how safe is paintball co2?

I want to try to set up a paintball co2 tank but on the warning signs it says that it can kill someone and all that.

No more dangerous than any other co2 system used on an aquarium. co2 in itself is a pretty safe gas; and is most often used in fire extinguishers. So long as you dont try to modify it in any crazy way and get all the required components/do the required research you should be good to go. Probably worth pointing out that if you have a large aquarium you'll likely be looking to upgrade to a better/bigger co2 system if you use it for any length of time though.

Also be sure to strap the tank if you put a heavy regulator on top of it.

Good point! The only "danger" there is ruining the system when it falls over from being top heavy and ends up breaking a connection, the regulator, the gauges, etc.

If you are using one of the $40 dollar systems it is not always very consistent. If you have one with a nice regulator and needle valve I would say it is just like any other system just a slightly different tank.

Yup strapping in is a great point. A big danger for any cylinder is tipping over, puncturing and turning into a missile. Also keeping it away from sources of heat. Safety first!!!

It's not the CO2 that is the problem in a paintball CO2 setup; it's the fact that the pressure is entirely unregulated. The danger is that if there is a blockage downstream, it will eventually pressurize the entire system to ~700 psi, which definitely could lead to metal parts flying around when it all comes apart.

Could a regulator fail and allow full tank pressure out? Absolutely, but it is designed specifically to prevent that.

The problem with consistency is that a lack of it can gas your tank and kill everything, whether it's a couple of valves causing the problem or a cheap regulator.

There are plenty of things in your home more dangerous than a paintball CO2 cylinder..

That said, they are compressed gas cylinders, and even though the pressure is modest compared to many other gasses, they should be given some reasonable respect. They are still considerably higher pressure than common aerosol spray cans or propane bottles in your home/workshop/grill (which can also do bad things if abused).

Don't do stupid things like hit a CO2 tank with a sledgehammer, toss it into a fire, or shoot it with a rifle. You can find youtube videos of these things, which should give you some respect for how they fail when abused.

Keep in minde these are examples of how they fail when abused badly.. CO2 tanks are designed to be rugged enough to handle mild drops, tips, and falls without failing. Let's face it, paintballers go running around carrying these while dodging behind obstacles, putting them through lots of mild abuse... They can, and do, fail sometimes, but this is rare. Even more rarely they kill someone, as they can go flying with impressive speed...

A more typical problem is the safety release going off after the tank is over pressurized, which can give you some frostbite and may drive you out of the room, but isn't going to inflict major injuries:

how does a tank become over pressurized? and safety release is suppose to throw out all the pressure if its too much right?
