We'll be getting our grubby little hands on you shortly Mathias!

The time will fly by!

See you soon,

Dave.

Hey Mathias,

Your boris is feeling lonely in its box and dying to get wet again

You'll be the lucky one since the water will be warmer by then, OK I know you are use to these conditions as well.

Looking forward to see you in may.

Cheers,

Hi Fred!

I've finally stopped eating Pizza! Maybe in France next time. You can talk in French, while I will point wildly and shout loudly in English; as is our way

Dive safe mon ami,

Martin

Michael,

Nobody is breathing 3.0 bar they come straight off the loop, and in any case it wasn't 3.0 bar it was 3.5!

It's called real world training, for the real world. It is what can happen if an orifice or a solenoid fails open, in a matter of seconds you have 100% O2 in your loop at 35 metres.

Better you've done it and know you can handle it than sh1t your pants sometime in the future and freak out.

So instead of talking about it in a lecture, I get the students to experience the same thing, under my supervision, and at least another instructor and or divemaster. They do not breathe the loop, they bailout and then bring the loop down to a breathable PPO2 before bailing back in.

It doesn't matter which agency, I teach this on all my courses, IANTD/TDI or PSA, it is a high O2 drill and it gets taught to all my students, because it is part of the standards and may just save their lives.

Oh and by the way, it is demonstrated by the instructor to all the students at the same depth, before they do it, infact we demonstrate all the skills.

Cheers,

Dave Cooper.

Hi Dave
Tom Mount here, Just a note IANTD forbids practices such as this. I post as you referenced and listed various agencies Having a po2 of 3.0 in the loop exposes a student to risk beyond any justifable need and is a direct viloation of standards that IANTD does enforce. Practices such as this will not be tolerated in IANTD.

Tom at no point is the student breathing the loop with an elevated PPO2 whatsoever, he is on open circuit.

He comes off the loop at a breathable PPO2 and then raises the PPO2 off the loop whilst breathing from an open-circuit regulator.

The instructor checks the PPO2 is lowered before allowing the student back on the loop.

The student is never exposed to the high PPO2.

Hope this clarifies.

Cheers,

Dave.

Just to clarify what was done here, you bailout to Open circuit, inject the O2, then do a diluent flush to bring the level back down to a safe level before going back on the loop. You don't actually breathe a PPO2 of 3.

At least it cleared it up for me. Had read the previous post a bit differently and thought 'WTF'?

Thanks for explaining.
