IN THE PREVIOUS ARTICLE, we settled on the recommendation that equipment used to control any breathing gas mix containing 25 percent oxygen and above at typical scuba cylinder pressures should be designed and considered suitable for oxygen use. Possible debates aside, we’ll examine what oxygen cleaning means. How often should gear be oxygen cleaned, and […]
DAN INTRODUCED THE FIRST standardized emergency oxygen course for divers as lay providers in 1991. More people trained in oxygen delivery means that providers in dive locations worldwide need to have emergency oxygen units available. Obtaining oxygen refills, however, is an ongoing problem …
Divers Alert Network (DAN) mengelola jaringan ruang rekompresi global, yang terdiri atas basis data semua ruang hiperbarik yang memiliki kemampuan dan kemauan untuk merawat penyelam yang cedera.
Ketidaksesuaian antara katup dan silinder baru-baru ini mengakibatkan hasil yang mematikan di Eropa. Masalah ini dapat dicegah dengan pelatihan formal, pelatihan khusus fungsi dan pemahaman dasar tentang katup tangki scuba dan ulir silinder.
TIGA GAS yang umumnya digunakan dalam penyelaman rekreasi dan teknis adalah oksigen, nitrogen, dan helium. Nitrogen adalah yang paling melimpah dan biasanya merupakan gas standar, tetapi tampaknya tidak ada yang peduli dengan kemurniannya, meskipun Asosiasi Gas Terkompresi (CGA) A.S. menyediakan tingkat kemurnian, atau tingkatan, untuk berbagai aplikasi.
AFTER THE INITAL SCARE AND LOCKDOWNS FROM COVID-19, divers soon started to explore ways to safely get back into the water. Disinfection has always been a consideration in diving, but we needed new standards to allay fears of uncontrolled transmission of infectious diseases.
On Sept. 2, 2019, the small passenger vessel Conception burned to the waterline off Santa Cruz Island, California, killing 34 people. This wasn’t the first liveaboard fire, but the fearful reactions to this deadly tragedy echoed throughout the scuba industry. Liveaboard fires that have occurred since this incident have further fueled industry concerns.
Most divers know their scuba cylinders need a visual inspection every year and a hydrostatic test every five years (referred to as a requalification or a hydro). The actual regulations for cylinders and other dive equipment, however, are less clear.
The U.S. Food and Drug Administration (FDA) classifies oxygen as a drug when provided to an injured or ill person. It requires specific labeling and product controls and must be individually prescribed to someone suffering from an ailment. When used incorrectly, oxygen can cause damage to someone’s health.
DAN’s vision is to make every dive incident- and accident-free. Improvements in training, equipment, operations, dive boats, and dive computers have made diving significantly safer. The safety of a dive, however, relies heavily on the diver’s practices.
