On the basis for self-control design

Are there any specific regulations requiring this?

“Notice of the State Administration of Work Safety and the Ministry of Housing and Urban-Rural Development on Further Strengthening the Safety Design Management for Hazardous Chemicals Construction Projects” (An Jian Zong Guan San [2013] No. 76). II. Effectively implement the responsibilities for safety management of construction projects. (III) The project owner shall entrust a design unit that possesses the required qualification level to carry out the engineering design for the project, and shall apply legally for a safety review of the project as well as handle the relevant procedures. For construction projects subject to engineering supervision, the supervision of safe construction quality should also be entrusted. The project owner should, in the design contract for the construction project, actively request the design firm to conduct a Hazard and Operability (HAZOP) study, and assign personnel with experience in production operations to participate in this review as well as to examine the HAZOP report. For construction projects involving \"two key aspects, one major aspect\" and first-time industrial design, a HAZOP analysis must be conducted during the basic design phase. III. Strengthening the management of the safety design process (9) Design agencies should enhance the analysis of safety risks associated with construction projects, and actively employ methods such as HAZOP analysis for internal safety design reviews.

Normally, it should be the process engineering team that submits a request to the control engineering team; the control engineering team then carries out the design based on that request. After the preliminary design is completed, a HAZOP analysis agency conducts a HAZOP analysis of the PID diagrams in the preliminary design documents, proposes corrective measures, and modifies the design documents accordingly
