Major accident prevention frameworks traditionally focus on technical and organisational safety measures, while resilience aspects such as adaptive capacity, learning and recovery are not systematically assessed. The COVID-19 pandemic and other disruptive events have highlighted the importance of organisational resilience for maintaining safety under abnormal and rapidly changing conditions. However, resilience concepts are rarely operationalised within safety management systems for major accident hazards. The RASEM project addresses this gap by integrating resilience concepts into major accident risk assessment and safety management, supporting more robust prevention and response capabilities.
