Course overview

What is Barrier Modelling?

Barrier modelling is a visual way of presenting the possible causes that could lead to a hazard developing into an undesirable event. Barrier modelling presents the possible effects of this happening and the barriers that either reduce the likelihood of the event occurring, or reduce the impact of the event should it happen.

Course Overview

This course is designed to provide delegates with an overview of barrier modelling techniques and how they can be used to classify occurrences. Reference is made to ICAO Annex 13 (Amendment 17) which refers to the classification of serious incidents and how remaining barriers between the event and an undesirable outcome were left intact need to be considered.

Delegates will explore a series of techniques that can be applied to create barrier models together with best practice guidelines on how to structure and maintain a barrier model.

Who should attend?

This course is suitable for anyone who requires a generic overview of barrier modelling in the aviation context.

  • Introduction to Barrier Models
