Silicone tube is definately not what you want !

It can withstand high temperatures. THe whole point is to have a really low
melting point so the tube melts at the earliest possible time and allows
the
CO2 to flood the area.

Point to note here,

You've got to consider the wirst case scenario, of having a presurised
cylinder in a fire.

Other than that, CO2 for welding is easy enought to come across, along
with regulators, couple this to some silicon tube and your 90% of the
way there.
