Hydrodynamic accidents

A hydrodynamic accident is an emergency situation caused by the flooding of a large area with an out-of-control mass of water due to the collapse of a hydro-technical installation or part of it. Potentially hazardous hydro-technical installations include reservoirs, dams, large canals, sluices, etc.

The collapse of hydro-technical installations can occur as a result of natural disasters or the impact of human activity.

Natural disasters that cause hydrodynamic accidents:

- earthquake;

- hurricane;

- avalanche;

- landsliding;

- floods.

Types of human activity that cause hydrodynamic accidents:

- defects of structural elements in hydro-technical installations;

- violation of the operating rules of the hydro-technical installation;

- release of a small amount of water by the device and an overflow of water over the dam;

- excessive water flow;

- failure of culverts.

Dangerous consequences of hydrodynamic accidents:

- destructive wave;

- local flooding.

The population living in areas of possible disaster and dangerous flooding of hydro-technical facilities should know the rules of safe behavior during hydrodynamic accidents.

Rules of behavior in the case of hydrodynamic accidents:

- determine in advance several possible short routes to climb to higher areas;

- have an emergency pack handy with a certain amount of food, water, medical supplies, important documents, money, flashlight and warm clothes;

- disconnect electrical and gas appliances, close doors, windows, and ventilation systems;

- release pets;

- go to a higher area that you have already determined.

If overflow occurs suddenly:

- climb to the attic of the house, to the upper floor of the building;

- stop the electricity supply, inform the rescuers about your location with color or light signals;

- prepare a supply of food and drinking water;

- do not use food products that have fallen into flood water;

- you can leave the flooded area independently if there is a need for emergency assistance or if the water level rises rapidly and there is no hope for rescuers to arrive.

If you fall into water:

- get rid of tight and heavy clothing to move comfortably in the water;

- keep sharp and cutting tools away from you;

- hold on to non-sinkable items that allow you to stay afloat until help arrives.

What to do after a flood:

- when the water recedes, it will be possible to return home only after permission from the relevant institutions;

- when you return home, do not turn on the gas and electricity supply systems without making sure that they are in order;

- to prevent the spread of infectious diseases, quickly collect the garbage brought by floods and clean the yard and the house;

- use the source of drinking water after a proper sanitary inspection.
