Which of the following describes a not-allowed action in the red tag process?

• A. Attaching a red tag to indicate corrective action is necessary
• B. Notifying the local AHJ within five business days after removal
• C. Printing red tags for a multiple period of years
• D. Having a red tag removed by any unqualified person

Answer: (D)

Red tags mark a part of the fire sprinkler system as out of service because there’s a safety hazard that must be corrected and verified before re‑commissioning. The action of removing that tag is tightly controlled: it must only be done by someone who is qualified to assess the corrective work and confirm the system is safe, typically the installing technician or the authority having jurisdiction. When an unqualified person removes the tag, there’s no reliable verification that the hazard was addressed, which can create a dangerous situation and is not allowed by the rules.

Attaching a red tag to indicate corrective action is exactly what the tag is for, signaling that action is needed before the system can be used. Notifying the local AHJ within the required timeframe after actions are completed is part of proper compliance and documentation. Printing or using red tags for extended, multi-year periods isn’t the central issue here and would depend on the specific tagging policy, but the decisive point in the question is who is authorized to remove the tag.
