SAFE
ROOMS AND OVER PRESSURIZATION.
SAFE ROOM OR SAFE HAVEN
By Mercia
Tapping
The concept
of a "Safe Room" or "Safe Haven" in the
home is one well known to Allergy, Asthma and Multiple Chemical
Sufferers. A safe room is one, which the goal is to rid the
air of any biological contaminants such as mold, cat allergens
and pollen, viruses, bacteria and environmental pollution
and gases. Traditionally, this room has been the bedroom,
being the room where most people spend more hours in their
home than anywhere else. In fact, the same principles can
be applied to any room of the house, which the homeowner wishes
to designate as being toxin free.
We have
discussed some of these issues before, in terms of general
hygiene, in articles Living
with Cats, The
Dust Free Bedroom, and when the anthrax scare was at its
height 18 months ago we published a responsible article by
Frank Hammes, IQAir
Filters and Airborne Biological Warfare - Do Air Filters Help?
And for those looking for relief from odors and gaseous contaminants
our FAQ on Filtration
of Gaseous Pollutants and Odors.
The problem
that all safe rooms face, is how to bring sufficient uncontaminated
fresh air into a room, so that people will have sufficient
oxygen. While the idea of hermetically sealing a room sounds
initially attractive, you could also be creating a tomb where
the air will run out and you will suffocate.
The answer
lies in positively pressurizing a room, a concept that takes
some explaining. In order, to provide occupants with a completely
toxin-free room with pure air, air needs to be drawn into
the room from the outside (exterior or nearby room) through
exceptionally high grade HEPA and carbon filters, so only
pure air reaches the interior of the room. This method is
much more effective than having a standalone HEPA air purifier
filter the air already in a room.
This is
where the efficiency of the filters becomes critical. No longer
can you be content to let contaminated air circulate through
the filters several times before being trapped in HEPA and
carbon filters. Most air purifiers we have found are lacking,
with efficiency ratings in our own testing, ranging from 35%
to 85%. Only with the hyper HEPA filters of something like
IQAir, can you be reassured that almost nothing gets
past its filtration system on the first pass.
If
you use the positive pressure optional kit for your IQAir
filter, you can bring the fresh air in safely from the outside
through a duct fitted into your window or wall (exterior or
inside wall). If you are bringing in new air from the outside
then you have a surplus of air for the volume of air that
can fit into that room. What happens next? The surplus air
escapes out of the room through all the nooks and crannies,
which are quite normal in non air-tight houses.
Positive
pressurization can be used in the following circumstances:
1. Ridding
a room of airborne allergens such as pollen, dust mites, mold
and cat allergens. Allergens can be inside based or even outside
sourced.
2. Expelling
any virus or bacteria from the room and forcing them out through
cracks in the house to the outside air.
3. Intaking
clean smog-free, fume-free, allergen-free, virus- and bacteria-free
air, into a room when the outside air is polluted for some
reason.
4. Providing
a home based "clean room" for someone who has multiple
chemical sensitivities or needs a toxic-free hospice environment.
5. Clearing
a virus-laden environment such as nursery schools where many
children have colds, or a pet shelter where there are airborne
viruses, which are spreading within the shelter.
6. Getting
clean allergen-free fresh air into the home during pollen
or mold season.
Retrofitting
your existing IQAir machine for positive pressurization
or buying a complete kit from scratch is expensive, so the
cost and potential benefits need to be carefully considered.
Most people most of the time can tolerate some toxicity; the
time to use over pressurization is when you are dealing with
people with compromised immune systems such as the young,
elderly or sick or when the level of toxic pollution for any
reason has reached such a level as to be considered dangerous
to the population at large.

CLEANING
UP ELDERLY ODORS
By Mercia Tapping
As anyone
who has elderly parents knows, there may come a time when one
gently has to tell them that their house does not smell so good.
The deteriorating sense of smell with the elderly and the effort
required to implement maintain a hygiene routine, all contribute
to the problem. On the whole men seem to do less well than women,
but in my own family, the source of the problems has been gender
wide.
Before
a recent trip to London, my sister warned me that staying
in my Dad's condo was going to require me to hold my nose.
