Diving is a very interesting and useful activity, but, as in any other sport, it has its own scuba diving safety rules, which are fraught with health.
Don’t think that if you’ve read the scuba diving forums and watched a couple of scuba diving movies, that’s enough to become a scuba diver and save on training.
Yes, of course, instructors and dive centers make money teaching you. But in return you get very valuable information and skills that minimize your risks when diving, If of course you have chosen an intelligent instructor.
If you are planning your scuba diving, you need to be aware of all the risks the environment can pose to humans. You may wish to consider my list of safety rules whilst scuba diving. They will help you avoid problems while you do this exciting activity.
Applying these rules in practice as well as good training will ensure the enjoyment of this sport with minimal risk when exploring the amazing underwater landscapes of marine life.
1. Never hold your breath underwater
One of the first and most important scuba diving safety rules of scuba diving safety. Ignoring this rule can result in barotrauma.
Oscillatory pressure in the lungs can rupture the walls of the lungs by holding your breath underwater at depth.
The regulator is designed in such a way that it supplies you with breathing air at a pressure equal to the ambient pressure. That is, on the surface, air will enter your lungs under pressure of one atmosphere, and at ten meters the regulator will supply you with air under pressure of two atmospheres. You will not feel it, because the same two atmospheres press on your whole body at this depth. But if at this moment you hold your breath and float to the surface, the air in your lungs will tend to expand twice. Your lungs won’t stand it, don’t check it! Just breathe continuously, deeply and evenly.
In some cases pulmonary barotrauma can lead to the release of air bubbles into the chest cavity, and later into the blood.This in turn can cause arterial gas embolism which is often fatal. If you breathe slowly and gently the above problems can be avoided, just make sure you maintain a consistent and regular rhythm.
Therefore, plan a dive within the no-decompression limits where you can complete the dive and return to the surface at any time of the deep dive at the lowest risk.
2. Check your diving equipment in the evening before a potential dive
It’s also very important to do.
About 15% of dive deaths occur each year due to equipment failure.
This could be avoided if divers inspected their tools more thoroughly before entering the water. Therefore, inspection of equipment is an indispensable condition for safe diving. Check that the air tank is completely full, that its regulator is working at full power by inhaling and exhaling.
Also check your buoyancy control device. Examine in detail how your release belt works and that you have the necessary weight. Always carefully check each piece of equipment to make sure everything is properly fastened and tightened.
You don’t need to have the most expensive equipment or dive computers from dive shop. The main thing is that it is in good working order, fully equipped, in accordance with the conditions of diving and your level of training. Be sure to check the performance of the equipment immediately before diving. Have your equipment serviced periodically by specially trained technicians. Use and store it correctly so that it will last you longer.
3. Always study the area and weather conditions for diving
Weather conditions, underwater currents and seasons can vary significantly even in the same place in the world’s oceans. The latter can differ significantly depending on the specific time period. This advice should not be abused, as it is extremely important for the safety of the dive.
Agree with your partner while on the surface what you will do underwater and where to swim. Repeat hand signals as needed. Familiarize yourself with the dive site. Agree on time limits, depths and air supply. Think about unforeseen situations and how you will get out of them.
4. Dive within your capabilities. Don’t be afraid to interrupt the dive
Diving is a difficult activity, so it requires a lot of knowledge and even more practice. Therefore, if you doubt your abilities, do not dive. All dives differ in their complexity due to depth, underwater landscape, water temperature and other factors. So never dive in if you have the slightest suspicion that it may be beyond your experience or capabilities. Your life and health can be seriously endangered.
Be honest with yourself. Evaluate your level of training, skills and physical condition objectively. If you feel that you are not ready for this dive – give up. It’s not stylish. It is better if everything is loaded and the stress will be felt during the download or the situation will get out of control.
Always make sure that your knowledge of the dive site is sufficient and sufficient physical training. Complex deeper dives require advanced certification in open water, cave dives – technical certification. access to deeper waters, you need to learn seriously.
If you realize that the dive is too difficult for you, stop it immediately. If you decide to stop the dive, be sure to let the attendant know.
5. Return to the ascend slowly and safely using safety stops
The key to safe ascent are your safety stops.
This is absolutely important that you ascend safely because if your rate of ascent is too fast then the pressure rises as you get closer and closer to the surface.
