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

Safe AF ep #4: Relationship between fatal and non-fatal accidents based on 23k accidents
Is there a connection between fatal and non-fatal accidents, or is it a fallacy to focus on the minor potential events with the hope of managing the major events? Today’s study explores these relationships based on 23k reported serious accidents in the Netherlands. Ref: Bellamy, L. J. (2015). Exploring the relationship between major hazard, fatal… Continue reading Safe AF ep #4: Relationship between fatal and non-fatal accidents based on 23k accidents
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
