Presented as a webinar on Tuesday, April 21, 2026, these slides introduce 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 show how FSAs can turn common PSM findings—like vague trip documentation, ad‑hoc testing, and unmanaged bypasses—into targeted improvement actions. Learn how to position FSAs as a value-added extension of  your existing PSM audit program, not an extra layer of bureaucracy.
