Safety during flooding events


Flooding occurs when water overflows its normal channels such as streams and storm water drains. Floods may also occur when there is an accumulation of water by drainage into areas which are not normally submerged.

Flash floods are usually associated with severe thunderstorms. However a storm may be upstream and might not be visible from your position, In the case of widespread flooding, which normally develops over several hours or even days, it is the prolonged nature of the rainy spell which gives the signal for possible floods.

Health hazards resulting from contaminated floodwater

Provided you follow health and hygiene advice the risk of contracting infections from floodwater is low. However, if you do become ill, seek medical attention as soon as possible. Most public water supplies will not be affected by flooding. Where mains water is contaminated, the Water Company will issue a notice telling you to boil your water.

If electrical equipment gets wet

If the interior of your house floods, do not use electrical equipment until you are sure it has dried out thoroughly. Before using your electricity supply again, have it checked by an electrician.

What about traffic?

Vehicles passing through floodwater may cause waves forcing water to enter homes. People should avoid driving through floodwater unless absolutely necessary. If it is essential, you should go slowly (below 10 mph) to avoid making waves.

What do we do if we have to move out?

Do not position a house, store-place, nor a campsite, caravan or a vehicle near a watercourse. If your property is at risk it would be sensible to consider alternative arrangements for yourself, personal belongings and any pets, and, most people will no doubt be able to make their own arrangements.

Precautions if flooding looks likely:

  • Put home emergency pack in a safe, accessible place.
  • Protect doorways and low level vents with sandbags. Make enquiries as to the availability of sandbags in your area, you may find it prudent to maintain your own supply.
  • Move valuables, food and other possessions upstairs where possible.
  • Turn off gas and electricity if flooding is definitely about to happen.
  • Assume that flood water contains sewage.
  • Ensure that you wear gloves when handling affected items.
  • Thoroughly disinfect and dry affected household items.
  • Before crossing a river, either on foot or in a vehicle, check whether the water level is rising. This is especially necessary if it is already raining, but remember that there could be a storm further upstream and floodwaters could be on the way.
  • Move to higher ground when flooding is possible.
  • If trapped in flooding in a vehicle, rather abandon it and climb to higher ground. It can be dangerous to try and drive out of the water to safety.
  • Protect/relocate stock and equipment on commercial/industrial premises.
  • In rural areas protect/relocate animals to a safe place on higher ground.

How to cope after a flood - some dos and don'ts:

  • DO Call your insurance company. Tell them what has happened.
  • DO check the Yellow Pages under Flood Damage for suppliers of cleaning materials or equipment to dry out your property.
  • DO contact the gas, electricity and water companies. You'll need to have your supplies checked before you turn them back on.
  • DO open the door and windows to ventilate your home. It takes a brick about 25mm/a month to dry out. Remember to unblock your airbricks and doorways, but take care to ensure your house is secure against intruders.
  • DO watch out for any broken glass or nails while you are cleaning up.
  • DO wash taps and run the water for a few minutes before use. Mains tap water should not be contaminated but check with your local water company if you're concerned.
  • DO NOT Turn on any electrical equipment until you are sure it has dried out.
  • DO NOT allow children to play in floodwater areas and wash children's hands frequently. Disinfect floodwater-affected toys before allowing them to be used.
  • DO NOT use food that has been in contact with flood water.
