What is the meaning of "three inspections and four determinations" in chemical enterprises?

Three inspections and four determinations in chemical enterprises refer to the management mode of "three simultaneities", "one place and two parties" and "four essentials". Details are as follows:

(1) "Three simultaneities" includes: design, construction and acceptance are carried out simultaneously; Commissioning, operation and maintenance shall be carried out simultaneously; Safety assessment, environmental impact assessment and occupational health assessment should be carried out simultaneously.

(2) "One place and two parties" means that the construction unit and the user unit are the same unit, both builders and operators, which can reduce the transformation problems and facilitate implementation.

(3) "Four Musts" include: indispensable technology, indispensable equipment, indispensable technology and indispensable management, that is, after the construction is completed, there must be a system to strictly verify whether each technology, equipment, process and management is really in place. These are all important measures to ensure the safety and stability of chemical enterprises.

In addition, there are "five prohibitions", including the prohibition of unqualified and unapproved production and unqualified products, the prohibition of adding modification technology and equipment during the shutdown period, the prohibition of connecting wires without permission, the prohibition of smoking in the production area and the prohibition of dumping production waste at will to ensure the safety production, environmental protection and compliance of chemical enterprises.

Only in this way can we strengthen risk pre-control, reduce accident risk, standardize management and effectively maintain social harmony and stability. ?
