In accordance with GB 50160 and GB 51283, the accident water tank should be located in a low area at the edge of the plant site; distances from it to open-flame areas and flares are specified, while no fire separation distances from other facilities are required. As explained in Article 4.2.8A of GB 50160,； 2. During the recent safety review, in accordance with Article 6.6.3, Paragraph 4 of GB/T 50483-2019, the experts required that the accident tank be designed as a Class C tank ； The specifications before and after are significantly different; the former is clear, specifying only distance requirements from open flames and flares, with no other regulations ； But the latter requires design in accordance with Category C standards; it specifies how devices or facilities of Category C should be designed and what distance requirements apply, yet it does not provide any regulations Now that all expert requirements must be met, how can the accident tank be designed as a Class C facility? The regulations regarding fire hazard categories are generally clearly specified in fire protection codes such as GB 50016, GB 50160, and GB 51283. GB 50160 and GB 51283 contain specific provisions for accident tanks; should design be carried out in accordance with Category C as specified in GB 50016? Class C tank farm? Class C warehouse? Is it still a Class C factory building? Or something else?
Could you tell me what book 4.2.8 refers to? I’d like to buy a book to study* it, thank you.
There is no contradiction; the accident pool is a structure, and fire separation requirements are not governed by building codes. Regarding the implementation of petrochemical regulations by petrochemical enterprises, regardless of how other standards define the categories of accident ponds, when it comes to applying fire separation requirements, the petrochemical regulations specify distances from open flames, while other standards do not have such requirements. Requiring a Class C design for the accident tank has an impact on the selection of certain equipment within the accident tank itself, but it has no effect on the fire separation distances.
