One of the most important stage of technical system functional safety analysis is defining the safety-related functions as well as determining a safety integrity level (SIL) for each defined function. A properly carried out hazard identification process is the necessary condition for correct definition of the safety-related functions. Determining the safety integrity level (SIL) is based on risk assessment taking into account risk acceptance criteria. It guarantees accurate results which means that the risk associated with technical system is under good control and the risk level can be reduced to acceptable one. There are several safety integrity level determination methods and techniques described in normative documents and many papers. This article is aimed at presentation of some of them and in addition a new approache are outlined.
