Risk Management Using Safety Barriers (Bowtie Method) C108

Effective risk management requires a thorough understanding of the accident pathways linking threats to potentially catastrophic consequences and the measures implemented to prevent this happening. Bowtie diagrams provide a simple visualization of the relationships and the barriers preventing the catastrophic consequences. Bowtie diagrams are easy to interpret unlike the complex and/or numerical results from other risk assessment methods (e.g. PHA, QRA, LOPA) in a way that is easier for non-experts, workforce, engineers and managers to understand.

This course progressively builds day-by-day. Day 1 introduces the Bowtie Method and provides awareness of its uses by working through the steps involved to identify process safety layers. Day 2 builds practical experience and confidence with hands-on construction of barrier diagrams both on paper and using the Bowtie Master Software. The second day also covers Barrier effectiveness, Process Safety Performance Indicators (PSPIs), the use of barrier diagrams in Incident Investigations, incorporating human factors and an introduction to Layer of Protection Analysis (LOPA) Attendees also receive a free trial of Bowtie Master.

In 2018 the CCPS published the concept book "Bow Tie Risk Management" together with the UK's Energy Institute. The book provides clear guidelines on the terminology to be used in bowties and the approaches to be followed in developing and subsequently maintaining the resultant bowties. ABS Group was actively involved on the committee writing the book and this course is fully consistent with all aspects of the book.
