Dust
Mites and Dust Mite Encasings and Covers
What are the best dust mite covers for you and do you really
need them?
By Mercia
Tapping
Our new
staff has been turning to me for guidance as to what to recommend
to our customers about dust mite encasings and covers. This
is the essence of what I tell them and I try to keep it very
simple.
Be clear
as to whether you have dust mite allergies. You do this by
going to an allergist for allergy tests.
Once you
have discovered you have allergies to dust mites, figure out
whether you have exposure to them. You are more likely to
have dust mites in your home if you live down South in warmer
climates or where there is a higher level of humidity. You
can test out whether you have dust mites in your home by using
a home
test kit.
You can
give yourself a break by cleaning your bedroom. See a past
article on the Dust
Free Bedroom.
A pillow
collects up to 2 pounds of dust mite feces [the stuff you
are allergic to] over a 2-year period. Therefore, your pillow
is the most obvious place to start with dust mite encasings
if you do not want to bury your nose into dust mites every
night.
My
favorite dust mite encasings are Cottonfresh
and I think they are worth the extra money. Apart from the
added benefit that they are organic and unbleached, they are
also the softest. Think about it for a moment. The softest
and most supple dust mite cover underneath your pillowcase
means that your pillow retains its soft and supple feel. Important
for those of us who like to scrunch up our pillows and mash
them underneath our heads.
I get
routinely get asked as to which is the BEST dust mite encasing
or cover. The answer is when it comes to dust mite encasings
we do not sell any brand which let the dust mites through.
Our fabrics are tightly woven and the beesties simply cannot
wiggle their way through. The best is a cosmetic or comfort
choice, and we prefer ones which are made out of cotton.
Looking
for a cheap dust mite cover? Then encase your mattress with
a plastic or garbage bag. A little facetious? Well perhaps,
but plastic does a great job, it cuts the dust mites off from
their food source which is you and your skin flakes. Trouble
is you will find it sweaty and the noise of the plastic would
drive your crazy. Some encasings are only a small step away
from a garbage bag- trust me I slept on one at my father’s
condo this last Spring. Every time I turned over that darned
crinkle sound woke me up. And I dare not take the cover off;
the pillow was at least 30 years old! I was convinced I was
sleeping on a bag of dust mites!
Do you
need a dust mite cover on your box spring? In my mind unless
you are super allergic it is going too far and you can do
without one. But as a caveat dust mites do travel and crawl
where they are not wanted. I like our middle of the road cotton
dust mite encasings for this job
How about
the mattress? It is worth having a dust mite encasing here,
but remember if you have a latex
mattress you probably do not need an encasing at all as
latex is inhospitable to dust mites.
I get
asked how often you need to wash the dust mite covers? This
is a matter of hygiene not anything to do with the effectiveness
of the dust mite covering. Washing dust mite covers does not
rejuvenate them from the dust mite prevention perspective.
Putting it bluntly, people drool into their pillows, sweat
and do other things at night which make it necessary to freshen
the bedding by washing. Dust mite covers are no exception.
How about
dust-mite covers for duvets?
In a perfect world you would have a duvet or comforter that
was anti social for the dust mite party. These comforters
are made out of silk
or wool.
Hypoallergenic down comforters can still be a breeding ground
for dust mites but the ones with a higher thread count shell
will keep the dust mites at bay. If you need a dust mite cover
for your comforter again we think Cottonfresh
wins out as it keeps the comforter supple and light which
is how you want your comforter to be.
Why bother
with a dust mite cover if your regular duvet cover is high
thread count? Good question but unless your duvet cover has
zippered tight enclosures, those adolescent dust mites will
muscle their way through any opening.Adolescent dust mites
for the uninitiated, as we found out from a man who breeds
them for researchers tend to be pushy creatures who find their
way through anything and will jump around in pursuing more
food. Need I say more?
Dust Mite
Encasings for your children’s beds? Buy them the cheapest
covers, they will never know the difference. Buy the Cottonfresh
for your own pillows.
