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.

What others have said about this course

I thoroughly enjoyed the Safety Instrumented System course. Considering it is a foundation course, it teaches you some extremely useful and relevant information, whilst pushing and testing your knowledge of each completed module by means of a test at the end of each stage.

The course content, formulation, presentation, example and testing method are excellent. Practical approach. Excellent course for practical application.


Lead Process Engineer, Qatar

Overall a very good course and investment. The cartoons with Bob were great; makes association with everyday events surrounding value of the safety requirements specification more useful.”

Project Engineer, Saudi Arabia

The SIS Foundation e-Learning is one of the most comprehensive Functional Safety courses available through the internet. The course content targets Functional Safety Management, as well as engineering and operations according to IEC 61511:2016 Ed. 2. The course gives a special insight on Safety Instrumented Systems and their management in the process industry.


P.Eng, Process Safety, Canada

The Safety Instrumented System course gives a very good outline of Functional Safety requirements in the process industries. It is challenging and makes you think about what you are learning. 

Process Engineer, UK

The course was well presented, contained useful information and was easy to navigate. Overall I have increased my knowledge and recommend this course to anyone in this type of industry.

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.
