What must yellow tags include as a verification from the service person or inspector?

• A. Printed name of service person or inspector
• B. Sign-off stamp
• C. Signature of service person or inspector
• D. Notation by owner

Answer: (C)

The key idea is that the yellow tag must authenticate who performed or approved the work. A signature from the service person or inspector provides a clear, verifiable link to a specific individual responsible for the maintenance or check, creating a traceable record for inspectors or authorities later. A printed name alone can be misattributed, a sign-off stamp could be used without tying it to a particular person or event, and a notation by the owner isn’t professional verification. The signature serves as the official attestation that the service was completed or the inspection was performed by a qualified person.
