The lesson of life: divers are full of anger and suffering from drowning

Release date:2017-06-15 14:31:50

Ann and Bill are ready for scuba diving. Everything here is better than they think. They dive in the local quarry, and the condition is good on the whole. When they reached the platform 60 feet deep, Ann noticed a problem with Bill's ligand tape and came up to him and tried to help him. She had no idea what the problem would be. Bill, with his weight belt and equipment, suddenly twisted aside and knocked Ann's regulator out of her mouth. Things went from bad to worse. Diver
Ann, a 24 year old novice diver, is in good health. She has 15 diving records, including four dives seven months prior to the initial dive certification. She tried to dive into the local quarry every month with his potential companion, Bill, in his diving lessons. They soon became good friends, and Ann was happy to have an experienced partner with similar interests. They are excited about scuba diving opportunities and extra training. Divers are used to rent and personal equipment. They only buy affordable equipment.
That dive?
The conditions of the morning were almost the same as those of them diving. The water temperature is cool and the typical diving season is drawing to a close. Ann and Bill can also wear ordinary wet clothes.
They plan to do a typical quarry dive. They will swim to the surface buoy and then descend to a 60 foot platform. From there, they plan to enter the shallow water area in their own way and explore some of the sunken spots in the quarry. They have tried several similar basic dives before then.
When Ann and Bill came to the platform, Ann noticed that Bill was more comfortable with his counterweight. He immediately knelt on the platform, trying to get things under control. After watching Bill struggling for a while, Ann approached him and tried to help him. The colder she sat on the platform, the more she wanted to dive.
Bill's BC loosened and he tried to grab his counterweight buckle. Ann approaches the side of Bill's twist and raises his BC. The sudden movement knocked Ann's regulator out of her mouth. Realizing what had happened, Bill immediately tried to help Ann put her regulator back in her mouth. In the process of helping her, his weight belt was loose and fell behind the platform behind him. Bill immediately began to float to the surface, and his weight belt had fallen into a distant place before he realized it. He began to return to the bottom, but in this process, Bill lost a flipper and his cylinder from the BC loose. He rose all the way to the surface of the water and could not go down again. When he realized that Ann was not behind him, he sent a signal for help to the shore. The two divers nearby responded quickly, but they did not find Ann for 15 minutes. When they finally found her, she had lost consciousness, and her regulator was still in her mouth.
On the water, rescuers began to work hard to recover, but they did not succeed. Ann's autopsy report showed that she died of drowning.
accident analysis
On the face of it, one might think that the diving accident was caused by diving equipment. In fact, the accident is due to the failure to use the equipment properly and correctly deal with unexpected problems. In the "leisure diving safety" in the book Dan Orr and I refer to the Canadian province of Ontario, chief physician of George high voltage equipment Molly togba Dr. Harpur. "We do not have a documented example of the direct cause of the diver's death due to equipment failures, as a result of a diver's reaction to a problem," he said."
Every diver has problems with equipment, it's just a matter of time. As the saying goes, "if you don't have a problem like this, it means you don't dive too much."." The key to problem management is to respond quickly and calmly, and then move on. Losing control is the key to a simple problem escalating into a big one. Bill is depressed because of his weights, and may be a little nervous. He was so absorbed in his problems that he didn't see Ann coming towards him. When she tried to help, he hurried to open the regulator movement of her from her mouth. At this point, the two divers had problems, but no problem was insurmountable. Ann could have come back, retrieved her regulator, and hinted that Bill would stop and allow her to help him. But they did not do so.
This article reflects a recurring theme: the human panic reaction. When panic came, narrow narrow vision perception. It limits your reaction so that you can't think calmly through the question. Both Ann and Bill panicked. Ann was unable to retrieve her regulator (the skills that every diver had learned) and then failed to make an emergency ascent to the surface. Instead, she simply drowned at the bottom of the water and was drowned in the back. Bill when he lost his weight belt and confound, increasingly erratic to return to the bottom, causing him to lose a flipper and cylinder loose.
Many divers never practice emergency skills during their initial training. They do not review, adjust, retrieve or remove and re wear their weight bands. These two basic skills can save diving, allowing two divers to continue shortly after the interruption. It's easy to be a joke later - just a minor interlude.
It could be that Ann and Bil are using unfamiliar equipment because some of their equipment is rented. In this case
