The chemical park safety risk assessment proposes scientific, reasonable and feasible regional safety risk control measures and regional emergency rescue system construction The activities of summarizing the evaluation results are necessary to reduce the risk level of new and existing chemical parks. The Office of the State Council's Guiding Opinions on Further Strengthening Safety Management in Chemical Industrial Parks (No. 37 of the Office of the State Council's Safety Committee [2012]) first proposed that chemical industrial parks should The State Council's Safety Committee, the Ministry of Emergency Management, and the Ministry of Industry and Information Technology issued a series of policies and measures to For example, the National Three-Year Action Plan for Special Rectification of Work Safety (Safety Committee [2020] No. 3), the Guiding Opinions" (Ministry of Industry and Information Technology [2015] No. 433), "Chemical Park Construction Standards and Certification Management Measures (Trial)" (Ministry of Industry and Information Technology [2021] 220) and the "Guidelines for the Investigation and Governance of Safety Risks in Chemical Parks" (Emergency [2023] No. 123), etc., provide guidance on the safety risk assessment of chemical parks. Make specific requirements. In order to implement the national policy requirements and standardize the safety risk assessment work of chemical parks, Jiangsu, Shaanxi, Ningxia, Sichuan, Henan, 10 provinces and autonomous regions, including Shandong, Shanxi, Hunan, Guangdong and Xinjiang, have formulated local standard documents. These local standard documents guide third-party units However, the safety risk assessment of chemical parks has not been carried out in a standardized manner at the national level. There is no unified standard. It is not clear how to carry out risk assessment in chemical parks in various regions. The assessment procedures, content, methods and reporting requirements are unclear. Indeed, the quality of the evaluation by the third-party unit cannot be judged. This has resulted in the chemical park safety risk assessment work failing to achieve its intended purpose. The work has no practical results and the country's policies are difficult to implement. The Guidelines for Risk Assessment of Chemical Industrial Parks stipulates the overall requirements, assessment procedures, assessment contents and methods of safety risk assessment of chemical industrial parks. The evaluation report fills the gap of the lack of safety risk assessment standards at the national level and plays an important role in the risk assessment work of chemical parks in various places. guiding significance. Guidelines for Safety Risk Assessment in Chemical Industrial Parks

1 Scope

GB/T 45233-2025 gives the Chinese guidelines for comprehensive safety risk assessment of a chemical industry park. China concentrates its chemical industry into parks, and the assessments that had been done plant by plant missed exactly what the Tianjin and Xiangshui disasters demonstrated: the risk of a park is not the sum of the risks of its plants, because escalation between installations, shared infrastructure, the storage and movement of material between them and the surrounding population are properties of the park as a whole. The standard sets the assessment content and procedure, the collection of the information required, the identification of the hazard installations and of the major accident scenarios, the analysis of domino and escalation effects between plants, the assessment of the individual and societal risk to the surrounding population, the evaluation of the park's layout, separation distances, emergency infrastructure and response capability, the grading of the park's risk level and the risk control measures and improvement plan that follow. It takes effect on 1 May 2025.

This document provides the general principles, assessment procedures, assessment content and methods, and assessment report of chemical park safety risk assessment. guide. This document is applicable to safety risk assessment of chemical parks.
