About Bow-Tie analysis

Bow-tie analysis maps a single top event to the threats that can cause it and the consequences that can follow, then sets out the preventive and mitigative barriers on each side. Its visual, barrier-centred format makes major-accident risk easy to communicate to operations and management, and straightforward to audit for barrier health.

The facilitators listed here build bow-ties to underpin safety cases, to communicate the outcomes of HAZOP and LOPA studies, or to support barrier-based management of major-accident hazards.
