Diver training requires following the rules

Текст статьи:
Diving to great depths may bring unforeseeable situations. Divers should descend with one partner at least in order to react to equipment faulty, injuries and so on, belay one another or provide first aid in the situation becomes serious. Air supply must not stop and you need to get to the surface as quickly as possible following all the rules of a safe and appropriate surfacing. It is required to go through a diver training with experienced instructors on dry land, only then should you carry on to practical lessons in water.
Situation 1: second stage regulator failure
An emergency usually occurs at the time of diving into caves with narrow entries. Sloppy movements may lead to equipment hitting the stone surface. If one of the divers has a regulator failure he should use the octopus and compensator of his partner. When the diving equipment was not that perfect divers had to breathe in the breathing gas in turns, until they reached the surface. They even managed to surface from great depths.
Situation 2: intake valve on compensator is not working
This problem is not as difficult to solve as it seems. Such situations were successfully resolved two decades ago. What do you need to do? You should detach and reattach the feeding hose a few times. If this doesn’t help to fix the failure, you can try to inflate the compensator with your mouth.
Situation 3: inflation hose is not connected to the device
The hose needs to be back in place. But it sometimes happens that the valve at the end of the hose is jammed and the air is streaming out of the cylinder with sound. This may occur when there were repeated attempts to reattach the feeding hose to the intake valve.
Situation 4: cylinders slipped out the clip
Many divers fasten the cylinders to compensators with the help of plastic clips. They are very convenient to use, but plastic has its disadvantages. Cylinders may slip out the clip while plunging into the water as well as at the time of surfacing or getting in the boat. In order to prevent this one needs to check that the clip is ok from time to time.
If everything is developing in an unpleasant scenario, you can try and take off the compensator and properly install the cylinders. But if you have a partner with you, than he should deal with this responsible task. Your partner is will have to catch the slipping cylinders with his knees. He will use his hands to fasten the straps.
But it is important to inform you partner in trouble about your helping intentions. Your unexpected actions behind your partner’s back may cause confusion and sometimes even panic.
Coherent performance requires practice. It is important to not only have all the skills and knowledge, but also know your partner’s character peculiarities and foresee all his possible intentions. Otherwise there is a chance of misunderstanding when you all do different things at the same time. When you have only got seconds the right actions is what makes the difference between the life and death.

Diver’s note: to drink or not to drink?


People see drinking alcohol as an ancient national tradition. Can you still follow it when you dive 30 meters deep and even deeper?  This very question causes much controversy among those who are really keen on diving.
Is it possible to combine diving and alcohol without any risk of damaging health? The answer seems obvious. What is more, recommendation to restrain from alcohol before and after diving was not just made up. Alcohol is forbidden by the PADI standards.
Does the amount of alcohol matter at the time of diving? It definitely does. When a person drinks a bottle of vodka, he loses his coordination and ability to think rationally on dry land to say nothing of the depths of the Red sea. The situation with such high dose is quite clear.
What if we consider just a can of beer or a shot of vodka? Such a dose does not cloud reason, the reaction remains adequate, a person is still able to put on the equipment and pay attention to what instructor says. Everything seems normal but unfortunately it is so only on the outside. The body is already experiencing an insignificant degree of dehydration. This very physiological state is very dangerous for a diver. One of the dangers is decompression sickness that is familiar to many diving beginners. To be safe one needs to pay close attention to his or her health and listen to the advice and directions of instructors at the time of diving training.
It is no coincidence that a person feels harrowing thirst during a hang-over, because any kind of alcohol dehydrates the body. When it happens of dry land, it is noting critical. When it happens under water different rules apply. A dehydrated body under water has a strong chance of developing a decompression sickness.
Experienced diving instructors always recommend drinking a lot of liquids at the time of training. Water thins the blood and provides its normal circulation. Intensive drinking regimen – is a golden rule of a safe diver. It needs to be mentioned that for a person who drank alcohol recently or in the very day of diving this is less effective. The risk of having a decompression sickness after drinking alcohol for a diver increases drastically, even if all the safety norms and surfacing rules are precisely observed.
One more question that is really important to divers is whether it is acceptable to drink alcohol after diving and if so, how much is allowed? You shouldn’t grab a beer to celebrate a successful dive having just stepped out of the water. At that moment the process of retaining B.U.N from the body is not yet finished. That is why any factors that cause blood thickening (alcohol) may provoke decompression sickness. If it is impossible to completely avoid having a drink at the day of diving than is should be put off. The first safe drink of alcohol a diver can have only 4-5 hours after the surfacing.
