Amidst the escalating complexity of process operations, ensuring effective process safety management (PSM) is crucial to prevent major accidents. However, current PSM practices often lack the integration of evidence resources, leading to a research-to-practice gap and hindering PSM's development. To address these challenges, this study proposes evidence-based process safety management (EBPSM), which systematically integrates various evidence types such as incident reports, hazard assessment, safety audits, and scientific literature, to optimize PSM and enhance professional expertise. Firstly, the study reviews PSM development, emphasizing its shortcomings concerning safety information. Subsequently, the EBPSM approach is introduced, highlighting its necessity and key determinants. A comprehensive framework for EBPSM is presented, detailing each stage of its operational processes. To demonstrate the extended application of EBPSM, the framework is employed in liquefied natural gas (LNG) maritime safety management. Finally, the study concludes by discussing limitations and suggesting future directions for EBPSM. By emphasizing the systematic integration of evidence resources and the necessity of applying EBPSM systematically, this study aims to equip process safety practitioners with a well-informed understanding of the evidence-based approach and its potential to enhance process safety outcomes in future PSM implementations. Moreover, embracing the EBPSM approach may enable industries to proactively mitigate risks and foster a safer and more resilient working environment.
