Fault Tree Analysis (FTA) is a formalised deductive technique allowing the investigation of possible causes of undesired system states, referred to as Top Events. In doing so, these states are associated with abnormal system behaviours caused by failures at component level and/or by external events. A Top Event can be any system state considered critical from the risk viewpoint. One can think of an explosion in an industrial plant, the release of radionuclides in a nuclear reactor, the derailment of a high-speed train. Top Events can also represent unavailability of an alarm sub-system.
