What date information must be included on yellow tags?

• A. Year only
• B. Day, month, and year (to be punched)
• C. Month and year
• D. Day only

Answer: (B)

Precise dating on service tags is essential. The date information on yellow tags must include the day, month, and year and be punched into the tag. This provides an exact timestamp of when the inspection or hydrostatic test was completed, which is crucial for checking when the next inspection is due and for keeping a verifiable maintenance history. Having all three elements avoids ambiguity—year alone doesn’t tell you when in the year, and month-and-year or day-only don’t specify the exact day of the service. The punching ensures the date is clearly recorded and difficult to alter, making the tag a reliable record during inspections and audits.
