What he said! Make sure you have a low opening (CO2 is
heavier than O2) for the CO2 to escape out of. In paintball
shops, they have a line for venting the bottles (you have to
chill them to get liquid into them) which has a muffler on it and
is located near a door. Well, if they know what they are doing,
Be careful with the cold. Since CO2 is in liquid form in the
bottle, it can be a lot colder coming out due to a full state
change. You can get localized frostbite and possibly do
temperatature damage to delicate components.
Depending on what the nitrogen cylinders are rated at,
they may have liquid in them as well, and the same cautions
(See what I learned at OSHA-mandated "hazardous materials
training" for high pressure vessel handling? Aka, "paintball class".)
