In a Bow-Tie analysis, which component describes the role of preventive and mitigative measures?

• A. Barriers located between hazard and consequences.
• B. Insurance policies.
• C. Employee handbooks.
• D. Emergency drills only.

Answer: (A)

In Bow-Tie analysis, risk is shown as a chain from a hazard to a top event and then to consequences, with barriers placed to block or weaken each link. Preventive measures act as barriers between the hazard and the top event, aiming to stop the event from occurring, while mitigative measures act as barriers between the top event and the consequences, aiming to limit impact if the event happens. The option describing barriers located between hazard and consequences captures the role of both preventive and mitigative measures as the protective controls that sit along the chain from hazard through the top event to the outcomes. The other choices reference specific actions or documents, but they don’t embody the integrated barrier concept that spans the hazard-to-consequences pathway.
