A safety distance of 5 meters must be maintained between the hydrochloric acid and liquid alkali tanks. Should the height of the retaining wall be 1.2 meters?

During today’s inspection, the experts suggested that for the 10-cubic-meter hydrochloric acid tank and the 10-cubic-meter lye tank, as well as the tanks containing hydrochloric acid (31) and lye (30), a safety distance of 5 meters should be maintained. Additionally, the enclosures surrounding these tanks should be at a height of 1.2 meters. Is this something the experts said arbitrarily, or is it based on some standards? Everyone, please look for the specifications
There is no requirement to reduce the spacing within this
GB50160-2018, Clause 6.2.10 – I’m not sure whether experts refer to this clause； If so, I personally believe the expert’s citation is incorrect. There have been many discussions in Honkawa regarding the safety distance requirements for acid and alkali storage tanks; it is recommended to do some research on this topic.
There are no specific requirements regarding the fire separation distance for acid and alkali tanks; it is sufficient to place them in different compartments within the same tank group for daily operations. If the material of the acid tank is not resistant to alkalis, or vice versa, the ideal separation distance should be half the height of the tank. According to the interpretation of clause 6.2.13 of the petrochemical regulations, this distance represents the maximum leakage and splashing range for tanks under normal pressure. It should also be noted that if a reaction between acidic and alkaline liquids occurs, it can lead to dangerous consequences, such as the generation of chlorine gas; in such cases, the drainage systems must be separated.
Standardized support is needed; it should not be expanded arbitrarily
Both 6.2.8 and 6.2.10 refer to flammable liquids; hydrochloric acid and liquid alkalis are not flammable
