Blog Entry: Fake Fact: Final Elements should not be included in SIF evaluation
Ehh… If your safety action is stopping flow/closing a valve, how are you going to accomplish this if you consider that the remote actuated valve is not part of your SIF ? So, what is this myth based on? The title of IEC 61508 reads “Functional safety of electrical/electronic/programmable electronic…
Blog Entry: You want what?? You want it when??
Estimating time and cost for a project, or even part of a project, can be tricky. Breaking down the tasks into subparts must be done or you don’t stand a chance. Given enough time, you can develop an accurate estimate and put a good plan in place. But sometimes you…

Recorded Webinars: Making Use of Leading and Lagging Indicators
The IEC61511/ISA-84 Process Industry Sector Standard is predicated upon a performance-based Safety Lifecycle (SLC) to help reduce risk and to provide a foundation for the development, operation and maintenance of Safety Instrumented Systems (SIS). The SLC is composed of three phases: Analysis, Design/Implementation (Realization) and Operation and Maintenance. As a performance-based standard, End Users are required to develop Key Performance Indicators (KPIs) to facilitate performance monitoring. The basis of this is to ensure that the performance targets defined within the Safety Requirements Specification (SRS) for the SIS can be met and sustained throughout the life of the SIS.
This webinar outlines how KPIs based upon Leading and Lagging Indicators can help in maintaining performance and to help prevent potential future incidents from occurring. Accidents, such as the Texas City Isomerization Unit explosion in 2005, highlighted the need for such indicators and was a key recommendation in the Chemical Safety Board’s final, published, report on the accident.
By adopting Leading and Lagging Indicators, End Users can properly track performance and avoid potential hazardous situations by implementing proactive preventative measures.

Recorded Webinars: How to Effectively Use Certified Equipment in Fire and Gas Systems (Part 2: Flame Detection)
Flames, by their very nature, are intermittent and buoyant stimuli, making detection a uniquely challenging task. As the intention of flame detection is to detect small fires in order to take action to prevent a large uncontrollable fire, we need to ensure a robust reliability of our system. Verifying ‘system’ adequacy presents a number of challenges, including device certification, but also coverage analysis. Flame Mapping has become a critical step, particularly as these devices are so heavily reliant on a ‘field of view’ to the target fire. How would one review the flame detector coverage of a facility is adequate, and what size of fire should we be aiming to detect? This webinar will not only talk about the importance of flame detection certification, but will also investigate the typical processes of Flame Mapping and discuss the benefits of a consistent approach to Flame Detection Design throughout the lifecycle of a facility.

Recorded Webinars: Automatic Configuration of Safety Logic with the DeltaV SIS Configurator
For many years exSILentia® has provided an industry leading SIL verification tool that allows users to design their safety instrumented systems by defining architecture, voting, and equipment selection and ensuring the safety integrity of each instrumented function. Now it is possible to leverage your conceptual design specification to configure your entire safety control system with the click of a button.
With the DeltaV SIS Configurator, configuring your safety logic only takes a fraction of the time, so the SIS conceptual design can be finalized before programming begins. This eliminates any rework due to changing requirements and dramatically impacts project schedule and cost.
Recorded Webinars: IEC61511: Operations & Maintenance
This webinar looks at the changes made to the Operations and Maintenance requirements in the 2016 edition of IEC61511. This section of the standard has been “beefed up” to include more specific requirements regarding By-passing, Maximum repair time, Proof Testing, Competency, since most companies do not do a good job of following through on maintaining mechanical integrity and undertaking preventative maintenance. The webinar highlights some of these key areas and requirements, as well as discusses the benefits.
