The Sad Story of How Yuri Lipski Was Trapped at the Bottom of the Ocean

mistakes are often seen as opportunities to improve we can look at a mistake and use the experience to learn how to avoid making it again but some mistakes are a one-way street some mistakes create a point of no return where the only thing we can do is watch it unfold in the year 2000 russian diver yuri lipsky made a series of simple mistakes while diving in egypt which would lead to him sinking to the bottom of the ocean and becoming trapped forcing him to live the most terrifying and painful seven minutes of his life as he was slowly poisoned by his own air tank this is his story this is a blue hole it's a large underwater sinkhole which develops in limestone or coral reef the name comes from the fact that from an aerial photograph that's exactly what they look like a deep dark blue hole in the ocean a seemingly bottomless and freezing cold abyss in the otherwise beautiful and sunny ocean they're usually formed during ice ages of the past when water levels were much lower exposing the limestone terrain which erodes a hole in the rock formation then as the planet warms up water levels rise and the hole in rock becomes a deep dark void in the ocean forged in times of ice and swallowed as many things are by a creeping ocean there are many blue holes around the world from the dragon hall in the south china seas to dean's blue hall in the bahamas one such blue hole is the one off the coast of the egyptian peninsula in the red sea known simply as a daha blue hole it's a notorious blue hole for a few reasons it's 328 feet deep and situated very close to the shore making it easily accessible with no vehicle needed it is also enclosed near the surface by a structure called the saddle this structure also prevents any current inside the blue hole and there is only a very weak current at the surface entrance its proximity to shore lack of currents and large array of colorful marine life give the impression that this is a great place for beginner divers to dive this particular blue hole is notorious because it's allegedly the site of the world's largest number of diver fatalities a few days before his death yuri lipski arrived in dahab egypt to visit the popular blue hall before diving he wandered around looking for people to chat to about the dive he was planning he showed up once and he was like everybody else showing up around the hub and we hear it every day i'm here for two days i want to do the canyon and the blue hole regardless experience certification regardless nothing yuri himself was a diving instructor and believed himself to be more than capable of this kind of dive with little to no assistance but he seemed to have little to no interest in certifying himself for the dive via the proper procedure and channels yuri was a technical diver and was reportedly interested in doing a bounce dive which is where the diver descends to the bottom very quickly and then ascends again just as quickly this dangerous practice is usually done to beat a personal depth best by divers not wanting to do it the safe way diving is a popular pastime for millions of people all over the world for philosophers like myself there are a few things more terrifying but generally speaking it's extremely popular there are two types of undersea diving recreational and technical recreational as you might expect is the type of diving most tourists engage in there are two types of recreational diving these are brethold and scuba one using scuba equipment and one using just your own natural ability to hold your breath both types of recreational diving is conducted in areas where the risk of accidental death is low it tends to be done at relatively shallow depths to avoid the need for decompression and mostly open water as opposed to enclosed spaces which may be likely to panic in an experienced diver most times when recreational diving visibility will be very clear and it should be easy to navigate where you're going it's also standard practice for recreational diving to be done with the body hence the term body diving the theme is the same safety first the aim is to enjoy the ocean without invoking a fear of it technical diving is a fairly recent term but which describes pretty much everything else tech divers are sometimes solitary diving in enclosed deeper spaces where visibility and navigation might be a lot harder the theme here could be described as challenge the purpose of technical diving is to challenge yourself see something new or interesting in technical diving you don't just learn about your surroundings you discover things about yourself as the more unforgiving conditions make you realize you were braver than you thought no type of diving is safe but recreational diving is considered to be significantly more safe than technical diving in which the conditions for disaster are far more common the blue hole at the hat is a very popular dive despite the large number of diving deaths which occur there typically divers will start at a point nearby and descend through a narrow cave known as the bells due to the noise that the divers tanks make as they hit the sides of the cave while descending once descended they'll move through an opening which leads into the open ocean the diver will then follow the edge of