Oxygen Admin Kit

[joflo]

Hi Guys,

Im looking at upgrading the marinox kit to a 10litre cylinder.
The 3litre cylinders dont have a great run time.

Has anyone else done a similar thing.

thanks in advance

we are doing this at the moment to a 12L

You just need an O2 tank (any old one will do), an O2 clean first stage and two second stages. Again, any old ones will do as long as the don't go up in flames when you pressurise them. It's not like you need to worry about depth rating etc. on the boat.

The normal second stages are fine for most casualies i would say

Then you can get one or two constant feed hoses and a kit that connects a constant flow mask to them that can be used for unconscious casualties

Send a message to Woz on here, he might be able to give you a bit of a hint as he has some aquarium equipment that looks very similar to the constant flow stuff i am talking about.

As you already have the O2 kit which I assume contains both DV and constant flow on a 2 pin reg then perhaps the easiest thing would be to get a 2 pin index to DIN adapter. You can then use your existing 2 pin index regulator on an (O2 cleaned etc.) cylinder.

Get a 10 or 12 litre cylinder cleaned, filled and appropriately marked and you are good to go.

Thanks Dammyla,

We have a marinox kit which has the 2pin regulator with demand mask and constant flow.

ive seen the 300bar din to 2pin adapters floating about for £40approx.
which with abit of cleaning might just be the ticket.

then there is the question of protection..

the marinox kit is setup ready to rock and roll. i check it before we leave the dock, so in an emergency its just a matter of pulling it out of the brown tube.
and putting it on the casualty and turning it on.

if i use a normal setup and or use an adapter and use the marinox regs etc, itll be open to the elements (water/salt/knocks etc).

just trying to get a good picture of what other clubs have done and their experiences.

Its the diffrence between what can be done and what is being done.

ive also seen the rescueean pod (http://www.rescuean.diver-emergency.co.uk) which gives a constant flow from any bcd/drysuit hose. so you can use a nitrox mix when you run out of 100%. looked quite nice, but not much use if no one has got nitrox..

some good responses while i was writing my repsonse to the first one...

thanks guys..

as long as im thinking like the rest im happy.

just need to make a protective cap for the cylinder.

just need to make a protective cap for the cylinder.

Personally I would not bother. On a hard boat just make sure it is out of the way so it does not get damaged. On a rib I would leave the reg and adapter off the cylinder in something like a pelican case. Providing every thing is stowed properly you are only adding a couple of seconds to the deploy time

We have 2 Marinox cyls in the club with the standard D cyl and another 2 E size cyls we keep strapped under the bottle rack. Lots of O2.

Oh and I have my own personal old 10L ally cyl (horrible to dive with) full of O2 with a reg on it and a cylinder carrying handle. And something from an aquarium. I would not recommend doing this as something you take anywhere rough.

I would think just leave the marinox kit as is and take it as well as the 10/12 litre and adapter. Keep the adapter in the marinox kit for protection and to ensure it's there when required.


I think the main thing would be to ensure the 10/12 litre is suitably marked up - very, very clearly - and some system is in place to ensure that the cylinder and kit are always together.

we are looking at cutting the £5/month for a 3l cylinder. and using the money to convert to a higher capacity setup.

thanks for everyones help.

We went for an old 9L cylinder, cleaned it, put a two pin valve on it and consider that job done....

[TrevorB]

What do you all do about service, the O2 cylinders need testing every 5 years

If you adapt a scuba cylinder then it will need an O2 clean every 12 months
or am being naive and you don't bother unless it needs filling

[bythesea]

you don't bother unless it needs filling

There is your answer...

Use a peli-type case for the reg/mask or continue to use the marinox kit and just fill the gap left by the clinder with a decent 1st aid kit, space blanket, picnic rug, etc.

We've got Two Marinox kits, a third kit in a pelican case that are for use, a forth kit is only used for training.

The three kits that are issued on trips also have a Two pin to DIN adapter, & a Bullnose adapter to Two pin adapter in each kit.

There is always 1 D cylinder, sometimes 2. We also normally have a lot of Deco gas & often additional Oxygen cylinders. It is all dependent on where & what we are doing.

The Bullnose connectors mean we can use J cylinders, or some of the other sizes of commercial cylinders. (We have been known to bring our own :)).
The DIN adapter means we can use O2 from rebreathers, Decompression gas, or even diving nitrox if it comes to that.
