"Three checks and four determinations" is a process experienced by petrochemical industry before the completion of project construction. "Three inspections and four determinations" officially appeared in the chemical debugging regulations issued by the Ministry of Chemical Industry 1988, and the three inspections and four determinations are the quality assurance of the project; Therefore, it has become an effective means to ensure the success of linkage debugging and trial operation.
Extended data:
Before the trial production of a construction project, it is necessary to organize the engineers and technicians of the design, construction, supervision and construction units to conduct "three inspections and four determinations", formulate a trial production plan, and organize the trial production in strict accordance with the trial production plan and relevant norms and standards. Operators can participate in trial production only after passing the post examination. When the project is accepted, the safety facilities shall be accepted at the same time.
Safety facilities shall be designed, constructed and put into use at the same time as the main project, so as to ensure the use of safe and reliable technologies and equipment, ensure that the construction project is technically reliable, the safety facilities are complete and effective, and the automatic control level can meet the needs of safety production. We must strictly abide by the design specifications, standards and relevant regulations, and entrust units with corresponding qualifications to be responsible for design, construction and supervision.
