See Safety tabs.
Additionally, this tab has a Remove Duplicates button. When you click this button, the system will remove all duplicate combinations of a hazard, precaution, and timing, leaving only one remaining unique combination of each. If duplicates are found the system first removes the rows where the revision of the hazard or precaution is not the most recent present on the screen. If this is not sufficient, the system then removes the older duplicates, keeping the most recently updated or created record. If still not sufficient, the system then removes the records randomly giving preference to records with a lower Sequence number. The Source Type, Source Code, and Source Org. of the remaining record will be cleared by the process. Documents and Comments associated with the deleted duplicates will be preserved on the remaining record.
