The NTSB had in one of their Railroad Accident Reports stated where a locomotive engine had a piece of tape over the excessive speed alarm in the cab. Excessive speed was a factor in that derailment. Alarm overload! Glad to see this addressed. I did semiconductor wafer processing, and, some of the automated process machines had levels of alarms that could be set. The blue level alarms reported ever thing the machine did, even though those were normal events, I preferred to disable blue level alarms, to prevent alarm fatigue. But, I've heard of pipeline SCADA systems that would generate dozens of alarms per hour, causing alarm overload.
Thanks for commenting. I am so pleased to see real experts chime in on my high level reviews for new engineers. Comments can bring more value than the original video. Thanks again. 🙏
This is an amazing presentation video John on alarm management - watching this 2nd time. Is Alarm rationaalization & Alarm Bad Actor Management are same ? or Subset ?
Rationalization answers the questions: Is the alarm valid and necessary. A bad actor alarm can be necessary and valid just broken or in need of calibration.
