Is a 100-ton benzene underground tank considered a major hazard source?

Is a 100-ton benzene underground tank considered a major source of danger? The underground tank has improved the safety factor. Should the standard be lowered?* * There are corresponding standards. In addition, gas stations and underground tanks at gas filling stations are not major sources of danger.
According to the definition of major hazard sources in "GB18218-2000 Identification of Major Hazard Sources": 3.5 Major hazard installations are units that produce, process, transport, use or store hazardous substances on a long-term or temporary basis, and the quantity of hazardous substances is equal to or exceeds the critical amount. And the name and storage amount of toxic substances included in the 46th pure benzene, the critical amount in the production area is 20 tons, and the critical amount in the storage area is 50 tons. Therefore, the pure benzene storage tank you mentioned also constitutes a major source of danger. This has nothing to do with whether it is a buried tank or not.
Regardless of the storage method, it is a major source of danger.
The moderator of hw197358 on the second floor has made it very clear. I would like to add that at present* * The criterion for whether hazardous chemicals constitute a major hazard source is mainly the critical amount. As long as it is equal to or exceeds the critical amount, it constitutes a major hazard source! If measures such as underground tanks are taken to improve their safety factors, the level of major hazard sources will be reduced during the major hazard source assessment (currently * * There is no relevant standard yet)!
