Within what timeframe will alarm maintenance personnel respond for catastrophic alarm failures dealing with PL 1 & 2 resources?

• A. Within 1 hour
• B. Within 30 minutes
• C. Within 2 hours
• D. Within 4 hours

Answer: (A)

The important idea here is the speed of response for catastrophic alarm failures involving the most critical resources. When a PL 1 or PL 2 resource experiences a catastrophic alarm failure, getting alarm maintenance personnel on site quickly is essential to assess the fault, prevent further risk, and restore protection. A target of within one hour reflects a practical yet urgent standard: it acknowledges dispatch and travel time while ensuring technicians begin diagnosis and remediation promptly. A 30-minute window is often not realistic given how teams are mobilized, while waiting two or four hours can allow the situation to worsen and increase safety or operational risks. So, aiming to have maintenance on site within one hour is the best balance for these high-priority resources.
