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.

Did I somehow miss all the posts on this or is he refering to the people that messed up with installing the Anti-Syphon tubes?

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.

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. (Navy firefighter training)

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/S tore/en/-/USD/DisplayProductInformation-Start;sid=I93_BeHwFM T_CKL77Ec_retWhp1K2XryTU4=?ProductID=vozAqArbSqUAAAECVbkmO6L C

I think that story would be BS,

The valve would not shoot through a person.

Shens.

So you say a tank can go through a concrete wall...but a valve can't go through a person? What is this? Lets believe what ever BS The Guy feeds us.

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.

I will be the first to admit my faults. And so I admit that I actually never thought of that.

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

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.

it's possible it could hit the person filling or someone standing near, correct?
