Alarm Quantity vs Alarm Quality
Conduct formal alarm rationalization aligned with IEC 61508 functional safety requirements to ensure alarm systems support rather than hinder operator response.

Regulations
Business Context
Alarm systems provide operators with early warning of abnormal process
conditions. Expanding alarm coverage improves visibility but may
overwhelm operators with excessive notifications during upset
conditions.
The Contradiction
More alarms improve process awareness.
More alarms reduce operator effectiveness.
Why It Exists
Alarm systems often grow over time without systematic rationalization,
resulting in nuisance alarms, duplicate notifications, and alarm
flooding.
Direction
Apply alarm rationalization, priority management, dynamic alarming, and
ISA-18.2 principles to ensure operators receive meaningful information
rather than excessive notifications.
