General layout safety distance

According to Document No. 2013[76] issued by the State Administration of Work Safety, for construction projects that involve hazardous chemicals and processes that are subject to strict supervision in the first and second batches, as well as those that constitute major hazard sources, the fire separation distances must meet the requirements set out in eight relevant standards. In the case of facilities for producing hydrogen through methanol cracking, both methanol and hydrogen fall under the category of hazardous chemicals that are subject to strict supervision in the first batch, and methanol cracking is considered a hazardous process; therefore, the fire separation distances must comply with the requirements of GB50160-2008. Additionally, this construction project involves the filling of gases, primarily oxygen, nitrogen, argon, and carbon dioxide. Since GB50160-2008 already applies to this project, the distances between oxygen and the buildings, structures, and walls surrounding the facility must also comply with the requirements of GB50160-2008. Is this reasonable?
There’s nothing unreasonable about it; your way of thinking is still stuck in old concepts. Fire prevention is a matter of thermal radiation; the thermal radiation produced when the same medium burns is identical. The larger the storage volume, the more dangerous it is; the greater the variety, the more dangerous it is. It means the consequences of the accident are dangerous.