The best
and cost effective package? Buy our regular 2 cotton pillow
encasings and mattress cover and add 2 Cottonfresh pillow
dust mite encasings for your own pillows.

FAQ
for Dust Mite Encasings and Dust Mite Removal
| Q. |
What
is the difference between dust and dust mites?
|
| A. |
Dust
is the accumulation of very fine particulates, the kind
that you can sometimes see floating around the air when
the light streams through the windows late afternoon.
It is not healthy to breathe in dirt. Dust mites are
live microscopic creatures which inhabit our bedding,
carpets and upholstery. Dust mites feed on human and
animal dander, pollen, fungi and bacteria. The food
consumption and development of the dust mites increases
with higher relative humidities (55 % to 80%) and common
indoor temperatures (75 to 80 degrees fahrenheit). Since
you spend up to 1/3 of your life in the bedroom and
need a good night's sleep, it is essential to take care
of the dust mite problem there first! To keep it simple,
dust mite covers on your bedding cut off their food
source. Encase mattresses, boxsprings, pillows and comforters
in hypoallergenic tightly woven zippered
dust mite encasings. Keep your room at a low humidity
level and eliminate any dust harboring articles in the
room.
|
| Q. |
How
do I really know that I have a problem? |
| A. |
Some
of the signs of dust mite allergies are persistently
stuffy nose and ears, repeated sneezing on awakening,
itchy watery eyes, worsening of symptoms when beds are
made, improving symptoms outside the house. To check
for the dust mite level in your rooms before you begin
a plan of elimination you can use a simple home
dust mite test kit to check how bad the problem
is. In some houses the dust mite problem may be minimal
To
check your humidity level you can purchase a low cost
digital
humidity gauge.
|
| Q. |
Will
I know the dust mite encasings are there when I am in
bed? |
| A. |
Our
dust
mite encasing offerings are comfortable, noiseless
and cool. Our fabrics have a gentle, light-weight finish
which provides an effective yet luxurious feel. We offer
two cotton choices with high thread counts which makes
the fabrics tightly woven yet have exceptional breathability
that allows air and perspiration to flow through but
not the dust mites or their feces [which is what causes
the allergenic reaction]. The fabric is not hot or sweaty
to sleep on! We have evaluated other dust mite protection
barrier products and found these to be the most comfortable,
effective protection you can buy.
|
| Q. |
How
do I use dust mite encasings? |
| A. |
Dust
mite encasings are used over your pillows, mattress,
mattress pad, box spring and comforter and underneath
your pillowcases, sheets and decorative comforter cover..
Mattress/Boxspring/Pillow
Encasings:
Good:
Pristine Cotton Plus (25 % cotton/ 75% poly blend) -
15" deep
Better:
Natural Allergen Barrier 100% cotton bedset encasings
(bleached) -12" deep
Best:
Cotton Fresh 100% cotton pillow encasings (unbleached,
undyed)
Note:
Some of our customers buy one of the encasing sets and
a set of Cottonfresh encasings as well. They put the
Cottonfresh on the most allergic person's bed and use
the Pristine or Natural Allergen barrier cotton pillow
encasings for other beds in the home.
Dust
Mite Comforter Encasings:
Good: Pristine Cotton Plus (25% cotton/75%
poly blend) comforter encasings
Better:
Natural Allergen Barrier 100% cotton comforter encasings
(bleached)
Best:
Cottonfresh Comforter, Duvet Encasings 100% Cotton-unbleached,
untreated, very soft
|
| Q. |
How
do I know what size of dust mite encasing to buy? |
| A. |
You
buy the size that matches the bed that you want to cover
(twin, queen, etc.) However, we sell the dust mite encasings
in two different depths within these sizes. We sell
the mattress covers in three depths: 9 inch (standard)
12 inch (deep - These will fit standard beds as well)
and extra deep 15 inch mattress encasing sets. See the
previous question's links to go directly to the link
that you need. We suggest that you measure your mattress
height (without sheets) from at least 3 different sides
of the mattress including any pillowtop or foam mattress
pads if you have them. Buy the encasing set that best
fits the mattress size plus topper depth.
