When a job needs another review, place a clear hold note beside its job card before moving to the next task. The note should state what is unresolved and prevent a later person from treating an open question as approval. Follow applicable instructions and use protective eyewear, shielding, ventilation, and attended operation.
Make restarting deliberate
Return to the hold note before resuming work and replace it only when the question has a documented answer. A visible pause supports a careful shared workspace.
