Pointed out by experts as the most recent and riskiest option to save the 12 boys and football coach arrested since June 23rd at the Tham Luang cave complex in northern Thailand, diving snorkeling, called scuba diving, can become the only viable way to save them, if the rains fall again hard in the area
Diver dies during the rescue of the cave of the boys
Among the many factors that can dive into the cave more complicated even for experienced divers, some found in Tham Luang can turn the production of boys into an even more complicated task.
"The water is muddy because it brings sediment from the rain, the cave has a lot of narrow tunnels," said Rodrigo Severo, a member of the Speleorresgate Committee of SBE (Brazilian Society of Speleology).
Equipment limitation
In a possible dive rescue, boys may wear full masks, which allow the diver to breathe through the nose rather than through the mouth, as with normal masks that cover the nose and the eyes. In addition, this type also allows radio communication.
"They received full masks, which helps a lot to breathe and communicate with the divers. There will also be air tanks. explains Severo.
This type of mask is generally used by professional divers, such as those who work on oil rigs, wreck rescues,
Calm under pressure
According to the Brazilian, dive into the caves is a complicated modality even for those who have hours of training. In very small spaces, such as tunnels in the Tham Luang Caves, the task becomes even more difficult.
"Very experienced people should be removed from the caves because they are very complicated physically and psychologically.It is very easy to stop breathing properly through the mouth, to do too much effort, to stress. That can cause a tragedy, even more so in their case, that has been trapped underground for so long. "
When it becomes unavoidable to put respirators and masks on boys and make them through a series of flooded tunnels about 30 meters inside the cave, each of the boys must be accompanied by at least two divers.
most of them do not know where to swim, the ideal is to focus on the part of the breath and only .I would not put fins.After what I saw, the plan seems to involve a diver trained in front and boy to of it, sharing the same reservation It would be guided by the rope, we always had a rope guide to find the way in the caves, "illustrates Severo.
The current, on the other hand, can be an ally, according to the diver: "How are they going to swim? to encourage the current to stop, it helps, it decreases the energy expenditure. For divers, getting in the stream is the best because it is safer. And when it's time to leave, it's easier for everyone, rescuers and victims. "
