This is a unique and comprehensive summary of world wide development in this field. It is probably not realised what a vital part closed circuit breathing apparatus played in World War II. Apart from escapes from damaged and sunken submarines by means of the DSEA, and the special attacks on ships by human torpedoes and X-craft, including the mortal damage to the "Tirpitz", an important part of the invasion forces were the landing craft obstruction clearance units. These were special teams of frogmen in oxygen breathing sets who placed demolition charges on the formidable underwater obstructions along the north coast of France.

  • Diving Standards (I.E., Code of Federal Regulations, 29.1910 Subpart T)
    STANDARDS FOR THE CONDUCT OF SCIENTIFIC DIVING June 3, 2004 OFFICE OF POLAR PROGRAMS NATIONAL SCIENCE FOUNDATION 1 FOREWORD The Office of Polar Programs (OPP) of the National Science Foundation (NSF) provides support for underwater diving associated with the research activities it funds in Antarctica. The NSF/OPP’s Standards for the Conduct of Scientific Diving have been developed to ensure that all scientific diving conducted under the aegis of the Office of Polar Programs is conducted in a manner that will maximize protection of scientific divers from accidental injury or illness associated with underwater diving while optimizing the researchers’ ability to conduct research. The OPP Standards have been patterned after the American Academy of Underwater Sciences (AAUS) Standards for Scientific Diving, a document that has provided a template for scientific diving at most academic and research institutions in the United States over the last fifty years. The approach described in the AAUS Standards for Scientific Diving has been recognized by the Occupational Safety and Health Administration (OSHA) as providing an alternate means of protecting divers than their commercial diving standards (i.e., Code of Federal Regulations, 29.1910 Subpart T). There are inherent risks in underwater diving and doing so in polar regions involves additional risks because of the environmental conditions and remoteness. The OPP Standards for the Conduct of Scientific Diving provides a framework within which to manage those risks and allow underwater diving in support of the scientific enterprise in Antarctica to proceed safely. Each scientific diver should acknowledge those risks and commit to conducting their underwater diving activities in accordance with the OPP Standards.

  • Surface-Supplied Diver Training Manual
    Surface-supplied Diver Training Manual Tennessee Aquarium Chattanooga, TN Published by the Diving Control Board Tennessee Aquarium Chattanooga, TN 1st Edition 2007 Purpose Surface-supplied diving is defined in the Tennessee Aquarium Diving Safety Manual (TADSM) as a diving mode in which the diver in the water is supplied from the dive location with compressed gas for breathing and is in voice communication with the tender on the surface. This definition is based upon the requirements outlined in the Occupational Safety and Health Administration’s Code of Federal Regulations. (29 CFR 1910 Subpart T) This federal law outlines the criteria for all commercial diving. The surface-supplied diving mode requires gear and techniques that are not introduced in recreational diver training. This text was designed by the Tennessee Aquarium Diving Control Board to introduce Aquarium divers to the fundamental principles associated with surface-supplied diving. This text should be accompanied by proper practical training, as outlined in Appendix A, to promote safe surface-supplied diving under the auspice of the Tennessee Aquarium. Figure 1 – Secret Reef Dive Show- A primary use of surface-supplied diving at the Tennessee Aquarium. i Introduction There are numerous advantages to surface-supplied diving that make it an excellent choice for many diving operations. First, the diver has the benefit of an unlimited air supply. With a surface-supplied diving system, a diver can theoretically stay underwater forever. Of course, in reality, there are comfort, thermal, and decompression limits. For deep technical diving, a surface-supplied rig relieves the diver of the need to carry numerous stage bottles.

By way of catching up, we have produced a Summer double issue and have the good fortune to be able to publish with a color cover. Coinciding with the Santa Barbara relocation is the appointment, by the Board of Directors, of the first members of the HDS USA Advisory Board. This distinguished group of senior diving professionals, with extensive backgrounds in diving medicine, technical development, commercial, military and sports diving, bring in excess of 300 years of diving experience to the Society. Most of their biographies are the size of town phone directories, and have had to be severely edited for publication. We are honored and gratefulfortheir willing offers of service, and hope that we have done their biographies justice. Details start on page 4. The recently introduced, Founding Benefactor class of membership has proven to be very popular with over half of the thirty available memberships already taken. An opportunity still exists to acquire one of these unique memberships and details of it's benefits are noted on page 9.

  • Best Diving Practice Guidelines*
    Appendix 1. Best Diving Practice Guidelines* A1.1 Divers should terminate the dive while there is still sufficient cylinder pressure to permit them to safely reach the surface and return to shore or boat, including allowing for any decompression time or planned safety stops. A1.2 The dive team should not include a diver who for any reason is not physically or psychologically fit at the time of the dive; or whose dive equipment is not in a safe operating condition in the opinion of the nominated dive leader. A1.3 All dives, including repetitive dives, should preferably be calculated using DCIEM tables (Canadian Defence and Civil Institute for Environmental Medicine), but the use of well-maintained dive computers is acceptable. A1.4 Divers should do a safety stop at 5 m depth for at least 3 minutes immediately before surfacing at the end of each dive where the average depth exceeded 7 metres or the maximum depth exceeded 10 metres. A1.5 If a dive does extend beyond the no-decompression limits, divers should remain awake for at least 1 hour after diving and remain in the company of another person prepared to assist with medical intervention if required. A1.6 Divers should adhere to the buddy system as taught in their dive training. This buddy system is based upon mutual assistance, especially in an emergency. A1.7 If a volunteer diver becomes separated from their buddy: a) the diver shall do a 360-degree search for a maximum of 1 minute looking for bubbles or visual sign of the other diver b) if the lost diver is not located, the searching diver shall return to the surface at the correct ascent rate, still performing the 360-degree search on ascent c) the searching diver will deploy a safety surface marker buoy, use a whistle (or ask where the lost diver is) and wait on surface for 4 minutes d) if the lost diver is still missing, divers are to return to their boat or shore and initiate emergency procedures by contacting emergency services.

  • The Blue Plaque Augustus Siebe Nick Rennison
    The Blue Plaque Augustus Siebe Nick Rennison The 'closed' diving helmet revolutionised diving by allowing the diver to remain underwater for longer and to dive deeper. Many of the great engineering projects of the Victorian era could not have been carried out without the work of divers, and they could not have done their work without the 'closed' helmet. It was invented by a German, Augustus Siebe, who lived and worked in Denmark Street, WC2 for nearly half a century. Siebe was born in Prussia in 1788 and had served as an artillery officer in the Prussian army against Napoleon, being wounded at the Battle of Lepzig in 1813. After the defeat of Napoleon he worked as a watchmaker before moving to London in the year after Waterloo. After living first in High Holborn, Siebe moved to Denmark Street in 1828 and it was there, twelve years later, that he designed his revolutionary ‘closed’ helmet. One of the first opportunities to show how effective Siebe's new helmet was came in the 1840s when divers descended into the waters off Spithead to investigate the wreck of the Royal George, a ship which had sunk there sixty years earlier. The helmet proved so successful that the same basic design was being used by the Royal Navy more than a century later. A man of great ingenuity and inventiveness, Siebe created many other machines at his workshop in Denmark Street, including a weighing machine, a paper-making machine and an ice–making machine. At the Great Exhibition of 1851, he won several medals for his inventions.
