=== Control and Recovery Barriers ===
Barriers in the Bowtie bowtie appear on both sides of the Top Eventtop event. Barriers interrupt the scenario so that the threats do not result in a Loss loss of Control control (the Top Eventtop event) or do not escalate into an actual impact (the consequences)
There are different types of Barriers, which are mainly a combination of human behaviour behavior and/or hardware/technology. Once the Barriers are identified, you have a basic understanding about how risks are managed. You can build on this basic barrier structure further to deepen you understanding of where the weaknesses are. Barriers can be extended besides Barrier types to include for instance Barrier effectiveness. This lets you assess how well a Barrier performs. After that you can look at the activities you have to implement and maintain you Barriers. This essentially means mapping you Safety Management System on the Barriers. Also determining who is responsible for a Barrier and assessing the criticality of a Barrier are things you can do to increase your understanding of the Barriers.
