Download or read book Repetitive Diving Decompression Tables written by and published by . This book was released on 1957 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decompression procedure for repetitive diving to depths of 190 feet was devised employing modified Haldane principles which have been reported previously. The repetitive diving tables provide a system by which a diver can determine the necessary increase in decompression time on the second and successive dives, based on the amount of excess inert gas tension in his body after completion of the previous dive. The amount by which the decompression time must be increased varies inversely with the time (on surface) interval between dives. The information for using this system is obtained from four tables i.e. Decompression Table, No Decompression Table, Surface Interval Table and the Repetitive Dive Table. The validity of this procedure was tested by performing 62 repetitive dives with random combinations of depth, time and surface interval.

Available in PDF, EPUB and Kindle. Book excerpt: SCUBA is a fun, relaxing, educational, interesting, and -- if approached properly -- safe activity, it is nonetheless a sport that has risks. SCUBA diving is in fact an extreme sport that can injure or even kill very quickly, and in some very nasty ways. What we are doing is entering an alien environment that is normally hostile to human life. We cannot breathe in water without some kind of mechanical assistance. These are facts and the details should be covered in every Open Water (OW) class. All too often in today's society, however, people do not want to take the time to properly prepare and get the education to safely take on new tasks. Some agencies appear to have responded to this by developing training programs that turn out high numbers of certified divers in shorter time frames, necessitating the reduction of time spent on what I consider to be some necessary basic skills. While this has resulted in great numbers of new divers entering the water, it has not resulted in many of those divers staying in the water. New divers are often given just enough training to enable them to dive in the most benign conditions under close supervision. Even then, there are still those who find out their initial training was just not adequate. It is at this point that they either make the decision to get more training or they leave the sport. The latter happens all too often. The former, when it does happen, does not always occur for the right reasons. Students should return to training to expand their diving and learn new skills; they should not have to return for new training just to be able to enjoy the sport safely. To require students to come back for basic information is something I find very troubling, and in some cases, has actually cost divers their lives. A lack of rescue instruction has resulted in a number of diver deaths when buddies did not know how to drop weights, support a diver at the surface, or even stay in contact with their buddy. This is another area frequently talked about, but all too often not actually put into practice. The concept of always diving with a buddy and just what that means in the "real world" is often given too little attention. Unfortunately, it is impossible to foresee every conceivable situation that can arise, but there are many basic issues that can be covered. The following chapters will hopefully address much of what is being overlooked or delayed in many programs as they exist today. It is my hope that this information also finds its way into the hands of those who have not yet begun the training process. I have included a chapter on how to select an instructor based on the quality of instruction and the content of the course. In some cases, these classes may cost more than the less comprehensive courses also available, but usually they do not. In fact, when you consider the additional skills and education gained from a more comprehensive course, you will find that you have received much more value for each dollar spent. In addition, you gain priceless benefits in the form of greater confidence, enjoyment, skills, and -- most importantly -- safety. Enjoy and dive safe

This book was released on with total page 1066 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 1,000 total pages .... INTRODUCTION 1-1.1 Purpose. This chapter provides a general history of the development of military diving operations. 1-1.2 Scope. This chapter outlines the hard work and dedication of a number of individuals who were pioneers in the development of diving technology. As with any endeavor, it is important to build on the discoveries of our predecessors and not repeat mistakes of the past. 1-1.3 Role of the U.S. Navy. The U.S. Navy is a leader in the development of modern diving and underwater operations. The general requirements of national defense and the specific requirements of underwater reconnaissance, demolition, ordnance disposal, construction, ship maintenance, search, rescue and salvage operations repeatedly give impetus to training and development. Navy diving is no longer limited to tactical combat operations, wartime salvage, and submarine sinkings. Fleet diving has become increasingly important and diversified since World War II. A major part of the diving mission is inspecting and repairing naval vessels to minimize downtime and the need for dry-docking. Other aspects of fleet diving include recovering practice and research torpedoes, installing and repairing underwater electronic arrays, underwater construction, and locating and recovering downed aircraft.
