- Safety Integrity LevelSIL stands for Safety Integrity Level, which is a measure of safety system performance in terms of probability of failure on demand (PFD)1. SIL studies are a formal method of assessing the probability that a functional safety system will fail when it is needed2. The assignment of SIL is an exercise in risk analysis where the risk associated with a specific hazard is calculated without the beneficial risk reduction effect of the safety instrumented function (SIF)3. The assessed probability of a safety system failing acts as a measurement of the level of risk reduction that the system provides2.Learn more:âś•This summary was generated using AI based on multiple online sources.

SIL stands for Safety Integrity Level. A SIL is a measure of safety system performance, in terms of probability of failure on demand (PFD). This convention was chosen based on the numbers: it is easier to express the probability of failure rather than that of proper performance (e.g., 1 in 100,000 vs. 99,999 in 100,000).

That unmitigated risk is then compared against a tolerable risk target.
