Recorded Webinars: The Philosophy Behind Effective Alarm Management
Development of an Alarm Philosophy document (APD) is one of the first and most important tasks in creating an effective alarm management program (and it is required by the ISA-18.2 and IEC 62682 standards). This webinar will discuss what topics should be addressed in an alarm philosophy (as required or recommended in the standards). It will also provide “tips and tricks” and “lessons learned” based on exida’s experience in the field and based on the ISA-18.2 Technical Report on Alarm Philosophy (which exida helped write). It will discuss which areas of the APD may depend on control system functionality and which areas are control system-agnostic. Specific examples will be covered such as prioritization, classification, use of Highly Managed Alarms, alarm suppression, and the use of alarm response procedures.

Blog Entry: Alarm Philosophy Development – Going to Great Lengths
Creating an alarm philosophy document is often the entry point into the ISA-18.2/IEC 62682 alarm management lifecycle. Many tasked with developing one are discouraged by its length and the barriers it creates. When it comes to using the philosophy document, a common concern is that if the document is too…
Recorded Webinars: SRA: Safety Reliability Analysis – Do You Engineer Above and Beyond?
When preforming an FMEDA, there are assumptions made that normal or typical engineering practices are followed. However, industry knows there are times when designers of a device or system will go above and beyond typical engineering practices or designs. That is where the SRA: Safety Reliability Analysis comes into play. The SRA allows the device designers to showcase their unique features or designs that improve safety. When there is extra safety designed into the device, it should be recognized; and the SRA can allow for that with a reduction in the failure rates for that device.
This webinar will look into what exactly a Safety Reliability Analysis (SRA) dives into, and what you can achieve with that closer look into safety.
