Introduction to Safety Instrumented Systems for Technicians (IEC 61508/IEC 61511) – 1 Day Training Course
In the context of the operation and maintenance phase, Safety Regulators pay particular attention to the ongoing technical management of Safety Instrumented Systems. In this context, the technician plays a key role in the maintenance and modification of the Safety Instrumented Systems. Of particular importance is the concept of Proof Testing of the Safety Instrumented Functions. If Proof Testing is not undertaken strictly in accordance with the defined Proof Testing procedures then the tolerable risk will not be maintained.

Ron Bell, OBE, BSc (Hons), CEng, FIET
From 1992 until May 2006, Ron Bell was head of the Electrical and Control Systems Group in the Health and Safety Executive (the UK Safety Regulator). In 1998 he was appointed as one of the five UK members of the binational Channel Tunnel Safety Authority which is a post he held for 13 years.
He chaired one of the two IEC working groups responsible for developing IEC 61508 and also chaired one of the two teams responsible for the recent revision of IEC 61508. He is currently the chair of one of the two IEC Maintenance Teams responsible for the ongoing maintenance of IEC 61508.
He is a Director of Engineering Safety Consultants Ltd (ESC), a technical consultancy specialising in functional safety.
In 2005 he received the IEC 1906 Award for his work on functional safety and in particular IEC 61508. He received the OBE in the Queen’s 2006 New Year Honours.
Qualifications, Skills, Competence gained
- Certificate setting out the key topics covered in the course
- Enhanced knowledge of the requirements of Proof Testing and Proof Testing Procedures that will facilitate improved decision-making and better intelligence gathering to support an effective operation and maintenance regime
Who will benefit
The course is aimed at those who have responsibilities within the scope of IEC 61511. In particular:
- Technicians who have responsibilities for Safety Instrument Systems and, in particular, undertake Proof Testing in accordance with defined Proof Testing Procedures.
- Plant managers of process plants who have responsibility for the management of functional safety involving Safety Instrumented Systems.
- Control and instrumentation engineers, chemical engineers, mechanical engineers, electrical engineers who undertake or have responsibilities for Proof Testing of Safety Instrumented Systems
Course evaluation will be via feedback form.
