Traditional PSM and RBPS audits confirm that safeguards are documented, tested, and managed, but they often stop short of asking whether those safety instrumented systems truly meet their required risk reduction. This webinar introduces Functional Safety Assessments (FSAs) as a complementary deep dive that validates SIS lifecycle implementation against IEC 61511, from SRS quality and SIL verification to proof test strategy and MOC. Using examples from petrochemical, energy, chemical, and hydrogen facilities, we will show how FSAs can turn common PSM findings—like vague trip documentation, ad‑hoc testing, and unmanaged bypasses—into targeted improvement actions. Viewers learn how to position FSAs as a value-added extension of their existing PSM audit program, not an extra layer of bureaucracy.
