== Consequences ==
'Consequences' are the result from the top event. There can be more than one consequence for every top event. As with the threats, people tend to focus on generic categories instead of describing specific events. Try not to focus on injury/ fatality, asset damage, environmental damage, reputation damage or financial damage. Those are broader categories of damage rather than specific consequence event descriptions. Try to describe events like
“Car roll over”, “Oil spill into sea” or “Toxic cloud forms”. Besides containing more specific information, you’re also helping yourself to think more specifically when coming up with Barriers. Think how you want to prevent “Environmental damage” versus “Oil spill into sea”. The second is an actual scenario which makes it much easier to come up with specific Barriers.
== The picture so far ==
At this stage we have a clear understanding of the risk and what needs to be controlled. The
Hazard, Top Event, Threats and Consequences give us an overview about everything we don’t want around a certain Hazard. Every line through the Bowtie represents a different potential incident. Besides containing incident scenarios that might already have occurred, part of the strength of the Bowtie is that there is also room for scenarios which have not occurred yet. This makes it a very proactive approach.
== Barriers: controlling unwanted scenarios ==
Now that we have the unwanted scenarios, it’s time to look at how to control these scenarios as an
organisation. This is done using Barriers.