the shore wall until they reach the lowered part of the blue hole wall called the saddle they will then enter the blue hole over the saddle and move back towards the shore to the exit the depth inside the hole itself maxes out at just over 100 meters or 328 feet the other way to dive the blue hole is to start from the beach itself and dive down into the hole with most people aiming for the arch of 55 meters which is a hole in the cave wall which also leads to the ocean this is how yuri entered the dive diving is extremely dangerous when you don't know what you're doing thanks to movies most of us are aware that ascending too rapidly can cause a variety of problems known as decompression sickness or the bends however most people who aren't technical divers are unaware of the fact that the very air they're breathing from their tanks can cause something called nitrogen narcosis all gases are subject to changes in volume in relation to pressure specifically the pressure of a gas is inversed to its volume and vice versa so as pressure increases the volume of gas decreases this is important to remember in diving for two reasons one as you dive the amount of available air in your tank decreases in volume due to the pressure and becomes more dense meaning the breathing at the same rate will use more air so it will run out much faster two the reduction in gas molecule volume means that gases can move outside the bloodstream and lungs where it should be and dissolve inside lipid tissue of cell membranes the deeper you go the stronger this effect is the effects on your body are dramatic this can cause the sufferer to feel non-noticeable symptoms at 10 meter depth between 10 and 30 meters you'll experience mild euphoria mild impairment of multifunction between 30 and 50 meters you'll get delayed responses to audio and visual stimuli you'll have a false sense of confidence and you'll start to engage in idiopathic laughing and anxiety between 50 and 70 meters you'll start to feel very sleepy you'll have strongly impaired judgment confusion hallucination dizziness and extreme terror from 70 to 90 meters you'll get total loss of concentration loss of dexterity loss of memory but increased excitability anything deeper than 90 meters and you'll start to experience intense hallucinations increased hearing and visual sensitivity or total loss of vision dizziness depressive and manic states unconsciousness and death to counter this problem technical divers venturing deeper where the gas concentration increases will mix helium into their tanks so the tank which previously just contained nitrogen and oxygen will also contain helium to dilute the other two gases and make them less concentrated as pressure increases this is called tri-mix the reason divers don't just use pure oxygen is because pure oxygen causes oxygen toxicity our bodies have evolved to breathe a mixture of gases and when there is too much oxygen there's not enough hemoglobin in our blood to carry that oxygen where it needs to go and it ends up in places where it shouldn't be and this can cause blood vision confusion chest pain breathing difficulty convulsions and death even the thing which keeps you alive will kill you if you breathe too much of it yuri prepared his camera for the day's dive he had opting against diving with a buddy his equipment for the day was the necessary wetsuit gloves flippers mask a buoyancy control device and a wrist monitor he was also wearing a weighted diving belt and carrying an underwater camera on his back was one single tank of air despite thinking himself a very competent diver yuri made a few very crucial mistakes the first was that his air tank did not contain trimex it was a simple nitrogen oxygen mix the second was that he hadn't taken into account the added weight of his camera when calculating how heavy his weight belt needed to be the final mistake was that he had not checked his equipment thoroughly enough and did not know that his buoyancy control device didn't function correctly and would not be able to prevent him from sinking too deep these would prove to be mistakes which would cost jury his life after preparing his camera yuri entered the water and began to descend as he began to drop he realized that his rate of descent was far too fast and so began to use his buoyancy control device to slow his descent but upon turning the valve nothing happened he did not slow down quickly he began to sink to depths which he had not intended to go as he sank deeper the nitrogen in his tank began to decrease in volume and increase in concentration quickly flooding his system with nitrogen in a very short time a strong sense of confusion began to cloud his judgment he turns the valve again to try to inflate the device and send himself back to the surface but again it doesn't work as he reached this point the concentration of oxygen in each breath was causing him to have chest pains when breathing and likely causing him to panic as he ditched his weight belt in a final attempt to achieve some level of buoyancy and float to the surface unfortunately for yuri with no working control device he would not be able to create enough buoyancy to lift himself from the ocean floor the pressure of the ocean above him was far too great and he was slowly and painfully claimed by the ocean you
