1.0.1 This code is formulated with a view to preventing and reducing building fire hazards and safeguarding people's life and property.
1.0.2 This code shall be applicable to the construction, extension and renovation of the buildings specified as follows:
1 Residential buildings of 9 stories or below (including residential buildings with commercial service facilities);
2 Public buildings not over 24m high;
3 Single story public buildings over 24m high;
4 Underground and semi-underground buildings (including basement and semi-basement of the building);
5 Factory building;
6 Storage;
7 Storage tank (tank farm) for Class A, B and C liquid;
8 Storage tank (tank farm) for combustible and combustion-supporting gas;
9 Combustible stackyard;
10 City traffic tunnel.
Note: 1 Measurement of the building height: When the roof is slope, the height of the building shall be measured from the design ground level outside the building to the eaves; when the roof is flat (including the flat roof with parapet wall), the height of the building shall be measured from the design ground level outside of the building to the surface of the roof; when the building has various roof shapes, the height of the building shall be measured respectively with the same measurement method and take the greatest value. The sticking out constructions such as observation tower, cooling tower, water tank room, microwave antenna room or equipment, elevator machine room, air and smoke exhaust fan room, staircase exit etc. on the roof may not be counted in the building height.
2 Measurement of the building stones: The basement and semi-basement with its top slab not more than 1.5m high above the design ground level outside of the building, the bicycle storage space, storage and open space not more than 2.2m high at the lower part of the building, and the local equipment room, staircase etc. above the roof may not be counted in the stories. The apartment on the top of the building with two stories as one unit can be considered as one story. The two-story apartment not on the top of the building and the apartment on the top of the building with more than two stories as one unit shall be counted in the stories.
1.0.3 This code is not applicable to the fire protection design of explosive plants (storage) and firecrackers work shops (storage).
If there are current national standards for the fire protection design of civil air defense works, oil and gas installations, petrochemical plants, thermal power plants or transformer substations, it should meet the special requirements of those standards.
1.0.4 The design of building fire protection shall be consistent with the relevant national policies, and the designer shall consider the overall situation to achieve the purpose of ensuring safety, serviceability, technical superiority and economy.
1.0.5 The design of building fire protection shall comply with the stipulation of this code and it shall furthermore comply with the relevant current national codes.
