About the seminar

 

In this era of economic constraints there’s an ever increasing need for operating assets to function to their maximum potential – and that’s true across any sector – but just as important is the need for these assets to continue to perform safely.

Industry increasingly relies upon safety (instrumented and electrical) systems to maintain and protect operating assets. The concept of Safety Integrity Levels (SIL) is fundamental in ensuring a (safety related) system satisfactorily performs the required safety functions under all stated conditions, within a defined time period.

Accurately determining the Safety Integrity Level for your system is a topic which generates significant debate within industry across the safety-related community, particularly in relation to standards such as IEC 61508, IEC 61511 and IEC 62061.

 

A definition of a SIL (Safety Integrity Level)

Safety Integrity Levels (SIL) are measures of the safety of a given process or machine. To say that a process meets a specific SIL is to say that it was developed using appropriate techniques and measures to ensure that it meets the systematic failure requirements of a specific safety function at that level. Levels are ranked 1-4 and the higher the number, the safer the process.

There are four discreet integrity levels, SIL 1 - 4. The higher the SIL level, the higher the associated safety level and the lower the probability that a system will fail to perform properly (source: Buncefield Investigation).

For example: a dangerous machine, that if it failed may cause serious injury or death, may be awarded a certain SIL. This level would be 1, 2, 3 or 4.

 

So many reasons to attend…

  • Meet the minds behind the IEC 61508 safety standard
  • Immerse yourself in topical case studies of SIL determination in practice across a range of industry sectors to better inform and better maximise the effect and efficiency of your system safety verification procedures
  • A neutral setting to inspire debate into whether the benefits and assurance provide by a particular SIL can be achieved by alternative means
  • Gather legal insights into this unforgiving area of and ensure you stay the right side of the law

The invited speaker seminar day on 12 December is preceded by two optional workshops.

 

How do I register?
