As I recall there have been a few people die during their OW certification process. Possibly a search in the accidents forum will give some results.
Having a Spare Air would only be of use IF you were proficiently trained in its use, which is something that is not going to happen in an OW course. The situations where ther were deaths involved problems that were beyond the capabilities of a Spare Air.
One death I seem to recall was a drowning stemming from an entanglement after becoming seperated from the group while diving in low visibility.
There are so many better things to focus on learning than a Spare Air. Refer back to the post by JimLap for the purpose of a Spare Air.
