QRA ALARP Considerations in TSFs Including Climate Change and Extreme Events Consideration

Franco Oboni, Corporate Risk Assessment Consultant, explains how quantitative risk assessment (QRA) and the As Low As Reasonably Practicable (ALARP) principle should be applied to tailings storage facilities (TSFs), particularly in the context of climate change and extreme events.

He emphasizes that ALARP is not a fixed point but a decision-making process that balances risk reduction with cost, guided by technical analysis and stakeholder input—including public expectations.
