Can a 1000-cubic-meter benzene tank be designed in accordance with GB50341?

:(Benzene is extremely hazardous, right? It’s not possible to specify an extremely high level in 50341 – what should be done?)
Atmospheric pressure vessels for extremely hazardous media should be constructed in accordance with GB150 requirements
If it falls within the scope applicable to 150, it should be calculated according to 150.
It is impractical to design and manufacture large storage tanks in accordance with GB/T150. Although GB50341 is not applicable to media with extremely high or high toxicity levels, in practice most designs follow the GB50341 standard, with additional conditions added during the design process, such as the installation of gas seals……
The classification of toxicity levels is still based on HG20660-2000; there is an answer available on the website of the General Administration of Quality Supervision, Inspection and Quarantine. Benzene is not a highly hazardous medium; all our 1000-liter benzene tanks are designed in accordance with standard 50341.
It can be said that pressure vessels refer to HG20660-2010, but GB50341 does not reference it
