Deferring alarms is done on what basis?

• A. All-at-once basis
• B. Random basis
• C. Based on alarm type
• D. Case by case basis

Answer: (D)

Deferring alarms is decided on a case-by-case basis because each alarm comes with its own context and potential impact. You weigh factors like what triggered the alarm, the current condition of the system, whether the issue can safely be tolerated for a period, and what resources are available to respond or fix it. This individualized judgment helps protect safety and maintain operations without overreacting or missing real problems. If you deferred all alarms at once, you might overlook critical conditions or waste time on non-issues. Deferring randomly would lead to inconsistency, and deferring based only on the alarm type ignores how the same type can have very different implications depending on the situation. So you evaluate each alarm in its own setting and decide accordingly.
