I was at our local field on July 30th. They Recently came out with a new policy about removing tanks. Now only a Ref can remove your tank. The Reason Why, They said that two people were killed when people were removing there own tanks (In california). They said that when you went to remove the tank, the Tank would screw out the valve on cheaper, not well made tanks. Thus, the tank would launch off the back of the gun and fire off like a rocket. Something they suggested was take white out and place it in a straight line from the valve to the neck of the tank. If you go to remove the tank and notice the line breaks, stop and take a wrench and remove the tank from the valve. Im not sure if this is true or not but thought it was worth posting. ------------- =============== SARGE A-5 (Stock) |

painting a line on your valve is a good idea. this thread is in upgrades and customizing check it out http://www.tippmann.com/forum/wwf77a/forum_posts.asp?TID=88603&PN=1 - http://www.tippmann.com/forum/wwf77a/forum_posts.asp?TID=886 03&PN=1 ------------- http://img76.imageshack.us/my.php?image=stickemup6of.jpg">

People are making this a lot more complicated than they really should. The threaded part of the valve that goes into the tank is like an inch long. Just be aware of what you are doing when you are taking your tank off. If you notice that your burst disk isn't turning, then something is not going quite right.
I'm not saying that it is a bad idea to put lines on your tanks/valves, but there are many solutions. One is just paying attention. A second is just how easy it is to turn. If you take your tank off properly, it should turn effortlessly. When you unscrew it 3/4 of a turn and shoot out the CO2 in the gun (or turn off the on/off and shoot) there is no resistance to turning your tank. And if either of those ideas aren't good enough, check these out. I just saw one for the first time today. http://www.countypaintball.com/product_description.asp?item=1071 - http://www.countypaintball.com/product_description.asp?item= 1071 -------------

What the hell? So if your tank is unscrewing from the valve (bad) you take a wrench and help it along its journey to becoming a missle? Did you mistype or is someone just dumb? -------------

jus unscrew it with it aiming down or in a safe direction ------------- i lost my strike.. good things do happen to bad people |

I am fairly confident that he knows better then that. It is VERY common for people to call the ASA the valve. You know what...there are far better ways to correct people then being an ********. -------------

Yeah, what i ment was take a wrench to the burst disk to get it out of the ASA. I was quite sleepy when i wrote the post to begin with so, when im refering to valve, i mean the burst disk. My Bad. ------------- =============== SARGE A-5 (Stock) |

He is just a little unclear. Take that wrench and unscrew the tank valve from the ASA (valve). There are no flats on the neck of the tank that would allow you to use the wrench on it. Most of the tank valves these days have a spit hole part way down the threads so that if a valve screws part way out of the tank it vents out the side (sort of like the pressure disk blow out) emptying the tank before completely unscrewed. These deaths took place several years ago and most valves are modified to reduce the likelihood of such unscrewing launching a missile. Just look at the neck of the tank as you are screwing it out of the ASA to assure it is cot coming out of the tank. |

Absolutly wrong guys. Take no chances, if the tank begins unscrewing. Immediatly drain your tank. It needs to be emptied to be worked on anyway. Either remove your burst disc, or press forward on your bolt to open the gun valve. ------------- http://www.anomationanodizing.com - My Site

unscrew a burst disc from a pressurized CO2 tank. the whole idea is NOT to propel objects from a defective tank, and you want us to unscrew one of the two things that can fly off in a potentially dangerous manner????? WOW just WOW..............shakes head and walks awayPosted By: xerphiz

A burst disc is about as wide as a screw, if you're holding it with vise grips it won't fly away.
Okay, just so people have this clear, this is the way the tanks are built, and how they should be. 1. You have the ASA (that is the part of your gun that the steel braided line goes into, and that the valve of the tank screws into. 2. The metal bit which is referred to as the "valve", "nozzle" etc. (usually a different color from the tank) is screwed onto the tank at the factory, you should never remove this peice, unless you are a licensed airsmith. 3. The burst disc(s) are the little bolt looking thing(s) with 6 sides sticking out of the valve, this is a safety measure put on tanks so they will not explode if over filled. When a burst disc blows out (it has a resistance of 3000 psi, I believe, on Co2 tanks) it means the contents of the tank were at an unsafe pressure, and if the Co2 was not heated in any way, you need to make sure you are getting your tanks filled right. 4. Lastly, you have the tank, it is really just a metal bottle where the gas is actually stored. |

A burst disc will come off and go probly about 4 feet if you don't have
a hold of it. It won't take off like a tank, because the tank has the
air in it, not the burst disc.

Theguy sometimes i just dont understand you. You can be smart, and then post crazy stuff like that. Obviously the full pressure of the tank is behind the burst disc. Thats the point. Its simple to drain a tank. Spare ASA, screw it on the valve, enjoy the show. I wouldnt **edited** around with removing the burst disc assembly from a pressurized tank, thats flat out STUPID. -------------

I don't think there is a safe direction to unscrew it...if the tank comes off it will rocket everywhere, like breaking the stick off of a bottle rocket. -------------

You use a socket set when you do it. That way the burst disc just goes inside the socket when it pops loose. ------------- http://www.anomationanodizing.com - My Site

so it WOULD fly off and with enough force to take out an eye i would imagine. STILL a bad idea! ------------- http://img76.imageshack.us/my.php?image=stickemup6of.jpg">

