2.7.5-1 User Confirmation of Destructive Entries

When a control entry will cause any extensive change in stored information, procedures, and/or system operation, and particularly if that change cannot be easily reversed, the user should be notified and confirmation of the action should be required before implementing it.

Additional Information:
What constitutes "potentially destructive" requires definition in the context of each system operation. When user entries or changes will be nullified by an abort action, the user should be requested to confirm the abort. Confirmation messages should be simple, positive, and direct.
