Hazard

In the field of electrical / electronic / programmable electronic systems, the Hazard & Risk Analysis is performed in accordance with the requirements of the IEC 61508-1 standard which is the general standard (ie it is not addressed to any particular sector) on the functional safety of such systems when the safety-critical applications are used.
 
The objectives of the analysis are as follows:
  • Identify hazards and hazardous situations apparatus controlled (EUC - equipment under control) and its control system, in all reasonably foreseeable circumstances, including fault conditions and misuse;
  • determine the sequences of events that produce the identified dangerous situations;
  • determine the EUC risks associated with the identified hazard. For this purpose it is necessary to assess the likelihood of accadimanto of dangerous situations and the potential consequences of any dangerous situation.

The analysis is performed taking into consideration the following factors:

  • any dangerous situation detected, and the components that contribute to it;
  • the consequences and the probability of occurrence of sequences of events such allle every dangerous situation is associated;
  • the necessary risk reduction for each hazardous situation;
  • the measures taken to reduce or eliminate risks and dangers;
  • the assumptions made during the risk analysis including possible stress rate and the failure rate of the equipment; all the assumptions made about the limits of use or about human intervention should be detailed;
  • references to key information related to security systems for each stage of the security of the system life cycle.

The analysis aims are achieved by means of qualitative and quantitative methods described in IEC 61508-5.
