Dear Everyone

I have to tell you something very strange about our company which defies statistical probability- a full 20% of the people here at AllergyBuyersClub.com share the same birthday, March 19th, and we unknowingly hired another one a couple of weeks ago - now is that weird or what? My birthday is NOT March 19th but I can tell you this group have quite the birthday bash each year. The only thing I have observed about all these people is they are all good team players. So someone please tell me the odds of this happening!
 

 

Bob Cobe, our product specialist, has been on my case for a while to improve the comparison charts and guides for various products we carry. Out of desperation, he has been doing them himself for the benefit of training our internal staff, and the results of his labors can be seen in our next newsletter, which will have a particular focus on humidifiers.

Do not miss the press release below sent out by IQAir who have filed a complaint against Consumer Reports - gutsy move.
 

Enjoy the Fall, even if I am sneezing again!

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.

CottonFresh Dust Mite EncasingsDust 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.
  1. Encase your mattress, boxspring, pillows and comforter in dust mite encasings.
  2. Keep humidity below 50%, ideally between 30-40%. This suggestion is probably the most important of all, as it prevents dust mites from breeding.
  3. Keep your closet door closed. Clothes can harbor dust mites if the door is left open.
  4. Avoid upholstered furniture in the bedroom. Use plastic, leather or wood furniture instead.
  5. 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.
  6. Use hepa vacuum cleaner attachments for dusting or microfiber cloths instead of regular mops or cloths.
  7. Use light washable curtains, valances and shades or vertical blinds on your windows. We prefer metal blinds.
  8. 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.
  9. 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.
  10. Fry them: Use a vapor steam cleaner on your bedding and/or scatter rugs to assist in killing dust mites between washes.
  11. 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.
  12. Change air conditioning filters before the season starts.
  13. 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.

IQAir 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.

Customer 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!

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.
