wysmar:Ouch! Over a month w/o your tanks?!?
How long does it really take to get thanks inspected? Maybe the demand isn't as high there as it is here in FL.
I got mine back within a week.

jscott099:Well Mike, after cleaning the tank, I can just slap the sticker on it and assume its clean. Or I can check it again. Which would you prefer? And yes there is a way to verify the presence of hydrocarbons and that is with the black light lamp that I referred to. Those things cost money and I'm not doing it for the fun of it. The nitrox visual takes me longer and costs me more in tools. I didn't say that I charged extra for the clean work area. But I do take the extra time to throughly re-clean any tools that might come in contact with the tank. I like my customers to know that I go the extra mile to ensure their safety as well as the air filler. Three extra bucks, wow. You don't have to pay extra if you don't want to. Find someone who will take the easy way out. Just remember, its the air filler who gets killed by the explosion.
oxyhacker:I'm confused. Most shops don't charge extra for a nitrox-clean visual since they have already charged the customer for cleaning and figure that charge includes any extra inspecting it needs.
In your earlier post you seem to be saying that you will certify a tank as PP/O2 clean on the basis of a visual and blacklight inspection, without having cleaned it. Please say it isn't so!
jscott099:In either case CGA G-4.1 Cleaning Equipment for Oxygen Service, allows the use of a fluorescent wand of bulbs that emits black, long wave ultraviolet light with wave lengths between 320 & 380 n m to determine if sufficient contaminants exists to require cleaning.
jscott099:I'm not interested in a pissing contest here. But CGA G-4.1 is up to date as Feb 2004. What tech agencies are you talking about? When it comes to cleaning and inspection for oxygen service this is the defacto standard for ANY compressed gas cylinder that may contain pure oxygen. Various tank inspection cert groups (PSI is the one I am certified with) use CGA G-4.1 as the guideline. Tank manufacturers also use 4.1 as the guide for denoting when (or if) they clean their tanks before shipping.
Look in the Scope section of CGA G-4.1 - it states that "equipment and systems handling any gas in excess of 23.5% xygen by volume shall be designed as if that equipment and system is handling oxygen."
