Major hazard sources of hazardous chemicals are characterized by concentrated energy and high safety risks, and accidents can easily lead to mass casualties. This standard integrates lessons learned from major chemical industry accidents both domestically and internationally, along with relevant requirements from "Technical Requirements for Acceptance of Safety Monitoring and Early Warning Systems in Flammable and Explosive Storage Areas" (GB 17681-1999), "General Technical Specification for Safety Monitoring of Major Hazard Sources of Hazardous Chemicals" (AQ 3035-2010), and "Specification for the Setting of On-site Safety Monitoring Equipment for Major Hazard Sources of Hazardous Chemicals" (AQ 3036-2010). It standardizes the definition, connotation, and extension of safety monitoring systems for major hazard sources of hazardous chemicals, and clearly stipulates the relevant requirements for system design, construction, quality acceptance, operation and maintenance, and alarm management.

The release and implementation of this standard will further improve the risk control standard system for hazardous chemicals, providing important technical support for effectively managing major safety risks. The Ministry of Emergency Management will subsequently strengthen its promotion and implementation, urging relevant entities to strictly adhere to the standards to ensure their requirements are fully implemented.
