For the unloading of Class A liquids and the transfer pump house, can a semi-underground pump house be used?

I checked the \"Code for Fire Protection Design of Petrochemical Enterprises\" (GB50160-2008) and the \"Code for Design of Oil Depots\" (GB50074-2014), but could not find any design specifications related to pump rooms. The petrochemical fire protection codes do not provide specific regulations regarding the layout of pump rooms, and there is also only limited information on the placement of pumps ； Chapter 7 of the oil depot design specifications, titled “Pumps for flammable and combustible liquids,” consists of 2.5 pages in total; it only states that above-ground pump houses are preferable, with no mention at all of underground or semi-underground pump houses ； Furthermore, Chapter 4 \"Pump house types and architectural requirements\" of the \"Design Code for Pump Houses in Petrochemical Enterprises\" (SH/T 3014-2002) also does not mention semi-underground pump houses. So now I’m a bit puzzled: is the semi-underground pump room a product of history, and has the industry never taken it seriously?

Whether a semi-underground design can be used depends on the density of the medium. ”No flammable gases should accumulate inside the pit. If the density is greater than that of air, it is best not to install it in a semi-underground location. Additionally, the layout plan for this equipment does not meet fire safety regulations; the area where vehicles are loaded and unloaded is too close to the pump room. The distance between areas where Class A vehicles are loaded and unloaded and Class A pump rooms should be at least 15 meters

A semi-underground pump room can be used, provided that ventilation facilities and gas detectors are installed.

GB50016 3.3.4

Thank you. According to Code for Building Design 3.3.4, production facilities (warehouses) of Class A and B should not be located underground or semi-underground. It’s the pump room now, and it doesn’t seem to have any explicit prohibition.

It is recommended to follow clause 3.3.4 and not install any underground or semi-underground structures

I wonder if there are any actual examples of semi-underground unloading pump rooms for Class A and B liquids? I used to work on a small refinery plant before, but I didn’t pay attention to these areas back then either. Please ask someone who works in factories or enterprises to explain.

According to Code for Building Design 3.3.4, Class A and Class B production facilities (warehouses) should not be located underground or semi-underground, mainly because accidents are likely to occur there, and it is difficult to carry out rescue operations in such cases. Although this clause does not explicitly state it as a pump room, a pump room can actually be considered a production facility as well; therefore, based on the meaning of the regulatory provisions, it is recommended not to locate it in a semi-underground area.

Thank you to all the sea friends upstairs; safety first! Then, let’s not consider establishing a semi-underground pump room for now. However, in the case of this situation, based on the floor plan on the first floor, should the unloading of materials and their delivery to the equipment be considered separately? That is, the material within the tank cluster needs to be unloaded at the unloading site, using unloading pumps to transfer it into the tanks, and the pipelines must cross the road in order to do so ； And for the transfer of materials within the tank cluster to the equipment, should transfer pumps be installed right next to the storage tanks, with the delivery pipelines then crossing the road to reach the equipment area below? I hope all the sailors can discuss this together! Thank you. (Also, due to my limited wealth, I’m unable to give ratings or rewards to the fellow sailors who have replied; I’m sorry＾—＾)
