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.
