Abstract：Due to the characteristics of flammable and explosive materials, complex and changeable processes, and lengthy risk chains, the hazardous chemicals industry has become a top priority in work safety supervision. The dual prevention system of work safety risk classification management and control and hidden danger investigation and management (hereinafter referred to as the “dual-control system”), as the core means to prevent and resolve safety risks of hazardous chemicals, its construction quality directly determines the intrinsic safety level of the industry. Based on the latest requirements of GB45673-2025 "General Specifications for Work Safety Standardization of Hazardous Chemical Enterprises" and combined with the practice of build-ing the dual-control system in hazardous chemical enterprises in various regions, this paper systematically analyzes the core connotation and operation logic of the dual-control system, and deeply discusses the prominent problems existing in the current construction process, such as cognitive deviations, mechanism disconnection, and insufficient technical support. It proposes op-timization paths from four dimensions: responsibility consolidation, process optimization, intelligent empowerment, and cultural cultivation, providing theoretical reference and practical guidance for promoting the transformation of hazardous chemical enter-prises from “passive response” to “active prevention and control”.
