The PSDA board of directors provided expertise involving public safety diving in sharing best practices and technical knowledge. A special thanks to Chuck Elgin, North Carolina Underwater Response Team, for his dedication and hard work assisting in the development of this publication. This guide is intended to be consistent with all existing OSHA standards; therefore, if an area is considered by the reader to be inconsistent with a standard, then the OSHA standard should be followed. -
No Limits Freediving
1 No Limits Freediving "The challenges to the respiratory function of the breath-hold diver' are formidable. One has to marvel at the ability of the human body to cope with stresses that far exceed what normal terrestrial life requires." Claes Lundgren, Director, Center for Research and Education in Special Environments A woman in a deeply relaxed state floats in the water next to a diving buoy. She is clad in a figure-hugging wetsuit, a dive computer strapped to her right wrist, and another to her calf. She wears strange form-hugging silicone goggles that distort her eyes, giving her a strange bug-eyed appearance. A couple of meters away, five support divers tread water near a diving platform, watching her perform an elaborate breathing ritual while she hangs onto a metal tube fitted with two crossbars. A few meters below the buoy, we see that the metal tube is in fact a weighted sled attached to a cable descending into the dark-blue water. Her eyes are still closed as she begins performing a series of final inhalations, breathing faster and faster. Photographers on the media boats snap pictures as she performs her final few deep and long hyperventilations, eliminating carbon dioxide from her body. Then, a thumbs-up to her surface crew, a pinch of the nose clip, one final lungful of air, and the woman closes her eyes, wraps her knees around the bottom bar of the sled, releases a brake device, and disappears gracefully beneath the waves. The harsh sounds of the wind and waves suddenly cease and are replaced by the effervescent bubbling of air being released from the regulators of scuba-divers. -
Stefano Ruia
LA NARCOSI DA AZOTO di Stefano Ruia 1 - L’EBBREZZA DEGLI ABISSI La narcosi da azoto, definita dai medici “sindrome neuropsichica da aria compressa” (legata cioè alla respirazione di aria in pressione), è uno dei fenomeni che i subacquei imparano a conoscere subito, poiché influenza le immersioni a profondità già comprese nella fascia detta “ricreativa”, e con la quale tutti abbiamo dovuto imparare a convivere. Eppure ancora oggi la scienza non ha compreso del tutto i meccanismi biologici di questo stato di alterazione psicologica e ottenebramento mentale. Approfondiamo con questo dossier lo “stato dell’arte” su questo fenomeno, tanto comune e misterioso. Fu uno dei primi film subacquei che vidi. Era il “Il Mondo del Silenzio” di Cousteau, filmato – come operatore - da quel grande cineasta che sarà Louis Malle. Fu girato nella seconda metà degli anni ’50 dello scorso secolo. Beh, non sono così vecchio, ma quando la TV lo ripropose, qualche anno dopo, mi fu permesso di vederlo (allora per guardare la TV dopo “Carosello” i bambini dovevano ottenere – e non era facile - il permesso … bei tempi!). Una scena mi colpì molto. Durante una delle consuete “razzie” sui fondali (a quei tempi erano permesse e anzi rappresentavano la spinta più forte all’immersione con le bombole) il subacqueo perdeva il controllo e lo riacquistava solo in risalita. Aveva subito l’influsso della perfida “ebbrezza di profondità”. Questo terribile nemico mi metteva in agitazione, soprattutto quando mio padre partiva per andare a caccia subacquea al mare. Allora non facevo differenza fra apnea e autorespiratore. Così, come molti altri subacquei, sono cresciuto con l’idea che gli eroi della “Calipso” (la nave di Cousteau) per primi avessero scoperto questo tremendo fenomeno con cui fare i conti. -
Bill's Cave Diving Lexicon
