Which risk barriers are the most important? This question can be answered with barrier criticality. In this article we discuss why & how to approach barrier criticality as well as some challenges.

Practical applications of bowtie
It can be a challenge to know what to use bowties for. In this webinar we show different practical applications of bowties. From risk communication to barrier monitoring and decision support.
5 reasons why analysing barrier failures is better than 5-why
I hope you'll forgive me, but I don't really like 5-why. It's a decent methodology, but I think there are better options. Instead, we can use barrier-based incident analysis methods. Why is this better? Well, here are 5 reasons why I think analysing barrier failures is better than 5-why.
The barrier maturity model
Many organisations have adopted the idea of barrier management in safety. Many are also searching for ways to take a next step. With the barrier maturity model you can determine where your organisation currently is and see which steps can be taken to mature to a higher level of barrier management.
An alternative to the hierarchy of control
The hierarchy of control is often used as a brainstorming tool to come up with effective controls (aka, barriers). It's good because it favours proactive interventions like eliminating a source of fuel over reactive interventions like putting out a fire. However sometimes it is misused as a formal classification tool.
Barrier states
A barrier can have different states in an incident, mostly divided into four types: 1) Missing barriers 2) Failed barriers 3) Inadequate barriers and 4) Effective barriers. There are considerable differences in interpretation of these states, and when one or the other should be used. Here I'd like to give
