The diver handled a very scary situation well and has excellent buddies who helped him in this situation. Learning rebreather myself I can say this is not a good situation to be in (can be life threatening) and his level of calm while troubleshooting is commendable. It is never the wrong decision to bailout.
I guess I'll stay with air. Less bottom time but I know what I'm breathing, and I'm one of the few that doesn't mind doing 20 minutes of decompression.
Shutting the o2 and then Feathering the o2 right thing to do. Good reaction. The only thing I would question is whether there is a buzzer and why the HUD weren’t going mental.
Pagani Zonda the Meg does not have an audible warning (no buzzer, like some rebreathers do). The HUD (Heads Up Display) on the Meg is a red, orange, and green light near the divers eye. It would have been blinking a rapid & continuous green light to warn the diver of a high PPO2 (partial pressure of oxygen). I believe it was blinking, but hard to see in the light from the video.
Progression of technology as now currently 2023 it is common to have an optical display (replacing the LED HUD) with even more defined details directly in the eyeball of the diverse mask. Also vibrational alerts for critical situations is now common place. At 50 years of age, I grew up with cars that did not even know of the existence of a rear back up monitor now it is standard equipment.
I'm glad there are so many people willing to beta test these things so they get better, more reliable, and more accessible to us average divers. Blowing loud bubbles and scaring away the fishes sucks :(
We have a good practice, that when we have a photographer (the one, that knows what he is doing with the DSLR - not everybody with some gopro...) underwater, there is always someone to watch him. The photographers are so immersed into the composition, that they are sometimes forgetting, that they are also immersed in the water... And this does not matter if OC/CC... (I'm on CC, photo. on D12 OC and i'm still the one, who is looking on his gauges, even when i know, that he is looking too.) I'm also photographer (but only landscape, thus out of water) so i know, that when one is really concentrating on the objects in front of camera, the rest of universe is somehow suppressed. I'm often enjoying the dive as a "security diver", but i'm happy with that.
I bring my camera on both OC and CCR dives. Just need to also monitor instruments on CCR dives, especially the rebreather computer, I was taught to check it every 30 seconds.
And this is why I dive a Kiss CCR with an orifice instead of a computer controlled solenoid. The more I dive this thing and look at eCCR failures, the more I don't understand why Kiss rebreathers arnt much more common. The list of things to go wrong is almost halved, and I'm in control....not a computer. Nice work identifying the problem and working around it though.
Stuff like this is why I'd be scared to dive on a rebreather. Yeah, I know there are many advantages. But the more complex the equipment, the more failure points there are. Glad everyone was okay. Dive safe.
the diver had a h.u.d display infront of him...how come he could not see this giving a warning...was the hud disconnected...glad he did not get a 02 hit...
Thank you for commenting! The HUD was not disconnected, probably his vision was overshadowed by the light of the video because that is very strong (2 x 3700 lumens). The flow of the open stuked solenoid is very high, a few seconds of free flow are sufficient to raise PO2 greatly. Marcelo told me that when he realized the PO2 was in 2.0, that is, a few seconds after the end of the sena of the film of shows the computer blinking. I already went through similar situation and finished the dive doing manual flight in the same way.
László Mocsári ..hi my friend...it is a good lesson to see how all of a sudden a perfect dive could end in disaster..thanks for sharing video as its good for other or new ccr folks to see ...safe diving mate...
bob thomas it's been my experience that the biggest cause of issues on rebreather is complacency not saying the guy did not see it, just did not notice. I tell my students "if you walk by a broken window enough times, suddenly it's not broken anymore " like watching your gauges it's something you must notice not just see
The divers astute mind to bail out saved his life! Let’s be honest with our assessment all SCUBA equipment OC or CCR is subject to failure at any given time no different than aircraft or automobiles. it boils down to the ability of the operator being able to quickly identify a fault condition and being able to execute the appropriate response to mitigate a safety of life situation.
Well done 👍 great buddy and good drills. Was it a case of adding o2 yourself to remain within the safe range then until surface. Not a rebreather diver so sorry if it's a bone question.
Joe Spencer you can only add yourself if the O2 cylinder is reachable and you can control the valve yourself on and off No point using then manual button as the solenoid will be adding it whether you like it or not.
Dear Rodolpho, thanks for watching and commenting! It seems to me that Marcelo's first reaction was to inject diluent, however the solenoid stucked open below 30 m is difficult to control the PO2 with this maneuver alone. That's because he went to bailout. We tried to diagnose the problem in the depth by disconnecting the manual oxygen addition hose which did not solve. There were buoyancy problems... Faced with the situation, I signaled for us to abort the dive. At the decompression stops (shallow depth), we were able to hear the free flow of O2 when the cylinder was opened. The Free flow through the open solenoid was intense, I'm not sure if an ascent within a safe speed would be enough to keep the PO2 at acceptable levels.
@@laszlomocsari2118 Now everything make sense! You did the right turning off the O2 cylinder and disconnecting the hose, and he did right changing to the bailout. You guys did it great!
I'm not a rebreather diver, but I read some of their manuals. I know the ADV on some models like the JJ will free-flow when you are vertical and head down. This wouldn't cause a high PPO since it's just injecting diluent. I wonder if the oxygen addition valve can free-flow when you are in a head-down vertical position like when this diver entered the shipwreck? What rebreather is he using?
No. your orientation wouldn't cause a free flow of O2. his solenoid, which is responsible for O2 injection, was stuck in an open position due to dirt in the system.
Did the diver bailout and then leave the wreck? The way the video is edited it suggest events happened the other way around which does not seem sensible.
Thanks for watching and commenting on my video! You apparently did not understand the video! The Marcelo had is similar to having the BC in which the power is in free flow, with regard to buoyancy. Would you find it easy to stay in the trim? The elevation of PO2 was only part of the problem. The continuous injection of oxygen into the circuit dramatically changes buoyancy.
What a stupid comment this is... If you have a CCR then use it. You would get far more bottom time, and feel much better after a dive at 32 m on CCR compared to OC

