Uncertainties and their treatment in the quantitative risk assessment of domino effects
Classification and review
Domino accidents are typical low-frequency and high-consequence events in chemical process industries. Applying quantitative risk assessment (QRA) in domino accident assessment is challenging due to the uncertainties in the escalation process. Meanwhile, the outcomes of QRA are s
...
Dynamic-risk-informed safety barrier management
An application to cost-effective barrier optimization based on data from multiple sources
An integrated approach for performance assessment and management of safety barriers in a systemic manner is needed concerning the prevention and mitigation of major accidents in chemical process industries. Particularly, the effects of safety barriers on system risk reduction sho
