  I talked to a customer about such things a couple years ago.  Turned out 
he knew his refrigerants and hydrocarbons quite well.  He contended that 
propane not only would do about as good as propane, it was much more 
safe than any would think.  Propane is really fussy about the air:fuel 
ratio.  Much moreso than gasoline.  He said the odds of a leak igniting 
were slim to none.  Odds are that it'd either be too rich or too lean, then 
with open air it'd dispurse quickly.  Been thinking of trying it on the 
Actually did try it once.  That's when I found a hose had worn through.  
Good thing I didn't dump any $50/lb R-12 in there!
