Safety Instrumented Systems (SIS) are a specific layer of protection that requires detailed knowledge and criteria for proper definition and installation based on functional safety principles and associated standard requirements. This paper focuses on providing guidance and criteria for conducting the following tasks: (1) how to link risk analysis results with functional safety concepts, (2) basics for systems verification via calculating the average Probability of Failure on Demand (PFDavg) and (3) available techniques to be used when verifying complex SIS.
