What is the intent of tracking nuisance and false alarms?

• A. To document all alarms for records
• B. For the ESS NCO to investigate and address the root cause of these alarms when a negative performance trend is detected
• C. To reduce maintenance costs
• D. To penalize operators

Answer: (B)

Tracking nuisance and false alarms is about turning alarm data into action. When alarms occur that aren’t signaling real problems, they create distractions and mask true issues. By logging these alarms and watching for patterns, you can spot when a sensor, configuration, or process is drifting toward a fault and needs attention.

The key value is the response to a negative performance trend: the ESS NCO investigates the underlying cause rather than just noting the alarms. They look for root causes—like sensor miscalibration, wiring faults, or environmental conditions—and implement corrective actions to prevent recurrence. This approach improves system reliability, reduces unnecessary alarm activity, and makes maintenance and operations more efficient.

While recording alarms matters and some improvements may lower costs, and while it wouldn’t be about punishing operators, these outcomes are secondary to the goal of resolving the real problems driving alarms.
