Abstract:

AQ/T 3033—2022 Guidelines for the safety design management of chemical construction projects is an important basis for the safety design management of chemical construction projects, and it is also an important basis for government departments to supervise the safety design process of chemical construction projects. The new edition(2022 edition) pays more attention to the integrity management of safety design, and highlights the concept of inherently safe design based on risks. It runs through the whole process of preliminary design, basic engineering design, detailed engineering design, design coordination of construction installation and commissioning, and design return visit after the completion of the project. It guides design units to further improve the construction of safety design management system for chemical construction projects from the traditional standard-based design mode to the risk-based design mode. Strengthening the safety design management of chemical process is a method for preventing and controlling major industrial accidents, and an important basic work for eliminating potential safety hazards, preventing accidents, and building a long-term mechanism for safe production. In the design process of the process and its facilities, in accordance with the principle of inherently safe design, priority is given to reducing project safety risks by carrying out process optimization or changing process routes, strengthening the application of fine chemical reaction safety risk assessment results, and improving risk management and control measures, in order to fundamentally prevent the occurrence of unexpected events.

Key words: chemical construction projects, safety design management, inherently safe design, fine chemical industry, reactive safety, risk assessment, hazard analysis, process hazard class
