The Challenge
With the modernization of control systems, the addition of process alarms has become easy. In a genuine effort to protect against unsafe conditions, the default alarm strategy has shifted toward alarming for every possible undesirable scenario. As a consequence, operators are overwhelmed with nuisance alarms they cannot act on, already know about, or that have no impact based on current operation. Once alarms become a nuisance rather than a tool to support operators, they gradually become ignored.