|
| Q. |
Can
I put them on by myself? |
| A. |
We
suggest that you get someone to help you since putting
them on requires that you remove the mattress and boxspring
from the frame. Put the mattress or boxspring up on
its end and gently pull the encasing evenly over the
width of the mattress. If you try to pull too much on
one side it could tear. When you have the encasing over
the entire mattress or boxspring - zip it up and return
it to the bed. Go
to this link for further detailed instructions.
|
| Q. |
Do
I have to take dust mite encasings off when I wash my
sheets and pillowcases? |
| A. |
We
recommend that you wash your regular bed linens and
pillow encasings in hot water once a week (130°F/54.4°C).
A cooler temperature will not kill the mites. You do
not have to remove the mattress and boxspring encasings
and wash them every week. Wash only for hygienic purposes.
You can remove regular bed linens and vacuum the encasing
with a HEPA vacuum or use a vapor
steam cleaner over the surface of the mattress.
|
| Q. |
Are
these cotton based dust mite encasings washable? |
| A. |
These
dust mite encasings are completely hot water machine
washable and can be tumbled dry. Do not use chlorine
bleach on the encasings.
|
| Q. |
What
should be on my checklist to reduce dust mites in my bedroom?
|
| A. |
- Encase
your mattress, boxspring, pillows and comforter in
dust mite encasings.
- Keep
humidity below 50%, ideally between 30-40%. This suggestion
is probably the most important of all, as it prevents
dust mites from breeding.
- Keep
your closet door closed. Clothes can harbor dust mites
if the door is left open.
- Avoid
upholstered furniture in the bedroom. Use plastic,
leather or wood furniture instead.
-
Remove carpeting when possible or use a low pile carpet
or throw rugs on bare floors. Wash throw rugs frequently.
If you have carpets use a vapor steam cleaner every
8 weeks to kill off the new crop of dust mites.
- Use
hepa
vacuum cleaner attachments for dusting or microfiber
cloths instead of regular mops or cloths.
- Use
light washable curtains, valances and shades or vertical
blinds on your windows. We prefer metal blinds.
- Use
a high quality HEPA
(High Efficiency Particle Arresting) air purifier
to filter out airborne allergens including dust mites.
Find one that will do an effective job at low fan
speed so that you do not have to live with noise of
an air filter at high speed. Our favorite bedroom
air purifier is the Blueair
as it is quiet.
- Dust
and vacuum twice a week using a vacuum with a HEPA
vacuum or a central
vacuum that vents particles to the outside of
the house. This will reduce the small particle dust
in the room.
- Fry
them: Use a vapor
steam cleaner on your bedding and/or scatter rugs
to assist in killing dust mites between washes.
- Freeze
dust mites: Take advantage of the freezing weather.
Put pillows, cloth or stuffed toys, anything that
could host dust mites into plastic bags and put them
out side in the deep freeze. Yes, the frost kills
the mites.
- Change
air conditioning filters before the season starts.
-
Discourage pets from bedrooms. Dust mites feed on
pet dander as well. (We know this is a tough one but
it will make a big difference!)

Pillows
and Pillow Talk
By Mercia Tapping
- President AllergyBuyersClub.com
Pillows.
You would think that talking about pillows would be easy enough,
but when I train our staff on the subject of pillows, it is a big
yawn! Our predominately male technical staff, feel uncomfortable
with pillow talk! Only Richard likes to talk about pillows and bedding to our customers, and then he tells husbands to get their wives
on the phone to talk to him! Pillows, it would seem are perceived
as something for women only. Yet try telling that to my husband
who has worked his way systematically through more pillows than
I care to name on his way to the perfect one!
We have tried
pillows made out of hypoallergenic down, Primaloft, wool, alpaca,
latex and cotton. We have tried them out in firm, medium and soft.
