Fatal Diving Accident Caught on Tape

by skoant • 9,161,009 views

Video taped by Yuri Lipski who died in a diving accident in the "Blue Hole", Dahab, Egypt at 28.4.2000. The video shows rare footage taken by Yuri's camera, analyzed by specialists. Since 1968,...

.............I have no idea what's going on.

+MrWalkwaySc2 I did but it's not necessarily needed for 40m nitrox would just increase your no decompression limits any deeper than 40m it notnally gets into tec diving which use a tri mix which is air helium and nitrogen so the oxygen toxicity no longer happens

So much for an instructor, he doesn't even know to use the correct air mix for those depths. But it's sad that he's dead. In fact, it's been 15 years since he died, weirdly.

The Blue Hole is 130m deep- more than deep enough to cause nitrogen narcosis, especially without trimix, and he was not diving with trimix. Nitrogen narcosis can happen past 30m of water. Nitrogen narcosis causes mental impairment, usually with an inappropriate sense of calm, even laughter, but sometimes conversely terror. The person is usually unable to understand they've been impaired. They will be unable to understand their surroundings and react appropriately. The onset can be rapid. Not to be confused with decompression sickness, aka "the bends". The actual mechanism of nitrogen narcosis- what actually happens to cause impairment- is not actually known, but there are some recent theories. The Blue Hole in the video has 40 acknowledged diving deaths, others say the total may be twice as high.

If those were true translations, these so called specialists are morons. I have seen many dive professionals do stupid things like breaking safety rules and taking shortcuts in procedures because they thought they were experienced enough and things they taught beginners don't apply to them anymore. I have done thousands of dives and many of them technical dives (cave, deep, mixed gas and more),  I have taught hundreds of courses (from divemaster and specialty to bubblemaker),  I have always studied anything to do with diving in free time when I could so I am not another person that doesn't have a clue about diving when I say this. This diver never called for help.  Those little squeaks you hear every so often is him trying to equalize.  He descended a bit quick and equalized late often therefor because of a larger pressure build up, it gets harder to equalize, requires more of an effort (not necessarily a dangerous thing as long as you don't allow TOO much pressure build up) and then he will make those sounds.  I have experienced this with myself many times and have it on personal video so it can be heard on video. He left the group and descended with the intent to get to where he was or even a bit further when he looked at his computer. Gas narcosis is not damaging to the body, it only impairs the mind which can result in lack of ability to perform tasks with your limbs as well, you will become unconscious from narcosis at some point under enough pressure (just like laughing gas puts you to sleep, it's the exact same thing, that gas is narcotic at sea level) but that does not seem to be the case here. Oxygen at a pressure of 1.6ATA is safe for decompression, after that you risk toxicity (also not harmful to the body in scuba diving) more and more the higher the pressure gets.  Since they all seemed to be diving air (about 21% oxygen) it would no longer be safe after 66 meters depth.  The worst thing that can happen is convulsions and that will result in losing your regulator from your mouth and drowning.  This seems to be the case shortly after looking at his computer, having a fit on the ground, the sound of a regulator free flowing for a few seconds after falling out of the mouth and then lying on the ground motionless (indeed there seems to be just over a minute missing from his video but might be irrelevant anyways). As for the two loud buzzing sounds, that may have been his regulator being hard to breath in when looking upwards but they definitely were no cries for help.  Yelling into a regulator underwater does not sound like that at all. Diving is safe, it is worth it, just don't be an idiot that thinks he is invincible and can break safety rules no matter your experience.

I couldn't agree more on what you said, I commented the exact same thing , you are obviously experienced because I thought the exact same stuff, I just thought he stopped the freeflow himself cause a bit is missing so he wouldn't have survived for a full min without air except if he used the alt which we don't see. Obviously the experts are idiots or we don't see the full story, only the military stuff said something right really which is the descent rate. Take care and dive safe

Viral, if you listen to the whole un-narrated video without watching, it really makes even more sense what happened. Around 7 minutes on the actual video time, you hear a few distinct pops. Then four or five BCD inflate attempts, a manual inflate, and afterwards he plummets like a rock. He was in panic the whole way down. On the bottom he tries one last BCD inflate after he tries to ditch weight, but it just runs open line. At that point you are watching unicorns and Easter Bunnies dig your grave, being 92 meters under on straight air. That alone is about the equivalent of 10 shots of liquor directly into your bloodstream all at once just from nitro narc.

