Beware, contaminated area!
In flooded houses and household outbuildings it is neccessary
to clean and disinfect all surfaces and equipment: every
flooded object has a coat of dirt. The layer of mud is very dangerous
sediment.
Flood leaves
harmful substances behind it. Water from rivers, that
flooded the banks with great force, brings many harmful substances with
it and leaves them as dangerous sediment in the flooded
areas, in houses, on the streets, in the backyards
and gardens. It is also washes away well drains, trash dumps, carries
decaying plants and dead animals as well as toxic substances,
washed out of flooded factories, chemical depots, petrol stations and
oil depots. Therefore the flooded houses are considered to be polluted.
So, they need not only to be repaired and dryed, but, first of all, to
be cleaned with pure unpolluted water and decontaminated.
Flood pollutes
the wells. Flood water also pollutes and contaminates the
wells. Water from a contaminated well may contain bacteria or viruses,
that may cause diseases, such as typhoid, infectious hepatitis,
dysentery, diarrhea and others. Therefore never use the water from your
own well after the flood until it is inspected by sanitary and
epidemiological service. After the flood retreat all the
wells should be disinfected.
Drinking water.
The water is considered to be potable (drinking) if it was twice tested
by the sanitary and epidemiological service and was boiled.
During the first two weeks after positive check results it is better
not to drink the raw water but use only the boiled one. Remember: until
the sanitary and epidemiological service checked the water in your well
and found it to be suitable for drinking, drink the water that comes in
sealed containers only, theis water should be given to the animals too.
For washing and
cleaning use purified (decontaminated) water only. Remember: water
from contaminated well is not suitable for washing, laundry and
cleaning after the flood. Ask the specialists from sanitary
and epidemiological service, where you can get water for these purposes
in your locality. If there is no other way, use "technical" water.
Flood leaves
contaminated water and sediment in the house. After flood
has retreated many buildings still have water inside them - it can be
seen in low places such as cellars and garages, but it remains
invisible in various hidden wall and floor cavities or under the floor
in the basement. Flood water and mud that came with it promotes the
growth of mold and mildew brownie, as well as mosquitoes propagation.
Moisture can also cause damage to the structure of constructive
materials, especially wood and plaster, it nullifies the value of
thermal insulation, that failes to protect the house from heat loss
after it was watered.
 Remember
that health is more important than material benefits, therefore, throw
out everything that may create a threat. Every object in
the house, that was flooded with water, or was only splashed by flood
water or dampened by its evaporation, is considered to be contaminated.
Every object, that was watered by flood and can not be cleaned,
disinfected and dried, should be thrown out. No one of the indicated
actions (e.g., only drying or drying after cleaning) does not give the
required result if applied separately. It is a necessity, not an
advice. Those materials can not be used. Until all the items
are dry there exists mold hazard.
Disinfection is carried out in a number of steps to remove
microorganisms that cause rotting, or to restrict their
growth. The room should be cleaned as quickly as possible to
minimize the number of bacteria and to remove water and nutrient
sources they need.
Be careful: the
disinfectants are dangerous! Substances, such as
chloramines, calcium hypochlorite, chloride lime kill harmful microbes,
destroy fungus and mildew, as well as their spores. They are not safe
for humans too. If you are forced to carry out disinfection by
yourself, then follow the safety rules: provide sufficient ventilation
in the premises you are disinfecting, protect your airways by using
respirator or textile mask and wear protective gloves and clothing.
Adhere the recommended doses of disinfection sustances.
Thoroughly ventilate the room that has been disinfected. Never
disinfect the rooms in presence of the kids. In 24 hours wash
all the surfaces in the living rooms; this should be done especially
thoroughly in the areas where little babys will stay.
