People with a hunger for excitement are often taking on one adventure or other. Be it rock climbing or shooting down the rapids in a canoe along some river, they constantly seek out physically demanding activities and even danger. Most of the potential dangers may be averted through adequate preparation and training. One of the most alluring and potentially frightening activities sought out by many is underwater diving. This can take the form of scuba diving or snorkeling, each of which requires its own set of equipment and instructions. Scuba diving can take top-notch swimmers into the depths of the sea by equipping them with oxygen tanks and a wet suit. Snorkeling allows competent swimmers to explore more shallow areas, such as a reef. In either case, extreme caution is required. The sudden loss of oxygen is probably the biggest threat. Should the diver`s tank suddenly lose pressure, get damaged, or even become lost, they must immediately surface or risk drowning. It is also possible for a snorkeler to be suddenly cut off from their oxygen supply and necessesitate a mad dash to the boat or shore. It is essential for the diver to check the tank prior to going underwater to see that it is functioning properly and then to keep tabs on it while diving. A simple kink in the line could spell disaster when down below. Another danger to be careful of for divers is the bends. Submerging or surfacing too rapidly are the cause of this condition in which higher-than-normal levels of oxygen enter into the bloodstream and wreak havoc on the circulatory system. The bends can be deadly if they are not properly tended to immediately. Always bring a diving buddy along and it would also be a good idea to keep someone in the boat above while diving so they can get help in the event of an emergency. Great Whites and other sharks are considered by many divers to be the greatest danger, both mental and physical. Great Whites can reach lengths exceeding 20 feet. They have shown a propensity to attack, dismember, and even kill people. Clearly, it is a good idea to give these animals as much space as they need so check before heading out and avoid all known feeding grounds. The stings of both eels and jellyfish are also known to be dangers best avoided when diving. By. Zak Breezer

A few comments on your Diving Dangers blog that you may wish to correct.

Its a Scuba Cylinder or Tank, not an oxygen tank.

It is not excess oxygen that is a problem with bubbles in the blood stream as most all the oxygen is used in the body, it is the excess nitrogen.

These things aside it is good to keep in mind the risk that we take in diving and mitigate this through education, training and diving within our personal limits.
