accident waiting to happen

[joens]

you are right on several points the OSHA guideline is somewhat vague and the SCUBA style sticker [as far as I know ] is used just by scuba and scba . however OSHA refers to the CGA ro guidelines fir inspections and The compressed gas association publishes guidelines for vis inspections that are similar to what a proper SCUBA VIS is but they dont use the stickers we do .I dont think a sticker would stay on a acetylene bottle long. I did see a sticker on one once that looked like the paper that you get in your new jacket [inspected by 7] .

... is under DOT law.... the al or steel tanks need 5 year hydrostatic testing.

Here's the other thing when dealing with paintball cylinders. I don't know if there's a cutoff on the small sized composite cylinders, but in the fire industry the composite wrapped SCBA cylinders get hydroed every 3 years. How many paintball players do this, I don't know, but I think some if not all their composite cylinders fall under this same law.

has to do with the composite cylinders.

There is now apparently a Luxfer "wrapped" cylinder available for scuba use that has the same kind of limitation.

Composite Cylinders have a 15 year life. Must be decomissioned after that, and you can't get it re-hydroed past that point.

One more thing - aparently some composites have been extended to only need hydros every 5 years instead of 3... (I was doing a google search on this subject and found the following:

For those not familiar, Scott is probably the biggest manufacturer of SCBA for fire depts.)
