Legal basis: Code for Fire Protection Design of Buildings

Article 1 When the total length of an L-shaped building exceeds 220m or the length along the street exceeds150m, a fire escape through the building shall be set up. If the total length is 180m and the length along the street is 100 (only look at one side), there is no need to set up a fire lane to cross the building.

The second high-rise building must first set up a circular fire lane, that is, there must be a fire lane around this L-shaped building. If this is not possible, it should be relaxed to set fire lanes along two long sides (that is, two 100 meters). The total length does not exceed 220 meters.

Article 3 The clear width and clear height of the fire truck passage shall not be less than 4m.

Article 4 Fire exits for evacuation shall have different regulations according to different buildings.

Article 5 The clear width of the fire escape should not be less than 3.5 meters, and it should be kept clear, because the width of the fire truck is about 2.5 meters.

Article 6 The clear width of emergency exits and room evacuation doors shall not be less than 0.9m, and the clear width of evacuation walkways and stairs shall not be less than1.1m; For a unit house with no more than 6 floors, when railings are set on one side of the evacuation stairs, the minimum clear width should not be less than1.0m.
