Good preventive
maintenance can reduce the risk of a problem with molds growing inside
the home and other buildings. Homes with water damage
should be repaired and all moldy material should be removed. Some
causes and contributors of high humidity may include leaking pipes,
water
damaged dry walls and ceiling tile (due to leaking pipes, leaking
roof or flooding), faulty or obstructed dryer vent connections, use
of steaming hot water in washing machines, many showers, faulty or
obstructed bathroom/kitchen ventilation fans, boiling water for long
periods of time, canning or pressure cooking, hand washing and rack
drying knit and delicate laundry, use of humidifiers and excessive
sealing of the home so that there is inadequate air exchange.
The most important
consideration to keep in mind is that mold needs a moist, wet, or
damp environment in order to thrive. By maintaining
a clean, dry home or workplace, dangerous mold species cannot begin
to grow. Sources in and around homes that can create a dangerous
environment include leaky or broken pipes, windows or older doors
that lack good
seals, roofs that leak, and any cracks or holes in the building.
If flooding has occurred, it is extremely important to make sure
that
the water is thoroughly dried up to avoid festering water or dampness
within 24 to 48 hours.
Some molds can be killed by cleaning the moldy surface with chlorine,
(few) however, stachybotrys often has a germ mycelium that is buried
inside the water damaged surface that is often inaccessible to chlorine.
In fact, bleach often does not kill Stachybotrys entirely when directly
applied to it. Changing the humidity may lead to limited death of the
stachybotrys colony. However, changing the humidity may also induce
heavy sporulation. Burning the building that has undergone stachybotrys
contamination has been an idea of many people but some experts state
that not even a fire of 500 degrees could destroy the spores of this
deadly enemy. If anything, it could spread it and worsen the condition.
The ground around these buildings can also become heavily contaminated
with stachybotrys from a sick building. It is recommended that the
ground (dirt) be removed at least one meter prior to rebuilding any
new foundation.
To avoid such problems before a potential catastrophe, all buildings
should undergo scheduled maintenance that includes inspection for water
leaks, problem seals around windows and doors, as well as checks for
visible mold in moist or damp parts of the building.
There are air sample,
tape, swab, and DNA tests that can be done on any premises to determine
if stachybotrys is present. Because stachybotrys doesn't spore the
same way other toxigenic molds do, it does not show up in a standard
blood antibody test; therefore, serum tests are not very
accurate. There are some other
tests to
determine stachybotrys exposure. CLICK
