Yes. Without a licence and training, filling a tank by yourself is dangerous.

Dissolved nitrogen and nitrogen narcosis

There is the extension phase where you reach out as far as possible. Then the catch phase is next its where you initially catch the water then it leads right into the actual pull phase where the water is thrust behind you. which leads directly into the recovery phase of the stroke where the arm moves back to catch more water and start the cycle again.

Diving accident victims are placed in a hyperbaric chamber primarily to treat decompression sickness, also known as "the bends." This condition occurs when nitrogen bubbles form in the body due to rapid ascent after deep diving. The hyperbaric chamber increases atmospheric pressure, allowing the nitrogen bubbles to dissolve back into the bloodstream and reducing the risk of tissue damage. Additionally, the chamber can enhance oxygen delivery to tissues, aiding in recovery from injuries related to diving.

you can poop your pants and eat it.

Key Largo, in the Florida Keys, is known as the Dive Capital of the World.

some wetsuits are white, quicksilver make one ,so do rip curl

Yes, it just has to be empty. I think shipping companies like you to remove the valve first. At that point, it's just another heavy piece of metal.

as soon as your doctor says its okay to (remember to ask him because if you still are recovering in any way it can add danger to scuba diving)

Jacques Yves Cousteau and Emile Gagnan worked together in 1942 and created the first SCUBA unit.

The dive computer essentially calculates in real time the nitrogen levels in your blood used on depth and time (and possible air mixture: ie: NITROX 32%) - they can (and do) much more than that including, timing your dive, ascent rates - some even calculate time left based on how much gas is left in your tank!!!

Technically speaking this has no relevance to the quality or action of diving. It is not a formal signal of any status nor skill level.

In the social context of the dive community it is taken as a sign that the Diver in question is less experienced as this action is one of the most common ways to loose a mask.

(www.scubaboard.com has many references to this practice)

No, it does not. When I was certified, I learned you can pee in your wetsuit, but it sounds kinda gross. This means that you can pee in your wetsuit without it causing any damage. I own a 3mm wetsuit and peeing in it hasn't caused any damage.

Absolutely - air compresses at depth, and because wetsuits are made up of air cells, they compress and lose buoyancy along with the air in the BCD, so divers have to add air while descending. Also, as you breathe air, the tank gets about 6 pounds lighter during the dive, so you need to release air. Finally, as air expands while ascending, you need to let air out.

well, as a pearl diver..i know how long it takes to be under water...before you actually get a pearl, so drowning is number 1..getting eaten by sharks,,number 2..why?.oysters can be found near reefs..means food..means sharks. that's all i can say

There are one-atmosphere suits that do this (the JIM suit was one), but they aren't in the realm of sport diving, either in training or price. If you can't possibly equalize your ears, you're not going to be able to dive. [[User:Cjonb|Cjonb]] 22:37, 2 Jun 2008 (UTC)

The rigid diving suit is pressurized to offset depth pressure and it needs rigidity to prevent it from expanding, allowing the person to swim easily.

actually we dont mix nitrogen nor oxygen we use normal fresh air.

The normal Air is 21% oxygen + 78% Nitrogen + 1% others.

As humans more oxygen can be toxic for us especially underwater.

However, in some cases "Like with Nitrox" we add more oxygen to make the percentage up to 40%, but this require specific training and certification.

Mares sells a wide range of scuba diving equipment that one would need when going on a scuba diving trip. Some equipment include jackets, fins, masks, snorkels as well as spear guns.

anything past 10 metres after that depth your body absorbs nitrogen and that is what gives you the bends if you surface too quickly the nitrogen forms bubbles in you blood and can cause all sorts of problems and even death.

coming from the regulator the hose needs to be placed under the right arm in a position that is reasonably easy to reach by the right hand.

lots of alachol

There are a number of ways of dying as a result of scuba diving but the truth is it has very few deaths considering there is such a high potential for all manner of accidents and how many people take part in the sport each year. If you compared it to something like recreational motorcycle riding, it is very safe indeed. Divers tend to get training, which is a very good thing because they usually learn what is safe and what isn't.

As a result of such low mortality, the statistics are not very significant due to the low numbers. This year 'death by shark attack' has made the list in Australia even though it is extremely rare for a diver to have been killed in such a way. There are probably far fewer deaths as a result of drowning than you might expect too. It is more likely that people will dive too deep and become narcotised, become lost in no-clear surface dives or suffer catastrophic DCS. If the body is not recovered, or even if it has, it can be hard to establish the reason for death. Having said that more injuries are due to boats... getting in and out, being hit by them on the surface etc than serious decompression accidents. I am sure someone has done research on deaths in diving but the main point is that it is a pretty safe sport for trained participants. With good training and safe practices we are all trying to keep it to the realms of 'highly unlikely'