My sister
was pretty accurate in her predictions when I walked into
my Dad's place, but by the end of my stay she was amazed that
both my Dad and his condo smelled perfectly normal.
Much
of what I did was common sense, low cost or free. Other clean-up
strategies involved a Ladybug
steam cleaner and a Blueair
air purifier with smoke stop filters.
Here is
a quick summary of what I did. I hope it might give some of
you some ideas. The whole purpose behind what I did was to
attack the source not just try and cure the symptoms.
1. First
and most obvious, open the windows for at least half an hour
per day. I opened them for several hours at the beginning
of my stay.
2. I took
sackfuls of soiled clothing along to the dry cleaners and
washed all bathroom mats and sheets and bedding. On my next
trip, I will take some home kit dry cleaning kits "DRYEL"
which I can get at my local pharmacy - they work in the drier
- not too well, but a cheap way of keeping my Dad's clothes
clean on an ongoing basis.
3. I installed
a shower caddy in the shower stall complete with shower gel
and shampoo, and fixed the water mixer so my Dad would not
scald himself. We instituted a reward program for taking a
shower on Sundays as my sister said she would take him to
church and Sunday brunch every week, provided he took a shower.
4. We
put deodorizers in the toilets.
5. I threw
away all the mothballs, and replaced them with herbal moth
repellent sachets.
6. I introduced
him to joys of clumping cat litter with a quick scooper for
daily upkeep of cat deposits.
7. I brought
over some spray deodorizer called Oxyfresh from the US, which
I have used for years. I like it because it works and it is
fragrance free. You can get some via their web site.
8. Since
his vacuum cleaner had been broken for six months, it clearly
was on the "replace immediately" list. If he had
been in the USA I would have bought him a Sebo
X1 upright as the whole of his condo is carpeted.
9. I used
the Ladybug
steam cleaner with great ease and amazing speed on bathroom
odors which clung to floor tiles, and I used the steel brush
to clean dirty tile grout [tiles are always porous], kitchen
floor tiles. A small amount of Formula 212 Spot Cleaner for
places on the carpets where there had been "accidents",
followed by steam cleaning did the trick. I then steamed all
the remaining clothing in the closet, so everything got a
fresh smell. I steam cleaned the lambs
wool mattress pad I had given my Dad of Christmas a year
ago, which was stained in one area. All in all, the Ladybug
steam cleaner did incredible Trojan work and left everything
it touched with a sweet fresh smell.
10. Finally,
we installed a Blueair
air purifier with smoke stop filters to take the final
edge off things. I like this air purifier for the elderly
as it is very quiet, and the filters take all of 10 seconds
to change and with no effort or heavy lifting.
The result?
I am happy and relieved to say that both my father and his
condo smelled just fine by the time I left. Do I need to go
and make a check up visit to see how things are going? For
sure - Rome was not built in a day but at least I put things
back on track for a while.

BEDS
AND BEDDING - HEAVEN OR HELL
by Mercia Tapping
On my first
night in London recently my 6' 3" husband and I squished ourselves
into a 4ft-wide bed, whose 30-year-old mattress sagged if you so
even as much as breathed on it. "Do not move a muscle",
I admonished my husband, as any movement from him caused the mattress
to undulate like an earthquake eruption. My husband asked, "What
is all that crackling noise on the pillows?" I informed him
that cheap pillow protectors or dust mite encasings were often plasticized
and felt like Pampers or an incontinence pad underneath one's head.
At 3 am, I crabbily informed him that the comforter was clearly
a single, not a double, but he was going to have to share because
I was freezing. By morning time, we both admitted defeat. My husband
who had foolishly boasted to my Dad that he could sleep on anything,
was about to eat his words. "It is a new bed or a hotel",
he said firmly.
A loan of a
comforter from my sister and the purchase of a new bed the same
afternoon allowed us some semblance of sleep for the next 9 days.
However, I confess that I looked at the bedding on my father's bed
and our own with something akin to distain, disgust and incredulity
all week long.
"This is
a dead pillow," I said to my husband, "the deadest you
will ever see". The feathers were coagulated into one hard
flat lump. If you fold a pillow in half and it stays in place, this
is a sure sign of rigor mortis. The average pillow lasts 18 months.
