What does each MRC completed with a tag out flag contain in the check note?

Each Maintenance Requirement Card (MRC) completed with a tag out flag must contain the tagout serial number in the check note. This is crucial as it ensures proper tracking and accountability of the maintenance being performed. The tagout serial number links the maintenance activity to the specific tagout that was put in place, which is essential for ensuring safety and compliance during maintenance operations.

The inclusion of the tagout serial number allows for clear communication among personnel regarding what specific equipment or systems were tagged out, reducing the risk of mishaps that could occur if maintenance is performed on equipment that is still active or in use. This practice reinforces the importance of adhering to the tag-out process, as mandated by safety and maintenance procedures outlined in the 3-M Manual.
