A Bow Tie diagram offers visualisation of hazards, threats, barriers and consequences in such a way as to facilitate workforce understanding of hazard management and their role in it. In this approach, hazard is represented by a top event (realization of hazard) which can be triggered by one or several threats and result to one or several consequences. The barriers are provided to protect the system from these threats or consequences.

 

During Bow Tie sessions, the risk analysis team of Ergonomia will cooperate with theresponsible personnel of the facility, guidethem through the Bow Tie method and suggest additional technical andorganizational barriers according to relevant standards and best practice in order to demonstrate that each risk is as low as reasonably practicable (ALARP).
