In simple words, scuba diving is a form of underwater diving where a diver uses scuba set so that he could breathe underwater and explore the world below water in lakes and oceans for appropriate time. To perform this underwater task, scuba diver has to wear the equipment that enables him to stay below the water surface for a long time.
Most of the scuba divers perform this task just for recreation and to explore the beautiful world that exists in the ocean waters. They also traverse the depths of waters for scientific, commercial and military purposes other than just recreational. Early scuba diving was relied on breath hold or on air pumped from the surface (basically compressed air). However, surface supplied and scuba diving both facilitates the divers to stay in water for longer as compared to breath holding techniques which are used in free diving and snorkelling.
Apart from the oxygen set, the diver also has to wear swimfins on their feet for comfort swimming.
Hazards and Dangers
As per the 1970 North American study, Scuba diving has been found 96 times more dangerous as compared to driving a vehicle. There are several things that a diver has to focus on before going to perform this task. Well, no doubt he is well trained after which he gets certification go for recreational or professional works. While diving under water, one can get injuries due to the changes in air pressure. Decompression sickness is one of the effects of breathing high pressure gas. Breathing high pressure gas in depth brings many different risks to the diver. Nitrogen narcosis is one of the risk factor which acts as mechanism alike the nitrous oxide or laughing gas that is administered as anesthesia. It can impair the diver’s judgment and fall him into dangerous situations. Maintaining oxygen toxicity and wearing dry suit for reducing exposure (contact with body heat) are some of the important factors that one have to consider before performing underwater diving. Moreover, the diver has to avoid skin cuts and grazes which are prevented by wearing diving suits and using numerous techniques to increase the ability of the diver to dive deeper and longer under water.
Face mask, depth and pressure gauges, oxygen tank, fins, and a watch and compass are the primary equipment that the diver has to wear before he goes under water for scuba diving.
