Do Bow Ties Have a Place in Alarm Management?

Recording Date: April 2020

Bow Tie Diagrams, which have becoming increasingly popular over the last 20 years, provide a powerful and easy-to-understand way to visualize how a company controls risks to prevent major accident hazards. They illustrate the relationships between hazards, causes, potential consequences, the barriers in place to prevent the event or mitigate the results, and the degradation factors that might cause a barrier to fail. This webinar will provide an overview of the Bow Tie methodology and how it might be applied to alarm management. Content will be drawn from the new CCPS book “Bow Ties in Risk Management: A Concept Book for Process Safety” and other references. Specific examples include the Buncefield UK explosion / fire and the Gas Well Blowout and Fire at the Pryor Trust Well.
