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 ISA-18.2/IEC 62682 alarm management lifecycle, can help address these issues and create an effective alarm system that better supports the operator.
If you have ever wondered how to determine when and if an alarm is needed, then this webinar is for you. It will also talk about how to establish an effective alarm limit, how to determine the importance of an alarm, and how to assign it to a class. It will show how key results of rationalization (including the cause, consequence and corrective action of each alarm) can be used to create operator response procedures which help operators respond more quickly and consistently to each alarm. Finally it will show how the use of a tool, such as exida’s SILAlarm, can effectively guide newcomers through the rationalization process.
