The Bowtie method is a risk assessment technique that can be used to analyse and communicate how major accident scenarios develop. The method takes its name from the shape of the diagram that is created, which looks like a man’s bowtie.

The Bowtie method has several goals:

⦿ Provide a structure to systematically analyse a hazard.

⦿ Help make a decision whether the current level of control is sufficient (or, for those who are familiar with the concept, are we ALARP?).

⦿ Help identify where and how investing resources would have the greatest impact.

⦿ Making risk communication as effective as possible.

The training will enable delegates, particularly those not skilled in the area of risk assessment, to undertake and actively participate and contribute to the process. Delegates will also learn how to use the Bowtie XP software to facilitate and undertake risk analysis, how to link barriers and control to risk management systems and procedures.

The output of the Bowtie risk assessment is a presentation of risks in pictorial form (see corresponding figure). The Bowtie diagram shows the causes (or threats) of an accidental event, its consequences, and the ‘barriers’ in place to prevent, mitigate, control or recover. The diagrams are easily understandable and provide an effective means of risk communication to the workforce. An exemplar Bowtie diagram is shown in the corresponding figure.
