Course description
IEC 61511 SIL Determination
A practical training course in the appreciation of SIL Determination to the technical requirements of IEC 61511.
Industry today relies upon safety systems to maintain and protect operating assets. Businesses seek to maintain operating effectiveness and reduce spurious trips whilst achieving a safety target appropriate to the circumstances. Fundamental to this process is the determination and implementation of the safety requirements for the safety system. From the IEC 61511 standards, the Safety Integrity Level (SIL) is fundamental in ensuring a safety related system satisfactorily performs the required safety functions under all stated conditions within a defined time period.
It is an assessment of the risk reduction required to give a tolerable level of risk. Inappropriate SIL determination can affect the safety integrity of the asset protection envelope and may in some cases place the asset integrity under threat. In addition to this, unnecessary spend in capital and operational budgets can be incurred. In contrast, properly defined SILs allow for significant cost improvements to be achieved in both Greenfield and Brownfield operating environments. Asset operational effectiveness is ensured by periodic testing of safety instrumented functions to maintain SIL performance and optimise the cost of ownership.
Upcoming start dates
Suitability - Who should attend?
The course will be of benefit to all managers and engineers with a responsibility for the management and technical requirements of safety, health and environmental protective programmes.
Outcome / Qualification etc.
On completion of the course, you should be able to:
- Understand the concepts of SIL determination and the principles of IEC 61511
- Explain the key terms and concepts which underpin a systematic consideration process for safety and protective systems in respect to SIL
- Understand the importance of SIL Determination
- Determine where present practice is in line with the requirements of these standards and identify where improvements are necessary
