Who must be qualified and certified to sign off a Red symbol entry for a specific maintenance task?

The requirement for someone to sign off a Red symbol entry for a specific maintenance task is that they must be qualified and certified personnel. This classification ensures that only individuals who have undergone the necessary training and have demonstrated a comprehensive understanding of the maintenance procedures and safety standards are allowed to validate that a task has been completed satisfactorily.
