Fire separation distance between liquefied hydrocarbon storage tanks and Class B and C workshops

The last edit to this post was made by Xun Hua on 2012-4-19 at 12:34. The regulations do not specify the fire separation distance between liquefied hydrocarbon storage tanks and buildings of categories D and E; only the fire separation distance from buildings of categories A, B, and C is specified； The building codes also do not provide clear guidelines regarding liquefied hydrocarbons. Discussion 1: How should the fire protection distance between liquefied hydrocarbon storage tanks constructed in accordance with stone code standards and buildings of Class D and E be determined? Discussion 2: The building codes do not provide clear guidelines regarding liquefied hydrocarbons; according to experts, the fire separation requirements for such substances can be based on the stone-related codes. Since in building codes the distance required for liquid hydrogen can be reduced by 25% compared to that for liquefied petroleum gas, can the distance required for liquefied hydrocarbons also be reduced by 25% compared to that for liquefied petroleum gas?
Class D and Class E factories generally have open-flame equipment, so I think they should be considered as such. What are the purposes of the Class D and Class E factories you mentioned?
I am referring to Class D and Class E factories that do not have open-flame equipment; in those with open flames, the calculation starts from the location of the open flame. Moreover, Classes D and E do not necessarily involve an open flame.
How is the fire separation distance determined in the absence of an open flame? How is the fire separation distance determined in the presence of an open flame?
Personally, I think it should be determined based on the control room, cabinet room, substation, laboratory, and office. Because you cannot be sure that there may be open flames, red-hot surfaces, or smoking in Class D and E factories, and there may also be electric sparks generated by electrical equipment. You mentioned what the Class D and Class E buildings in the plant areas of petrochemical enterprises are used for, but despite asking multiple times, you deliberately avoided giving an answer.
For Class D warehouses (without open flames), what is the fire separation distance? The stone regulations do not specify exactly what the building regulations require
For larger storage tanks, the range of thermal radiation in the event of a liquefied hydrocarbon tank fire should also be taken into consideration.
