This is similar to a question on using converted SCUBA tanks last year.
I've never seen any rules regarding these, but personally, I wouldn't want a
high-pressure bottle laying around in the paddock, especially in the bright
sun. Sure, they can be dropped, but I've seen a SCUBA tank turn into rocket
projectile when some clod dropped it at the wrong angle and knocked the
valve off. Why take the chance?

Is it that much trouble to fill the thing before events? IMO, if you need
more air than a low-pressure tank provides, buy a good portable compressor.