+Nardor I respectfully don't agree with the people and the instructors on here about nitrogen narcosis in Yuri's case. Of course all said is true in regards to trimix and EAN gases and of course on most divers narcosis can and will occur after a certain depth- give or take 42 meters- but the lad here still had the cool to camera his watch at 81 m long after nitrogen(and subsequently N2O5)should have been so high in his blood that he wouldn't be able to tell his hands from his toes... He descented extremely fast, his buddy was probably still at 30 meters when he was at 90 and he was over weighted??? All that from an experienced diver??? And narcosed he had the sense to actually deliberately show his Dive computer on camera??? He was trying to prove something, but I don't know what really and there is definitely another side to the story. As well, when he hits the sand I heard a freeflow from his reg which he had the sane to stop by turning the reg down, who does that under narcosis man?? Anyways got carried away, but I am a tech diver myself and I can't believe an experienced diver did that, looks like suicide to me really man. Just my 2 psi Take care and dive safe

Rule of thumb with SCUBA and air tanks: the further down you go, the more narc'd you get. With his distance, especially without a buddy, he entered the "You're Screwed Zone."

If you have a oxygen tank on like he did, the nitrogen becomes poison when u go to deep because of the position and dead animals, when it gets in your tank you only have a matter of time before you can get back up before you die, but it is hard because it is killing you slowly

No. Impaired judgement from nitrogen narcosis which lead to him losing his mouthpiece and drowning. It's a terrible way to go but pretty common in that spot. The Blue Hole is beautiful but dangerous.

From what little research I've gathered about this particular video, these analysts are not diving experts, rather they are psychologists, medical professionals and ex-naval personnel. They wanted to have a wide range of opinions on what happens to Yuri so they assembled a group of people from different backgrounds.

The guy in this video wasn't doing it properly. He went way below the maximum recreational diving limit of 40M and he did not have a buddy. When you are trained, have a trained buddy and dive in a safe area above 40M it is a perfectly safe sport.

this Russian " Lipski  "guy entered his dive with only one tank of air & was down at least 300ft (maybe a little more at points)He would of been better off using  trimix, a combination of oxygen, nitrogen, and helium that reduces narcosis. the blue hole is well known in diving circles & has the nickname "divers cemetery"  Please .remember its not just your life you put at risk but also your buddy & anyone with the unfortunate task of retrieving your corpse.  btw the blue hole is a lot deeper than 130ft as some are saying here ,for example the Blue Hole on the northeast side of the sink hole & 184 feet below the surface there is a horizontal tunnel 85ft long that leads to the open sea.May he RIP.

@ 93 metres you need to be on an O2 mix of 6% due to the fact that O2 is deadly to us as we decend.  This is why we also use Nitrogen and Helium to mix with it.  At the surface we are breathing about a mix of (for everyone that breaths air on land) 73% Nitrogen and 27% O2. I don't know if he had the proper gas mixtures...perhaps one or more tanks were contaminated, empty (low) or he was experiencing Nitrogen Narcosis (starts to effect most people at about 30-40 metres, although I've heard of people getting "Narced" at 20 metres).   As a fellow diver, I had to wipe the tears from my eyes knowing what he was heading to.  I haven't seen many posts that have an idea as to what they found, if they were able to recover the body AND the gear.  I would be interested to know if anyone knows if they ever found out what, or at least have a good "guesstumate" as to what happened.   I'm not an expert (I am a Dive Master/Rescue diver and am certified to dive solo.) so I'm just throwing out my thoughts right after viewing this and welcome all ideas backed with why you might have the idea/ideas. No matter the reason, may he rest in peace, and may his family and friends find themselves able to remember the fun times, the loving times, the times they all had and not remember this video as what they think of when they think of thier friend/loved one.  Very hard not to do, but it is well worth the effort.  I've had to deal with watching friends die in front of me (I'm a bush pilot) and find that it is much better to remember the person's life, not death.  Again, it's hard to do, but it becomes easier, and more welcome to your mental health, the more you're able to do it. Sorry for the mini-novel.

Narcosis doesn't happen because you descend too fast, it happens because you descend too far. He went down so deep for bragging rights I believe.
Report spam or abuse
This is so sad but that is way too deep to be on straight air with a single tank and on your own. The deepest that have been to was about 150 feet for one minute. I was surprised how heavy I got and how much air I needed to add to my BC just to maintain neutral buoyancy and prevent a runaway descent. The narcosis was getting unpleasant as well. 300 feet on air, on your own and with a single tank is lunacy. Unfortunately he found that out the hard way. Other divers please watch and learn.

