Flood prone areas

A flood is the more or less quick immersion of an area under varying water levels.
It is caused by heavy rains


  • Find out about the warning signals and evacuation procedures
  • In case of imminent flood risk switch off heating appliances, gas and electricity
  • Move your furniture, electric equipment and other personal effects to upper floors
  • Put toxic substances, such as pesticides and insecticides, in a safe place so as toavoid pollution


  • If you are indoors:
  • Keep calm
  • Warn your neighbours and help particularly the handicapped, children and the elderly.
  • Remain Alert of the danger and its evolution. Listen to the radio
  • Do not use the telephone, don't overload the network
  • Leave your house as soon as those in-charge of the emergency operations request you to
  • Use the route indicated by those responsible. Do not take short cuts, you run the risk of finding yourself trapped or in a dangerous place
  • Make the necessary arrangements for domestic animals
  • Take with you only what is absolutely necessary (first aid kit, identity and personal papers and medicines)

If you are in a car

  • Avoid driving on a flooded road as you risk being swept away by the current
  • If you are trapped in a flooded area and your car breaks down, leave it and get help for you and your passengers


  • Help the injured. Bring your first aid kit
  • Listen to the radio and follow the instructions of those in charge of the rescue operations
  • Be careful before entering your home. Check that it is structurally sound (strength of walls, floors, broken window panes and other dangerous debris)
  • Immediately pour about 2 liters of bleach into stagnant waters
  • Do not drain all the water in one go (this may damage the foundations)
  • Clear only about a third of the volume of water per day
  • Do not live in a house in which there is stagnant water
  • Watch out for electric shocks. Wear rubber boots when the water level is higher than 5 cm above the floor
  • Make sure electric cables do not come into contact with water. In flooded areas immediately switch off the current at the mains, if you have not already done so
  • If the floor near the main fuse box is wet, step on a plank so as to be on a dry surface and use a dry stick to switch off the current
  • If you suspect that the water meant for consumption has been contaminated, use bottled water or boil the contaminated water for 5 minutes.
  • You can also add three drops of unscented bleach per liter of contaminated water.Let it rest for 30 minutes before consuming it
  • Wash or sterilize contaminated crockery or utensils. Use boiling water or a sterilizing solution (approximately a coffee spoon of bleach in a sinkfull of water)
  • Do not heat your house at above 4 degree Celsius before all the flood water has drained away
  • Empty the house of all dirty and soaked material and debris
  • Remove the remaining mud and earth and discard contaminated furniture, domestic appliances, clothes and bedding
  • Clean and wipe all surfaces and structures with bleach.
  • Ensure there is a good draught to clear away the fumes
