One of the first things taught in certification class for beginner scuba divers is how to dive safely. If you want to enjoy your dive now and future dives is to learn and adhere to the necessary safety procedures.
Another scuba diving safety tip also seems to go without saying. You shouldn’t dive when you have a head cold, bad allergy, or other medical problems that affects your breathing.
Check with your physician to see any medication you are taking will impair you ability to scuba dive. If you are taking medication that may affect your judgment, scuba diving may not be the best thing you could be doing.
It is important to know how to use your equipment, practice using it until you can do it blindfolded. Visibility during a dive can range from awesome clarity to very fog-like, to even pitch-black.
The scuba diving regulator is made and designed to deliver air from the tank at the ambient pressure of the water – the same pressure of the surroundings. That is necessary for keeping your lungs operating properly during your dive. You can help let the scuba diving regulator do its job by not holding your breath as you ascent and descend.
Not only does holding your breath affect the operation of the scuba diving regulator, but it can also result in serious injury to your lungs. By holding your breath, you are blocking the ability to deliver gas at the proper pressure. The air in your lungs may fail to expand or contract, thus causing unsafe pressure on your rib cage and lungs. Holding your breath during a scuba dive can cause blackouts.
Keep your scuba diving regulator’s mouthpiece in your mouth. If the regulator is out of mouth you may be able to exhale slowly for a while, but can only do this for a short time.
A life-saving safety tip is-always dive with a buddy. You should practice with your buddy a series of signals so you can communicate essential information while you are underwater and in murky or low visibly conditions. You and your buddy should never be out of sight of each other.
Novice scuba divers sometimes lose their calm. Always try to stay calm during your dive. There are things underwater that may scare or spook you, such as sharks, moray eels, sediment stirrups, etc.