These pillows were somewhere between 30 and 40 years old and the
odor was none too grand either.
As
for the bed as new as it was, you get what you paid for, and my
bones ached all week. I got out of bed feeling and walking like
a cripple. However, I have you know, I kept my complaints to myself
and soldiered on with good British stiff upper lip.
When I returned
to Boston, I wearily crawled into bed-and then I confess, I was
completely taken aback and surprised. The contrast was so great,
there are hardly words to describe it, and I just lay there savoring
the experience and counting my blessings. Our Primaloft
soft and Hypodown
soft pillows felt like clouds under my head and my Monarch
Hypodown comforter (Arctic strength) just enveloped me in reassuring
toasty, but lightweight warmth. Thank God, warm at last. I could
feel the softness of the lambswool
mattress pad underneath. As for the bed itself, a Royal
Pedic, was true miracle of latex support and cushion at the
same time. But the real proof was, I had a really decent night's
sleep, woke up refreshed and with no backache or joint pain.
I thought sadly
of my poor Father the other side of the Atlantic who grumbles about
how uncomfortable his bed is, and I made a promise to myself that
on my next trip he will get a major
bedding upgrade.

BIOLOGICAL
POLLUTANTS IN YOUR HOME
Prepared
by:
The Consumer Product Safety Commission (CPSC), and The American
Lung Association, The Christmas Seal People
This guidance
will help you understand:
1. what
indoor biological pollution is;
2. whether your home or lifestyle promotes its development;
and,
3. how to control its growth and buildup.
Outdoor
air pollution in cities is a major health problem. Much effort
and money continues to be spent cleaning up pollution in the
outdoor air. But air pollution can be a problem where you
least expect it, in the place you may have thought was safest--your
home. Many ordinary activities such as cooking, heating, cooling,
cleaning, and redecorating can cause the release and spread
of indoor pollutants at home. Studies have shown that the
air in our homes can be even more polluted than outdoor air.
Many Americans
spend up to 90 percent of their time indoors, often at home.
Therefore, breathing clean indoor air can have an important
impact on health. People who are inside a great deal may be
at greater risk of developing health problems, or having problems
made worse by indoor air pollutants. These people include
infants, young children, the elderly, and those with chronic
illnesses.
What
Are Biological Pollutants?
Biological
pollutants are or were living organisms. They promote poor
indoor air quality and may be a major cause of days lost from
work or school, and of doctor and hospital visits. Some can
even damage surfaces inside and outside your house. Biological
pollutants can travel through the air and are often invisible.
Some
common indoor biological pollutants are:
- Animal
Dander (minute scales from hair, feathers, or skin)
- Dust
Mite and Cockroach parts
- Fungi
(Molds)
- Infectious
agents (bacteria or viruses)
- Pollen
Some of
these substances are in every home. It is impossible to get
rid of them all. Even a spotless home may permit the growth
of biological pollutants. Two conditions are essential to
support biological growth: nutrients and moisture. These conditions
can be found in many locations, such as bathrooms, damp or
flooded basements, wet appliances (such as humidifiers or
air conditioners), and even some carpets and furniture.
Modern
materials and construction techniques may reduce the amount
of outside air brought into buildings which may result in
high moisture levels inside. Using humidifiers, unvented heaters,
and air conditioners in our homes has increased the chances
of moisture forming on interior surfaces. This encourages
the growth of certain biological pollutants.
The
Scope Of The Problem
Most information
about sources and health effects of biological pollutants
is based on studies of large office buildings and two surveys
of homes in northern U.S. and Canada. These surveys show that
30% to 50% of all structures have damp conditions which may
encourage the growth and buildup of biological pollutants.
This percentage is likely to be higher in warm, moist climates.
Some diseases
or illnesses have been linked with biological pollutants in
the indoor environment. However, many of them also have causes
unrelated to the indoor environment. Therefore, we do not
know how many health problems relate only to poor indoor air.
