Blog Entry: Safety Alarms and Why ISA-84.91.03 is Needed
On July 27, the US Chemical Safety Board (CSB) issued a Factual Update on their investigation into a release of water containing a toxic gas (hydrogen sulfide) and subsequent fatal injuries sustained at the Aghorn Operating Waterflood Station. While it is typically not a good idea to comment on investigations…
White Paper: Integrated Safety for a Single BMS
Evaluation Based on Siemens Simatic PCS7 System Any industry that has a requirement for a heated medium, whether it is used for process, utilities or emissions, utilizes equipment that has combustion controls and combustion safeguards. There has been an evolution in these controls from a traditional control that separates the…

News Item: New White Paper: Application of Safety Instrumented Systems in Liquified Natural Gas (LNG) Processes
At first glance, one might assume that Liquified Natural Gas (LNG) processing is simply a compression and cooling process. Deeper observation reveals unique process challenges of flammable and explosible materials, high-pressure rotating equipment, and cryogenic conditions. LNG facilities are typically developed by connecting highly specialized process units designed and constructed…

Recorded Webinars: IEC 61511 and Failure Rates
This webinar will help in understanding the changes to IEC61511 2016 regarding failure rates for use in the reliability calculations (i.e. PFDavg or PFH) of random failures for SIF equipment. Some certification agencies have been issuing certificates for equipment with extremely low failure rates, when compared to industry databases. This can lead to optimistically and dangerously low estimates of PFDavg/PFH for SIF equipment. The webinar will identify how to look at these failure rates and to make a quick judgement on whether they meet the requirements of IEC61511.
What you will learn:
- How to identify bad failure rates
- What to look for on certificates
- Where to be able to compare certificates
Who should attend:
- Engineering companies
- End Users
- Supervisors & Managers
News Item: Integrated Automation Lifecycle Symposium Hosted by exida
Please join us for a three-day virtual Symposium on the integrated automation lifecycles: Functional Safety, Alarm Management, and Cybersecurity. Effective risk management requires consideration of all three lifecycles, by integrating relevant activities across these lifecycles significant improvements can be made. A maturity based process for improving each of these lifecycles…
Blog Entry: IEC 62061 Machine Safety: “It’s simply the right thing to do”
I can't begin to tell you how many of our customers share with us how lucky they have been to be incident-free at their plant. Or, because they have not had an incident in over 10 years, it is hard to justify the cost of a Machine Hazard & Risk…
Blog Entry: Back to Basics: Failure Rates - λS
The Greek symbol λS represents safe or spurious failure rates in functional safety expressed in the unit of measurement of FITs which can be determined through FMEDAs . ( FITs (λ) are failures per billion hours, expressed by 10 -9 hours). λS is the number of safe of spurious failures…
Blog Entry: IEC61511 and Failure Rates
Most end users I teach in our FSE100 class are not really aware of or fully, understand when we talk about failure rates. For example, what’s a FIT mean? For those end users more versed in this, they understand what is meant by a FIT. Essentially a device can have…
Recorded Webinars: Assessing Common Cause for BPCS Shared Components
In an ideal world there is complete independence between a Safety Instrumented System (SIS) and the Basic Process Control System (BPCS); however, perfect separation cannot always be achieved leading to the potential for common cause failure that could defeat both layers of protection simultaneously. IEC 61511:2016 requires that the SIS design must identify and take account of common cause failures. This webinar will review some of the potential sources for common cause failure and will provide examples on how to account for this in the SIL Verification calculation.

Recorded Webinars: Cybersecurity Incident Response - When Disaster Strikes, How Will You Respond?
In today’s industrial control environment, where over half of ICS have experienced an attack in the last two years, it is not a question of if an attack will occur, but a question of when. When an attack does occur, how will your organization respond? Do you have monitoring in place to detect security excursions? Once the excursion is identified what measures are in place today to respond to and mitigate the concern? This webinar will focus on the keys to an effective Cybersecurity Response and Recovery plan, starting at the moment the attack is discovered all the way to when operation is successfully restored.
