royalediver:CGA rule (3.1.1) which list 29 CFR 1910.1200(f) (9) states
"the labels applied by the gas supplier to identify the conatiner contents shall not be defaced or removed by the user until the cylinder is empty with the provisions of 29 CFR 1910.1200(f)(9)
Putting a nitrox label is prudent. If you fell off the planet tomorrow most would assume air is in the tank. The risk is not to you but for those who follow. There are volumes of CGA/DOT documents to back up the stores request to label the cylinder.
I don't blame them for that. The liability laws in this country are just absurd.hlsooner:The issue was whether one of the large NITROX-ENRICHED AIR stickers was mandatory to idiot-proof the tank. My understanding is that they are not, but as some have pointed out in this thread, if the filler is concerned about liability then they may choose to fill based only on their individual requirements.
hlsooner:Just wanted to post a problematic encounter I had last weekend.
A couple of months ago, I purchased some Worthington tanks from Fill Express. The tanks have a nice green VIP sticker that clearly states they are clean for oxygen service. But Fill Express recommends against sticking other large NITROX stickers on the tanks to prevent corrosion. Furthermore, these large stickers are not required, and actually don't do any good to prevent the wrong tank being filled since anyone can buy these nitrox bumper stickers at a dive shop and put them on any tank.
Last weekend I needed to obtain fills before going out on a trip in Miami. I did not have time to get gas at Fill Express, so I went to the dive shop that ran the boat I was going out on. As I walk in, the employee who was filling nitrox tanks asked if I needed air. The following exchange ensued:
Me: I need to get some nitrox in my tanks (note small stickers were still on them indicating previous fill was 32%)
Employee: I can't put nitrox in those tanks, they don't have a nitrox sticker, as he points to the large bumper stickers he has for sale.
Me: You don't need one of those stickers for nitrox, besides, this VIP clearly states these tanks are oxygen clean.
Employee: I don't care what that little sticker says, I am not putting nitrox in those tanks without one of these (pointing to bumper stickers) on your tank.
Me: Well Fill Express, the premiere technical diving gas filler in the area has no problem putting nitrox in these tanks.
Employee: Well they obviously don't know what they are doing.
Me: Okay, if your air is nitrox clean, then just give me air (smiling and realizing this is going nowhere)
How can a person be allowed to fill tanks with nitrox and have no clue what a VIP sticker means?
hlsooner:I don't want to name the shop, since I know the owners and they should not be smeared for the actions of one less than knowledgeable employee. Let's just say a shop on Miami Beach.
ekewaka:The liability laws in this country are just absurd.
The VIP sticker may be enough to tell you and the owner of the tank that it may not contain air, but is it sufficient labeling to prevent the inadvertant use of the tank by a diver that has OW certification and nothing else?Scared Silly:. I can see there being different interpertation of the CGA rules. But I would say that any cylinder with a Nitrox/O2 clean VIP is enough in my book to know that the cylinder may not contain air.

Anyone who uses my uses my tanks without my permission deserves to oxtox and drown.Charlie99:The intent of the bumper sticker is to be obvious enough that there is negligible chance of it being erroneously used by another diver that thinks it is air.

The intent of the bumper sticker is to be obvious enough that there is negligible chance of it being erroneously used by another diver that thinks it is air. When you think of the bumper stickers as performing this function, then it makes sense that many fill operations require bumper stickers on single tanks, but don't require them on a double set.
