Assuming you have a standard CO2 valve, the only way it can fail is if it is overfilled and/or left in a hot car or something, and an overpressure disk will blow out. It'll probably scream like a Banshee, but there should not be any flying projectiles. At least on my CO2 tank, there is a cap over the blowout disk with 4 vent hole in it all facing different directions so the escaping CO2 doesn't propel the tank like a missile. HTH :-)