Health
Effects Of Biological Pollutants
All of
us are exposed to biological pollutants. However, the effects
on our health depend upon the type and amount of biological
pollution and the individual person. Some people do not experience
health reactions from certain biological pollutants, while
others may experience one or more of the following reactions:
- Allergic
- Infectious
- Toxic
Except
for the spread of infections indoors, ALLERGIC REACTIONS may
be the most common health problem with indoor air quality
in homes. They are often connected with animal dander (mostly
from cats and dogs), with house dust mites (microscopic animals
living in household dust), and with pollen. Allergic reactions
can range from mildly uncomfortable to life-threatening, as
in a severe asthma attack. Some common signs and symptoms
are:
- Watery
eyes
- Runny
nose and sneezing
- Nasal
congestion
- Itching
- Coughing
- Wheezing
and difficulty breathing
- Headache
- Fatigue
Health
experts are especially concerned about people with asthma.
These people have very sensitive airways that can react to
various irritants, making breathing difficult. The number
of people who have asthma has greatly increased in recent
years. The number of people with asthma has gone up by 59
percent since 1970, to a total of 9.6 million people. Asthma
in children under 15 years of age has increased 41 percent
in the same period, to a total of 2.6 million children. The
number of deaths from asthma is up by 68 percent since 1979,
to a total of almost 4,400 deaths per year.
INFECTIOUS
DISEASES caused by bacteria and viruses, such as flu, measles,
chicken pox, and tuberculosis, may be spread indoors. Most
infectious diseases pass from person to person through physical
contact. Crowded conditions with poor air circulation can
promote this spread. Some bacteria and viruses thrive in buildings
and circulate through indoor ventilation systems. For example,
the bacterium causing Legionnaire's disease, a serious and
sometimes lethal infection, and Pontiac Fever, a flu-like
illness, have circulated in some large buildings.
Talking
To Your Doctor
Are you
concerned about the effects on your health that may be related
to biological pollutants in your home? Before you discuss
your concerns with your doctor, you should know the answers
to the following questions. This information can help the
doctor determine whether your health problems may be related
to biological pollution.
- Does
anyone in the family have frequent headaches, fevers, itchy
watery eyes, a stuffy nose, dry throat, or a cough? Does
anyone complain of feeling tired or dizzy all the time?
Is anyone wheezing or having difficulties breathing on a
regular basis?
- Did
these symptoms appear after you moved to a new or different
home?
- Do
the symptoms disappear when you go to school or the office
or go away on a trip, and return when you come back?
- Have
you recently remodeled your home or done any energy conservation
work, such as installing insulation, storm windows, or weather
stripping? Did your symptoms occur during or after these
activities?
- Does
your home feel humid? Can you see moisture on the windows
or on other surfaces, such as walls and ceilings?
- What
is the usual temperature in your home? Is it very hot or
cold?
- Have
you recently had water damage?
- Is
your basement wet or damp?
- Is
there any obvious mold or mildew?
- Does
any part of your home have a musty or moldy odor?
- Is
the air stale?
- Do
you have pets?
- Do
your house plants show signs of mold?
- Do
you have air conditioners or humidifiers that have not been
properly cleaned?
- Does
your home have cockroaches or rodents?
TOXIC
REACTIONS are the least studied and understood health problem
caused by some biological air pollutants in the home. Toxins
can damage a variety of organs and tissues in the body, including
the liver, the central nervous system, the digestive tract,
and the immune system.
Coping
With the Problem
Checking
Your Home
There
is no simple and cheap way to sample the air in your home
to determine the level of all biological pollutants. Experts
suggest that sampling for biological pollutants is not a useful
problem-solving tool. Even if you had your home tested, it
is almost impossible to know which biological pollutant(s)
cause various symptoms or health problems. The amount of most
biological substances required to cause disease is unknown
and varies from one person to the next.
Does this
make the problem sound hopeless? On the contrary, you can
take several simple, practical actions to help remove sources
of biological pollutants, to help get rid of pollutants, and
to prevent their return.
Self-Inspection:
A Walk Through Your Home
Begin
by touring your household. Follow your nose, and use your
eyes. Two major factors help create conditions for biological
pollutants to grow: nutrients and constant moisture with poor
air circulation.
- Dust
and construction materials, such as wood, wallboard, and
insulation, contain nutrients that allow biological pollutants
to grow. Firewood also is a source of moisture, fungi, and
bugs.
