D.O.T Renames Bottle Exemptions to Special Permits

The division within the Federal Government Department of Transportation that oversees hazardous materials-The Department of Pipeline and Hazardous Materials Safety Administration (PHMSA-what a mouthful)-has revamped the exemption codes that are used to describe the standards under which various pressure vessels (tanks) are manufactured. Those standards include materials used, method of manufacture, restrictions on the materials stored within the vessels, usable working life and re-testing requirements for re-certification.
In other words, the names used on an air tank that tell you when you need to get it hydroed (and how many times it can be hydroed), have been changed.
Paintballers are no doubt familiar with the 3AL, 3E, 311005 and other designations used on both CO2 and HPA/nitrogen systems. These designations are still in use for bottles that are manufactured under the old "exemption code" system and will remain valid for the usable lifetime of those systems. Newly manufactured bottles will now come with an "SP" -for Special Permits -designation.
This changeover may have confused some individuals who were attempting to use the HAZMAT.GOV website to look up exemption codes, since the old page listing those codes in sequential order has been replaced by a new page listing SP designations, and no conversion or additional lookup help is provided on the site.
Although it has not been specifically verified by PHMSA Special Permit Specialists (that�s their title), it seems that in many cases the letter designation (such as 'E') in an exemption code has simply been switched for "SP". A search for the 3E1800 exemption code was successfully concluded by simply placing "SP" in front of the original exemption code in the search box ("SP 3E1800").
Exemption Codes and Special Permits can be found at HTTP://HAZMAT.DOT.GOV,
In related news: there does not appear to be any connection between this branch of the Federal Government and Smart Parts Inc, despite the shared use of the abbreviation 'SP'.

The first one was a result of oil getting on the asa and fill nipple and when it was screwed into the marker the TANK exploded resulting in some pretty serious burns and some shratnel that almost hit bystandards....the most recent indicent happend in the UK although it was with a pro team and a guy who was playing for about 20 years...
He says there was no way that their was oil in the tank...its still unclear if it was reg seperation or the tank exploding but he wasnt hurt...his jeresy was pretty bad though...its being investigated and a report will be made about what exactly happend.
Both of these incidents were tanks made by stacko...at least thats what ive been told I havent read any formal reports yet.

If it was a co2 tank I can almost guarantee that it was an older tank with a faulty or no burstdisk and it got too hot.

For those that don't know, Stako tanks are Carbon Fiber tanks with no metal lining. It's just the Carbon Fiber.
In the first issue, a small section of the Carbon Fiber had been weakened due to heavy use, and air actually began to leak from the body of the tank. The leak continued (unknown to the user). Eventually the damaged section gave out, and the tank more or less "exploded". I believe this is the incident with the Pro Player.
The second one was just oil in the wrong spot, and we all know what that means. (For those that don't, it means 'BOOM! Fire! Possible Injury or Death!')
As for the CO2 tank, if it's the story I think you're referring too (where it busted a whole in the wall and almost hit the mother), that was user error/stupidity. In the news video I saw of this, the tank WAS SITTING BY A HEATER! 4 out of 5 Dentists agree, that was a dumb move. Second error was the wrong burst disk was in the tank. I believe the tank had a 5000psi Burst Disk (for 4500 HPA tanks). CO2 tanks need something like 1500 PSI (correct me if I'm wrong. I don't work on tanks any). Thus when the tank reached it's pressure limit, the burst disk was still well under it's limit, and the tank gave way.
As to why the Feds have changed the code around, I don't know. But they better re-change it, cause Smart Parts is gonna sue their butt as soon as they see that new code lettering.
