Learning outcomes
- Explain the key principles of alarm management lifecycle.
- Carry out a structured practical check or configuration task.
- Recognise common faults, risks and evidence needed for diagnosis.
Module 13 · Lesson 1
Alarm management lifecycle
Apply alarm philosophy, rationalisation, performance monitoring and management of change.
Before you begin
Alarm list, process hazard information and operator input.
Safety: Use site procedures, approved test equipment and competent supervision. Never bypass a protection or interlock without formal control.
Step-by-step learning
- Rationalise each alarm with cause, consequence, action and priority.
- Remove duplicates and convert non-actionable notifications to events or status.
- Measure alarm rate, floods, standing and chattering alarms.
- Review alarm performance after process or logic changes.
Ian's practical tips:
- More alarms do not make a plant safer; better alarms do.
- Operator participation is essential because they live with the results.
Fault-finding questions
- What should be happening, and what evidence proves it?
- Where is the last known correct signal, voltage, state or process condition?
- What changed immediately before the fault?
- Can the system be divided into smaller testable sections?
Practical activity
Create a one-page test record for this lesson. Include expected values, measured results, equipment used, risks controlled, defects found and the final proven condition.
