Modern control systems make it easy (maybe too easy) to add alarms without significant effort, cost, or consideration for whether they are truly needed. This has led to alarm systems that often hinder, rather than help, operators by subjecting them to nuisance alarms, alarm floods, incorrectly prioritized alarms, and general alarm overload. Alarm rationalization, a proven alarm management technique and one of the stages of the ISA-18.2 / IEC 62682 alarm management lifecycle, can help address these issues and create an optimal, effective alarm system.
The presentation will touch on best practices for rationalization as well as the most common pitfalls. It will also demonstrate how effective alarm rationalization can lead to reduced downtime, reduced operational risk (insurance premiums), and reduced cost of operations, while improving operational discipline and operator effectiveness.
