Do the atmospheric pressure intermediate storage tank groups for flammable liquids within the facility need to comply with the \"Safety Management Specifications for Atmospheric Pressure Storage Tank Areas of Chemical Enterprises\" AQ3063-2025?

The issue comes from the WeChat official account “Zhuan An’s Masterpieces”. Written by Da Yu Hai Tang, published on May 4, 2026; the main idea is as follows: Do the atmospheric pressure intermediate storage tank groups for flammable liquids in such facilities need to comply with the \"Safety Management Specifications for Atmospheric Pressure Storage Tank Areas of Chemical Enterprises\" AQ3063-2025? The answer is no. After the issuance and implementation of AQ3059-2023 \"Safety Management Specifications for Liquefied Hydrocarbon Storage Areas in Chemical Enterprises,\" many people wondered whether the intermediate liquefied hydrocarbon storage tanks within such facilities needed to comply with the requirements outlined in AQ3059. In response to this question, the standard’s drafting body issued a separate response. The storage tanks (sets) of a plant refer to those that do not directly participate in the chemical processing during normal operation of the plant. However, due to process requirements and the need to maintain balance in production, as well as for storing products or raw materials, such tanks (sets) must be installed within the plant. They are considered part of the plant’s process equipment tanks and do not belong to the tank farm. The author (Dayu Haitang) consulted experts involved in the formulation of these standards to find out whether the atmospheric-pressure intermediate storage tank groups for flammable liquids within a plant need to comply with the \"Safety Management Specifications for Atmospheric-Pressure Storage Tank Areas of Chemical Enterprises\" AQ3063-2025. This issue is similar to that addressed in the reply to AQ3059; the scope of application of AQ3063-2025 does not include the storage tanks (groups) within a plant. However, the author (Dayu Haitang) suggests that when the tank groups within the facility are arranged on the periphery of the facility on a certain scale, in addition to meeting the requirements of the main standard specifications such as those set by the petrochemical industry, some safety design aspects can take into account the requirements specified in AQ3063. What do you all think?
