Safety on Diving

By Aviv Lahat 

Every ordinary person understands that a high level of safety is required for diving. The reason for this is that we are humans, creatures of the land, which can not exist without the provision of air to breathe. We want to dive in a safe and enjoyable way. We must invest as much effort as we can in this way.

We need to understand that we have to be fit to hold the dive, we carry a wide range of equipment, make sure they are working properly, and plan our dive carefully. 

Eligibility for diving

Before diving, I have to ask myself: Can I do this dive?

The conditions required of a person planning to dive are good and good sleep, drinking plenty of water in the 24 hours before diving, prevention of drinking alcohol and drug consumption (regardless of diving but the effect on diving is destructive and dangerous).

A competent, worthy and professional partner will be one of the things I will never swallow without them. I will only ever be with a man I trust to dive with the people I care about.

Diving Equipment

We take on a large number of items of equipment so that we can exist underwater. These items must be carefully checked before diving and be eligible for  

If a hydrostatic test is necessary for the tank with which we are diving, we must ensure that the test ring is present on the tank. Visual testing is not required worldwide, and therefore only in specific countries is there a duty to perform this test. A visual inspection is indicated by a sticker that contains the month and year of the test. Often, the sticker can not be found. Mainly in containers belonging to clubs. A full container is a container in its possession 180bar / 2700psi .

We have to check that our air supply system is sealed and there is no faulty pipe that could break into the dive. In addition, one of the critical things in testing an air supply system is the mouthpiece. An abnormal mouth can scuba dive and cause an emergency during the dive.

Check the opacity of the balance by inflating it and inserting it into a water pool. The test is designed to show that there are no leaks from the balance, both the buoyancy and the inflator. An additional check we make for the balance sheet is an examination of the integrity of the buckles and the arms of the tank. An abnormal balance can be life-threatening during a dive and we must make sure it is proper and proper and  

We need to make sure that the barbs are normal and the buckle does hold the strap well. In addition, the weights must be fixed to the strip without moving. An abnormal weight belt may fall from the diver and cause too rapid a rise to sea level. As we know, this is a life-threatening  

 Mask, fins, and suit are the first accessories we will feel in our bodies. We must check that the straps and buckles of fins and mask are intact without tears. A fin that falls during a dive leads to an uncomfortable or enjoyable dive. A torn and improper suit will cause us not to feel warm in the water and therefore it is recommended to check that the suit is complete, normal and without tears.

After all these tests we have to put the complex equipment in the water pool to make sure there are no leaks and air will not be wasted for nothing . After investigating leaks of our scuba gear came to the important part, interests, and safety of all diving: Diving design!

More than once the question came to me: “ Is a 45- meter technical dive more dangerous than a 20- meter sports dive ?” The overwhelming answer is that technical diving is overwhelmingly safe from sporting diving. The reason is careful dive planning!

In planning a dive, we must make sure that we know the dive route in the best possible manner. If we get lost but we are with our partner we have to understand before diving what to do.When we reach the desired destination during the dive, how long will we stay there? A thorough introduction to our dive computer gives us the option to design a high-quality dive that will directly affect our enjoyment of diving. No-decompression time is a key ingredient in planning the dive, we must prepare accordingly and to know where the above figure appears in “to your dive computer in our possession. In sports diving we do not exceed this time, the recommendation is to go up when we notice that our dive computer is warning about 5 minutes before decompression. If we have exceeded this time, we must extend the safety parking by 5   The parking time will be proportional to the amount of air in the tank and without endangering any diver in the air.

The amount of air in the tank to return to the entry point is essential. We must summarize and make sure that we all know the pressure gauge we have and inform the partner if we reach the air quota that we agreed in advance. We must plan to have enough air in an emergency. That is to say, if we are at the deepest point of the dive and have to help a friend who has a problem with the air supply, I will have to carry enough air to get it safely out of the water. In the above case, safety parking is canceled.

Cases such as losing a partner during the dive should talk to the partner and they must agree on what to do in this situation. Other problems, such as pimping problems or equipment problems, should also be discussed. The couple must agree on the solution to these problems and realize them when necessary.

Safety parking is a recommendation only. We make sure to apply this recommendation during deep dives from 9 feet / 30 feet.

What do you do when you skip the dive program?

First, we have to stick to the dive program, second if we have to talk about it before diving. For example, if I have exceeded the depth of the dive ( I designed 25 meters and dived to 30meters ) I have to take into account additional variables such as air intake, deep intoxication, and time to rise to sea level. All this must be discussed before diving with your partner for diving.

After planning the dive it is time to wear diving equipment, not yet wearing the equipment an important recommendation is to drink plenty of water! This significantly reduces the chance of decompression and the air we breathe is dry air and we do not want to feel thirsty during the dive.

The signs of communication for diving are an existential necessity. This is one of the reasons why divers are lost on a dive or do not reach the maximum extent of diving with partners with whom communication is poor. You must coordinate the signs of communication before diving.

Wearing equipment should be done in the following manner: one diver wears all the equipment and then the second diver. The reason for this way is mutual help for the partner since wearing equipment is not a simple thing at all.

While wearing the equipment we need to keep the weight belt buckle that comes from the left, all the pipes are arranged in the right direction and cumbersome one another, buckles and straps tight balance sheet closed on the hull, Octopus pipeline comes under the right hand nor interfere with the free movement of the hand, The pressure gauge is accessible to the diver without any problem , A pipe comes over the left hand and easy access to the diver .

After wearing the equipment we will want to check our diving partner

Checking the couple is made in the same way in which we put on the equipment, tested and checks, not together!

We must make sure that the tank faucet is open to the end. If we hesitate, we can take a look at the caption on the faucet.

Then we must check the presence of a full tank, over 180bar /2700psi.

Properly checking the inflator, inflating and emptying all its imperfections.

Checking for the seconds ( first and octopus ), airflow in a convenient and easy way by pressing the demand button. There are even those who choose to breathe from their spouses’ air supply and check their health.

Check that the weight belt is in place and the buckle does come from the left side for easy and quick release when necessary.

After these tests, you should look at the pressure gauge and make sure that there is no pressure drop in the air supply system, we often encounter confusion about the direction of the faucet opening.

 The article above “the written order that we can get into the water without any fear, we understand the implications of small details dive and we can arrange situations where we may encounter during the dive and we can dive safe and fun!
