Which element on the red tag verifies who performed the service or inspection?

• A. Signature of service person or inspector
• B. Owner's signature
• C. Notary stamp
• D. Supervisor's initials

Answer: (A)

The key idea here is accountability for the work done on the system. On a red tag, the element that proves who performed the service or inspection is the signature of the service person or inspector. This signature provides a direct, verifiable link to the individual who carried out the work, which is essential for records, follow‑ups, and any future inspections. An owner’s signature only confirms ownership or receipt, not who did the work. A notary stamp isn’t standard for identifying the technician, and a supervisor’s initials might show oversight but don’t prove which person actually performed the service. So, the technician’s or inspector’s signature is the best way to verify who performed the service or inspection.
