A flood is a significant flooding of an area resulting from an increase in water level of a river, lake or sea during the period of snow melting, rain showers, wind seiches, in case of blockages, ice jams and so on.
Floods caused by wind seiches in river estuaries belong to a special category. Floods lead to a destruction of bridges, roads, buildings and structures, cause significant material damage, and, at high speeds of water movement (over 4m/s) and a high water rise level (over 2 m) lead to deaths of people and animals. The main cause of destruction is the impact of hydraulic blows of water masses, blocks of ice moving at a high speed, various debris, floating crafts, etc. on buildings and structures. Floods can arise suddenly and last anywhere from a few hours to 2-3 weeks.
AT THE RISK OF A FLOOD IT IS NECESSARY TO:
· listen to information about the situation and operational procedures on a continuing basis
· transfer food, valuable items, clothes and shoes to upper floors
· evacuate people from hazardous areas
· rescue people, wherever they happen to be, using any means
· first of all, move children out of the flooded zone
· render urgent help to people who are in the water.
ACTIONS PRIOR TO ES:
If you are at home:
· Stay calm.
· Warn neighbors and help children, the elderly and the disabled.
· Listen to the radio in order to receive updates about developments in the emergency.
· Do not call anywhere to avoid overloading telephone lines.
· Leave the house as soon as you receive the order to evacuate from rescue services.
· For evacuation, use the route established by the rescue services. Do not try to shorten the way – you can land in a dangerous place and become trapped.
· Secure domestic animals; provide them with water and food.
· Take only essential items (first aid kit, documents, medication).
If you are in a car:
· Avoid driving on a flooded road – you may be washed away by the current.
· If you find yourself in a flooded zone and the car breaks down, leave the car and call for help.
ACTIONS AFTER ES
· Take out a first aid kit, help the injured.
· Listen to the radio and follow the instructions of rescue services.
· Be careful when returning home. Check whether its structures (walls, floor) are safe.
· If you discover a puddle of stagnant water in the house, immediately pour it over with 2 liters of a bleaching solution. Do not drain all of the water at once (this can damage the foundation) –drain only about one-third of the total amount of water every day.
· Do not live in a house where stagnant water remains.
·Watch out for an electric shock – if the water layer on the floor exceeds 5 cm, wear rubber boots.
· Make sure that electric cables do not contact with water. Turn off the power supply on switchboards in flooded areas, if you have not yet done so.
· If the floor near the switchboard is wet, cover it with a dry board and stand on it. To turn off the power supply, use a dry stick.
· If you have suspicions that drinking water in a well or a standpipe is contaminated, use water that has been stored in bottles in advance or boil it for 5 minutes. You can also add 2 drops of a bleaching solution to 1 liter of contaminated water and then let it stand for 30 minutes.
· Wash or disinfect all dirty dishes and tableware using boiling water or a bleaching solution (one teaspoon of bleacher per one sink filled with water).
· Do not raise air temperature at home above 4 degrees Celsius before all standing water is drained.
· Remove all debris and objects soaked in water from the house.
· Remove remaining mud and dirt, throw away all soiled bedding items, clothes, furniture and other objects.
· Wipe all surfaces in the house with a bleaching solution. At the same time, ensure good ventilation to purify air from toxic vapors.
