Final answer:
A maintenance person validates an MRC card by verifying that maintenance tasks have been completed, and then signing and dating the card to confirm completion. This may also involve a supervisor's confirmation, and regular audits using a periodic report.
Step-by-step explanation:
When a maintenance person needs to validate an Maintenance Requirement Card (MRC), they usually follow a set of standard procedures to ensure that maintenance tasks are completed accurately and in compliance with regulations. Typically, the validation process would involve verifying that all steps of the maintenance task have been completed as per the MRC. After completion, the person validating the card would usually Verify completion with a signature, which serves as a record of who performed the maintenance and when it was done. This involves signing and dating the MRC card, thus accepting responsibility for the work. Depending on the organization's protocols, the maintenance person might also need to Check with the supervisor to confirm that the work has been done satisfactorily before signing off on the card. Some systems may also use a 13 week report or equivalent periodic review document to track and audit the completion of maintenance tasks over a significant period.