I concur...I did a dive in Dominica back in October, we went down to 120 feet and I started feeling odd after about two minutes...I immediately signaled the dive master and ascended to about 80 feet, held on to a large rock to get my bearings and normalcy back, then signaled all was ok and continued the dive....always pay attention to how you are feeling, don't "shake off" anything..it's not worth it.

It amazes me how many people commenting about this accident here have no clue about scuba diving, recreational and technical. This video shows a young man attempting a dive he wasn't ready for. He didn't have the knowledge, the skill or the equipment to safely dive so deep. Young men sometimes can attempt foolish things to prove themselves. He took a camera along, so i assume the intention was to show this dive off to others. And he payed with his life for the risk he took willingly but ignorant of the dangers. We should all just be sad for him and his family and friends, learn from his mistakes and treat the ocen with the respect it deserves. THat would be worth more than all those uninformed speculations.

+boy rage Yoou are not a qualified diver. In Egypt maybe where you take a 2 hour long class to get a card saying you are a diver and you can really just jump to the water and peddle up and down. I went in diving classes for 3 years to get the first degree certificate so I could dive to 20meters without anyone with me. I was then no able to take a higher level certificate because I was to small (15) and I had to wait but then I stopped diving.

Either poorly trained, a lazy student or he committed suicide. Direct from the training books: - Around 32m on air and nitrogen narcosis kicks in which is like getting drunk. - On air, 56.6m or max of 66.6m and oxygen poisoning kicks in, paralyzing the jaws (unable to keep regulator in the mouth) and limbs, including convulsion.

His descent was too fast. Probably narcosis. Many factors and effects different on different people. Today you're fine but tomorrow you may not be able to do the same.Over 80m oxygen becomes toxic. I'm no technical diver, but you want to dive deeper than that you use trimix. When doing an openwater dive it is very easy to lose track of descent rate and when you start to panic, it gets worse. Golden rule is never move further away than arms length from your buddy. Deep diving takes time to get your body used to the pressure. To say that he was an instructor means nothing. I have dived with many instructors having the minimum required dives. That is not experience. I have dived with old boys with an openwater 1 qualification, but with 4000 dives behind them. There are old divers and bold divers, but there are no old bold divers.

Didn't go back and read all the comments, but the guy is supposedly thrashing around at 17:09:56 and then it jumps to 17:11:02 to a still--what happened from 17:09:57 to to 17:11:01 (a minute and 4 seconds). Why was that cut out? What you would expect to see is him losing consciousness and then gradually sinking (or floating up) but the current should still be moving him so you should still see sand around him floating and still hear whatever that sound was (regulator)?. It jumps to a still frame. Also the sound seems very clear for being underwater. Anyone cover that in previous posts? a few seconds ago · Edited · Like

My observation, he did say help, was disorientated, and in the confusion went down even more and was surprised when he found himself even deeper into the ocean, panicking and taking off his mouth-piece. Then you of course say, "well it's a piece of cake going back up because you know where the light is". You don't know how this person felt at that point, maybe they were allready zoned out at that point.
Report spam or abuse
Being over-weighted is a common problem for new divers, but if he was using a different wet suit or lost weight, he may have different weight requirements potentially making him over weighted. As he descended he might have over inflated the BC and if it was old it could have burst(sound for help), therefore providing him zero positive buoyancy.  Also as you go deeper the amount buoyancy provide by any air trapped in the BC and the buoyancy provided by the weight suit decreases as well make the decent increase.   Normally you would use a weight system with a quick release, but if he stuffed the weights in his BC he may not have been able to dump the weights.  Once he got below 150 ft the nitrogen narcosis could have kicked in and make him less effective, especially if he was taking medication or have been drinking.  If i were in this position for some crazy reason would remove the BC and then separate the tank, but if he was doing this he might have lost the regulator trying to achieve this.

Did something drag him down? From early on when they say he was safe, he was asking for help. Like he knew he lost of control for some reason. At which point he descends fast, but you'd think, he might still scream for help but if no one is around why waste your breath? Maybe he had too much weight, couldn't untie the weights, needed help to untie, no help came, stuck weights dragged him down, he struggles to still get it off, pressure gets to him, poor man dies.