But here is the bottom line about pillows. Your pillow choice is
a very personal one. All we try to do is give you sufficient selection
among the many that we have reviewed and tried out.
What we have
done is weeded out in our testing of pillows that have odors to
them, attract mold, or in some way are poor manufacturing quality.
We also have culled through dozens of pillows to find those, which
we think, are the most friendly to allergy sufferers.
So in the spirit
of keeping it simple, here is what I tell our customers about pillows.
1. If you like
a soft pillow there is no substitute for down, and most people prefer
a soft to medium down pillow. Hypodown is expensive but it lasts
a great deal longer than the cheaper grade down pillows. The Syriaca
in Hypodown
pillows, which binds to the down plumes, actually helps the
longevity of the pillow as well as making it “allergy free”.
2. Many people
have allergies to down pillows, which has mainly to do with dirt
left on the feather quills. If the down is put through a number
of extra washes, this removes the dirt and hence the allergens for
the vast majority of people. A Hypodown pillow receives the highest
industry grade [turbidity] for cleanliness and with the Syriaca
it gets an extra boost to be hypoallergenic.
3. If you want
to be on the safe side and the price of Hypodown is too high, then
Primaloft
pillows come close to giving the feeling of down at a reasonable
price. My only caveat is Primaloft pillows do not last long. We
seem to replace our Primaloft pillows almost on an annual basis,
but they are wonderful if you want to scrunch something underneath
your head.
4. Pillow “scrunchers”
should always buy a “soft” pillow.
5. All the other
pillow fill choices are a lot firmer, but for someone with severe
allergies or multiple chemical sensitivities they are a healthy
choice.
6. Wool
or cotton
pillows are both naturally hypoallergenic and very healthy fibers
as they allow for natural wicking away from the body and are “breathing”
fibers. Both wool and cotton pillows are naturally inhospitable
to dust mites as they dry out very quickly from moisture created
by our bodies.
7. Cotton
pillows are softer than most wool
pillows but are best for people who prefer a pretty flat pillow
as they compress fairly quickly. For people with multiple chemical
sensitivities this is the pillow of choice.
8. It is a rare
person who is allergic to wool and wool pillows are covered with
a tightly woven ticking. A wool pillow will serve you faithfully
for years. If given a choice in pillow fill, I would recommend the
softest available since I have come across some which to me seem
rock hard. Alpaca,
when it is mixed with wool, provides a softer
wool pillow and our Euphoria line of pillows is just as soft
as its matching comforter. These wool pillows are far softer than
the average wool pillow.
9. Latex
pillows are the firmest of all and are often contoured for neck
support. They remain in perfect shape for years but the pillow-scrunching
brigade would hate them. Natural latex is inhospitable to dust
mites and mold.

Files Complaint With FTC Against Consumer Reports Magazine
Monday September
29th 2003
Watchdog
Agency May Be Doing Consumers More Harm Than Good
SANTA
FE SPRINGS, Calif., Sept. 29 /PRNewswire/
--
IQAir North America announced today that it has filed a complaint
with the Federal Trade Commission (FTC) against Consumer Reports
Magazine and its parent company, Consumer Union, charging
that the consumer watchdog organization actually harms consumers
and businesses with inadequate investigative techniques and
a biased selection process that ignores quality manufacturers
in place of mass market distributors.
IQAir
is the top rated room air cleaner according to Test (Stiftung
Warentest), the prestigious German government funded testing
agency, but since IQAir's inception they have been unable
to get their product reviewed by the popular Consumer Reports
organization. This month the October issue of Consumer Reports
Magazine hit the newsstands with a much publicized article
that blasted the Sharper Image's top selling Ionic Breeze
as "poor" in most categories and bestowed top honors
on Friedrich's electrostatic precipitator, a unit known to
produce charged particles and that may produce the lung irritant
ozone. IQAir was again not able to get their home HealthPro
series tested for the article even though many consumer advocacy
groups and specialty retailers consider them the best product
in the category, including Consumer Review, AllergyBuyersClub.com,
Air-Purifiers-America.com and many other groups that support
allergy and asthma sufferers. The Hong Kong Hospital Authority
this month tested IQAir as the only room air cleaner effective
enough to be used in the fight against SARS.
