Alarm rationalization for increased plant safety

Plant Historian AR - Alarm Rationalization

Increased plant safety as a result of sustainable alarm management


Alarm rationalization describes the comparison of alarms with the respective alarm concept as well as the determination and documentation of the reasons for an alarm. Alarm rationalization also includes the configuration of alarm parameters.

An important part represents the recording of possible consequences and corrective measures for occurring alarm including their priorization. Generally, priorization depends on the consequences in cases of disregard of alarms (damage to humans, environment and machine) and the remaining response time for the operator in an alarm situation.

Procedural instructions and recommendations for action constitute an optimal support for the operator .
