What are the distance requirements between outdoor equipment and its building? ?
Thread Content
Due to the large number of equipment units, the intermediate storage tank is placed outdoors and stores Class A substances; the factory building is also classified as a Class A building. How should the distance between the equipment and such a building be calculated? ? There are many outdoor intermediate storage tanks, arranged in four rows; is it feasible to construct a fire dike? ? According to building codes, Class A storage tanks are grouped in pairs; what is the definition of a tank group? Is it available here? ? ?
According to the Code for Fire Protection Design of Buildings GB50016-2006, the required safety distance between Class A factories is 12 meters. As for oil tank areas, there are specific design standards for such areas, which outline these requirements in detail; you can take a look at them yourself
It’s not an oil tank area! ! ! The answer upstairs is very unsatisfactory! ! Are workshop equipment placed outdoors, as long as the workshop meets the process requirements? ? ? ? ?
For questions like the one raised by the original poster, such issues are indeed common in design work. For ordinary chemical enterprises, design should be carried out in accordance with the Code for Fire Protection Design of Buildings GB50016-2006; according to this code, storage tanks with a volume of over 1 cubic meter are considered part of the tank area. The Code for Fire Protection Design of Buildings does not mention intermediate tanks, so I believe it is inappropriate to use them, as there is no basis for doing so. On the other hand, the Code for Fire Protection Design of Petrochemical Enterprises specifies requirements regarding the distance between tanks. Therefore, it is first necessary to determine whether your overall design falls within the scope of the Code for Fire Protection Design of Petrochemical Enterprises. If not, then design should be carried out in accordance with the Code for Fire Protection Design of Buildings. Class A storage tanks cannot exceed two rows. The fire separation distance between tank groups is determined in accordance with Article 4.2.3 of the Code for Fire Protection Design of Buildings.
First, it is necessary to determine whether your facility falls under the scope of the Petrochemical Regulations. If it does, it can be treated as a facility tank, and its layout should be arranged in accordance with the fire separation requirements specified in clause 4.2.28. If it is not covered by the Petrochemical Regulations, then the Building Code must be applied, with the fire separation requirements outlined in clause 4.2.1 used for planning.
According to the building codes regarding the distance between storage areas and workshops, Class A storage tanks and Class A workshops must be at least 25 meters apart. In my opinion, the distance between the intermediate storage tank area and the workshop need not be restricted, as long as the process requirements are met; however, for safety reasons, a fire dike must still be installed. Furthermore, the storage capacity of the intermediate tank area must be limited to not exceeding the amount required by the workshop for one day and one night. The plant site also has a separate, centralized large-scale storage tank area. For the original poster’s reference.
The explanation upstairs is very clear, thank you @!
It should comply with petrochemical standards, including the requirements for storage tanks in the plant, with a spacing of 9 meters. Building codes often do not provide comprehensive regulations for situations in chemical enterprises.
