In scale, emergencies can be classified intoLocal character - the emergency zone (the territory where the emergency situation was created and the living conditions of people are violated) does not go beyond the territory of the facility, while the number of victims (people killed or injured) is not more than 10 people, or the amount of material damage (the amount of damage to the environment and material losses) is no more than 100,000 rubles;Municipal nature - the emergency zone does not go beyond the territory of one settlement or the inner city territory of a city of federal significance, the number of victims is no more than 50 people or the amount of material damage is no more than 5 million rubles, and the emergency can not be attributed to an emergency situations of a local nature;Intermunicipal character - the emergency zone affects the territory of two or more settlements, the inner city territories of a federal city or inter-settlement territory, with the number of victims not exceeding 50 people or the amount of material damage is no more than 5 million rubles;Regional character - the emergency zone does not go beyond the territory of one subject of the Russian Federation, the number of victims over 50 people, but not more than 500 people, or the amount of material damage is more than 5 million rubles, but not more than 500 million rubles;Interregional nature - the emergency zone affects the territory of two or more subjects of the Russian Federation, with the number of victims over 50 people, but not more than 500 people, or the amount of material damage is more than 5 million rubles, but not more than 500 million rubles;Federal nature - the number of injured more than 500 people or the amount of material damage is more than 500 million rubles.According to paragraph 2 of the Decree of the Government of the Russian Federation of May 21, 2007, No. 304, which established this classification, it does not apply to emergencies arising from forest fires.Stages of emergency development 
ES of any type in its development are four typical stages (phases).The first is the stage of accumulation of deviations from the normal state or process. In other words, this is the stage of the emergence of ES, which can last for days, months, sometimes - years and decades, and in the case of earthquakes and volcanic eruptions - a century.
The second is the initiation of an emergency event, which is the basis of the ES.The third is the process of an emergency event, during which the release of risk factors (energy or substance) that adversely affects the population, facilities and the environment.The fourth is the stage of attenuation (by the action of residual factors and prevailing emergency conditions), which chronologically covers the period from the overlap (restriction) of the source of danger-the localization of an emergency situation, to the complete elimination of its direct and indirect consequences, including the entire chain of secondary, tertiary, etc. consequences. This phase for some ES may start on time even before the completion of the third phase. The duration of this stage can be years, or even decades.
