| Abstract: | This study aims to highlight the importance of evaluating explosive atmosphere (ATEX) risks and to propose a novel, more accurate and comprehensive risk assessment method compared to traditional existing approaches. To address the limitations of traditional ATEX risk assessment methods, this study introduces a new approach based on three key parameters: occurrence, detection, and severity. These factors are combined using a weighted sum (WS) formula to calculate a modified risk priority number (RPN), enhanced by the analytic hierarchy process. This hybrid methodology provides a more precise and reliable assessment of ATEX risks. Moreover, the findings of the proposed WS-RPN method (and its ATEX-specific version, WS-RATEX) demonstrate superior accuracy and lower duplication rates compared to conventional risk assessment techniques. A sensitivity analysis confirms the robustness, stability, and reliability of this approach, making it a valuable tool for quantifying ATEX risks. It is evident to say that WS-RPN represents a significant advancement in ATEX risk assessments. By integrating a refined calculation model, and factoring in occurrence, detection, and severity, the latter ensures a more systematic and reliable evaluation. Thus, with improved risk prioritization, this approach not only enhances industrial installations' safety but also serves as a more effective alternative to traditional assessment methods.