Consumer
Reports Magazine has often been accused of using market share
to choose its test products. Specialty retailers who frequently
deal with a higher quality of merchandise than mass retailers
have long decried this practice since major brands like Honeywell,
Hunter, and Friedrich are included, but smaller manufacturers
who strive for a higher manufacturing standard are excluded
simply because they don't sell as many units.
"Consumer
Reports does a disservice to consumers," states IQAir
President Frank Hammes. "Three and a half million room
air cleaners were sold in America last year. Over the past
two years, the nation has seen air cleaners move from a pure
allergy and asthma control product to a tool that also helps
victims of terrorist attacks cope with the aftermath of airborne
pollution. They've become an integral part of the nation's
homeland defense strategy. This is not a time for Consumer
Reports to use outdated selection methods. They are keeping
the best products from being tested."
At the
heart of IQAir's complaint against Consumer Reports is not
just their selection process, but also how the air purifier
units are being tested. Consumer Reports adopted a testing
procedure developed and promoted by the Association of Home
Appliance Manufacturers (AHAM) for most of their air cleaner
evaluation.
"AHAM
is in their own words an advocacy group for manufacturers,"
explains Hammes. "They represent big industry interest
and not that of consumers."
AHAM promotes
a marketing program in which they certify the performance
of room air cleaners of their members. According to insider
information, the Consumer Reports tests were carried out by
the same contract test laboratory that carries out all AHAM
certification testing. The Consumer Reports test, like the
AHAM test, is considered flawed by many industry experts,
and most quality air purifier manufacturers do not sign up
for AHAM certification because of the test flaws.
"Consumer
Reports uses a biased selection process to choose which products
to test," said Hammes. "Then when it does test the
units it uses the AHAM test procedure which was designed by
big business manufacturers to support the often inferior products
they were trying to sell. The Consumer Reports test results
confuse consumers rather than provide them with clear and
accurate information. Parents with children who suffer from
allergies and asthma will be guided to buy inferior quality
room air cleaners because they put their trust in Consumer
Reports."
IQAir
North America, Inc. is a member of the Swiss-based IQAir Group
that develops, manufactures and markets innovative air quality
products for indoor environments. IQAir products are used
worldwide by hospitals and other critical environments. They
also manufacture home air cleaning units for allergy and asthma
sufferers and individuals with chemical sensitivities.

Email About The Blueair Air Purifier
For
many years I have been unable to get a proper night's sleep
during the hay fever season. Every night I would spend hours
sneezing, with my eyes running constantly. To be honest I
had become resolved to the fact that this was just part of
life. However, a friend recommended the Blueair air purifier,
and I gave it a try. I have to say that it made a huge difference.
At night I was hardly aware of the hay fever season at all,
and can't remember being troubled by it at all at night; while
during the day away from the air filter, it was back to normal!
I would really recommend this air filter. It not only does
the job, but it is also very very quiet, so it happily runs
all the time with very little noise. It certainly helped me.

Rhinitis Medicamentosum by Murray Grossan MD
Rhinitis
Medicamentosum (RM) is a fancy name for being addicted to nose drops.
What happens
is that your nose is stuffy and you can’t sleep. So you spray
with the nose spray and open the nose beautifully. Now you can breathe
and sleep.
But later, the
nose clogs again and you use the drops again, maybe more that the
first time. At first you only use them every 12 hours. Then every
8, then 6. Now every four. You KNOW the bottle says only use for
a few days, but the nose is really plugged unless you use the drops.
Meanwhile you feel nervous and irritable. This is the “adrenergic”
effect of the drops, whether you take them orally or by nasal spray.
These are the
common nasal sprays that can cause RM.
