Fire resistance level
First, second level
, second level
Note: ① The fire separation distance should be calculated according to the closest distance between the outer walls of adjacent buildings. If there are protruding combustion components on the outer wall, it should be calculated from the outer edge of the protruding part.
② The fire separation distance between Class A factories that emit flammable gas and flammable steam or between other factories (warehouses) should be increased by 2m according to this table, and the fire separation distance with civil buildings should not be less than 25m. ③ The fire separation distance between Class A warehouses and factories (warehouses) with the first, second and third fire resistance grades shall not be less than 12m, and the fire separation distance between Class A and Class B warehouses and civil buildings shall not be less than 25m. Article 4.2.2 The fire separation distance between factories (warehouses) and civil buildings may be implemented in accordance with the provisions of Article 4.2.1 of this Code.
Article 4.2.3 When the adjacent higher outer wall of two factories (warehouses) is a fire wall or the two adjacent outer walls are non-combustible solid walls, and there is no combustible eaves, the fire separation distance is not limited. However, the fire separation distance between Class A factories should not be less than 4m. Article 4.2.4 When the factory is equipped with outdoor equipment for chemical flammable materials, the fire separation distance between its outer wall and the outer wall of the outdoor equipment of the adjacent factory should not be less than 8m. The fire separation distance between the outer wall of the outdoor equipment and the outer wall of the adjacent factory should not be less than the provisions of Table 4.2.1 of this Code.
Note: Outdoor equipment should be determined according to the buildings with the first and second fire resistance grades. Article 4.2.5
, when the total floor area of several factory buildings with the first, second and third fire resistance grades does not exceed the allowable floor area of a building specified in Article 4.1.1 of this Code, they can be arranged in groups. The distance between factory buildings in a group should not be less than 4m, and the fire separation distance between groups or between groups and adjacent buildings should comply with the provisions of Article 4.2.1 of this Code.
