Scuba diving – An Introduction
When Human started to travel he found "wheels" and this gave birth to Tourism. But when he reached the Sea, He thought that was the end of world. But Diving paved the way to explore another world under beneath the water. He started learning life under sea and started to learn techniques to stay under water for long time. That was back in 100 B.C, To reduce pressure divers would pour oil into their ears and mouths before diving into sea. Leonardo da Vinci has dreamt about a device which would help man to breathe under water for more than an hour. So the quest of a device urged in minds of several scientists that made to invent Scuba.
Scuba - Self Contained Underwater Breathing Apparatus, is a form of underwater diving in which a diver uses a scuba set to breathe underwater for recreation or commercial purpose. Scuba divers carry their own source of oxygen gas for breathing, Which allows them to surf under water for a long time. Usually all diver wears these equipment on his back and swims underwater with a special dress with fins on the feet which is easy for mobility in the water as same as fish fins.
The History of Scuba Diving
Scuba diving has mainly designed and created for the purpose in world wars. In those days the soldiers used to wear scuba diving equipment and they were called a frogman. Emile Gagnan and Jacques-Yves Cousteau developed the first successful and commercial scuba sets were the Aqualung open-circuit units, in which compressed gas in tank which was used for inhaled and then exhaled into the water, and this system of scuba is still most popular today.
Risks with Scuba Diving
Many risk involves with scuba diving, Because we are going against the nature. The first risk is the changes in air pressure that can rupture our eardrum which is probably the most dangerous risk involved in scuba diving. All our body parts should be equalized by the pressure surrounded you and it varies according to the depth of the water. The next is "oxygen toxicity", Another common problem which is more dangerous and life threatening and usually it cause diver drowning. But this is preventable when we have a good knowledge and basic skills in sea diving. Nitrogen narcosis is an effect on the brain of gaseous nitrogen that occurs to divers who go below 100 FSW(Friction Stir Welding), Due to the laws of partial pressures. There are several other dangers to face when you dive under water and its best you get trained well and know your worst case scenario before you dive.