Even if during the dive you did not go beyond the no-decompression limits, but surfaced very quickly, that is, changed the ambient pressure abruptly, you again put yourself at risk of decompression sickness.
This means that the nitrogen that is absorbed by your lungs can form bubbles in the bloodstream and can lead to decompression sickness. Prevention is simple – just make sure you are climbing no more than 18 meters / 60 feet per minute(in other words, no faster than 30 centimeters per second), and ensure a safety stop for three minutes. Limit yourself to within your capabilities.
The closer you are to the surface, the slower you try to ascend. And make safety stop after every dive, especially if it was deep. To do this, safety stop at five meters for three minutes. Help your body get rid of nitrogen smoothly.
6. Check the sensors of your equipment and data of your dive computer regularly
You would be very surprised to learn how many divers get into trouble because they neglect to regularly check their sensors,data of dive computer.
This forces them to make an unsafe ascent without a safety stop that could cause decompression sickness.
Always keep in touch with your scuba diver buddy, who will be able to immediately inform you about the low level of your air tank(end of yours safety reserve) .
7. Check your health on the eve of the dive
It would be logical to make sure in the evening before the dive that there are no serious health problems or at least chronic rhinitis (sinusitis), sinusitis, otities or other problems with the ear and throat. These diseases are almost incompatible with scuba diving.
In the evening, make sure that you do not drink alcohol or other substances that change consciousness and are physically ready to dive. It is also not recommended to smoke at least 8 hours before the dive. The combination of alcohol or nicotine with diving is fraught with extremely unpleasant consequences
You need to be focused and ready for your underwater journey. This is extremely important for the safety of your life and health.
8. Don’t dive alone
The basic concept of recreational diving is that you dive with a partner(dive buddy). It is not only safer, but also more interesting and convenient. Also you can use buddy’s alternate air source , as well as additional eyes and hands in case of an emergency. Also, before diving, when checking your equipment with each other, he may find some problem in it that you did not notice.
He will help you put on your equipment, as, in fact, you and him, after the dive will have someone to share your impressions with. There are many more such explanations. Despite the fact that now in many certification agencies there are special solo diving courses that will allow for you to swim alone, after appropriate training, the vast majority of professionals recommend diving with a partner.
Having constant communication underwater significantly reduces the number of risks and ensures that you will always have outside help in the event of an emergency. If you are diving with people you didn’t know before, take the time to make sure they are safe to dive and follow them as you would like them to follow you.
Even if you are very confident, still do not ignore this important rule. Even then it is advisable if it is impossible.
9. “Scuba Rule of thirds”
This rule applies more to technical divers but it will not be superfluous for all divers. The essence of the “Rule of thirds” is that a third of the air should be used during the descent, the other to return.
The last third should be left in reserve for climbing. To avoid diving fatalities, follow this rule very strictly.
The value of each fraction is determined taking into account the volume of air consumed and the length of the underwater route. Always plan your dive and dive according to your plan.
10. Positive proper buoyancy on the site will help save energy
A diver who tries to stay on the surface of the water in excessive gear has a high chance of getting tired, and therefore will not be able to avoid any problems that may occur when diving. Therefore, it is critical to establish positive buoyancy on the surface. use of a buoyancy compensator and a weight belt during training. Whenever possible, train and update your skills often. You should always be aware of the dangers of scuba diving. If you have not been diving for a while, be sure to take the time to update your knowledge and skills before going scuba diving again.
Even if your practical skills have not changed, there may be new technical characteristics of the equipment you will use. Take a refresher course, learn about all the events that may have occurred since your last experience.
11. Don’t touch anything in dive site.
Do not touch anything under water. Leave the underwater world behind in the same way it was before you, so that other divers can also enjoy the ocean.
Many of the cute sea creatures may have teeth or spines. Many of them are poisonous, especially in tropical seas. Some of them are so poisonous that then there will be no one to tell your comrades about them.
Most of them do not show aggression and are engaged only in a defensive position. However, be careful and do not touch them. Be careful with corals as well. They can seriously injure you.
What is the most important scuba diving rule ?
All of the above rules are equally important to ensure your diving safety underwater. In conclusion, I just want to emphasize – never dive if you have not been properly trained, studied the conditions and maximum depth of the location.
