If we're talking about cave diving, I might as well link this article about Bushman's Hole; https://www.outsideonline.com/adventure-travel/africa/south-africa/Raising-the-Dead.html?page=all In which one of the most experienced divers in the world dies trying to retrieve another diver's body. quote:only six people other than Shaw have ever pulled off successful dives below 820 feet. (More people have walked on the moon, Don Shirley likes to point out.) quote:For example, at depth, oxygen can become toxic, and nitrogen acts like a narcotic—the deeper you go, the stupider you get. Divers compare narcosis to drinking martinis on an empty stomach, and, depending on the gas mix you're using, at 800-plus feet you can feel like you've downed at least four or five of them all at once. Helium is no better; it can send you into nervous, twitching fits. Then, if you don't breathe slowly and deeply, carbon dioxide can build up in your lungs and you'll black out. And if you ascend too quickly, all the nitrogen and helium that has been forced into your tissues under pressure can fizz into tiny bubbles, causing a condition known as the bends, which can result in severe pain, paralysis, and death. quote:At about 800 feet, deeper than he had ever been, Shirley heard the slight, sharp crack of enormous pressure crushing something, and then there was a thud. He looked down: The Hammerhead controller on his left forearm was a wreck. Without it, Shirley would have to constantly monitor the oxygen levels in his rebreather and inject oxygen into his breathing loop manually. It was a full-time occupation, an emergency routine at a life-threatening depth. Shirley was certain that if he went down to Shaw he would join him for eternity. quote:Hand over hand, Shirley descended. As he reached his new depth, nausea hit him and he started to vomit. Shirley would feel the heave coming, pull the regulator from his mouth, throw up, and then replace the regulator. Fighting the vertigo and nausea, he managed to grab some spare gas cylinders from the cluster clipped onto the shot line nearby. The thought that he might die never occurred to him. I will survive, I will survive, he kept telling himself. quote:As soon as he cleared the narrow neck of the chimney, his cave light locked on to Shaw, floating eerily upright, his arms spread wide and the back of his head and shoulders jammed against the ceiling. Shaw's light was hanging below. Looped around it was the cave line he had attached to Deon in October, and cradled almost perfectly in the line, its legs hanging down as if on a swing, was the headless body of Deon Dreyer.

I work in the nuclear industry. I would rather physically handle nuclear waste than work on an oil/gas rig. https://www.youtube.com/watch?v=_PcDNRSsM24 http://www.bbc.com/news/uk-scotland-22840445 LostCosmonaut fucked around with this message at 01:46 on Nov 9, 2016 |