James Goddard, Thanks for watching and commenting on my video! By the question I see that you are not a diver. Yes it is the oxygen partial pressure. The measure used in this video is absolute atmosphere (ATA), that is, when the diver's computer shows 1.3, is equivalent, on the surface, to breathe 130% O2.
@@laszlomocsari2118 no I am but new to the sport, logged 15 dives. I don't understand what the problem your friend had here . Can you explain what happened
James Goddard, Welcome to the sport! To reduce the decompression time, PN2 should be reduced . (reduction of "inert" gas uptake into tissues). This is achieved by using shallow depths, by increasing PO2 or both. There are limits to breathing O2 (0.16 - 1.6 ATA). Below this we have hypoxia and above hyperoxia. Both can cause loss of consciousness and consequently death of the diver. With rebreathers the usual maximum limit is 1.3 ATA. In this video this limit has been exceeded enough.
They will stick quite easily if you don’t get them serviced I’ve had the same thing. Bailing out on less than 2 is just not necessary. DiL flush and if you can’t reach your o2 bottle if you’re too fat like me, then a normal assent should sort anyway. Only trouble is the O2 bottle emptying if you’ve got deco at 6 m and less. high PPO2 no problem from 6 m anyway
1.4 is the "safe max"(though some navy divers have managed to have incidents at that, and they've gone to 1.3 max), 1.6 is considered the "emergency max"(it's the old safe max). Around 2.0 is where most people will eventually convulse. It's not an exact science. Sort of like narcosis it can vary from person to person and dive to dive how susceptible they are. Exposure time also matters.
Jason Flather Thanks for watching and commenting on my video! Thank you also for alerting me to the bad practice! I thought there was more than one safe way on which the diver could choose and that getting out of the loop to BO was always the best option. If you watch the video closely in a second moment Marcelo tried to return to the loop but the diluent injection could not keep PO2 low.
Thanks for watching and commenting on my video! At this point (PO2 = 2.5) the diver was out of the loop. The video shows this. This PO2 is not immediately lethal. Just as a reminder, hyperbaric oxygen therapy that uses PO2 of 2.4 ATA 90 min with intervals of airbreaks and therapeutic recompression to treat DCI uses 2.8 ATA. It is true that underwater conditions are different and the threads are much less tolerated.

