Is the approval of workshop buildings in the petrochemical industry related to the equipment foundations within those buildings?

Of course there’s a relationship! In the petrochemical industry, plant approval is closely linked to equipment foundations; your colleague is right. In simple terms, the approval process for a factory building doesn’t consider only the building itself; it takes into account all the equipment, pipelines, and safety passages that will be installed within it as well. Especially in the petrochemical industry, safety requirements are extremely high; detailed information on equipment layout and other basic details must be provided during the approval process, otherwise approval will not be granted at all. **Regarding the few points you mentioned: **1.** A basic layout diagram of the equipment is necessary. The approval authorities need to verify that the equipment can fit there, that the foundation has sufficient load-bearing capacity, that the pipelines can be connected, and that there is enough space for maintenance and safety purposes. The location of the motors and the cable trenches need to be planned in advance; otherwise, it will be difficult to install the equipment later on, or the safety distances won’t be sufficient, making repairs more troublesome. 2. **Water, electricity, heating, and ventilation apply not only to public areas** – the water, electricity in chemical plants are needed not only for lighting and fire protection but also to meet the requirements of process equipment. Things such as equipment cooling water, power for industrial processes, and steam pipelines all need to be planned carefully during the plant design phase; otherwise, retrofitting costs will be high and safety hazards are likely to arise. 3. **What information should be referred to for the distance of safety passages?** In the petrochemical industry, the distance of safety passages is primarily determined based on two standards: – **“Fire Protection Design Code for Petrochemical Enterprises” (GB 50160)**: This is the most important standard, as it specifies in detail the requirements regarding equipment spacing, passage widths, and fire protection measures. - **\"Code for Fire Protection Design of Buildings\" (GB 50016): Although it focuses on buildings, chemical plant facilities must also comply with the requirements regarding fire exits as stipulated in this code. The specific values depend on the type of equipment and the level of hazard; for example, safety distances vary for reactors, storage tanks, incinerators, and so on. It is recommended to consult GB 50160 directly, or have the design institute do the calculations for you. **To sum up: **The approval process for chemical plants is a systematic effort; the equipment foundation and plant design must be submitted for approval together.** Don’t think it’s a hassle – the more detailed the planning is in the early stage, the less trouble you’ll have later on. If you’re not sure, communicate more with the design institute – they are more familiar with the regulatory requirements. .

Thank you for your reply. Are the requirements you mentioned specific to the petrochemical industry, or are they applicable to all industries? I understand that the risk level of the fire safety passage equipment you mentioned falls under the scope of approvals for factory buildings ； But I really can’t understand everything related to the factory building (such as the load-bearing capacity of the equipment, whether the equipment can fit in, the location of the motors, the cable trays, and the power requirements for the equipment’s cooling system) ； If a factory’s equipment is to be upgraded, cannot the model and location of the motors be changed, as long as safety passages and explosion-proof standards remain unchanged?
