Thx for the post i think im gunna paint a line on the joint incase the tank where to ever come undone. I whink thats a good habit to do to your Co2 tanks especially if u do things like take tanks apart at home you never know when something like this can happen everyone should be aware that paintball is dangerous and paintball markers are not just toys.

the 2 deaths were caused by a modification (putting the anti-siphon in). but there is also a recall on some tanks too.  historicaly the department of transportation did not require thread locking compound, but they did have a high torque requirement for the tanks. after these acidents some of the manufacuers of co2 tanks put a memo on there sites with the tanks that were being recalled due to no thread locking compound. most of the recalls were tanks that do not have a "rehydor test" sticker on them. i do not know the year that some of these companys started puting locktite on there tanks but it has never been a mandatory thing. so for those companys they issued a warning for some of there old tanks to be hydrotested and some of there newer ones to be recalled.

looks like a few guys are still thinking the anti-siphon itself caused the accident. sounds to me like it was an improper installation. the anti-siphon tubes are perfectly safe if installed correctly. I just want to point out that just because a shop does it dont get careless. shops dont always do it right. I always ask to watch when a shop does a quick job like that. I have an old gun that runs on liquid & had to have a siphon tube installed in a tank. the guy didnt use loc tite & just snugged the valve on. I had to call the manager over after the guy argued with me about it. was glad I watched him or it could have been really bad. back in 1988 I was at a field & their fill station fell over & knocked the valve off the fill tank...sounded like a rocket going through the woods, bouncing off trees.

  I feel bad for the families of the victims.  I just wonder how many close calls of this same type have happened that didn't hurt anyone?
Just the thought of one of my 20 Oz. tanks taking off like that makes me cringe.  That would tighten up the old butt cheeks real good!

Just to let everyone know New tanks CAN unscrew at the valve. I know, I work for a local sporting goods store were I sale paintball guns, co2 tanks as well as fill them. I sold this guy a new tank and 2 days later he came back and told me about his tank coming apart at the valve. Last week I RTV 2 more tanks because of this problem. The tanks I have had a problem with have been the 20 oz Java tanks, that we no longer carry. So watch out even if you have a new tank whatever the size is or make.

If it moves... Shoot it!!

The valve may unscrew from the tank,    if it does a full tank will take off like a rocket... two bystanders have been killed.

If you mod your tank, use locktite when you reassemble, and mark it so you can easily tell if it's unscrewing.

wow so how will we know if our valve is coming off? if it was, is it a gradual process and then one day it comes right off? or is everything about your tank gonna be great until one day BOOM?

Paint a line accross the valve and the tank, if it ever becomes missaligned, you know it's worked loose.

To answer D-ballz question, an anti siphon is just a straw that goes fromt he valve of your tank (inside it from the front) pretty much to the back of it (inside).  Without anti-siphon tube anything can be let out of the front valve.  With an anti-siphon in, the tube (really just a straw) stays in the back middle of the tank. This makes it so that only gas CO2 can be pushed out of the tank, in theory. 

Another example:

If you use a remote line, all the liquid CO2 will pool at the bottom of the tank and the anti-siphon straw will be submerged in it.  This will make the tank a siphon tank and you will only get liquid out of the tank for the most part.

Feel free to correct me if I'm wrong.

You are close. The straw in an anti-syphon is actually curved back to point towards the valve. It is important that the tank be set up for the individual marker so that it will curve and further out of the liquid. In this way a remote line will work fine, though in general remote lines have trouble with anti-syphon tubes because the users occasionally lay down. However, the remote line itself usually lets the liquid expand into a gas somewhat anyway.

The straw pointing down is actually a syphon tube. It can be either a stiff copper tube like the anti-syphon or a flexible tube with a weight on the end (the second is actually more effective). Why would someone want that? Because they want to feed liquid CO2 into their marker. And no, that is not always a bad thing. Actually, Tippmann SMG-60/68 and 68-Specials need liquid CO2 to maintain a high RoF and were designed for this. Additionally, pump markers don't particularly care and may actually have better performance in cold weather if using liquid CO2. Yes, I did say better performance.
