Safety Instrumented System E-Learning

An IChemE Accredited online course

Learn ONLINE about safety instrumented systems (SIS) and safety instrumented functions (SIF) in the process industry sector according to IEC 61511 and IEC 61508 functional safety standards.

Safety Instrumented Systems (SIS) are one of the vital independent protection layers for process safety. Applications include safe isolation of storage tanks, emergency shutdown, burner management and others found commonly in oil & gas, refining, chemicals and other high hazard industries.

The self-paced online course starts with hazard and risk assessment principles, using narrated and interactive lessons to explain how all elements of the SIS safety lifecycle are connected. From early concept through design and development, system testing and subsequent operation of an SIS; this course covers the entire safety life-cycle of an SIS. The course is entirely up to date with the latest IEC 61511 edition 2 international standard.

Safety Instrumented System learning objectives

  • Relate the history of several notorious process safety accidents with the safety life-cycle of IEC 61511
  • Differentiate between functional safety standards IEC 61508, IEC 61511 and their primary usage.
  • Describe the main SIS safety lifecycle and explain inputs and outputs of each stage.
  • Relate tolerable risk targets to the ALARP principle of risk reduction, including how Safety Integrity Level (SIL) applies within this overall context.
  • Explain the main elements of a typical SIS and differentiate this from other protection layer options for risk reduction.
  • Outline typical process hazard analysis methodologies and SIL selection techniques including risk graphs and LOPA.
  • Demonstrate an understanding of failure rates and how they apply to probability of failure in the context of safety functions.
  • Summarize the need and principles of regular inspection and proof testing of safety functions.
