I would like to know how many provinces have started to implement the "four-zone separation" of chemical enterprises?
Thread Content
Discuss: Which provinces require chemical companies to implement four-zone separation? Are there precise distinctions? Or is it a one-size-fits-all approach, such as not implementing it for existing companies but only for new chemical plants? How do you view the good and bad separation of the four areas? Are there many benefits? Or are there more disadvantages?
Four-zone separation refers to the effective separation and partitioning of administrative office areas, logistics support areas, centralized control areas and production operation areas of hazardous chemicals production and storage enterprises.
According to the "Chemical Enterprise General Plan Transportation Design Code" (GB50489-2009), "Control Room Design Code" (HG/T20508-2014) and other specifications, the four zones are defined as follows: (1) Administrative office area: Administrative office buildings, conference halls, garages, parking lots and other office areas independently set up by enterprises (including subordinate branches and workshops) for production scheduling and operation management. (2) Logistics support area: Canteens, bathrooms, first aid stations, shift dormitories and other living service facilities areas. (3) Centralized control area (central control room): A comprehensive building or place with functions such as factory-wide production operations, process control, safety protection, instrument maintenance, and production information management. (4) Production operation area: An area where production facilities or devices are concentrated to complete the production process. It consists of production facilities or devices, auxiliary production facilities, public engineering facilities, warehousing facilities, transportation facilities, loading and unloading facilities, etc.
