Abstract :
Alarm rationalization is a structured and systematic process used to evaluate alarms within an Industrial
Automation system to ensure that each alarm is meaningful, actionable, and properly justified. The objective is to confirm
that every alarm has a valid reason to exist, that it alerts the operator to a real operating condition requiring attention, and
that its setpoint, priority, and response timing are appropriately defined. Plant trips, defined as unplanned shutdowns of
equipment or process systems, can significantly affect operational continuity, reliability, and process safety. A disciplined
investigation process is essential to determine the initiating event, contributing factors, and root causes, and to ensure
effective corrective actions are implemented. This article presents a structured approach to plant trip investigation, covering
incident reporting, investigation team formation, data collection, sequence-of-events analysis, root cause analysis, corrective
action development, report preparation, implementation, and knowledge sharing. The article argues that plant trip
investigation is not merely a troubleshooting activity but a systematic learning process that strengthens reliability and
continuous improvement in industrial operations.
