Functional Safety Certified Expert- IEC 61508/ IEC 61511

Examine how a cascade of safety failures at Bhopal triggered a catastrophic methyl isocyanide release, with failed alarms, neglected procedures, and nonfunctional safety systems.

Explore the onion model of risk reduction, detailing ten layers of protection—five prevention and five mitigation—and how independent layers are credited to reduce risk to tolerable levels.

Explain that IEC 61511 mandates security risk assessment for safety instrumented systems, per clause 8.2.4, to identify vulnerabilities that could prevent the CIS from performing its safety function.

Explore failure mode and effects analysis (fmea) across products and processes, detailing three types and the risk priority number calculation to guide mitigation.

Explore Hazop guide words and process parameters like flow, pressure, level, and composition, and learn how failures such as power or instrument air can alter operations and create hazards.

Explore fault tree analysis to identify root causes in complex systems using a top-down diagram with and/or and voting gates, emphasizing early design and visual problem solving.

Apply hazop and lopa on a hp separator case to quantify risk, assess protection layers, and determine seal classifications for a functional safety system.

Learn how to craft a comprehensive safety requirements specification for safety instrumented systems under IEC 61511. Identify required content, roles, and review flow from hazard analysis to system design.

Explore self verification with Markov analysis, a practical two-state (ok and failure) method used in SIL calculations under IEC 61508 and IEC 615W1, including repairable and non-repairable scenarios.

Use Markov analysis to verify a safety instrumented function's seal, compute the loop average value, availability, and risk reduction factor from a four-state model.

Learn how redundancy, diversity, and voting in safety instrumented functions improve availability and reduce spurious trips, using initiators, logic solvers, final elements, and various voting schemes.

Explore safe, dangerous, and detected failure types in SIS design, including safe detected, safe undetected, dangerous detected, and dangerous undetected failures, and how diagnostics reveal them.

Explore API 14C for offshore platforms, focusing on safety flowchart, safety analysis, and protection concepts with practical examples of symbols and safety devices.
