Answer to FAQ’s on Technical Diving – Regulator of Death

Answer to FAQ’s on Technical Diving – Regulator of Death

Hi everyone is Steve Martin here from I’m going to answer a tec training frequently asked
question, well it’s actually a few questions I answering these as part of my online sidemount training videos, this is a segment on technical training. Now what people ask
is what to do, if your Deco regulator freeflows? How do you breathe from it? Can you switch regulator 1st stages underwater? Can you breathe from a low pressure
regulator hose itself? and can you breathe directly from a cylinder without
a regulator? Now what I do was part of my technical training is actually have a
regulator which is simulated to free flow all the time and I conduct certain
skills with that. Now it’s not a question of can you breathe from a LP Reg hose and can you breathe from a cylinder valve. It really should be a question of
should you!? and for me I would say unsafe to do that and it’s definitely NOT
needed!! So you can see I’m turning on the valve
here and the regulators free flowing and now flutter on… off to make it more interesting, I’ll remove
the mouthpiece and this happens because like you see here you can get tears in
the mouthpiece and it might be much simply to remove it a good idea is to keep a backup in your
pouch, cable tie and a mouthpiece you can see there air was on then off, again air on, air off. So I’m feathering the valve or flutter breathing it. One of the problems are if there wasn’t a cable tie on it and the regulator mouthpiece did stay in
your mouth most divers can actually have a problem
with this, and you know you still think you’re breathing from the regulator
because it actually feels like that so a good tip there is to always check
your equipment prior to go in and take a good look at the mouthpiece for wear and
tear but also the cable tie itself is secured and the mouthpiece won’t come
off like he has done here So now I am removing the 2nd stage and this is just to show you a test of… you know why you shouldn’t breathe directly from a low
pressure regulator hose. I’m not gonna do that here. I’m just gonna show you how
much pressure actually comes through it and you can see is quite surprising
amount and you know being able to vary that amount yourself with the handwheel
on the cylinder, the cylinder valve wheel it’s just NOT practical and why would a diver ever need to do this, if you regulator didn’t work you can use another one the regulators job basically is to regulate the pressure you breathe, right? so without the regulator, no diver could breathe effectively and safely to exit a dive or to actually make Deco stops so one of the things you could do is
remove the first stage, which you see a diver doing here switch with a working one off your other
cylinder and then screw back on. Your going need to purge it now, because they’ll be water
in it of course, so give it a good purge and now you can see the air comes out and the
diver then would be able to breathe effectively from it. Now of course if you
going to do this you must get that regulator serviced and the 1st stage
by a service technician after the dive my preference would always be to switch
out the 1st stage, if I thought fluttering the valve would cause me more
stress, or was difficult on a decompression stop that I was trying to
make. Trying to breathe directly from a cylinder valve without a regulator, I would just
forget this!! I mean you know there’s no divers that really are ever going need to do that, should they be planning their gas management reserves properly one of the best things you can do, to ensure you don’t need to do this is to, 1 carry a spare mouthpiece and cable tie
in your side mount pouch and also get your 1st stage and 2nd stage serviced regularly. So I hope you’ve enjoyed this video, you can find more videos like this and
actually watch promotional videos about my complete online training series and
they’re found on my website, that’s A massive thank you as well to all the people who have invested in my online training videos so far If you want to drop any comments on the video, and let me know you thought of it that would be appreciated

  1. I always thought you could breathe from a low pressure hose or tank as a last resort, but this video proves it's not worth it. Thanks for making a video about it so we do not have to.

  2. In my PADI instruction I learned to breathe from a freeflowing regulator. Just left one side of the mouthpiece out of your mouth and let the excess air escape. And pay close attention to your air, cause it will depleat the cilinder in a breaze. Another thing, I notice at 2:30 that you inhale, let a bit of air escape and hold your breathe. In spite you let some air escape, shouldn't you keep a little flow of bubbles escaping from your lungs? I know you have a superb buoyancy control, but…

  3. Man I do agree with you, I have had the same questions and some of the situations in real 2009 and I answered exactly the same more or less but off course others who wanna rain you down says a non answered question which is " what if " thanks mate for the video I do appreciate it.

  4. As an annomily in my training I've taught myself to sip off a cylinder while feathering the valve for upwards of 20 minutes at a time. As expertly stated in the video it isn't a likely scenario nor a plan A contingency. However, it can and has been done and I'm grateful I have it in my tool box when Murphy goes diving with me.

  5. Hey Steve. Enjoy your videos – very well produced and presented. In this case, you can breath from an lp regulator hose by crimping the hose, then sipping. It works best with rubber hoses, but I've done it with flex hoses as well. I would only do this if absolutely necessary, as with the deco bottle. Divers should also carry enough air to cover decompression if the deco bottle fails. Switching out first stages would really be a last resort, but worth noting. Also, a diver who does not maintain his/her personal regulators should not be diving, especially deco regs. And yes, a basic understanding of reg. repair should be taught to all divers (clearing sand, etc.)

  6. Great info in this video. It actually answered some questions that I've been pondering for some time. Cheers, Q

  7. Very good, I did my tdi adv tri mix with Aaron Bruce, being a toolmaker I made him lots of gadgets which I would say he still has today…Keep up you videos Tim

  8. Shouldn't divers drill on these techniques before they go real world? Not judging I really haven't any practical expertise to draw from so was just curious. Training for worst case until everything is locked into the divers muscle memory would seem like it should a prerequisite. Maybe the miliatry just made me overly obsessed with precision and preparation i don't know. Anyways love the video's I'm getting to learn allot 🙂 🙂

  9. Billy deans in key west …who was the first instructor to teach trim I'd back in 1991 had his Paul ryles swoping regulator at a deco stop constantly for 3 months and apart from once when the o ring had dropped out they never had a problem ….all the regulators were scubapro mk2 s or sherwood Bruts …unbalanced 1st stages !!……this was over 25 years ago !!

  10. Very helpful skills and answers to questions that some of us have had for years – like breathing through the hose or directly from a tank! Thank you.

  11. Thanks Steve. As always great info, may save someones life by knowing something that you may not think of at the time.

  12. Well that was very informative! I remember watching 47 meters down with a bunch of friends on a scuba placement and remember seeing the bits where the people trapped underwater end up swapping the first stages onto different tanks… Didn't think it would be possible (especially since it's a hefty beer fine to leave the dust cap off when washing the regs) but what you describe makes sense to me.

    (It occurs to me that the film makes literally no sense in many ways, they wear full-face regulators to allow for dialogue and exposition underwater but I don't think this would work with that kind of kit)

    Don't mean to say that's all I learned, it's very cool to see some of the skills used in tec diving and certainly food for thought… I dived with a guy using sidemount once and I'll admit it's got it's uses and advantages… Certainly worth consideration if I was to go for getting my own BCD in the next few years…

  13. isn't the answer realy to keep your kit in good order and change 'o' etc regularly. Also don't just rely on the electronics, work out your stops etc. befor and keep info on a slate

  14. Master diver, E.R.Cross, had done thev’technifscts column in ‘ Skin Diver ‘ magazine,which no longer publishes , as PaulTzimolis is gone.

  15. Rebreathers are regulator s of death.Breathing directly from a tank or l.p.hose is stupid.Buddy breathing mis safer.
