One of the alternatives for the withdrawal of 12 young men and their coach trapped in a cave complex in Thailand is diving. This is the last option considered by rescue teams, at least for the moment, because of the complexity of the operation related to the group's inexperience.
If a cavity is not on the roof of the cave, or if the evacuation of the water does not work, the children will have to walk at least 2 kilometers with narrow and flooded sections, this which can take up to six hours with a precise diving technique. Even so, the group started to be trained for the opportunity.
The operation, according to specialized divers, is much more difficult than the traditional mode at sea. In the case of boys, all the more, because of local problems and limitations of the sea. ;team.
From age on – cave diving is allowed only from the age of 18, or 15 years with parental permission. At least four courses, which go beyond the requirements for recreational diving, must be made for the sport.
"It's a totally atypical thing, it's not a sports dive, it's a rescue," said Gabriel Vieira Costa, who claims to have already performed more than 500 dives.
19659008] According to Costa, there are different places in the world that are sought after for diving in a country. cave In Brazil, the city of Bonito in Mato Grosso do Sul is one of them. Florida, United States
The caves in these places are different from those where boys and coach are trapped. The experienced geologist and diver, Adriano Gambarini, says that there are usually two types of caves to dive. 19659010] He explains that there are those in which the person enters an underground river – this guy always had water in his cavity and is the most common.
There are also caves that have already been dried, but inundated with the variation of groundwater, such as those found in the United States. They remain inundated after the phenomenon.

"The Florida Caves, and some of Mexico, do not have this feature of a "pipe." It's a room, the person dives and has visibility, "says Gambarini.
The cave of Thailand is different because it is dry, it was hit by the rain in season, which makes visibility difficult. this does not help predict future problems – there is little or no knowledge of the place by other divers.
"Underwater diving is much more dangerous.If you are at sea and there is a problem, go up to the surface.What is the problem with a cave?" There is a problem You have to go back, all the way.Drica de Castro, a diver since 1992, explains that there are a number of modalities included in the type performed in a cave, which can be done by the group.
"The siphon is a pbadageway of a cave with dry channels, which has lower sections, and these are flooded," says Drica. "To progress there, you have to walk into the parts dry and "
According to her, the equipment is usually prepared in duplicate: two cylinders must be used for all problems, what is called" redundancy ". A cable can be used as a guide, or as a solution to return to the starting point of the path in case of emergency.

In order to realize this whole process so traditional, only with adequate training, which is not possible in the case of Thai boys because of the age and time to teach the procedure. Drica introduced some alternatives:
"The rescue of boys should place a lot of cylinders en route I do not know if they want a diver to accompany every child at all times, or if multiple divers will be on the course and will pbad one for the hand of the other, "he said." I am curious to know what strategy they will prefer. "
According to Drica, the # Age is a positive point, she says that children often rely more on instructors than adults, which can help keep their coolness.
"Children have more confidence in the diver than they can." they are rescuing. "The danger is that one of them panics, but their profile, being both athletic and children, makes it easier. [ad_2]
