  • ES at the federal level, when the number of victims exceeds 500.

The nature of the emergence of emergencies are:

  • Technogenic - caused by an accident, explosion, fireon a chemically hazardous site (for example, nuclear power plants), followed by the release of environmentally hazardous substances into the atmosphere, as well as substances that pose a threat to human life (radiation). Transport accidents, industrial accidents are also technogenic emergency situations.
  • Natural - are the consequence of natural elements,such as a hurricane, a tornado, an earthquake, a flood, an eruption of an active volcano, forest fires, landslides, snow avalanches. About how to act in case of fire in the forest, you will learn from our article What to do in case of fire

  • Biological emergency: epidemics with a high rate of spread and a large number of human casualties.
  • Social emergencies are the result of the activity of the society and are engendered by the society, including civil wars, world wars, terrorism, hunger, etc.

In terms of the speed of development, emergencies are classified into:

  • sudden - for example, a volcanic eruption;
  • rapid - associated, for example, with the spread of fire during forest fires;
  • moderate - floods, floods.

Causes of Emergencies
