To enhance gas safety management, this study establishes a provincial-level gas safety risk quantitative evaluation system. The research content includes setting the evaluation objects, establishing quantitative evaluation rules and calculation methods, formulating risk and hidden danger classification and grading standards, developing evaluation indicators, building a safety risk evaluation working mechanism, working an information support system for automatically identifying and warning of weak areas, weak enterprises, weak links, and weak users with higher safety risks. It forms a regulatory closed- loop in conjunction with offline rectification to establish a complete provincial-level gas safety risk quantitative evaluation system.