Oxymetazoline
(Afrin)
Phenyleherine (Neosynephrine)
Xylometazoline (Otrivin or Inspire)
Any constrictor
nose drop can do this. There is evidence that it is the preservative,
usually benzalkonium (BZK) that is the culprit. So that the afrin
– oxymetrazoline - shrinks the nasal tissue but the BZK irritates
it so that you need more afrin. These products without BZK may not
cause RM.
Strangely, in
my practice, it is the medical people that have the high incidence
of RM. Probably it is because these medications are so readily available.
It is easy to
tell the patient to stop using the product, but the extreme misery
is quite severe and often will power doesn’t work, even in
the most strong willed persons.
One solution
is a course of prednisone with antibiotic. This will shrink the
nose and reduce inflammation. Sometimes I add Benadryl at night
to help the patients get his sleep. This is a fairly severe course
of therapy.
Another gentler
solution is to gradually dilute the drops you are using. You can
get a program of gradual reduction of the nasal drops through a
company called Rhinostat Systems. Here they make a solution for
you so that you gradually reduce the dose. Since you are no longer
getting the rebound effect, this is a preferred method, and you
avoid “more drugs”.
In some cases
where the medication has been used a long time, the cilia fail
to resume good movement right away and the nose may still feel
as though it is stuffy. Hot tea, chicken soup, compresses to
the sinus area all may help. Or pulsatile irrigation with Hydro-Pulse® Nasal
Sinus irrigator is a rapid way to refresh the
nose. The Hydro Pulse nasal / sinus irrigator pulses at a rate
to best restore normal cilia speed. This is important because
the condition that caused the patient to overuse nose drops
may still be present and it is best to get the cilia back moving
properly.
Prevention?
Persons today are constantly exposed to advertisements: take this
pill and use this spray. If you do get a stuffy nose, on the first
day, take it easy. Don’t rush to the medicine cabinet. Plenty
of tea and rest may be all you need. But once you start overusing
the nasal sprays, you can wind up addicted. Not because you are
“weak”, but because of the rebound effect of these medications.
I must emphasize
that “willpower” is not the issue here. RM is no different
than one person getting a large bump from an insect bite. The RM
is a “chemical” condition caused by the rebound of the
medication. Patients with RM do need assistance to quit the nose
spray habit. Best of course is not to get started.
Cortisone sprays,
saline sprays without benzalkonium, Breathe.ease XL spray –
these do not cause Rhinitis Medicamentosum. Some persons find they
need to continue using certain cortisone sprays, but that is not
the rebound phenomenon but rather that they are helped by it.
If only getting
cured of my addiction to chocolate candy were this easy!

Nasal Irrigator for sinus sufferers is available at AllergyBuyersClub.com

After
The Storm - Now What?
Flood Remediation
from the
Staff at Aerias.org
During
a flood cleanup, the indoor air quality in homes, offices
or any type of building may at first glance be the last thing
on anyone's mind, but failure to completely and properly dry
building interiors and remove any and all contaminated materials
can result in serious long-term health risks to building occupants.
Standing
water and wet materials are a breeding ground for microorganisms,
including bacteria and mold. They can trigger allergic reactions
or make asthma symptoms worse, and continue to damage building
materials, furnishings long after the flood.
Safety
First
Safety
is the first concern when entering a home or building that
has been damaged by floodwaters. Here are some guidelines:
* Check
for structural damage. Do not go in if there is any chance
of the building collapsing.
* Upon
entering the building, do not use matches, cigarette lighters
or any other open flames, since natural gas and other combustible
fumes may be trapped inside. Instead, use a flashlight.
* Be
careful walking around. After a flood, steps and floors are
often slippery with mud and covered with debris, including
nails and broken glass.
* Keep
the electrical power off until an electrician has inspected
the electrical system for safety.
* Until
local authorities proclaim the water supply to be safe, boil
water for drinking and food preparation vigorously for five
minutes before using.
Next
Priority -- Drying Out
Once the
building has been judged structurally sound, the next priority
is to dry it out!
