Which procedure should be followed for equipment with inaccurate or missing data plates?

• A. Assessment procedures on such equipment
• B. Immediate replacement of the equipment
• C. No action; document as is
• D. Return to vendor

Answer: (A)

When equipment has an inaccurate or missing data plate, the first and best step is to carry out assessment procedures to determine its safety, compatibility, and remaining life. The data plate carries essential information—such as material, size or model, allowable pressures and temperatures, and service conditions—that tells you how the equipment was designed to be used and what inspections or maintenance it requires. Without reliable data, you can’t safely rely on standard operating or inspection procedures. Conducting an assessment involves verifying dimensions and markings, cross-checking with drawings, purchase records, and any available vendor specifications, and possibly performing non-destructive tests or inspections to gauge current condition. The results of this assessment guide what to do next, such as obtaining correct data from the manufacturer, re-tagging with verified information, repairing or replacing parts, or deciding not to use the equipment.

Replacing immediately is not always necessary or practical, and doing nothing is unsafe because you’d be operating without verified service limits. Returning to the vendor can be appropriate later, but only after you’ve performed an assessment and gathered the necessary information to justify the action.
