Bow ties provide an excellent visualization of hazard scenarios that cause the realization of important hazards. They are indispensable in communicating the hazards of processes to front-line personnel, such as operators, and other stakeholders, such as managers. Additionally, they support the essential tasks of ensuring the adequacy of process safeguards and properly managing their performance. Bow tie analysis is increasingly being used by safety practitioners.

PHAWorks RA Edition incorporates the capability to automatically generate bow tie diagrams from the hazard scenarios in PHA worksheets. Once generated, users can modify bow tie diagrams directly. Additionally, new bow tie diagrams can be created manually from within PHAWorks RA Edition.