- Appliances
such as humidifiers, kerosene and gas heaters, and gas stoves
add moisture to the air.
A musty
odor, moisture on hard surfaces, or even water stains, may
be caused by:
- Air-conditioning
units
- Basements,
attics, and crawlspaces
- Bathrooms
- Carpets
- Heating
and air-conditioning ducts
- Humidifiers
and dehumidifiers
- Refrigerator
drip pans
What
You Can Do About Biological Pollutants
Before
you give away the family pet or move, there are less drastic
steps that can be taken to reduce potential problems. Properly
cleaning and maintaining your home can help reduce the problem
and may avoid interrupting your normal routine. People who
have health problems such as asthma, or are allergic, may
need to do this and more. Discuss this with your doctor.
Moisture
Control
Water
in your home can come from many sources. Water can enter your
home by leaking or by seeping through basement floors. Showers
or even cooking can add moisture to the air in your home.
The amount of moisture that the air in your home can hold
depends on the temperature of the air. As the temperature
goes down, the air is able to hold less moisture. This is
why, in cold weather, moisture condenses on cold surfaces
(for example, drops of water form on the inside of a window).
This moisture can encourage biological pollutants to grow.
There
are many ways to control moisture in your home:
- Fix
leaks and seepage. If water is entering the house from the
outside, your options range from simple landscaping to extensive
excavation and waterproofing. (The ground should slope away
from the house.) Water in the basement can result from the
lack of gutters or a water flow toward the house. Water
leaks in pipes or around tubs and sinks can provide a place
for biological pollutants to grow.
- Put
a plastic cover over dirt in crawlspaces to prevent moisture
from coming in from the ground. Be sure crawlspaces are
well-ventilated.
- Use
exhaust fans in bathrooms and kitchens to remove moisture
to the outside (not into the attic). Vent your clothes dryer
to the outside.
- Turn
off certain appliances (such as humidifiers or kerosene
heaters) if you notice moisture on windows and other surfaces.
- Use
dehumidifiers and air conditioners, especially in hot, humid
climates, to reduce moisture in the air, but be sure that
the appliances themselves don't become sources of biological
pollutants.
- Raise
the temperature of cold surfaces where moisture condenses.
Use insulation or storm windows. (A storm window installed
on the inside works better than one installed on the outside.)
Open doors between rooms (especially doors to closets which
may be colder than the rooms) to increase circulation. Circulation
carries heat to the cold surfaces. Increase air circulation
by using fans and by moving furniture from wall corners
to promote air and heat circulation. Be sure that your house
has a source of fresh air and can expel excessive moisture
from the home.
- Pay
special attention to carpet on concrete floors. Carpet can
absorb moisture and serve as a place for biological pollutants
to grow. Use area rugs which can be taken up and washed
often. In certain climates, if carpet is to be installed
over a concrete floor, it may be necessary to use a vapor
barrier (plastic sheeting) over the concrete and cover that
with sub-flooring (insulation covered with plywood) to prevent
a moisture problem.
- Moisture
problems and their solutions differ from one climate to
another. The Northeast is cold and wet; the Southwest is
hot and dry; the South is hot and wet; and the Western Mountain
states are cold and dry. All of these regions can have moisture
problems. For example, evaporative coolers used in the Southwest
can encourage the growth of biological pollutants. In other
hot regions, the use of air conditioners which cool the
air too quickly may prevent the air conditioners from running
long enough to remove excess moisture from the air. The
types of construction and weatherization for the different
climates can lead to different problems and solutions.
Maintain
and Clean All Appliances That Come In Contact With Water
- Have
major appliances, such as furnaces, heat pumps and central
air conditioners, inspected and cleaned regularly by a professional,
especially before seasonal use. Change filters on heating
and cooling systems according to manufacturer's directions.
(In general, change filters monthly during use.) When first
turning on the heating or air conditioning at the start
of the season, consider leaving your home until it airs
out.
- Have
window or wall air-conditioning units cleaned and serviced
regularly by a professional, especially before the cooling
season. Air conditioners can help reduce the entry of allergy-causing
pollen. But they may also become a source of biological
pollutants if not properly maintained. Clean the coils and
incline the drain pans according to manufacturer's instructions,
so water cannot collect in pools.
