Regarding the location of the tank farm control room
Thread Content
We have a project where the client wants the cabinet room to be located in an auxiliary building attached to a Class A workshop. If this area falls within the explosion-proof zone, do we only need to consider explosion-proof requirements?
Now, cabinets are also not allowed to be placed adjacent to Class A workshops. If they are to be located in explosion-proof areas, blast resistance calculations must be carried out, and the building structure of the cabinet room must be designed in accordance with the blast resistance requirements. I’m not sure the requirements vary from province to province; Zhejiang does have this requirement.
For explosion-proof areas, blast resistance calculations must be performed. Based on the distance from the equipment, the extent of the potential explosion zone is determined, and it is then decided how many levels of blast-resistant structures are required for the cabinet rooms. In cases where blast resistance is necessary, a separate blast-resistant building should be constructed; placing such a structure as an auxiliary building within a Class A workshop would violate regulations.
Could you let me know which specific regulations are referenced? Thank you!~
4.0.2 The on-site cabinet room should be located as close as possible to the process unit it serves, and must be situated outside areas prone to explosions. When it is installed in an additional structure, the floor beneath the movable floor of the on-site cabinet room should be at a higher level than the outdoor ground, with the height difference being no less than 0.6 m. 4.0.3 The on-site cabinet room should preferably be designed as a separate structure. 4.0.4 The height of the on-site cabinet room for blast-resistant structures should be one floor, and should not exceed two floors. 4.0.7 For chemical plants with explosion hazards, the on-site cabinet rooms shall be designed with explosion-resistant structures

There is an explosion-proof wall in between the Class A workshop and the other area
Between the auxiliary room and Area A, there is a flameproof wall
