How to escape from sand - murderers?

Sand is deadly. Not some unsteady, and the most usual. The one that is filled up in children`s sandboxes. In what on the beach adults cheerfully play the fool. Of what fortresses and locks are under construction. Of course, it is not necessary with shout Sand - the murderer! to tear the hair. However to note risk sand nevertheless costs death.

The group of the American scientists led by doctor Bradley Moron warns about the threat proceeding from sand (Bradley A. Maron) from medical school of Harvard (Harvard Medical School). Subject terrible " sand; you see, quite strange. However, if to understand, there is nothing funny in it.

Doctor Moron became interested in dangers of sand in 1995 when worked as the rescuer at the beach in Massachusetts. Once there was an accident - sand filled up the little girl digging in a hole. Fortunately, rescuers managed to define quickly location of the victim and to organize for it air access. The child survived, and Bradley with the father Barry (Barry Maron) began the research.

In 2001 they received the first results for the three-year period article was published in the magazine of the American medical association (JAMA).

I Morona collected recently new data, united them with old, analysed and published in Medical magazine of New England (New England Journal of Medicine) work under the name Sudden death from - for the falling-off pro-cops in " sand;.

We will notice, researchers looked for information everywhere where it is only possible: in the print media, on the Internet, interviewed rescuers, witnesses and so on.

as a result of Morona over the last 10 years counted 52 cases of a collapse of the holes and tunnels which are dug out in sand in the States, Australia, Great Britain and New Zealand. Sixty percent of the victims - 31 persons - died while many others needed the help of resuscitators.

The age of the victims made from 3 to 21 year (average - 12 years). 29% - children of 10 years are also younger. 45 victims (87%) were male.

Most often filled up people on the bank of a reservoir, on the beach - 41 cases. The remained 11 cases took place near houses, for example, on building sites.

Openings in sand were, as a rule, dug out by the victim, her friends or relatives. Diameter of holes differed ranging from 0,6 to 4,6 meters, and depth - in the range from 0,6 to 3,7 meters.

Usually after an unexpected collapse of the victim were completely shipped in sand, actually without leaving any signs of the location on a surface that, clear, complicated searches. At the same time it was impossible to use the heavy equipment.

crash it was carelessly caused by a variety of circumstances, including digging - digging, construction of tunnels, jumps or falling in a hole.

We try to improve understanding of risks in situations which cannot be connected with danger to life at all, - Bradley Moron says. - When people are on the beach, all their concern about safety is concentrated in the direction of " water;.

On the immemorial question What to do? researchers say that the answer - common sense. Do not dig (and do not allow children) to dig holes more deeply, than knee-deep. And if you dug a big hole, watch that in it nobody fell down, and bury before leaving. To put it briefly, do not hide the head in sand. It is not done even by ostriches.