- Have
furnace-attached humidifiers cleaned and serviced regularly
by a professional, especially before the heating season.
- Follow
manufacturer's instructions when using any type of humidifier.
Experts differ on the benefits of using humidifiers. If
you do use a portable humidifier (approximately 1 to 2 gallon
tanks), be sure to empty its tank every day and refill with
distilled or demineralized water, or even fresh tap water
if the other types of water are unavailable. For larger
portable humidifiers, change the water as recommended by
the manufacturer. Unplug the appliance before cleaning.
Every third day, clean all surfaces coming in contact with
water with a 3% solution of hydrogen peroxide, using a brush
to loosen deposits. Some manufacturers recommend using diluted
household bleach for cleaning and maintenance, generally
in a solution of one-half cup bleach to one-gallon water.
When using any household chemical, rinse well to remove
all traces of chemical before refilling humidifier.
- Empty
dehumidifiers daily and clean often. If possible, have the
appliance drip directly into a drain. Follow manufacturer's
instructions for cleaning and maintenance. Always disconnect
the appliance before cleaning.
- Clean
refrigerator drip pans regularly according to manufacturer's
instructions. If refrigerator and freezer doors don't seal
properly, moisture may build up and mold can grow. Remove
any mold on door gaskets and replace faulty gaskets.
Clean
Surfaces
- Clean
mold surfaces, such as showers and kitchen counters.
- Remove
mold from walls, ceilings, floors, and paneling. Do not
simply cover mold with paint, stain, varnish, or a moisture-proof
sealer, as it may resurface.
- Replace
moldy shower curtains, or remove them and scrub well with
a household cleaner and rinse before re-hanging them.
Dust
Control
Controlling
dust is very important for people who are allergic to animal
dander and mites. You cannot see mites, but you can either
remove their favorite breeding grounds or keep these areas
dry and clean. Dust mites can thrive in sofas, stuffed chairs,
carpets, and bedding. Open shelves, fabric wallpaper, knickknacks,
and Venetian blinds are also sources of dust mites. Dust mites
live deep in the carpet and are not removed by vacuuming.
Many doctors suggest that their mite-allergic patients use
washable area rugs rather than wall-to-wall carpet.
- Always
wash bedding in hot water (at least 130° F "one
hundred degrees Fahrenheit") to kill dust mites. Cold
water won't do the job. Launder bedding at least every 7
to 10 days.
- Use
synthetic or foam rubber mattress pads and pillows, and
plastic mattress covers if you are allergic. Do not use
fuzzy wool blankets, feather or wool-stuffed comforters,
and feather pillows.
- Clean
rooms and closets well; dust and vacuum often to remove
surface dust. Vacuuming and other cleaning may not remove
all animal dander, dust mite material, and other biological
pollutants. Some particles are so small they can pass through
vacuum bags and remain in the air. If you are allergic to
dust, wear a mask when vacuuming or dusting. People who
are highly allergy-prone should not perform these tasks.
They may even need to leave the house when someone else
is cleaning.
Before
You Move
Protect
yourself by inspecting your potential new home. If you identify
problems, have the landlord or seller correct them before
you move in, or even consider moving elsewhere.
- Have
professionals check the heating and cooling system, including
humidifiers and vents. Have duct lining and insulation checked
for growth.
- Check
for exhaust fans in bathrooms and kitchens. If there are
no vents, do the kitchen and bathrooms have at least one
window apiece? Does the cook top have a hood vented outside?
Does the clothes dryer vent outside? Are all vents to the
outside of the building, not into attics or crawlspaces?
- Look
for obvious mold growth throughout the house, including
attics, basements, and crawlspaces, and around the foundation.
See if there are many plants close to the house, particularly
if they are damp and rotting. They are a potential source
of biological pollutants. Downspouts from roof gutters should
route water away from the building.
- Look
for stains on the walls, floor or carpet (including any
carpet over concrete floors) as evidence of previous flooding
or moisture problems. Is there moisture on windows and surfaces?
