Was considering ordering a small amount of these to do a test reaction. Lab postdoc shot down the DBO as its a shock/friction explosive, but AIBN seems to be a bit more stable. I was wondering were there any specific storage requirements for peroxide radical initiators, or is sealed under inert gas in a fridge ok?

For most people DBO would mean 1,4-Diazabicyclo[2.2.2]octane but given what else you have said I assume you are asking about Dibenzoyl peroxide. 

Note that AIBN if you mean Azobisisobutyronitrile it is not an organic peroxide but is an azo initiator.

If those are the chemicals you are asking about then yes AIBN is safer to use and store than Dibenzoyl peroxide and yes you could store small amounts in a fridge or better still a freezer. 

If you are going to use acronyms explain them.
