1 General Provisions
1.0.1 This code is formulated with a view to preventing fire accidents in buildings,
reducing fire hazards and protecting personal and property safety.
1.0.2 This code is applicable to the following constructed, renovated and extended
buildings:
1 Factory-buildings;
2 Storages;
3 Civil buildings;
4 Class A, B, C liquid tanks (tank farm);
5 Combustible and combustion-supporting gas tanks (tank farm);
6 Stackyard for combustibles;
7 City road tunnels.
If special national standards are available, the fire protection design of buildings for
civil air defense engineering, petroleum and natural gas engineering, petrochemical
engineering, thermal power plants and substations should comply with such
standards.
1.0.3 This code is not applicable to the fire protection design of buildings such as
factory-buildings (storages) for gunpowder, explosive and their products as well as
fireworks and firecrackers.
1.0.4 Where occupancies for different purposes are arranged in the same building,
fire separation shall be provided between them. The fire protection design for this
building and their functional occupancies shall be determined according to the
relevant requirements of this code.
1.0.5 The fire protection design of buildings shall comply with the relevant national
principles and policies, and guarantee, on the whole, safety and usability, advanced
technology as well as economy and rationality according to the characteristics of
buildings and fire hazards in them.
1.0.6 In addition to meeting the requirements of this code, the buildings with height
single-storey Category D factory-buildings with building area not greater than
1,000m2, the fire resistance class may adopt Class III.
3.2.4 As for the buildings using or storing particularly valuable equipment or
articles such as machinery, instruments and apparatuses, the fire resistance
class shall not be less than Class II.
3.2.5 The fire resistance class of boiler house shall not be less than Class II. In case
of coal-fired boiler house with total evaporation not larger than 4t/h, its fire resistance
class may adopt Class III.
3.2.6 The fire resistance class of oil immersed transformer room and high-voltage
distribution device room shall not be less than Class II, and other fire protection
design shall meet the requirements of current national standard "Code for Design of
Fire Protection for Fossil Fuel Power Plants and Substations" (GB 50229) and other
relevant standards.
3.2.7 The fire resistance class of high rack storages, high-rise storages,
Category A storages, multi-storey Category B storages and multi-storey
Category C storages storing combustible liquid shall not be less than Class II.
The fire resistance class of single-storey Category B storages, single-storey
Category C storages, multi-storey Category C storages storing combustible
solids and multi-storey Categories D and E storages shall not be less than
Class III.
3.2.8 The fire resistance class of grain silos shall not be less than Class II; the grain
silo with Class II fire resistance may adopt steel silo.
The fire resistance class of grain storehouses shall not be less than Class III; the bulk
grain storehouses with Class II fire resistance may be adopted with metal
load-bearing elements without fire protection.
3.2.9 The fire resistance rating of fire walls in Categories A and B
factory-buildings and Categories A, B and C storages shall not be less than
4.00h.
3.2.10 The fire resistance rating of columns in single-storey factory-buildings
(storages) with Class I or II fire resistance shall not be less than 2.50h and 2.00h
respectively.
3.2.11 As for the Class I fire resistance single-/multi-storey factory-buildings
(storages) with full protection of sprinkler system, the fire resistance rating of their roof
