Core Viewpoint - The Ministry of Emergency Management has developed a draft assessment method for aging chemical facilities to systematically identify, evaluate, and manage aging risks, aiming to establish a long-term safety risk control mechanism in the chemical industry [1][4]. Group 1: Assessment Method Overview - The assessment method is applicable to chemical enterprises involved in the production and use of hazardous chemicals, with other chemical companies and hazardous chemical storage enterprises encouraged to refer to it [2]. - The method highlights that many chemical facilities built in the 1980s are now over 30 to 40 years old, facing issues such as low design standards, corrosion, and reduced safety capabilities, leading to concentrated exposure to safety risks [2][3]. Group 2: Factors Influencing Aging - The assessment identifies ten key factors affecting the aging of chemical facilities, including service time of critical equipment, unplanned downtime, equipment defects, aging mechanisms, integrity management, inspection strategies, energy efficiency, corrosion protection, operational stability, and control equipment aging [2]. Group 3: Current Situation and Need for Standardization - Many old facilities have undergone multiple renovations, resulting in discrepancies between nominal age and actual usage time. For instance, a survey of 20 facilities over 20 years old revealed that 63.57% of pressure vessels were over 20 years old, with varying safety levels [3]. - The lack of a standardized aging management mechanism necessitates the establishment of a comprehensive evaluation technique to facilitate the management of aging facilities and provide a compliance exit for those that exceed their design lifespan but remain safe to operate [3]. Group 4: Implementation and Feedback - The establishment of this standard is expected to promote a long-term management mechanism for aging chemical facilities, addressing safety concerns systematically and continuously [4]. - Chemical enterprises are advised to develop and implement aging assessment plans based on their specific circumstances, with a suggested transition period of six months [5]. - The deadline for public feedback on the draft assessment method is set for August 5, 2025 [6].
