Recorded Webinars: Safety Alarms: At the Intersection of Alarm Management and Functional Safety
“Safety Alarms” (aka Safety Related Alarms) are commonly used as safeguards or independent protection layers to prevent the escalation of hazardous scenarios. Despite this simple purpose, there is a wide range in the interpretation of what a safety alarm is, its requirements and how it should be managed. Some schools of thought advocate that safety alarms have a risk reduction > 10 and must be implemented in a safety instrumented system (SIS) that is compliant with IEC 61511. Others would say that all alarms implemented in an SIS are safety alarms. Still others would say that safety alarms can be implemented in a BPCS, and they may be assigned a risk reduction factor ≤ 10.
This webinar will highlight the current “body of knowledge” contained in ISA-18.2, EEMUA 191, UK HSE’s OG47, IEC 61511, and ISA-84. It will also discuss where industry is heading in terms of new guidance, interpretations, and requirements. Organizations such as the UK HSE, NAMUR, and ISA are updating existing guidelines or developing new ones. ISA is developing a new standard on Safety Controls, Alarms and Interlocks (ISA-84-91.03).
This webinar will discuss how to identify what is a safety alarm (and what this means to the end user). It will also discuss how risk reduction, safety integrity level, identification as a safeguard or independent protection layer, and use as a mitigation or prevention barrier, impacts requirements.
Recorded Webinars: The Optimal SIL Certification Path for all Manufacturers
Due to the rapid growth of IEC 61508 Safety Integrity Level (SIL) Certification, many companies who haven’t achieved certification are now trying to catch up and understand what is involved. Manufacturers now have MANY different options when obtaining certification. Certification is now molded around the manufacturer. How much time will it take? How much will it cost? How many man hours will be consumed to achieve certification? What are the benefits? These are now ALL questions the manufacturer gets to choose.
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.
