Bow tie analysis is a risk assessment technique that uses a graphical representation to identify and assess the risks associated with a particular activity or process.
Origin of Bowtie Analysis
The origin of Bowtie analysis is unclear, but it is believed to have originated in the 1970s. The first known use of the bowtie diagram was in a lecture on hazard analysis given at the University of Queensland, Australia, in 1979. The diagram was developed by Dr. Trevor Kletz, a safety engineer who worked for Imperial Chemical Industries (ICI). Kletz used the diagram to help engineers identify and assess risks in chemical plants.
In the 1990s, the bowtie diagram was adopted by the oil and gas industry. The industry found that the diagram was a useful tool for identifying and assessing risks in offshore drilling operations. The diagram has since been adopted by other industries, including the nuclear, chemical, and manufacturing industries.
The bow tie diagram consists of three main parts:
- The hazard: This is the event or condition that could cause harm.
- The top event: This is the most serious outcome that could result from the hazard.
- The barriers: These are the controls that are in place to prevent the hazard from occurring or to mitigate the consequences of the top event.
Bow tie analysis is a useful tool for identifying and assessing risks in a variety of settings, including industrial, commercial, and healthcare settings. It can be used to identify potential hazards, assess the likelihood and severity of risks, and develop and implement risk control measures.
Here are the steps involved in bow tie analysis:
- Identify the top event. The top event is the event that could potentially occur if the risk is not managed. It is important to be as specific as possible when identifying the top event. For example, instead of saying “an accident,” the top event could be “a fire.”
- Identify the bow tie. The bow tie represents the barriers or controls that can prevent the top event from occurring. These barriers can be physical, procedural, or human. For example, a physical barrier could be a guardrail, a procedural barrier could be a lockout/tagout procedure, and a human barrier could be a trained employee.
- Identify the consequences. The consequences are the negative outcomes that could result from the top event. It is important to be as specific as possible when identifying the consequences. For example, instead of saying “damage,” the consequences could be “a fire that causes $1 million in damage.”
- Assess the likelihood and severity of the risks. Once the top event, the bow tie, and the consequences have been identified, it is important to assess the likelihood and severity of the risks. This can be done by considering factors such as the frequency of the event, the severity of the consequences, and the effectiveness of the barriers.
- Develop and implement risk control measures. Once the risks have been assessed, it is important to develop and implement risk control measures. These measures should be designed to reduce the likelihood and severity of the risks.
Bow tie analysis is a valuable tool for identifying and assessing risks. It can be used to improve safety, reduce costs, and protect assets.