Many microorganisms,
including mold begin growing within 24 to 48 hours. As a result,
it is imperative to begin the drying process as soon as possible.
Here are some steps to follow:
1. Remove
standing water
2. Identify and remove animal carcasses and
materials affected by the water
3. Dry out the area
4. Wear protective clothing
5. Clean and disinfect
6. Hire professional help
Remove
Any Standing Water
Standing
water is a breeding ground for microorganisms, which can become
airborne and be inhaled. In addition, floodwater that contains
sewage or decaying animal carcasses may also harbor infectious
microorganisms. To minimize health problems and lessen structural
damage, all standing water should be removed as quickly as
possible.
Identify and Remove Animal Carcasses and Materials Affected
by the Water
If a flood
involves sewage-contaminated water or has animal carcasses
floating in it, do not try to save any of the materials as
exposure to this kind of water carries the additional hazard
of infection with the hepatitis A virus.
Bag and
throw away any materials that can trap mold. Also, make sure
that there is no asbestos or lead in the materials to be thrown
out. Disturbing or removing materials containing asbestos
(such as in insulation) or lead (such as in lead-based paint)
may result in elevated concentrations of those hazardous materials
in the air. Just looking will not yield a definitive answer.
Sampling may need to be done to verify the materials' composition.
Some materials
tend to absorb and keep water more than others. If these materials
get wet and cannot be thoroughly cleaned and dried, discard
them. Otherwise, they can remain a source of future microbial
growth. Mold may begin growing 24 hours after the materials
become wet although there may not be any visible signs of
it. Molds are mistakenly considered more of a nuisance than
a health threat, but their damage can be long lasting. Examples
of water-absorbing materials that must be removed and thrown
out include:
- Ceiling
tiles
-
Insulation
-
Paper
-
Rags
-
Drywall
-
Mattresses
-
Wicker furniture
-
Straw baskets
|
- Upholstered
furniture
-
Old boxes
-
Stuffed toys
-
Drapes
-
Plaster
-
Cork bulletin boards
-
Old clothing
-
Books
|
These
items can retain water and begin growing mold even if they
appear to be dry. Some may become contaminated with mold while
wet and continue to be a source of mold spores and exposure
even after drying. Flooded carpet, for example, can store
mold spores for years. Any carpet if not properly maintained
can store mold spores, and flooded carpet allows the mold
to grow further. Running fans and opening windows is not enough.
Once carpet becomes colonized (mold growing in the material),
it needs to be discarded unless professional cleaning can
effectively remove the microbiological contaminants.
Remove
all drywall and insulation damaged by water at least 12 inches
above the high water mark. Visually inspect the wall interior
and remove any other materials with visible mold growth. (This
step may have to be carried out by a licensed contractor.)
This removal of mold-contaminated material from the walls
is crucial because both allergic and toxic effects can remain
in dead spores.
Dry
Out the Area
If areas
are wet, yet have not suffered from a flood, set up fans and
turn on the HVAC system to help dry things out. It is important
to do this because microorganisms like mold can quickly begin
growing in materials. These can later be released into the
air and trigger allergies and asthma attacks along with other
health problems. If humidity levels are increased for a long
time then dust mites may grow. Dust mites prefer humidity
levels above 60 percent.
Be patient!
The proper drying out process can take a long time.
In large
buildings, the typical drying out period may be 7 to 10 days.
It is imperative to not only dry the building, but to dry
it out correctly. Drying out large buildings is a very complex
process and will require the help of professionals. Believe
it or not, if a building is dried out too quickly, interior
furnishing materials can become damaged.
If the
structure does not have electricity, do not use internal combustion
engines indoors since they can quickly emit deadly levels
of carbon monoxide. Examples include gasoline-powered generators,
camp stoves and lanterns, or charcoal-burning devices. Do
not use combustion devices designed for outdoor use inside,
even in an emergency, since that can be deadly!
