies, halls andlobby plasterboard is not allowed to paint combustible paints.
