No; the oxidizer based explosive mixtures they're talking about are 
oxidizer/carbon mixes commonly used in mining.  Carbon black and LOX is a 
common mixture.  Needless to say, do not try this at home; it's flippin' 
dangerous.  ATF regulation of such mixtures is quite proper.

Nothing wrong with having LOX.  You should comply with the applicable OSHA 
regulations, which are easy to find and even easier to meet (if you avoid 
doing anything obviously stupid, you will find yourself OSHA-compliant) 
(Matter of fact, they're so easy to find, I did it for 
you.  :-)

Transporting gaseous oxygen and transporting LOX both have risks, and 
regulations; which is more appropriate for you depends on your organization.
