Functional Safety Assessment

It is a requirement of the standard that a Functional Safety Assessment (FSA) takes place at least once during the project, before the SIS is commissioned.

IEC61511 section 5.2.6 describes the content of the FSA’s and the possible project stages where they might take place. It also describes the degree of independence from the project that the FSA reviewer must have.

The purpose of a FSA is to make a judgement as to the functional safety and safety integrity achieved by the Safety Instrumented System.

The FSA will review the various stages of the SIS design, specifically looking at documentation relating to competency, risk assessment (HAZOP, Safety Integrity Level Assessment), SIL validation, software development and configuration control, system testing and validation (both factory and site), and operating & maintenance procedures.
