Il contient aussi des traces d'hydrogène 0,000072%, mais aussi d'ozone et de radon. Patrick Baptiste MF1 n° 22108 Formation théorique Nitrox confirmé Composition de l’air Nous considérons que la composition de l’air est la suivante : - Oxygène (O²) 21 % - Azote (N²) 79 % Convention d’appellation Par convention, on désigne ce mélange en citant en premier sa teneur en O² puis sa teneur en N², on obtient une indication du type : O²/N² ou XX / YY . un mélange définit comme suit : 40/60 Désigne un NITROX contenant 40 % d’O² et 60 % de N² Patrick Baptiste MF1 n° 22108 Formation théorique Nitrox confirmé Limites et contraintes Liés à l’augmentation de la pression partielle d’oxygène (PpO²) - Limitation de la profondeur maximum par rapport à l’air( PpO²max = 1,6b .) - Limitation variable de la profondeur en fonction du mélange respiré - Risque d’accident hyperoxique si les profondeurs planchées ou la durée d’utilisation sont dépassés, - Manipulation plus contraignante et plus dangereuse, - Nécessite un matériel spécifique ( compresseur, équipement spécifique si Nitrox > 40/60) - Planification des plongées obligatoires et plus complexes - Prix de revient plus élevé que l’air. -

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. -

Dr Craig Challen SC OAM
Dr Craig Challen SC OAM Australian of the Year 2019, Thai Cave Rescue Diver, Aviator and Keynote Speaker Dr Craig Challen was named Australian of the Year 2019 in recognition of his work to rescue 12 young soccer players and their coach from a flooded Thai cave in Chiang Rai, Thailand in July 2018. Craig is in high demand as a keynote speaker. He presents alone or in partnership with fellow cave rescue diver Dr Richard Harris. An internationally recognised diver, a former vet, CEO and keen aviator, Craig is able to tailor his presentations to suit the audience and is available for question and answer sessions. More about Dr Craig Challen: Craig was about to go on a caving holiday in the Nullarbor Plains, when he was called to help the rescue mission based on his technical expertise. Although he initially thought the rescue would be too difficult to accomplish, he played a leading role in the successful mission. Working 10 to 12 hours a day in extremely dangerous conditions, he repeatedly risked his life as the children were swum, one by one, through the dark and narrow flooded caves. Craig was awarded the Star of Courage for his unwavering and selfless bravery. In 2019 he was recognised as Australian of the Year for Western Australia. One of Australia’s leading technical divers, Craig is a member of the Wet Mules, a diving group that takes on some of the world’s deepest caves. After commencing cave diving in the 1990s he was an early adopter of closed-circuit mixed gas rebreathers. -

It has been only 9 months since the Society was launched in October 1992, and membership has risen rapidly during this period. So rapidly, in fact, that it soon became obvious to the Steering Committee and myself that we would outgrow our position as the North American Chapter of the British Society and would have to restructure our organization. Firmly focusing on the Society's founding objectives of preservation and education, we have recently filed State and Federal papers to structure the Historical Diving Society as a non-profit educational corporation.

Thai Cave Rescue Hero to Speak at Brisbane Conference
XXXXXX DR CRAIG CHALLEN, a retired Perth veterinary surgeon and Australian technical diver and cave explorer, is THAI regarded as one of the best in the world. It was that reputation that led British diver Rick Stanton to call on CAVE Craig’s expertise to rescue the Thai football team from the Tham Luang RESCUE Cave, with his dive buddy and friend, anaesthetist Dr Richard (Harry) Harris. With around 20 years’ diving HERO TO experience, and a depth record (221 metres) to his credit, Craig and Harry were about to embark on another SPEAK AT cave diving adventure on the Nullarbor when the call came to help in the extraordinary rescue mission. BRISBANE The world held its collective breath while the life and death operation went into coordination mode as the CONFERENCE international team examined the best chance of rescue. Then came the rescue mode, and for a few days, Australian diver Dr Craig Challen, people everywhere hoped for a miracle that the boys would be saved. one of the heroes at the heart Not in living memory has there of the recent Thai cave rescue, been such a positive news experience as that which revealed the success will speak at next year’s Rotary of the mission, and the extraordinary Conference in Brisbane, Qld. courage and determination, guided by skill, that the team demonstrated throughout. Only when all the boys had been rescued did Craig and Harry leave the cave. Craig was a reluctant hero, but his attempts to avoid the media throng were overcome when the mission was successfully concluded, and all Australians shared an immense sense of pride in one of our own. -
