SIL Ratings for Fire & Gas Systems – Are We Barking Up The Wrong Tree?

Paul Gruhn – ICS Triplex

Current standards covering fire and gas systems are prescriptive and focused for commercial applications. Many users believe there is a need for performance based standards for such systems used in industrial applications. However, there is considerable debate whether fire & gas systems should have SIL (Safety Integrity Level) ratings at all. Vendors are naturally interested in promoting certified hardware in order to differentiate their products. Yet considering the differences between safety instrumented systems and fire & gas systems, focusing on the performance of the actual fire & gas hardware alone may be a misleading and questionable practice. This paper reviews a) the differences between safety instrumented systems and fire & gas systems, b) how typical voting of fire & gas sensors not only reduces nuisance trips (which is desirable) but also reduces the likelihood of the system meeting the performance target and actually responding to a true demand (which is not desira ble), and c) why concepts and standards that apply to safety instrumented systems may not be appropriate for fire & gas systems.

The above topic will be presented as the keynote address by Paul Gruhn of ICS Triplex at the upcoming Safety Control Systems Conference in Calgary on May 11-13 2010.

IDC Technologies is proud to host the Canada’s foremost gathering of Safety Industry Professionals. This conference is committed to bringing you the latest information in the area of safety with an impressive selection of local and international speakers lined up.

This conference will focus on the technology and application of safety-related control and instrumentation systems in the chemicals, energy, mining and manufacturing industries. It will examine the complex and challenging issues of using control systems technology to maintain and improve the safety of people and plant whilst ensuring profitability.

We welcome our two keynote speakers Mr Edward Marszal, President of Kenexis Corporation from the USA who is an ISA Fellow and former Director of the ISA Safety Division and safety expert Mr Paul Gruhn, Training Manager at ICS Triplex, ISA contributor/author and household name in the global safety industry. Both Edward and Paul will be presenting a half day pre-conference workshop on the 11th May 2010.

You will also hear from FSE Global, Exida, Fluor, Hinz, ACM Facility Safety, Alberta Oilsands SAGD Project, Stantec Consulting, SNC-Lavalin Inc, Worley Parsons, Combustion Solutions Inc and ABB Canada.
