Introduction

Core framework and technical points of the standard

This standard systematically constructs an urban safety risk assessment system covering both natural disasters and accidental disasters for the first time, and innovatively proposes a three-level risk assessment model of point-category-region, which is applicable to sub-provincial cities, prefecture-level administrative regions and municipalities directly under the central government.

Risk Assessment Process Comparison Table

Phase	Core Tasks	Key Technologies	Output Results
Planning and Preparation	Determine the Scope of Assessment/Establish a Working Group	Grid Division Technology	Risk Assessment Plan
Risk Identification	Risk Sources and Potential Events Identification	Event Tree Analysis + Delphi Method	Risk List (including 12 typical risk sources)
Risk Analysis	Possibility and Consequence Quantification	FN curve method + scenario analysis method	Risk level matrix
Risk assessment	Grade determination and regional superposition	Application of ALARP principles	Four-color risk distribution map

Key technology innovation

1. Multi-dimensional risk grading system

A matrix evaluation model of 5-level possibility (Level IV) and 5-level consequence (Extremely serious-low) is established, and the four-color risk levels of red, orange, yellow and blue are output through the risk matrix method.

2. Intelligent identification of typical risk sources

Appendix C provides a list of 47 types of natural disasters and 39 types of accidents and disasters, including:

Urban lifeline facilities (water supply/electricity/gas)
High-rise building complexes
Hazardous chemical storage

3. Dynamic update mechanism

It is required to establish an annual assessment + trigger update mechanism to initiate special assessments when there are planning adjustments, major emergencies, etc.

Implementation Suggestions

1. Information platform construction

It is recommended to use GIS technology to build a risk map to achieve:

Spatial annotation of risk sources
Multi-source data fusion analysis
Intelligent matching of emergency resources

2. Cross-departmental collaborative process

Technology Evolution Analysis

Compared with GB/T 23694-2013 "Risk Management Terminology", this standard has three major breakthroughs:

Urban Specificity: Adding Social Risk (FN Curve) and Urban Operation Interruption indicators
Practical Orientation: Providing 22 Appendix Form Templates
Technology Integration: Introducing the Application Requirements of Natural Disaster Census Results

Typical application scenario: A city identified the compound risks caused by aging of underground pipe networks through this standard, and shortened the response time for rainstorm waterlogging by 40%.
