WebApr 3, 2024 · Abstract. Instrumented protective function (IPF) is a safety function designed to achieve a safe state for a specific hazardous event. An IPF loop is made up of initiators, logic solvers and final elements. IPF is classified with a specific safety integrity level (SIL), which must be met throughout its life-cycle. IPF failures can cause severe consequences … WebJul 24, 2024 · Safety Integrity Levels (SILs) are a measure of the impact that a Safety Instrumented Function (SIF) has over the risk associated with a specific hazard. The higher the SIL level is, the more efficient that function will be at reducing the risk it mitigates. SIL 3 is one of the safety integrity levels defined by the IEC 61508 standard.
