It is with a feeling of great concern that we remember the tragedies of Bhapal, Chernobyl, Spitak, Neftegorsk, and Atlanta. The scale of these incidents went beyond the borders of individual countries. The human casualties that took place in these disasters resonated with heavy grief in the hearts of people all over the world. A disaster in the medical sense is a sudden, fast-acting event that is extremely dangerous to the health and life of people. The main medical consequences of disasters are the occurrence of a large number of victims, mental disorders in people, and a discrepancy between the urgent need for medical care and the possibilities for its implementation. The causes of disasters are natural disasters (earthquakes, floods, hurricanes, etc.), man-made (explosions, fires) and transport accidents. Every natural or man-made disaster brings great misfortune to people. If a person is not prepared for this misfortune, his entire way of life may collapse. People are accustomed to believing that misfortune can happen to anyone but them, so they do not prepare for it. And when trouble comes, it is impossible not to be horrified by the many injuries and damages. You need to prepare for such a misfortune in advance. Every member of your family should know what to do before, during, and after a disaster.
