Abstract Connecting RAGAGEP within Hazard Studies to Enhance Safety and Reliability. Process Hazard Analyses (PHA) are integral to hazard identification and risk assessment. Their structured and multidisciplinary approaches allow for the design and evaluation of safety barriers tailored to prevent and mitigate major accident hazards in both new and existing facilities. However, the effectiveness of these barriers relies heavily on adherence to Recognized and Generally Accepted Engineering Practices (RAGAGEP), which are foundational for reducing incidents in safety‐critical systems. RAGAGEP establishes consistent engineering and administrative controls based on widely accepted industry standards. By applying RAGAGEP in PHA studies, companies achieve more robust and reliable safety measures that capture the complexity of potential major accidents and address real operational scenarios, not only theoretical approaches. This adherence not only aligns with regulatory expectations but also promotes the ALARP principle, ensuring that safety risks are minimized. The review of safety barriers under RAGAGEP‐guided PHA scenarios helps identify overlooked hazards, chronic operational issues, and changes made post‐design, providing a comprehensive risk assessment. Ultimately, this approach builds resilience within operations, minimizing the uncertainty of safety barrier effectiveness and offering greater protection to personnel, the environment, and the facility's operational integrity.
