A brand new inspection is any type of inspection or event that has not yet been recorded on the system.
A review of an existing Event / Inspection would be the second option in the screen shot below.
You would log a review if a previous inspection has already taken place, and been given a ‘Next Inspection Date’.
Each inspection on the system is part of a chain, usually with review dates. If you were to log a brand new inspection where a review is required, you would in effect be creating a second inspection chain.
