Core Viewpoint - The Ministry of Emergency Management has released a mandatory industry standard titled "Guidelines for the Design of Safety Facilities in Hazardous Chemical Construction Projects" (AQ 3066—2025), which will take effect on July 1, 2026. This standard aims to enhance safety risk prevention and control in hazardous chemical projects by addressing design flaws and emphasizing inherent safety design principles [1]. Group 1 - The guidelines focus on fundamental and critical work to prevent major safety risks from the source and implement inherent safety [1]. - The standard incorporates lessons learned from recent accidents, addressing design deficiencies and "inherent shortcomings" [1]. - It emphasizes process hazard analysis and sets strict qualification requirements for design units [1]. Group 2 - The guidelines specify requirements for process safety reliability verification, safety risk assessment of reactions, and external safety protection distances [1]. - It strengthens safety control measures related to "two key points and one major" and under abnormal working conditions [1]. - Detailed requirements for safety facilities include automation control, process systems, layout, equipment and piping, electrical instruments, and emergency response [1]. Group 3 - The guidelines clarify responsibilities regarding who should design safety facilities and how to approach the design process [1]. - They address what should be included in the specialized documentation and how it should be written [1]. - The implementation of these guidelines is expected to significantly improve the safety risk prevention and control level in hazardous chemical construction projects [1].