Bill’s Cave Diving Lexicon 120 Rule: Noticing from the Navy NDL table that, for certain depths, depth + bottom time = 120 so that the NDL can be determined by subtracting the depth from 120. 200 DIN: Thread depth in a DIN valve and associated pressure (200 BAR) that can be handled. This size (7 threads) allows for a DIN to yoke conversion. 300 DIN: Thread depth in a DIN valve that provides the most secure (9 threads) connection and can withstand 300 BAR pressure. 5 nines pure: 99.999% pure, as in a gas. 50-50: Gas mix of 50% oxygen and 50% nitrogen used for decompression gas. 6351-T6 Aluminum Alloy: Alloy that has had problems with tank ruptures. Absolute Pressure: Total pressure being exerted on a diver At sea level Absolute pressure is 1 ATA and it increases by 1 ATA for each 33fsw (34ffw). ADDD (Air, Duration, Depth, Distance): Limits for dive termination acronym minimum Air volume/pressure, maximum Duration of dive, maximum Depth of dive, and maximum Distance of penetration. ADV (Automatic Deflation Valve, and Automatic Diluent Valve ): Device on a buoyancy compensator that allows for rapid air purging, and device on a rebreather that dilutes the breathing mix. AGE (Arterial Gas Embolism): A lung expansion injury. A condition in which gas bubbles enter the arterial system and cause damage by blocking blood flow to vital organs, most commonly the brain. This is generally caused by air passing through the walls of the alveoli into the bloodstream. Air: A gas mixture of Oxygen (21%), Nitrogen (78%), and other gasses (1%, Helium, Argon, etc.). -
Safe Transportation Systems for Sustainable Commercial Human Spaceflight / Small Launchers: Concepts and Operations (Part II) (9-D6.2)
69th International Astronautical Congress 2018 Paper ID: 47238 IAF SPACE TRANSPORTATION SOLUTIONS AND INNOVATIONS SYMPOSIUM (D2) Safe Transportation Systems for Sustainable Commercial Human Spaceflight / Small Launchers: Concepts and Operations (Part II) (9-D6.2) Author: Mr. Charles Lauer Blue Abyss, United States, [email protected] Mr. Simon Evetts Blue Abyss, United Kingdom, [email protected] Mr. John Vickers Blue Abyss, United Kingdom, [email protected] A NEW COMMERCIAL SPACEFLIGHT TRAINING PROGRAM FOR SUBORBITAL AND ORBITAL SPACEFLIGHT Abstract After many years of engineering and development, suborbital and orbital commercial spaceflight vehi- cles are finally expected to enter service in the next year or two. Blue Origin is already flying FAA/AST licensed unmanned commercial suborbital research flights from their private spaceport in west Texas and expect to begin testing their New Shepard vehicle with onboard crews this year. Virgin Galactic should begin powered flight tests on the second SpaceShipTwo in 2018 with commercial suborbital tourism flights potentially beginning in 2019. For orbital commercial spaceflight, SpaceX and Boeing should both be- gin flight testing and enter initial commercial flight service to the ISS before the close of 2019. These suborbital and orbital vehicle programs now provide a solid business foundation for the development of dedicated commercial spaceflight training programs to enable safe and enjoyable spaceflight experiences for commercial customers. Blue Abyss Ltd. is developing a dedicated spaceflight training facility and associated training curricula in Central Bedfordshire about an hour north of central London. The facility will be located at the former RAF Henlow base as part of a regional development plan for the Oxford { Cambridge Technology Corridor. -

Adm Issue 10 Finnished
4x4x4x4 Four times a year Four times the copy Four times the quality Four times the dive experience Advanced Diver Magazine might just be a quarterly magazine, printing four issues a year. Still, compared to all other U.S. monthly dive maga- zines, Advanced Diver provides four times the copy, four times the quality and four times the dive experience. The staff and contribu- tors at ADM are all about diving, diving more than should be legally allowed. We are constantly out in the field "doing it," exploring, photographing and gathering the latest information about what we love to do. In this issue, you might notice that ADM is once again expanding by 16 pages to bring you, our readers, even more information and contin- ued high-quality photography. Our goal is to be the best dive magazine in the history of diving! I think we are on the right track. Tell us what you think and read about what others have to say in the new "letters to bubba" section found on page 17.
