As part of the Public Transport sector, the Risk Analysis is carried out in keeping with the requirements defined in CELENEC EN 50126-1, following the guidelines expressed in CELENEC CLC / TR 50126-2.
 
Starting from the results obtained from the Preliminary Risk Analysis we proceed to a more accurate identification of dangerous situations and to the determination of the risk associated with them.
 
The standard dedicates to this activity an entire phase of the life cycle RAMS system, but, in view of the continuous risk management, the risk analysis, if necessary, must be repeated in the other phases of the cycle.
 
 The objectives of the risk analysis are the following: 
  • systematically identify and classify in order of priority all dangerous situations, reasonably foreseeable as associated with the system in its application environment;
  • identify the sequence of events which result in to dangerous situations;
  • assess the frequency of occurrence of each hazardous situation;
  • assess the likely severity of the consequences of any dangerous situation.
As already done for the Preliminary Risk Analysis the identification of dangerous situations is carried out following the structured approach documented in CLC / TR 50126-2, based on the grouping of independent  hazard sets   and with common characteristics, called hazard cluster. For each cluster is drawn up a checklist containing the hazard identified and its description.
 
A second method commonly applied in the identification of dangerous situations is to create a list of system hazards based on functional approach ; each hazard identified is allocated to one of the following categories: infrastructure, energy, material, control & command.
 
Finally, during the risk analysis activities, the register of dangerous situations (hazard-log) is constantly updated