Nitrogen (and partly oxygen) narcosis made him 'not sane' sadly. In order to inhale at depth the air we breathe has to be the same pressure as the water. Every 10m/33ft is another atmosphere (atm) on top of the weight of the air above, so at 90m he would have been breathing air at 10 atm or 147 psi As CO2 triggers breathing - NOT a lack of oxygen - we breath just as often as on the surface so waste vast amounts of air. This is the problem that rebreathers solve by removing CO2, replacing oxygen, and recyling that same air. At 90m, Yuri consumed 10 times as much air per breath as he would have on the surface, and his lungs saw 10 times as many molecules of oxygen and nitrogen. This excess gets dissolved in the blood like CO2 in a softdrink.  We burn oxygen and there's less to start with so nitrogen is the main problem. Like coke, it forms bubbles when the pressure drops fast (ie. you open the bottle suddenly) which can be fatal, or lead to paralysis etc. Slow ascent and decompression/safety stops at specific depths to off-gas through your breath is the equivalent of opening your coke bottle very very slowly. The more gas in your coke (longer time at depth, greater depth) the slower you have to open it, it can take many hours to ascend from depth. Oxygen and nitrogen breathed at such high (partial) pressures both cause narcosis, or "rapture of the deep", a drunk feeling that makes you even sillier to the point of offering your regulator to a fish. Worse, oxygen gets toxic when breathed at much more than an equivalent of about 1.6 times the density of 100% surface oxygen. With 21% oxygen in his bottle at 10 bar Yuri was breathing at 2.1, well over the (perhaps conservative) 1.6 limit.  Some people are fine, some aren't, diving's a bit of a lottery in that respect but he was much deeper than the depths where oxygen toxicity usually kicks in and the result can be severe spasms and spitting your regulators out and drowning. Bottom line you shouldn't drive air - or worse, enriched air (more oxygen than normal) - beyond roughly HALF the depth that Yuri achieved.  Trimix - a mixture of oxygen, helium and nitrogen - lets you create the perfect blend for your chosen depth. At 90m, trimix 16/52 (16% oxygen, 52% helium, 32% nitrogen) might have done the trick without having to carry another bottle for shallow depths, although a second bottle is a no brainer at 90m anyway, but I've never dived deep so it's all just theory to me. What I do know for sure is that there's good reason why diving below 40m is called technical diving, it's not something you just have a go at. Given his rate of descent and single tank he probably wanted to bottom-bounce (touch it and head up immediately) before he absorbed enough nitrogen to need long decompression stops which he didn't have enough air for. Fast descent or not you'll still get narcosis and probably oxygen toxicity, and die sadly :(

+Geoff Infield  Hey there, great explanation! I dive my self, but never any deeper at 25 meters, and I dive in nordic oceans = Dry suit. nonetheless, my question is as follows : Any sane person would keep their BCD somewhat tightly strapped on, but at his speed of descent he could not have very much air in his BCD, nor at 90 Meters since we never hear the overfilling plugs pop ? im thinking with that much weight, at that depth, and so little air in the west. Wouldn't it actually squeeze the poor man rather super tight ?

Seems like he got dragged down by something..Don't see how anyone can be that dumb especially if he's an instructor.Not to mention if he did say help that compels me to believe it even more so.Because as he was saying help it was almost as if he was trying to swim back to the reef as if something grabbed onto his leg..Pretty odd..

He most likely got hit with narcosis. He may have even thought he was going up. not down. The fact that he was calling out is a sign he was not himself. Very sad but a lesson to all who dive on air below 40m. .

Listen guys to anyone who knows about this sport properly,he died from misadventure and diving passed his certification. At that depth the mind does crazy things with nitrogen narcosis. Even with a clear mind with the pressure at that depth a standard BCD would probably not inflate. Any buddy would have stopped also at the right depth otherwise we be watching two die. Scuba is one the greatest sports on earth but you must only dive to your technical ability and certification Don't just think depth kills research cave diving deaths from divers not following rules. Rest in peace to the Dahab diver and learn from this tragedy

He obviously wasn't experienced.  If you get disoriented when diving you're supposed to blow bubbles and follow where they go, inflate your BDU and let yourself float up.  Where was his buddy?  No hand signals?  A lot of errors that are in place to prevent this type of thing.  How was he even diving 200+ feet when he didn't know the basics? At my grandparents house, they live in Florida keys and grandpa and my brothers watched a guy off the docks diving, they watched him drown and die, because he was inexperienced.  I really wish more people would get certified before taking up diving, it's fun but...you will die if you don't know what you're doing

Blue hole's not horizontal, it's a big hole...

