Scuba Diving comes with a few rules to keep you safe. During your Open Water course, you will learn a lot of rules about scuba diving. When I teach the PADI Open Water Course, there is 6 rules that I absolutely want my students to remember before I can certified them. So bookmark this post full of good sense!
Are you ready to become a scuba diver? Do you want to go further into your training?
1. Breathe continuously while on scuba. Never hold your breath.
There is no way, you would have missed that one. Each instructorwill repeat, repeat, repeat and repeat again! For a very good reason, holding your breath when you change depth, even a little, could cause an overexpansion of youlung. If that happen the symptoms are short breath, difficulty of breathing, pain, unconsciousness, you should give oxygen and call emergency.
Beside the risk associated with holding your breath, a good control of your breathing helps you to maintain a proper buoyancy. That’s where diving become relaxing.
2. Equalise early and often while descending. Never go deeper than you can comfortably equalise.
It is common sense, but many divers forget this rule and takethe risk to burst an ear drum. Bursting your ear is already a problem, but if it happens underwater chances are you will get disoriented enough to loose your regulator and drown. So if you have issues equalising, take your time, use a rope to control your descent, go feet first and never go down when it hurts.
Talk with your instructor about different way to equalise. Not everybody can do it the same way. Also, if you have a cold or congestion, do not dive. The ocean will still be there in a couple of day.
3. Ascend slowly from every dive and make safety stops.
This rules is directly linked to Rule number one. Going slowly will save you to overexpand your lung. But also, it is made to reduce decompression sickness risk, caused by your body absorbing too much nitrogen. By doing a safety stop between 3 and 6 meters, you let time for that excess nitrogen to escape your body. Recreational divers should always do no decompression dives so they can come back to the surface at any point, doing a safety stop force you to slow down and reduce most of scuba diving risk.
A diver at 15 feet of saltwater, typically, can stay indefinitely with almost no chance of decompression sickness while a diver at 60 feet can only remain for about an hour before needing to stop and decompress prior to direct return to the surface.
If you had but 30 seconds to teach someone to scuba dive, what would you tell them? The same thing Mike did — the Golden Rule of scuba diving. Breathe normally; never hold your breath. The rest, in most cases, is pretty much secondary.
This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.
There is an old and questionably reliable rule, known as the “120 Rule” that says if you subtract your max depth from 120, you'll get your no-deco time. So an 80-foot dive gives you 40 minutes before it's time to head back to the surface.
PADI tables have a special rule called the WXYZ Rule: If the Pressure Group after a dive is W or X, the SIT should be at least 1 hour. If the Pressure Group after a dive is Y or Z, the SIT should be at least 3 hours.
In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments.
How deep can you dive without decompression? Practically speaking, you can make no stop dives to 130 feet. While you can, in theory, go deeper than that and stay within no stop limits, the no stop times are so short that "well within" limits is essentially impossible.
I read an article that said because decompression illness can cause subtle but lasting changes in the circulatory system, doctors recommend that someone who has suffered the bends never dive again.
The depth most commonly associated with the term safety stop is 15-20 feet (5-6 m). Divers are taught to remain at this depth for at least three to five minutes, as it allows the body to offgas nitrogen accumulated in the tissues while at depth.
Commonly referred to as the ABC's pre-dive safety check system, the letters refer to air, buoyancy, and clips. Confirm that the primary regulator and the backup are working well. Take your buddy through the process of removing the backup air supply. Buoyancy checks confirm you'll have good buoyancy once in the water.
For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment.
The three Basic Rules of Scuba stated in the proper order of importance are: Breathe continuously, ascend slowly and maintain control, and never dive alone or beyond your level of training.
In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments.
