Freon tanks have a "blowout disc" that ruptures at something
approaching 600PSI. A freon tank is likely safer than a lot of cheap
"air pigs" designed to operate at 120PSI . painting the interior to
protect against moisture MIGHT be a good idea (on the air pig too - -

How would a 20 lb propane cylinder compare? It's getting hard to
have them requalified in my area....
