Risk barrier and bow tie quality issues

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

Preventing fatal accidents in construction through the management of barriers

This paper explored a (close-to) real-time safety performance indicator for barriers (sometimes called ‘controls’, although other typologies place barriers and safeguards under the broader category of ‘barriers’). The author developed and tested an indicator for the availability of barriers against fatal accidents during construction work. I’ve skipped a lot – but it’s open access, so… Continue reading Preventing fatal accidents in construction through the management of barriers

Exploring the relationship between major hazard, fatal and non-fatal accidents through outcomes and causes

This study from Linda Bellamy explored whether there is a relationship between major hazards, and fatal and non-fatal accidents. Analysis of 23k Dutch serious reportable accidents was analysed via the StoryBuilder software (largely based around bowties). [NB. As always, there’s certain limitations and nuances with relying on reported accidents, particularly around how they’re reported, how… Continue reading Exploring the relationship between major hazard, fatal and non-fatal accidents through outcomes and causes
