Introduction
1. Background and significance of standard formulation
As the core area for the production and storage of hazardous chemicals, the safety risk assessment of chemical parks is directly related to the safety of people's lives and property and social stability. In recent years, with the rapid development of my country's chemical industry, the number and scale of chemical parks have continued to expand, and safety hazards have also increased.
1.1 Background of standard formulation
- Policy drive:The Office of the State Council's Safety Committee and other departments have issued documents many times, requiring the strengthening of safety management in chemical parks.
- Insufficient local practice:Previously, there was a lack of unified standards in various places, and the assessment work was arbitrary and non-standard.
- Technical requirements:Scientific and systematic safety risk assessment methods and technical guidelines are urgently needed.
1.2 Significance of the Standard
GB/T 45233-2025 fills the gap in the national chemical park safety risk assessment standards and provides unified technical specifications and implementation guidelines for all regions. Through scientific risk assessment, the overall risk level of the park can be effectively reduced and the sustainable development of the chemical industry can be guaranteed.
2. Comparative Analysis of Standard Frameworks
| Dimensions | Characteristics of the new standard | Differences from the old standard | Actual impact |
|---|---|---|---|
| Scope of assessment | Comprehensive coverage of the entire life cycle, including site selection, enterprise layout, and public facilities | The old standard only focused on some links | Improve the overall risk management capabilities of the park |
| Assessment methods | Introduce quantitative risk assessment (QRA) and domino effect analysis | The old standard mainly focuses on qualitative assessment | Improve the scientificity and accuracy of risk assessment |
| Implementation cycle | A comprehensive assessment is required at least every three years | The old standard does not have clear cycle regulations | Ensure continuous improvement and dynamic management |
3. Implementation suggestions and practical applications
3.1 Implementation steps
- Data preparation:Collect basic data such as park planning, enterprise information, and accident records.
- Risk identification:Identify hazardous sources and harmful factors, including chemical properties, process risks, etc.
- Unit division:Divide the assessment units according to the characteristics of the park to ensure that all risk areas are covered.
- Method selection:Combining quantitative and qualitative methods, GB/T 37243 and SH/T 3226 are preferred.
- Countermeasures and suggestions: Specific prevention and control measures should be proposed for the discovered risk points, and the implementation effect should be evaluated regularly.
3.2 Implementation tools and technologies
To improve the efficiency and accuracy of risk assessment, the following tools and technologies can be used: Quantitative risk assessment software (such as PHAST, JSA), Geographic Information System (GIS), Domino effect simulation model, etc.
3.3 Common problems and solutions in implementation
- Insufficient data: It is recommended to strengthen the informatization construction of the park and establish a unified data sharing platform.
- Lack of professional personnel: It is recommended to introduce a third-party technical service agency, or organize internal training to improve capabilities.
- Long evaluation cycle: A phased evaluation method can be adopted to gradually advance risk management work.
4. Key points of the specification in the charts
Case analysis: Quantitative risk assessment results of a chemical park
Assessment object:A large-scale comprehensive chemical park, involving the production, storage and transportation of hazardous chemicals.
Assessment method:The quantitative risk assessment process specified in GB/T 37243-2019 is adopted, combined with domino effect analysis.