It starts out vertical, and there is a horizontal cave near the bottom or something like that. He also had rocks in his suit.

They said diving isn't worth it but it's ok if are not so stupid as this guy that takes too much and is too heavy so he sinks and gets entengled (why didn't he inflate his bcd).

The only thing I can think of is that he somehow got confused in which direction he was swimming in and thought he was swimming upwards after finding out about the oxygen tank? Never been diving myself but I'm pretty sure it's unlikely though.

the bubbles always tell which way is up

+Sighborg Guy Nitrogen Narcosis. At that depth the nitrogen in his air mix would have made him act as if he were drunk. It affects your judgement, your motor reflexes, and your memory. That's why deep divers divers use exotic air mixes. Usually helium and oxygen.

I am fairly confident he didn't say anything at all, least of all "Help".  First of all, was English his native language? Also, the sound was very mechanical, not a normal voice, even via a regulator.  He was very well aware that no one could hear him, unless he would have been saying something for the recording.  He was not yet breathing heavily and wasn't yet in trouble at that point anyway.  When he got to the bottom, he was showing off to the camera how deep he went. (I didn't see any cramping either.  That is just how your hand works when you flex your arm to see your computer on your wrist.) Besides that, the squeaking sound did not sound human but more like the regulator making a noise upon inspiration, which mine used to do at times.  You can even hear a bit of a squeak later in the video after it was at depth.  Besides, if you listen, the sound was upon inhalation, not upon exhalation. Finally, it looked to me that he tried to get to the bottom, take a video of it to show off to his buddies when he got back up...and then something went wrong.  He was not down there very long and would not be able to stay for more than just a couple of minutes at that depth anyway without getting bent and he clearly had no plans to do decompression dives.  So, he didn't plan to stay down long.  Based upon how rapid his descent was, he clearly intended to get down fast, record proof of how deep it was, look around for a minute and get back up.  I would be surprised if the problem was that he ran out of air, as he never started his ascent.  I wonder if they did an autopsy to see if he had a medical emergency right before he fell face first into the dirt and was not able to ascend. Oh, I dove for years and am a speech-language pathologist...which is why I am pretty certain he wasn't asking for help.

He dived so deep that the water above him was too heavy and it started to push him down.

Lipski died at just over 300 feet underwater. At this depth, the body is subject to nitrogen narcosis, which can play havoc on the mind by inducing overconfidence, euphoria, hallucinations, confusion, and impaired judgment. It didn't help that Lipski had just one tank full of air — technical divers are better served by multiple tanks filled with trimix, a combination of oxygen, nitrogen, and helium that reduces narcosis.

Regardless the case. He's dead! It was a terrible event that occurred and no one will ever know exactly what happened, except that it did and its tragic.
Report spam or abuse
I've watched this at least 10 times now and I still can't figure out exactly what happened. Did he mean to go that deep? Or did he start descending uncontrollably?

Yuri killed himself. Most of you have never completed ( or attempted ) an open water dive or a solo dive. So you have no way to understand. Yuri's descent was controlled......Any novice diver that is in distress does  2 things.....1) Breathes heavily  2)  Panics. There is no experienced diver in the world ( not even an amateur) that does an Uncontrolled Descent... ( We call it uncontrolled because, the depth is beyond our control; there is no bottom we can safely achieve ) ......with his head facing down, breathing in control,takes time to look at his depth gauge and does nothing to change his decent rate. Its impossible.

+quivalla that's debatable. 2nd stage reg could be replaced with an independent backup, SpairAir. Sounds like he had neither.

+quivalla Even if we assume that the buddy system is overrated that doesn't mean that you shouldn't use it. While it is a good idea to be able to handle things on your own and not to be overly reliant on your buddy there are some situations you just can't handle on your own. The point is that for all the dives where a buddy turned out to be unnecessary there will always be dives where having a buddy means the difference between life and death. As the tragedy shown in this video demonstrates its better to be safe than sorry.

People need to make this distinction...this is a video, not a view into what he was actually SEEING.......unfortunately, who knows what he was really "seeing". Just because WE can see the gauge clearly, doesn't mean he was able to or even knew what he was doing anymore.