Nobody is perfect we learn from our MISTAKES.

The litgh of video distracted me. I took about 40 seconds
Hopefully we learn from others mistakes too.
Unfortunately rebreathers have a very low tolerance for mistakes. Too often it's one and done.

That could have been really bad had the buddy or himself not noticed
Thx for sharing!
the heavy metal song makes this video even more scary
that way they say look at the ccr computer 3-4 times a min.
Better do not do it at all, the rebreather dive. The electronics in it, salt water, batery, etc. Thank you for this moovie. Very dangerous!
Great recovery.
Amazing how the solenoid got dirt particles in the area described
Id like to know how?
Isn’t this normally a sealed unit ?
It can come in from the oxygen connection from the outside
And then we have a discussion about O2 clean and flammability concerns 🙄

Hello Laslo! Is the canister in this video standard Megalodon made from aluminum?
Sergei Shaman Reznikov Hello! Yes. All ISC canisters are aluminum
The computer does not vibrate?
Unfortunately this computer does not vibrate
Why return to the circuit for deco if you know it's bad?
He fixed it by feathering his O2 valve. Once the problem is identified he could go back on the loop. Its no problem.
Plus in shallow water as the ambient pressure drops the ppo2 will drop too
Did the diver bailout and then leave the wreck? The way the video is edited it suggest events happened the other way around which does not seem sensible.
It really does! When I edited I thought that Marcelo had gone first to bailout but in reality he made the flush of diluent.
Hopefully good lessons learnt.
Safe diving
Any chance you could show Exactly how to service the solenoid? Please
Sorry for late reply! This head was sent by Marcelo to the replace of Shearwater Predator and did a complete overhaul that was not done.
@@laszlomocsari2118 thats the best answer ever. I dont think its wise to just rebuild the selenoid. there should be more to it than that.
When I opening the solenoid there were solid particles. I did just the cleaning, removing the particles with a dry cloth.
All metal components should be ultrasonically cleaned if free of plastic and o-rings.
I dont understand any of this, but judging by the music is seemed critical. . what is PO2? Poisen Oxygen?
partial pressure
The divers trim and need to hold onto things says something about him not being ready for the task load of a rebreather or penetration diving.

Why did he not do a DIL flush?
He did. He dil flushed while he left the wreck and then bailed until he could fix the problem. Then returned to the unit.
mccr is a better solution for me !
What is po2
it is the partial pressure of oxygen in the breathing loop. 1.1 to 1.3 is kinda a normal range to run in.
It's unbelievable the amount of expensive junk you divers carry now for a day out...
........... safe diving to all............
@bristol That's only for a really deep diving. For a normal dive one oxygen 8-12 L cylinder, dive computer and regulator is enough.
@@AdrianoCROST I see you are not a diver.
Sorry guys. I'm just OW guy. May I know what's going on?
Uncontrollable oxygen addition to the breathing loop due to the stuck valve. The partial pressure of oxygen had risen to dangerous levels.

do you bring a nuclear bomb to a paintball fight?
What a stupid comment this is... If you have a CCR then use it. You would get far more bottom time, and feel much better after a dive at 32 m on CCR compared to OC

High PPO cause cause oxygen toxicity, which can cause you to go into convulsions and spit out your regulator.
That's crazy! Isn't 1.4 supposed to be the max?
1.4 is the "safe max"(though some navy divers have managed to have incidents at that, and they've gone to 1.3 max), 1.6 is considered the "emergency max"(it's the old safe max).

Exposure time also matters.
What is the PO2 supposed to be?
Wind waker Depends on the the setting for that particular dive. 1.3 is a good place to start.
1.1 to 1.3 is kinda a normal range to run in.
Sorry but that’s bad diving practice. Once you’d seen high ppo2 you should have immediately done a diluent flush. There is no need to bail out.
