in_cavediver:According to the CGA and DOT in the US, Visuals are only required with hydro every 5 years and that is by CGA/DOT guidelines and done by the certified hydro tech. The annual VIP stuff is a dive shop/dive industry thing and is *not* required by law. Seeing as how the inspection is not required by any law, how is liability increased? Isn't the defense simply "My tank met *ALL* CGA standards and is proven with the current hydro stamp". Since there isn't any other recognized standard, what standard can be used to compare it to?
Now here is a fun game to play. Take a cylinder that has a hydro stamp that is less than one year but NO visual sticker into your local shop. I bet more times than not the shop will refuse to fill the cylinder cause it does have the "magic" sticker on it. As part of the hydro cylinders are given a visual. And the CGA standards they follow are the same ones that PSI and others follow. So the hydro stamp is the visual for the first year.
As for the hydro - they are required in commerce. No commerce no requirement. For instance, the storage bank at our university is a set of cylinders that I have been told date from the 50s (No one gets down there unless needed). They have never been hydro'd since they were installed.
The VIPs are an industry "practice". But the practice seems pretty loose to me. By that I mean who is doing them and to what standard. It is my understanding that at this point the only inspection program that is mentioned in the CGA regs is PSI's program. That is not to say it is the only program that should be as I am sure there are others that are just as rigorous but this is the program I am most familar with.
I do my own inspections as well as for my friends. I started because of the cost and after I how saw they were done. My old shop used to charge a minimal $5 for an AL cylinder. But after they closed down it was then $15 at anther shop. With 4-6 cylinders a year it got expensive.
I can understand other shop questioning "generic" VIP stickers as the scuba industry had kinda screwed themselves.
