How are the tank farm units for major hazardous chemical sources classified? The China Academy of Safety Science responded as follows: First, in the case where a tank area consists of 2 or more tank groups, each of which is equipped with a fire dike, and the distance between these tank groups is approximately 30–60 meters, with fire roads or other roads in between, and no other buildings or structures situated in between, according to Section 3.6 “Storage Units” of the “Identification of Major Hazard Sources for Hazardous Chemicals” (GB18218-2018), the area should be divided into units based on each tank group. yunrun.com.cn/tech/4565.html II. A tank area consists of 2 or more storage tank zones; there are fire roads or other roads between these zones, with no other buildings in between. In accordance with Section 3.6 “Storage Units” of the “Identification of Major Hazard Sources for Hazardous Chemicals” (GB18218-2018), units should be established for each group of tanks. III. The tank area consists of 2 tank groups, each of which is equipped with a fire dike; other buildings such as factories, warehouses, or storage areas are located in between them. In accordance with Section 3.6 “Storage Units” of the Standard for Identification of Major Hazard Sources of Hazardous Chemicals (GB18218-2018), units should be established for each tank group ； If such a tank group belongs to the intermediate tank group and is located in the same area as the production facility (plant), it should, in principle, be identified together with the production facility (plant). IV. The hazardous chemicals tank farm is divided into separate units based on the boundaries of the fire dike surrounding the tank farm. In principle, intermediate storage tanks (tank groups) for hazardous chemicals located in the same area as the production facilities (buildings) should be identified together with those production facilities (buildings). Multiple hazardous chemical storage tanks stored in a relatively separate area without fire dikes should be identified as a single unit. http://yunrun.com.cn/upload/202211/13/202211130106515680.png http://yunrun.com.cn/upload/202211/13/202211130107381906.png
