DEPTH DIVING [9 records]

Record 1 2023-05-09

English

Subject field(s)
  • Underwater Diving (Sports)
CONT

As stated above, recreational dive planners are for "no-decompression" diving. That's unfortunately a rather ambiguous term because, of course, we do decompress as we ascend to the surface again. What it really means is that the data in the tables shows the length of time you can stay at a certain depth and still be able to ascend without making mandatory scheduled "decompression stops. "

In addition to depth markings at the edge of the pool, a lifeline or a 4 inch wide marking strip of contrasting colour on the pool floor and walls must be placed at the 5 foot depth to designate the boundary between the swimming and diving areas of the pool.

Les parois d'une piscine doivent être équipées d'accessoires en retrait permettant d'attacher, dans la zone moins profonde, à une distance minimale de 300 mm de la ligne de dénivellation entre la pente douce et la pente raide, une ligne de sécurité supportée par des bouées pour avertir les baigneurs de cette dénivellation.

DEF

... a person-shaped, articulated submersible that allows the "diver" to function at one atmosphere of pressure at any depth.

CONT

Atmospheric diving suits... They can be used for very deep dives, 600 metres/2000 feet, for many hours without the normal hazards of depth, such as the decompression sickness or nitrogen narcosis. They look like suits of armour, with elaborate pressure joints to allow articulation while resisting the large difference between the inside and outside pressure. They are often constructed from aluminium, weigh around 250 kg/500 pounds and have propellors allowing them to move in water. Often they are lowered from a support vessel, which supplies breathing gas, electric power and communications to the suit through an umbilical cable. The suit may incorporate a rebreather-type breathing system in the event of an emergency where the umbilical supply fails.

CONT

An American from Chicago named Lodner D. Phillips designed the first completely enclosed atmospheric diving suit in 1856. His design consisted of a barrel-shaped upper torso with domed ends and was the first to incorporate ball and socket type joints in the articulated arms and legs. No record exists to indicate the Phillips suit was ever built, but many features of the design can be seen in similar more successful suits over a half century later.

CONT

In 1882 the brothers Carmagalle took out a patent for an armour-plated diving suit. The most satisfactory modern version of this apparatus is the rigid jointed Neufeldt-Kuhnke type, which is lowered and raised by means of a cable and allows the diver to observe and make limited movements.

CONT

Following Lethbridge and Rowe's exploits there was little to no mention of the armoured diving suit until 1838, an almost 80 year lull from Lethbridge's death in 1759.... W. H. Taylor designed the first known armoured diving suit with articulating joints in 1838. The suit was to be surface-supplied and had accordion-like joints of spring steel, reinforced and water sealed with leather. From his drawing, it seems that either Taylor had no intentions of his suit being a true atmospheric diving suit, or else had no understanding of the depth-pressure relationship. The suit appeared to exhaust directly into the surrounding water from a short hose located at the divers waist. Therefore, the interior pressure would have had to be greater than the water pressure at depth. Also, the soft cloth joints of the suit would have most likely collapsed when exposed to any considerable pressure.

CONT

Where diving operations are carried out during the course of a drilling program, the operator shall ensure that the divers do not, except in the case of an emergency involving the safety of personnel, carry out operations at, descend to or ascend from a work site located at a depth of 50 m or more unless the descent and ascent are carried out in and the operations are carried out from a submarine, an armoured diving suit, a diving bell or other diving vehicle.

CONT

Lorsque des travaux de plongée sont effectués dans le cadre d'un programme de forage, l'exploitant doit, sauf dans un cas d'urgence mettant en cause la sécurité du personnel, veiller à ce que les plongeurs utilisent un sous-marin, un scaphandre renforcé, une cloche de plongée ou un autre véhicule de plongée pour descendre à un lieu de travail situé à une profondeur de 50 m ou plus, pour y effectuer des travaux ou pour en remonter.
