WebAn SIF’s sensors, logic solver, and final elements act in concert to detect a hazard and bring the process to a safe state. Each SIF serves as a protection layer to bring the effective hazard frequency down below the acceptable hazard frequency. To do this, each SIF must have a minimum risk reduction factor.
