About this course
Functional Safety (IEC 61511) and SIL gives delegates a structured, practical understanding of functional safety life cycle and IEC 61511 requirements, then builds the skills to apply SIL determination and LOPA, safety instrumented system design and verification, validation and proof testing in real work. HSE training courses on risk assessment, investigation, audit and safety leadership for high-hazard industries and every workplace. One of our most requested courses. Demand for these skills is expected to rise strongly by 2027.
Sessions are led by practitioners with at least 15 years in the field, and mix short input with exercises, case studies and group work, so delegates return with methods they can use straight away.
Who should attend
HSE professionals, supervisors, engineers, auditors and line managers responsible for safe operations. No specialist prerequisites are required for the Practitioner level; Foundation, Advanced and Executive versions are available on request.
