If you don't want content reviewers to accidentally modify your document, you can make the document read only before sending it for review. Another method is to restrict formatting and editing.
Making your document a read-only file means that the document can be read or copied but not modified. If one of the reviewers tries to make changes to a read-only file, the changes can be saved only by giving the document a new name or saved to a new location.
Note: Making your document read only doesn't prevent someone from making a new copy of the document and saving it with a different name or in a different place.