Dress
the Part
Because
mold may have begun growing in some of the materials that
will be removed, be sure to wear appropriate protective clothing.
Cleaning up mold can be hazardous to health since mold counts
are typically 10 to 1,000 times higher than background levels
during the cleaning of mold damaged materials. Here are some
steps to follow:
* Wear
a dust mask or particulate respirator (sometimes referred
to as a N95 or TC-21C particulate respirator) to keep from
breathing in airborne spores. However, remember this type
of mask will not protect the persion wearing it from the vapors
of cleaning or bleach solutions that can irritate eyes, nose,
and throat, and damage clothing and shoes. In addition to
protective equipment, make sure the working area is ventilated
well.
* Wear
eye-protection
* Wear
gloves. While removing materials, cover rubber gloves that
may tear easily with work gloves. Be sure to wear gloves when
using cleaning and disinfecting solutions.
* Wear
sturdy waterproof boots to protect the feet from hazards,
which may not visible in dirty floodwater.
* Wear
protective clothing that is easily cleaned or discarded
Clean and Disinfect 
All surfaces
that are exposed to food, children or pets will need to be
thoroughly cleaned. Also clean and disinfect non-porous materials
such as glass, plastic or metal. Materials such as the tops
of metal desks or file cabinets and concrete, cement, or tile
floors can be cleaned using a solution
of one (1) part bleach to 10 parts water. Be sure the area
is well ventilated.
* Ask
staff or bystanders to leave when these areas are being cleaned.
* Before
beginning to clean off any mold, try cleaning a small test
patch of it first. If you feel that this adversely affected
your health, you should consider paying a licensed contractor
or professional to carry out the work.
* Use
soap/detergent and hot water or a commercial cleaner. DO NOT
APPLY ANY AMMONIA-BASED PRODUCTS! Ammonia or ammonia-based
cleaners should not be used since residual ammonia can encourage
mold growth.
* Thoroughly
scrub all contaminated surfaces (use a stiff brush to clean
block walls) with an excessive amount of soap/detergent.
* Rinse
well with water
* After
thorough cleaning and rinsing, disinfect the area. To disinfect,
use a solution of 10 percent household bleach (for example,
one (1) cup bleach per five (5) gallons of water) and a little
detergent. (The detergent will help with the dirt and oil
on the surface and act as a surfactant to help thoroughly
wet all surfaces). NEVER MIX BLEACH AND AMMONIA SINCE THEY
CAN FORM DEADLY VAPORS!
* Bleach
solution should be applied with a handheld garden sprayer.
For large exterior areas, you can spray using a garden hose
and nozzle but avoid excessive amount of runoff or standing
bleach.
* When
disinfecting a large structure, make sure the entire surface
is wetted (floors, joists and posts). Use a brush or broom
to force the solution into crevices.
* Be
sure you wash and disinfect the walls, floors, closets, shelves,
and contents. The HVAC system should be evaluated for mold
contamination and professional help engaged to handle the
evaluation and cleaning of the system.
* Work
over short time spans and rest in a fresh air location. Provide
continuous and controlled ventilation in work area, with the
area of contamination kept at a negative pressure in relationship
with the rest of the home. Iin other words, air should flow
from clean to dirty areas.
* Allow
bleach solution to dry naturally for a six to eight hours.
* Air
out the house (and the building if windows can be opened)
out for about two to three days after the work. Increase airflow
in the house by moving furniture away from walls and opening
closet doors. Consider increasing outdoor airflow in buildings
in which windows cannot be opened.
Hire
Professional Help
Most mold
remediation guidelines advise that if the area of mold growth
is larger than 10 sq. ft. to hire a professional contractor
to remove the mold and any contaminated materials. But be
careful! After a major storm, unqualified opportunists may
offer to help. Be wary of people who drive through neighborhoods
offering help in cleaning up or repairs. Be sure that any
contractors that are hired for cleanup or repairs are qualified
to do the job. Check their credentials and their references.
Insurance adjusters may be able to assist in finding reputable
and qualified contractors.