The burst disk CAN and WILL fly off in a potential unsafe manner if you unscrew it from a pressurized tank.
If you notice your tank coming unscrewed from the valve, screw it back on. Use a wrench to remove the bottle/valve from the ASA. If you don't have a wrench handy, take the whole setup to an airsmith and explain the problem to have it removed properly. The tank should then be drained (we have tools for draining a tank safely). The valve should be removed, loctite applied to the threads, then properly replaced OR if the valve is damaged, it should be discarded and replaced with a good one. Same for the canister. If the threading is no longer in good shape, it should be discarded. Always better to be safe than sorry. ------------- http://www.EZOfficePool.com - Free NXL and NPPL Office Pools, pw: 'gogged' http://www.CountySports.com/shop/news.php - Newsletter - Coupons |

Flaming a mod shouldn't be any different from flaming a regular member... Anyway. Whoever it was who said to unscrew your burst valve it your tank isn't coming off the right way is a retard. Whoever it was who said to use a wrench to get a faulty tank off was smart. Yup. -------------

Grent, You have no concept of the power of created by opening a 3/4" hole in the end of a CO2 bottle filled with liquid. Strap it solidly to your back and it will lift you off the ground 20 feet. Lay it down on its side as the valve comes out pointed at a concrete block wall and the bottle will punch a hole in it. There are numerous safety reports of larger CO2 bottles falling over and breaking off the valve. Those bottles have punched through several buildings before coming to rest. They contain more volume, but the pressure is the same and the velocity achieved is equivalent to that of a rocket propelled grenade. You cannot hold onto a full or partially full bottle from which the valve comes unscrewed. This lack of understanding of the power and danger associated with CO2 and HPA cylinders is exactly what is fueling the calls for mandatory lecture training each time you get your bottle filled. If you get irritated by on-field chrono checks, I know you'll look forward to having to wait 15 minutes each time you go for a refill for the Ref to explain safety procedures and pressurized cylinders. |

You guys are forgetting though that he does have a some what valid point. When taking a tank off, the safest direction is with your barrel straight up in the air, so if the valve disconnects, it won't hit anything buy maybe your leg or foot. A broken foot is much better than killing the kid next to you. -------------

not quite Swat, See it wouldn't just be a quick burst of energy. That whole tank has to empty through that hole, propultion would be sustained for a decent amount of time. Most likely it MIGHT hit the ground and then take off in another direction. ------------- http://www.anomationanodizing.com - My Site

I think somebody compared it to a bottle rocket earlier... Same
thing, when you shoot a bottle rocket at the ground, it bounces off
then flies in another direction. Bottom line I guess is pay attention to what you're doing when you're taking your tank off and everything should be a-OK. If you're paying attention, the tank won't come apart like that and kill someone. -------------

This, is perhaps a little excessive. I could do the math for you, but it would be pointless. I HIGHLY doubt any C02 tank has enough force to life your average 160 or so pound man off the ground. It COULD on the other hand go flying 20 feet on its own, but theres no way it could life that much weight. I dont debate the power to kill someone, but not lift someone from the ground. |

Your way of thinking is obviously flawed. You can sit here and think about all the "could have's" and "would have's"... I am pretty sure the point of the thread is to give you the best chance of not harming yourself and everyone around you. Quite frankly, I can't think of a safer direction. But feel free to fill me in on the better place to point your tank... -------------

Out of the size hole opened up when a 20 oz valve comes out may not provide enough duration of the energy to get me off the ground, but the uncontrolled tank will go 200+ feet straight up and significantly further across the ground. BTW, some of the first rocket belts used 20 lb CO2 bottles vented through a nozzel. 20 ft altitude was easy. 250 to 400 lbs of thrust and a few seconds of flight...and then you fall from altitude.

| My pro shop stoped selling A/S tubes because he said that kids install them wrong and severly hert them selves, I need to get some for myRT, and yes im going to have them installed by some one that knows what there doing. Any clue were i can get some for cheap. I use C02 when not at my feild. |

Wasn't this the incident that happened in Sacramento? If so, then there shouldn't be anything to be worried about...A dumb*** Sportsmart person tried filling a CO2 tank, overfilled it, and apparently the burst disk didn't blow. Valve shot thru one person, and the tank thru the other. I believe it was also discovered that the dumb**** paintballer had used blue loctite on his valve... If you aren't an absolute chucklehead, then you shouldn't have to worry about a tank blowing up on you... As for the A/S tube question, Any online paintball store should have them. Here's a link to one at Action Village for $5.39: http://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/DisplayProductInformation-Start;sid=I93_BeHwFMT_CKL77Ec_retWhp1K2XryTU4=?ProductID=vozAqArbSqUAAAECVbkmO6LC - http://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/S tore/en/-/USD/DisplayProductInformation-Start;sid=I93_BeHwFM T_CKL77Ec_retWhp1K2XryTU4=?ProductID=vozAqArbSqUAAAECVbkmO6L C |

ok then, lets think about it. If a valve is unscrewed from a tank, it
will still be attached to something. Its not gonna unscrew itself just
sitting there. So the valve isn;t gonna go anywhere. ------------- http://www.anomationanodizing.com - My Site

the story mentioned above happened when filling a tank, correct me if i'm wrong but don't you use a coily hose when filling a tank? and if straightened through being propelled by runaway co2 don't you think it could hit someone standing near? ps that is a very nasty comment ------------- http://img76.imageshack.us/my.php?image=stickemup6of.jpg">

don't need a coiled hose. Any steel braided hose works. This is almost our exact fill station, we have one more valve on there though.  ------------- http://www.anomationanodizing.com - My Site
