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

GB 50016-2014 (2018 Edition) single-storey Category D factory-buildings with building area not greater than

1,000m

2 , the fire resistance class may adopt Class III.

2 As for the multi-storey textile factory-buildings with Class I fire resistance and

single-/multi-storey textile factory-buildings with Class II fire resistance other than the bast fiber factory-buildings, the maximum permissible building area of each fire compartment may be increased by 0.5 times according to those specified in this table. However, the raw cotton unpacking and blowing rooms shall be separated from other parts in the factory-buildings with fire partition walls with fire resistance rating not less than 2.50h; if it is required to set doors, windows or openings, Class A fire doors and windows shall be installed.

3 As for the single-/multi-storey combined paper factory-buildings with Class I or II

fire resistance, the maximum permissible building area of each fire compartment may be increased by 1.5 times according to those specified in this table. As for the combined wet paper factory-buildings with Class I or II fire resistance, if automatic fire extinguishing system is set in the dryer hood of paper machine and effective fire extinguishing facilities are set at the finished section for the purpose of fire protection, the maximum permissible building area of each fire compartment may be determined according to the process requirements.

4 As for the operation tower of cereal silo with Class I or II fire resistance, if the number of workers at each storey does not exceed 2, the number of storeys is not limited.

5 The production rooms in combined cigarette factory-buildings with Class I or II

fire resistance, like rooms for raw material, stock, grouping formulation, silk reeling, silk storing and rolling package, auxiliary material turnover, temporary storage of finished products, and tobacco shred expansion by carbon dioxide, shall be divided into independent fire separation units, and may be separated by fire walls when the process conditions permit. Thereinto, the silk reeling, silk storing and rolling package rooms may divided into one fire compartment and the maximum permissible building area of each fire compartment may be determined according to the process requirements, but the silk reeling, silk storing and rolling package rooms shall be separated by fire partition walls and floor slabs with fire resistance rating not less than 2.00h and 1.00h respectively.

In addition, proper measures shall be taken at the openings between horizontal and vertical fire separations in the factory-buildings to prevent fire spreading.

6 As for the operation platform and repair platform in factory-buildings, if the

number of their users is less than 10, the platform area may not be counted into the building area of local fire compartment.

7 "-" means “not allowed”.

GB 50016-2014 (2018 Edition)

3.3.3 Where automatic fire extinguishing system is arranged in the factory-buildings, the maximum permissible building area of each fire compartment may be increased by 1.0 time according to those specified in 3.3.1 of this code. Where automatic fire extinguishing system is arranged in Categories D and E over-ground factory-buildings, the maximum permissible building area of each fire compartment is not limited. Where local automatic fire extinguishing systems are arranged in the factory-buildings, the increased area of their fire compartment may be calculated as 1.0 times of this local area.

Where automatic fire extinguishing system is arranged in the storages (except the fire compartments in the refrigeration storage), the maximum permissible occupied area of each storage and the maximum permissible building area of each fire compartment may be increased by 1.0 time according to those specified in 3.3.2 of this code.

3.3.4 Categories A and B production occupancies (storages) shall not be arranged underground or semi-underground.

3.3.5 Staff dormitory must not be arranged in the factory-buildings.

Offices and resting rooms shall not be arranged in Categories A and B factory-buildings; if offices and resting rooms must be adjacent to the factory-buildings, they shall reach Class II fire resistance at least and blast walls with fire resistance rating not less than 3.00h shall be used to separate them from the factory-buildings; in addition, independent safety-exits shall be arranged.

Where offices and resting rooms are arranged in Category C factory-buildings, fire partition walls with fire resistance rating not less than 2.50h and floor slab with fire resistance rating not less than 1.00h shall be used to separate them from other positions; in addition, at least 1 independent safety-exit shall be arranged. Where it is needed to arrange interconnected doors on partition wall,

Class B fire doors shall be adopted.

3.3.6 Where intermediate storages are arranged in the factory-buildings, the following requirements shall be met:

1 Categories A and B intermediate storages shall be arranged adjacent to external wall, their storage capacity should not exceed the demand for one day and night;

2 Categories A, B and C intermediate storages shall adopt fire walls and non-combustible floor slabs with fire resistance rating not less than 1.50 h
