This video is of a man named Yuri Lipski. This isn’t exactly a video showing his death but it is leading up to his death. They showed this to us when I was going through dive school. It is a great example of nitrogen narcosis and its effects on the body. Yuri as you can see, at the beginning of the video seems just fine. The diver was diving right next to a shelf and due to having too much equipment attached to his and not managing buoyancy well, as a result he sank fast. This is textbook negligence. It happened so fast that he was already feeling the effects of nitrogen narcosis before he could recover. He was most likely out of his mind halfway through this video. The first major risk to this is diving without a bottom-out and second he was weighed down with too much weight and equipment. At the end of this video when the diver reached bottom you see him glance at his computer or adjust his mask and it registered 91.4 meters. 91 meters is 298 feet and way past the depth limit for air diving. It is incredibly disturbing seeing the change in lighting throughout this video the diver descends deeper and deeper the screen gets darker and darker. It is so easy for even the most experienced divers to lose track of depth and time. Diving is a matter of being consistent and planning each dive. Know the risks, know your bottom limit, and time at that depth.
Be safe out there!
