Management of Alarm Systems for the Process Industries
Specifies the principles and lifecycle processes for managing alarm systems presented to an operator through the control system, covering philosophy, rationalisation, design, implementation, operation, monitoring, change management and audit.
Always verify against the current published text before relying on it for a submission or inspection.
Scope & applicability
All alarms presented to the operator through the control system — from the basic process control system, annunciators, packaged equipment and safety instrumented systems — across continuous, batch and discrete processes. It governs whether an operator can act on what the system tells them; it does not govern the safety function itself, which is IEC 61511.
Key requirements
- A documented alarm philosophy defining what qualifies as an alarm, priority assignment and performance targets
- Rationalisation — every alarm justified against a defined consequence, response and time to respond
- Alarm-performance monitoring against benchmarks, including average and peak alarm rates per operator
- Controlled management of change and periodic audit of the alarm system
- Edition 2.0 (2022) replaces the 2014 first edition
Implementation tips
- Rationalisation is the step that is skipped and the one that produces the benefit: an alarm with no defined operator response is a notification, and it should not be configured as an alarm
- Measure the flood, not the count — average rate hides the upset condition where the operator receives hundreds of alarms and cannot prioritise, which is the failure mode that appears in incident reports
