- SIL 0 refers to safety systems that are not required to meet a safety integrity level standard123. It is also defined as ‘No protection layer needed’ or ‘No safety requirements’23. A probability value of 0 means the outcome is impossible4. Although individual components of safety systems are not given SILs, these components may be designed by manufacturers to be suitable for use at specific safety integrity levels1.Learn more:✕This summary was generated using AI based on multiple online sources.

Safety integrity level - Wikipedia
In functional safety, safety integrity level (SIL) is defined as the relative level of risk-reduction provided by a safety instrumented function (SIF), i.e. the measurement of the performance required of the SIF. In the functional safety standards based on the IEC 61508 standard, four SILs are defined, with SIL4 being the … See more

Jul 27, 2020 · There are four discrete integrity levels associated with SIL: SIL 1, SIL 2, SIL 3, and SIL 4. The higher the SIL level, the higher the associated safety level, and the lower probability that a system will fail to perform properly.
