Recorded Webinars: How Site Operations and Maintenance Impact Equipment Failure Rates
Many think about an equipment’s failure rate as a fixed parameter. In fact, the same equipment will exhibit various failure rates depending on the operations and maintenance practices at a given site. We have found through analysis of field failure data that identical equipment can exhibit quite different failure rates at different sites even within the same company. This webinar explains this phenomenon, demonstrates how these differences can be measured and predicted, and illustrates how predictive methods can be used effectively to perform cost/benefit analysis of proposed changes in operating and maintenance practices before the changes are implemented.
Blog Entry: If an Alarm Occurs and the Operator doesn’t Ack it, was it really an Alarm?
Similar to the thought experiment “If a tree falls in a forest and no one is around to hear it, does it make a sound?”, we ask - If an alarm is generated, and the operator fails to acknowledge it, was it really an alarm? A prevalence of unacknowledged alarms…
News Item: Johnson Controls receives ISASecure CSA conformance certificate from exida
The ISASecure Program announced that Johnson Controls, the global leader for smart, healthy and sustainable buildings, has earned the world's first ISASecure CSA certification for its smart buildings products with YORK YK and YZ centrifugal chillers. “Johnson Controls continues to demonstrate leadership in cybersecurity for smart buildings,” said Mike Medoff,…
Recorded Webinars: OPC (Open Platform Communications) and Safe Operation
OPC is an essential standard for industrial communications that enables universal connectivity and interoperability. It started in 1996 and has been part of numerous industrial systems and architecture for years.
While many use the OPC or OPC derived software and system architecture in the operation, not many would actively relate OPC with safety. This webinar hopes to discuss a few of the concepts within OPC and map those to functional safety, alarm management and cybersecurity for industrial systems.
Blog Entry: Measuring Performance – Why Are We Not Doing This?
Part of the changes to the IEC61511 standard in 2016, some five (5) years ago now, was to emphasize the need to do a better job with regards to the Operations and Maintenance phase of the safety lifecycle . One of the key aspects of the Operation and Maintenance phase…
News Item: How exida’s Automated Software Tools Redefined Functional Safety
For decades achieving safety certification was an opaque process. Now software tools can help you do it yourself. It is said that necessity is the mother of invention. Just over 20 years ago, two men who met on opposite sides of a product safety certification process ended up proving this…
Blog Entry: Can Nuisance Alarms “Break” the Operator?
Study after study finds that something like 80% of industrial incidents (give or take) are caused by Human Error. Incidents involving human error often include a failure of the operator to respond to an alarm, which is often directly or indirectly caused by nuisance alarms. Poor alarm management has multiple…
Recorded Webinars: Understanding Published Equipment Failure Rates
How They Are Calculated, What They Tell Us & When They Can Be Used
It is not uncommon to find published failure rates with significantly different values for very similar equipment. These differences stem from the ways in which the failure rates were produced based on different approaches and different underlying assumptions. To used published failure rates effectively in assessing equipment safety performance, it is imperative to understand how failure rates are calculated, how to interpret the numbers, and recognize when those values can and cannot be used. This webinar covers these areas assuming basic knowledge of functional safety concepts.
Blog Entry: FAQ: More Failures with Actuated Valves than what published failure rates indicate?
During a recent exida webinar we received the following question: We tend to see more failures with actuated valves, than what manufacturers published failure rates would indicate! Any reason? There are several reasons. Some manufacturers publish data based on field return data where they classify failures caused by customers as…
