Introduction to Functional Safety and Safety Instrumented Systems

Industrial processes require robust protection systems to prevent catastrophic incidents and protect lives. Understanding how to design and maintain Safety Instrumented Systems (SIS) is essential for modern engineers and operators working in hazardous environments. This text-based course guides you through the core principles of functional safety, aligning with key international standards. You will transition from understanding basic safety concepts to analyzing hazard risks, determining Safety Integrity Levels (SIL), and implementing safe design practices. What you'll learn: - Learn the foundational concepts of functional safety and the safety lifecycle. - Understand how to interpret and apply IEC 61508 and IEC 61511 standards. - Analyze process hazards using methodologies like HAZOP and Layer of Protection Analysis. - Determine Safety Integrity Levels (SIL) using qualitative and quantitative methods. - Design Safety Instrumented Systems including sensors, logic solvers, and final elements. - Explore the modern integration of cybersecurity within functional safety lifecycles. You will start with essential safety terminology and the safety lifecycle framework before moving into risk assessment, SIL determination, and system design. The course concludes with practical maintenance strategies and modern safety-system security considerations. This course is designed for beginners, junior engineers, instrumentation technicians, and operations personnel looking to build a solid foundation in functional safety with no prior specialized experience required.
