What are some common issues with barrier / risk control systems, and bow ties? Extracts: · Multiple barrier definitions exist, one is “Safety barriers are physical and/or nonphysical means planned to prevent, control, or mitigate undesired events or accidents” · “This definition allows for both hardware barriers (e.g., Emergency Shutdown Systems) and for non-physical barriers (e.g., inspection… Continue reading Risk barrier and bow tie quality issues

Visualizing what’s missing: Using deep learning and Bow-Tie diagrams to identify and visualize missing leading indicators in industrial construction
This study, among a few other things, compared 633 incidents against >9 inspection reports with similar contexts to understand the overlap. Data was from a Canadian construction project over 3 years. E.g. They used multi-methods, including natural language processing, text mining, bow ties and more to evaluate if field inspections are looking at the same… Continue reading Visualizing what’s missing: Using deep learning and Bow-Tie diagrams to identify and visualize missing leading indicators in industrial construction
