ASW #1: COVID-19 & Safety: A Bow-Tie Risk Assessment Approach

Today’s theme is “maintaining airport safety through COVID-19”. Obviously, this can be a big topic. There are thousands of ways COVID-19 has impacted our daily lives - some large and some subtle. So, in thinking about this topic, I wanted to create a structure we could use to analyse the virus’s impact.

And I landed on the Bow-Tie model. Check it out.

Bow-Tie Risk Assessment Series

A long time ago, I was deep into the bow-tie risk assessment methodology and over the years, I have never really left it. These posts were the basis of some great work I did a couple of years ago working with BHP Billiton which I will blog about in the near future.

BTIII: Assessing Uncertainty

I can't lie to you. I have been turning myself inside out trying to get a handle on risk evaluation in the aviation safety sphere for close to five years now and I still don't feel any closer to an answer. And I say "an" answer and not "the" answer. Since you are always assessing risk in terms of your objectives, there can and will be multiple approaches to assessing the risk of the same scenario depending on whether you are considering your safety, financial or legal objectives.

BTII: Control-freak*

As a follow-on to my first post on the Bow-Tie risk assessment method, I thought I'd concentrate on controls (or barriers or whatever else you would like to call them). This is, after all, where all the action happens. Risk controls are how we spend most of our time - they are the practical aspect of managing risk.

BTI: Dressing up for Risk Assessments

I've been doing a lot of pondering on the Bow-Tie method of risk assessment for a project at work. Bow-Tie is a tool used by many, especially in the oil & gas industry, to create a picture of risk surrounding a central event. It's got a few positives and a few negatives but these can be overcome if you understand the limitations of the model being used.
