BOW TIE Analysis: Visual tool that depicts pathways between hazards, threats, consequences, and controls. Shows both preventive and mitigative measures in a single diagram.

A “bowtie analysis” is a visual risk assessment method that uses a diagram shaped like a bowtie to identify potential hazards, their causes (threats), the consequences that could occur, and the control measures (barriers) in place to prevent or mitigate those consequences, essentially providing a clear picture of how different factors interact in a risk scenario; it’s often used in high-risk industries like manufacturing and oil & gas to systematically analyze potential accidents and their management strategies.

Key points about bowtie analysis:

Visual representation:

The “bowtie” diagram clearly separates the “top event” (the unwanted incident) into the causes (left side of the bowtie) and the potential consequences (right side), with control measures placed in between.

Barrier identification:

The main focus is on identifying and evaluating the effectiveness of existing safety barriers (controls) that can prevent or mitigate the severity of an incident.

Key points about scenario analysis in safety management:

Forward-looking approach: Unlike traditional risk assessments that focus on past incidents, scenario analysis looks ahead to anticipate potential future events.
“What-if” analysis: The core principle is to consider various “what if” scenarios to identify potential hazards that might not be readily apparent under normal operations.
Multiple scenarios: Typically, a range of scenarios are considered, including best-case, worst-case, and most likely scenarios to get a comprehensive view of potential risks.
Qualitative and quantitative elements: Scenario analysis can involve both qualitative assessments (e.g., describing the potential impacts of an event) and quantitative analysis (e.g., estimating the probability of occurrence and potential severity).

Example scenarios in safety management:

Industrial setting: What if a critical piece of machinery suddenly malfunctions during operation?
Chemical plant: What if a chemical leak occurs due to a pipe failure?
Construction site: What if a heavy object falls from a high elevation during lifting operations?
