The Bow tie method is a risk evaluation method that can be used to analyse and demonstrate causal relationships in high risk scenarios.
A 'bowtie' is a diagram that visualizes the risk you are dealing with in just one, easy to understand the picture.
ECO Safetech can manage Bow-Tie Analysis.
Eco Safetech is following a simple process of Bow Tie Analysis where new or enhanced controls may be Worthwhile. It is a core part of risk treatment planning, particularly where there is a high level of risk or where control effectiveness is assessed as low. A bow tie is a graphical depiction of pathways from the causes of an event or risk to its consequences in a simple qualitative cause-consequence diagram. It is a simplified combination of a fault tree that analyses the cause of an event or risk, the left-hand side of the diagram, and an event tree that analyses the consequences, the right- hand side. It is represented as a bow tie, where the knot of the bow tie is the point where the fault tree paths converge, and the event tree spans out. While bow tie diagrams can be constructed from fault and event trees, they are more often drawn directly from a brainstorming session, providing a fruitful basis for a group exploration of controls. Bow tie analysis is a risk management technique used to visualize and assess potential hazards and their associated consequences. It involves creating a diagram that looks like a bow tie, with the hazard or event in the center and the potential consequences branching out on either side. The bow tie analysis is a useful tool for identifying potential risks and developing strategies to mitigate them. By identifying the causes and consequences of a hazard, organizations can develop plans to prevent the hazard from occurring, minimize its impact if it does occur, and recover from its effects more quickly. The bow tie analysis can be applied to a wide range of industries and scenarios, including manufacturing, transportation, healthcare, and emergency management. The bow tie analysis can be a helpful tool for communicating risk information to stakeholders and decision-makers. The visual nature of the diagram makes it easy to understand the potential hazards and consequences of a particular event, and can facilitate discussions around risk management strategies and priorities.
Bow-Tie Threats Analysis
As with the threats, people tend to focus on generic categories instead of describing specific events. Try not to focus on injury/ fatality, asset damage, environmental damage, reputation damage or financial damage. Those are broader categories of damage rather than specific consequence event descriptions. Try to describe events like ‘car roll over’, ‘oil spill into sea’ or ‘toxic cloud forms. Besides containing more specific information, you’re also helping yourself to think more specifically when coming up with barriers. Think how you want to prevent ‘environmental damage’ versus ‘oil spill into sea’. The second is an actual scenario which makes it much easier to come up with specific barriers.
Building Bow Tie
Bow tie analysis is a simple process for identifying where new or enhanced controls may be worthwhile. It is a core part of risk treatment planning, particularly where there is a high level of risk or where control effectiveness is assessed as low. Software helps but don’t get hang up on it!
