What You Will Be Able to Do
- Explain functional safety according to IEC 61511 and its relationship to IEC 61508.
- Apply the functional safety lifecycle to SIS — from hazard analysis and SIF specification through operation, maintenance, and modification.
- Use Functional Safety Management concepts: lifecycle planning, competence, verification, validation, assessment, audits, and documentation.
- Apply HAZOP and LOPA to identify SIFs and determine required SIL and Risk Reduction Factors.
- Develop and review Safety Requirements Specifications for SIS and SIFs.
- Apply hardware concepts — Type A/B, voting, redundancy, HFT, SFF, and architectural constraints.
- Differentiate diagnostic tests and proof tests and understand their impact on PFD and availability.
- Perform and interpret PFD calculations using simplified equations and reliability modelling.
- Handle application program requirements, V-model testing, and software systematic capability.
- Assess certificates, prior use, and proven-in-use claims for devices, subsystems, and SIS solutions.
- Plan operation, maintenance, repair, modification, and bypass of SIFs without losing SIL compliance.
- Sit the FS Specialist and TÜV exams with confidence and start your pathway to Professional, Expert, and Master certification.
