As the use of life extended SCBA's increases in the fire fighting, first responder and PCP worlds, NIOSH is looking to make a position statement. This primarily will deal with the use of life extended SCBA's used in NIOSH approved SCBA packs. If you want some interesting reading on the subject...

For that same price you can buy a DOT rated life extended bottle from Pyramyd Air Pyramyd Link

If you are interested in a very detailed study on carbon SCBA's, go to the Department of Transportation(DOT) web page at the following link: DOT SCBA Study When you are at this page, you can download the study report. There is a link on the right side of this page to download the report. ...

I do not believe they have a DOT Special Permit number. Hence they would not be sold or allowed in the USA. At least to be transported in commerce. I may be wrong, but I would be surprised that it was truly a 3 piece design operating at this pressure. The black caps on either end are most...


The trade in is a great idea. We actually offer that on the fire SCBA side. Departments though seem to want their own ones back we have found rather than a swap out. But who knows in the future. Our drive is to get the best product out and don’t want to rush anything. Thanks again! 

Tominco - you emailed in asking about this. I updated a different thread with the following: Currently Digital Wave is looking at adding that option for airgun owners. Life extension is a bit more complicated process than just a quick hydro test. Also, how do they handle cylinders that might...

Yes, many of you have asked and called about being able to send in your own out of date cylinders. Currently Digital Wave is looking at adding that option for airgun owners. Life extension is a bit more complicated process than just a quick hydro test. Also, how do they handle cylinders that...


Yes, I as well would like to hear about where you received your SP16320 stamped cylinders allowing 30 years use under DOT regulations. Those sound pretty cool.

Every tank you have has SP-16320 on it? So you own life extended tanks? Where did you get them?

Note: 15 year SCBA's are now allowed to go to 30 years in the USA per the DOT: https://www.phmsa.dot.gov/news/phmsas-new-cylinder-special-permit-maintains-safety-standards-while-offering-cost-savings-first Below is the DOT SP-16320 that allows this...

If you want to see and SCBA burst, watch the following video(jump to the 6:40 mark where it is close to rupture): SCBA's can now be life extended past 15 years of use. See following DOT link regarding this approval...

Did he say why they were taking them out of service? Is it because they are 15 years old? These SCBA and other carbon fiber vessels can only be used for 15 years. However, they can be life extended to 30 years of use from the original manufacture date. This life extension option is a...

Just so you know a bit more about these tanks, the US DOT must authorize their use in the USA in order to transport or fill them. They do this via issuing a Special Permit(SP) number to the tank manufacturer. As someone mentioned above Luxfer, SCI and also Carlton are the primary manufacturers...

Note - this particular cylinder will have a funky valve as these were used to inflate life rafts. It will not be the standard SCBA valve you have seen before.


Patpat7 - yes this one is applicable. You will see in the upper left corner "DOT E-11194". This is the Special Permit Exemption number that this cylinder was built to by Carleton. On the digital wave life extension page you will see this SP number listed. Other things to look at on this...

Digital Wave will life extend your end of life SCBA for $250 + return shipping. They will need to remove valve, perform CGA visual inspection, MAE life extension test, relabel, will add new fiberglass sacrificial protective layer, reinstall valve and ship back. This service is only for carbon...

More info on how these CFFC (carbon filemant fully-wrapped container)/SCBA vessels used came about and how durable they are: http://media.wix.com/ugd/d00b78_72625b919876457fb9191418c1259c6b.pdf

Look at Digital Wave Corporation web page under MOdal Acoustic Emission MAE and you will find more. This technology is based in broadband acoustics and not X-ray(RT) like someone said above. The DOT does not allow RT examination for this. DWC holds the DOT special permit and have the RIN...
