bg2.png When the fire separation distance is insufficient, it is necessary to check whether the building has adopted reinforcement measures that meet the requirements of the current **Fire Protection Technical Standards for Engineering Construction. If the requirements still cannot be met due to various reasons such as site constraints, factories and warehouses can take certain appropriate measures depending on the specific situation: 1) Change the nature of production or use within the building in order to reduce its fire risk as much as possible； Modify the fire resistance of certain structural elements of the building to increase its fire rating. 2) Adjust some of the production process flows in the manufacturing facilities and the quantity of items stored in the warehouses ； Adjust the fire resistance and combustion performance of certain components. 3) Convert the ordinary exterior walls of the building into firewalls. 4) Demolish some existing old buildings with low fire resistance ratings, small floor areas, limited functionality, and those located adjacent to new buildings. 5) Set up a separate firewall, etc. The measures taken by the Civil Construction Party change 2) and 3) to the following: Structural modifications are carried out on the existing office buildings to ensure that their fire resistance rating is at least level two; meanwhile, the outer wall on the higher side of these two buildings is modified into a fire wall without any doors or windows, or the outer wall within a height of 15 meters or less on the roof of the lower building adjacent to them is modified into a fire wall without any doors or windows. Once this is done, there are no restrictions regarding the required fire separation distances.
