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.). -

Supervised Dive
EFFECTIVE 1 March 2009 MINIMUM COURSE CONTENT FOR Supervised Diver Certifi cation As Approved By ©2009, Recreational Scuba Training Council, Inc. (RSTC) Recreational Scuba Training Council, Inc. RSTC Coordinator P.O. Box 11083 Jacksonville, FL 32239 USA Recreational Scuba Training Council (RSTC) Minimum Course Content for Supervised Diver Certifi cation 1. Scope and Purpose This standard provides minimum course content requirements for instruction leading to super- vised diver certifi cation in recreational diving with scuba (self-contained underwater breathing appa- ratus). The intent of the standard is to prepare a non diver to the point that he can enjoy scuba diving in open water under controlled conditions—that is, under the supervision of a diving professional (instructor or certifi ed assistant – see defi nitions) and to a limited depth. These requirements do not defi ne full, autonomous certifi cation and should not be confused with Open Water Scuba Certifi cation. (See Recreational Scuba Training Council Minimum Course Content for Open Water Scuba Certifi ca- tion.) The Supervised Diver Certifi cation Standards are a subset of the Open Water Scuba Certifi cation standards. Moreover, as part of the supervised diver course content, supervised divers are informed of the limitations of the certifi cation and urged to continue their training to obtain open water diver certifi - cation. Within the scope of supervised diver training, the requirements of this standard are meant to be com- prehensive, but general in nature. That is, the standard presents all the subject areas essential for su- pervised diver certifi cation, but it does not give a detailed listing of the skills and information encom- passed by each area. -

Swimming Pool 1 Swimming Pool
Swimming pool 1 Swimming pool A swimming pool, swimming bath, wading pool, paddling pool, or simply a pool, is a container filled with water intended for swimming or water-based recreation. There are many standard sizes, the largest of which is the Olympic-size swimming pool. A pool can be built either above or in the ground, and from materials such as concrete (also known as gunite), metal, plastic or fiberglass. Pools that may be used by many people or by the general public are called public, while pools used exclusively by a few people or in a home are called private. Many Backyard swimming pool health clubs, fitness centers and private clubs have public pools used mostly for exercise. Many hotels have pools available for their guests. Hot tubs and spas are pools with hot water, used for relaxation or therapy, and are common in homes, hotels, clubs and massage parlors. Swimming pools are also used for diving and other water sports, as well as for the training of lifeguards and astronauts. History The "Great Bath" at the site of Mohenjo-Daro in modern-day Pakistan was most likely the first swimming pool, dug during the 3rd millennium BC. This pool is A private swimming pool in Tagaytay, Philippines 12 by 7 meters, is lined with bricks and was covered with a tar-based sealant.[1] Ancient Greeks and Romans built artificial pools for athletic training in the palaestras, for nautical games and for military exercises. Roman emperors had private swimming pools in which fish were also kept, hence one of the Latin words for a pool, piscina. -
The Complete Diving System 2 Divator Product Overview
PRODUCT OVERVIEW DIVATOR THE COMPLETE DIVING SYSTEM 2 DIVATOR PRODUCT OVERVIEW A tragic bus accident in Sweden after the Second World War raised the concern that divers could not be quickly deployed to the crash site. The Swedish government asked Interspiro (“AGA” at that time) if they could provide a rapid deployment diving device for search and rescue operations. Interspiro began an extensive research program and in 1948 the Worlds first underwater breathing apparatus for search and rescue was presented to the Swedish authorities. The device, commonly referred to as the “iron bed” (because of the shape of the carrying frame), featured a breathing valve with inhalation and exhalation in the same diaphragm. The first of many Interspiro innovations in the field of diving. Today, over 60 years later, the latest generation of Interspiro SCUBA – DIVATOR – is still the preferred choice for professional divers around the World. The Interspiro diving philosophy is a system approach. The reason is simple and obvious, to obtain the highest possible safety level for professional divers. © 2015 Interspiro AB, Sweden.
