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…

Recorded Webinars: What is Cybersecurity Hygiene, and How Do I Implement It?
Cybersecurity hygiene is a set of basic practices that can be taken by all personnel to protect the health of hardware and software of computer-based systems. Just as traditional hygiene measures are needed to limit the spread of viruses and disease, cybersecurity hygiene is needed to limit the spread of computer viruses and cybersecurity attacks. Recent studies have shown that well over half of all automation systems have experienced a damaging cybersecurity incident in the last two years. To better protect automation systems against these types of incidents, cybersecurity hygiene is a critical first step. This webinar will provide a deeper look into the importance of cybersecurity hygiene as well as provide actionable steps for improving cybersecurity hygiene within your organization.

Recorded Webinars: Reduce Cost & Time to Market by Improving FMEDA predictions with new Component Reliability Database
Failure Modes, Effects, and Diagnostics Analysis (FMEDA) is a staple in functional safety engineering for design & development of automatic protection systems to the IEC 61508 family of standards (IEC 62061, ISO 26262, IEC 61511). FMEDA is the most common technique for quantitative evaluation of safety and reliability performance metrics and for evaluating whether a product will fail in a predictable manner (fail-safe). Experienced engineers know that FMEDA results, however, are only as good as the failure rate data used to create them and the associated component reliability database (CRD). A new CRD from exida overcomes limitations of current industry reliability handbooks to deliver more accurate results that helps product designers reduce cost and time to market. Integration into the exida FMEDAx tool minimizes the chance of human error and reduces engineering time.
