Safety Integrity Level

Safety Integrity Level (SIL) is an exercise in risk research where the risk associated with a specific risk, which will likely be protected against by way of Safety Instrumented Functions (SIF), is determined without the advantageous danger reduction impact in the SIF. Where “unmitigated” danger can be contrast against a endurable danger focus on. This big difference between the “unmitigated” danger as well as the endurable danger, should the “unmitigated” danger can be beyond endurable, must be attended to by means of risk reduction in the SIF.
