Safety Instrumented Systems Online E-Learning

An IChemE accredited online course

Learn online about safety integrity level - SIL rated safety instrumented systems (SIS) and safety instrumented functions (SIF) in the process industry sector.

Master IEC 61511 - BS EN 61511, and IEC 61508 - BS EN 61508 functional safety standards.

Sample certificate for safety instrumented system online course - IChemE and eFunctionalSafety
Award from IChemE of 18 CPD Hours

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 life-cycle are connected. From early concept through design and development, system testing and subsequent operation of an SIS; this course covers the entire life-cycle of an SIS. The course is entirely up to date with the latest IEC 61511 edition 2 international standard.


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.

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.”

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.
