Bowtie Suite

Barrier failure or weakening is often a causal factor in accidents and incidents. State Supervision of Mines uses bowties to identify the weak barriers by analyzing different incidents.

The insights from the bowties are helpful in assisting the gas network operators with their safety programs.

Some people were a bit skeptical, until we started making bowties in BowTieXP. They could actually see the progression of the threat, through the top event, ultimately ending up with the undesirable consequence, and what controls are in place to prevent this. If we had to do exactly the same in a text document, it would have to be a very large document to cover the same information. The bowtie format is very effective.
