Learn when to use IEC 61508 or IEC 61511 for hardware and software in safety instrumented systems, covering new, proven-in-use, and already developed components.

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 hazard identification within the safety life cycle and how safety instrumented systems mitigate risks using techniques like checklist analysis, what-if analysis, FMEA, and HAZOP.

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.

Explore risk analysis using event tree analysis and inventory analysis to identify hazards, evaluate barrier effectiveness, and map event consequences in qualitative and quantitative terms.

Explore risk reduction techniques for IEC 61508/61511 safety, including risk graphs, risk matrices, layer of protection analysis, and fault tree analysis, guided by the Swiss cheese model of barriers.

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.

Apply reliability analysis to document the safety instrumented function's failure behavior against SRS requirements, using Markov analysis, fault tree analysis, and techniques to derive key parameters, including spurious trip rate.

Learn SIL verification using a simplified equation to estimate PFD for a CIF loop, with one-out-of-one configurations, referencing IEC 61 511 and ISA TR 84, and perform quick Excel calculations.

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.

Apply Markov analysis to a one out of two safety instrumented system, modeling three states (zero, one, two) with transitions and steady-state probabilities, including common-cause failure and repair rates.

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.

Explore safety instrumented system design and specifications, including initiator, logic solver, and final element, with de-energize to trip versus energize to trip, and fail-safe architecture per IEC 61508/61511.

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.

Learn how safety instrumented systems detect failures via normal operation, proof tests, and diagnostics, comparing coverage, frequency, and costs, with examples like watchdog timers and transmitter signals.

Learn to draw the chemical release inventory diagram for gas and liquid releases, covering ignition scenarios and outcomes like jet fire, vapor cloud explosion, flash fire, pool fire, toxic exposure.
