What is the retention period for the event record after a detector trip due to automatic detector action?

• A. 7 years
• B. 1 year
• C. 5 years
• D. 10 years

Answer: (A)

The key idea here is how long records of safety events, specifically detector trips triggered by automatic detector action, should be kept to support safety investigations and regulatory reviews. When an automatic detector trips, a detailed event record is created—capturing when it happened, where, what detector triggered, what actions were taken, and any follow‑up repairs or adjustments. Keeping this information for seven years ensures there is enough historical data to identify trends, assess whether equipment or procedures need changes, and demonstrate compliance during audits or inquiries. A shorter retention period might lose important context needed for thorough root‑cause analysis, while a much longer period can add unnecessary archival burden. Seven years provides a practical balance, which is why it’s the best choice.
