Bowties can be linked to the following safety studies:

    • HAZOP (Hazard and operability study) – Bowties are not a hazard identification method. Instead, they further develop specific major accident events identified by hazard identification methods such as a HAZOP study
    • SIL (Safety integrity level) determinations – Barriers identified in a SIL study for a process facility would normally appear in a bowtie analysis as main pathway barrier
  • Integrating bowties into Safety Case and ALARP (as low as reasonably practicable) demonstrations – bowties provide a qualitative tool to assist in ALARP justifications
  • Operationalising bowtie diagrams (e.g., permitted operations based on barrier status)
  • Used for barrier-based incident investigations
  • Integration with risk register and other risk tools for communicating risk
  • Bowtie diagrams can be used to support real time dashboards (i.e barrier status)
  • Used as part of verification programs and barrier health reviews
