Emergency O2 tank needs hydro...

[StreetDoctor]

I have about 10 tanks from my grandmother before she passed away. They've been in a closet for the last 8 years and are all out of hydro. I called one LDS and they said they can't hydro it. Any idea where I can have this done? I'd love to bring it with in case of an emergency.

I can get them hydro'ed. I just had 2 last month.

Check with a local O2/medical supply company?

It shouldn't be a problem but I wouldn't count on a dive shop to be on top of it, especially one not dealing with O2 / Nitrox.

Just bring them to an industrial gas or fire extinguisher service center. If that shop does not do onsite hydro they will know a local resource.

They can hydro them. There is nothing special about hydro-ing an O2 tank. In the hydro test, they remove the valve and attach the tank to a "pipe" that fills the tank with plain water under pressure, while the tank is in a bath of plain water. Then they measure how close to the original dimensions the tank returns to when the pressure is released. You might have to have the tanks oxygen cleaned afterward. The valves probably need servicing, as well. You will have to check with the manufacturer, or perhaps a local safety equipment dealer, to find out where to service the valves. Actually, if you have a local safety equipment dealer you can just ask them to send the tank in for hydro. Check your local phone book for "Praxair". Or go to www.dexknows.com and do a search for "Safety Equipment and Clothing" for your local area.

Most times those medical oxygen cylinders are just swapped out for a full tank and you just pay for the oxygen. I own a argon cylinder and when it is empty I just return it they swap it for a full one, no worry about hydro's

What the Captain says is true. What you have is a "Lost tank" there are many from just the situation you have. The insurance company paid for it years ago and the medical O2 company should just put them back into rotation and give you credit in their system for them.

What they may do is try to put you on a lease, don't let them, they make more money off of the lease then from the gas. Go in without the tanks and ask if they will take the tanks and give you credit. They may only give you credit for one or two for all the tanks you will be dropping off, but that is all you need.
