Research and Application of the Safety Management Model “Network‐Wall‐Field” Based on the Concept of System Safety

Traditional safety management focuses on the addition of safety protection devices and strict control of personnel behaviour to safeguard the safety of individuals and equipment. However, the concept of system safety emphasizes a comprehensive analysis of multi‐dimensional factors such as social, cultural and intrinsic safety levels, based on the principles of accident causation. This approach aims to eliminate or reduce risks in production systems from the source. As a result, the theory and methods of safety management have evolved from a purely technical level to a broader focus on system management. Building upon a review of accident causation and system safety theory, this paper aims to analyse the various elements contributing to accidents. By utilizing the framework of system safety theory, a comprehensive set of institutional systems, risk prevention and control measures, and a culture of safety coordination are established. This is achieved through the implementation of a PDCA (Plan‐Do‐Check‐Act) efficient operational safety management mechanism. Furthermore, an optimized ‘Network–Wall–Field’ safety management model is developed. Detailed case studies are shared to showcase the results of this approach.
