William Fairlie Process Engineer

Very good foundation level course for Process Engineers looking for deeper understanding of functional safety life cycle.

Liana Gasimova Senior Process Safety Engineer

I thoroughly enjoyed this class and have gained much knowledge.

Amy Whelan Project Engineer

Great course - has filled a gap for people who don't need the full TUV qualification for example.

Stéphane St.Yves Instrumentation Engineer

Very interesting training, well built, easy to navigate through and easy to use.

Albert Alvero Project Engineer

The content of this course is really good and it gave me the foundations I need.

Trevor Painting Trainee Control Systems Engineer

I have previously done Functional Safety Awareness courses but the knowledge learned in this course far surpassed what I have learned in the past.

Osama Saleem I&C Engineer

This course is useful. It has clarified most of the confusion that I had in this field. It has unique information and methods to deliver the ideas. I will be very happy to take another course from this website.

Cameron Roberts Process Engineer

This course provides an excellent foundation for those who may be required to deal with SIFs in the industry. The content is all applicable to industry and the real world.

Guillermo Pacanins Senior Process Safety Engineer

The course gives a special insight on Safety Instrumented Systems and their management in the process industry.

Ngor Deng Process Automation Safety and Commissioning Engineer

Great course! I have learned so much in regard to SIS, functional safety and SIS Safety Lifecycle from Hazard& Risk Assessment to Decommissioning of a SIF or SIS. The assessment quiz and practices questions at the end of each topic has prepared me to execute my current role effectively.

Krishnan Jayakumar Process Engineer

Excellent course for operation, design and process engineering. Subjects well designed, organised and presented perfectly with practical examples.

Alexander Banks Instrumentation Engineer

Very good course for anyone looking to improve their knowledge of functional safety. Online nature means you can complete at your own pace, which I found beneficial.

Scott Farrell E&I Technician

Overall I have increased my knowledge and recommend this course to anyone in this type of industry.

Fred Sartwell I&E Specialist

Well structured and challenging.

Jamie Dunn C&I Engineer

I thoroughly enjoyed this 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.
