Understanding the fire separation distance of above-ground storage tanks for flammable liquids
Thread Content
The fire separation distance between adjacent flammable liquid above-ground storage tanks in a tank group. For storage tanks with a single tank volume greater than 1000m3, take the larger value of diameter or height. Does the height here need to be multiplied by 0.4 or 0.6? Or directly compare 1 times the height and 0.4 or 0.6 times the diameter?
Table 6.2.8 Fire separation distance categories for adjacent flammable liquid above-ground storage tanks in the tank group. Tank type: Fixed roof tank, floating roof tank, internal floating roof tank, horizontal tank ≤1000m3 >1000m3 Category A, B, B 0.75D 0.6D 0.4D 0.8m Category C, A 0.4D Category C, B 2m 5m Note: 1. D in the table is the diameter of the adjacent larger tank. For storage tanks with a single tank volume greater than 1000m3, the larger value of diameter or height shall be used. Therefore, for a storage tank with a single tank volume greater than 1000m3, the larger value of diameter or height must be multiplied by 0.4 or 0.6.