Are there signs of leaks or seepage in the basement?
- Look
for rotted building materials which may suggest moisture
or water damage.
- If
you or anyone else in the family has a pet allergy, ask
if any pets have lived in the home.
- Examine
the design of the building. Remember that in cold climates,
overhanging areas, rooms over unheated garages, and closets
on outside walls may be prone to problems with biological
pollutants.
- Look
for signs of cockroaches.
Where
Biological Pollutants May Be Found In The Home
1.
Dirty air conditioners
2. Dirty humidifiers and/or dehumidifiers
3. Bathroom without vents or windows
4. Kitchen without vents or windows
5. Dirty refrigerator drip pans
6. Laundry room with unvented dryer
7. Unventilated attic
8. Carpet on damp basement floor
9. Bedding
10. Closet on outside wall
11. Dirty heating/air conditioning system
12. Dogs or cats
13. Water damage (around windows, the roof, or the basement)
Warning!
Carefully read instructions for use and any cautionary labeling
on cleaning products before beginning cleaning procedures.
- Do
not mix any chemical products. Especially, never mix cleaners
containing bleach with any product (such as ammonia) which
does not have instructions for such mixing. When chemicals
are combined, a dangerous gas can sometimes be formed.
- Household
chemicals may cause burning or irritation to skin and eyes.
- Household
chemicals may be harmful if swallowed, or inhaled.
- Avoid
contact with skin, eyes, mucous membranes and clothing.
- Avoid
breathing vapor. Open all windows and doors and use an exhaust
fan that sends the air outside.
- Keep
household chemicals out of reach of children.
- Rinse
treated surface areas well to remove all traces of chemicals.
Correcting
Water Damage
What if
damage is already done? Follow these guidelines for correcting
water damage:
- Throw
out mattresses, wicker furniture, straw baskets and the
like that have been water damaged or contain mold. These
cannot be recovered.
- Discard
any water-damaged furnishings such as carpets, drapes, stuffed
toys, upholstered furniture and ceiling tiles, unless they
can be recovered by steam cleaning or hot water washing
and thorough drying.
- Remove
and replace wet insulation to prevent conditions where biological
pollutants can grow.

(O3)
|
Formed
when reactive organic gases (ROG) and nitrogen oxides
react in the presence of sunlight. ROG sources include
any source that burns fuels (e.g., gasoline, natural
gas, wood, oil);solvents; petroleum processing and
storage; and pesticides
|
Breathing
difficulties, lung tissue damage, damage to rubber
and some plastics.
|
Reduce
motor vehicle reactive organic gas (ROG) and nitrogen
oxide emissions through emissions standards, reformulated
fuels, inspections programs, and reduced vehicle use.
Limit ROG emissions from commercial operations and
consumer products. Limit ROG and NOx emissions from
industrial sources such as power plants and refineries.

|
Respirable
Particulate Matter (PM10)
|
Road
dust, windblown dust, agriculture and construction,
fireplaces. Also formed from other pollutants (acid
rain, NOx, SOx, organics). Incomplete combustion of
any fuel.
|
Increased
respiratory disease, lung damage, cancer, premature
death, reduced visibility, surface soiling.
|
Control
dust sources, industrial particulate emissions, wood
burning stoves and fireplaces. Reduce secondary pollutants
which react to form PM10. Conserve energy
|
|
Fine
Particulate Matter (PM2.5)
|
Fuel
combustion in motor vehicles, equipment, and industrial
sources; residential and agricultural burning. Also
formed from reaction of other pollutants (acid rain,
NOx, SOx, organics).
|
Increases
respiratory disease, lung damage, cancer, premature
death; reduced visibility; surface soiling.
|
Reduce
combustion emissions from motor vehicles, equipment,
industries, and agriculture and residential burning.
Precursor controls, like those for ozone, reduce fine
particle formation in the atmosphere.
|
|
Carbon
Monoxide (CO)
|
Any
source that burns fuel such as automobiles,trucks,
heavy construction equipment and farming equipment,
residential heating.
|
Chest
pain in heart patients, headaches, reduced mental
alertness
|
Control
motor vehicle and industrial emissions. Use oxygenated
gasoline during winter months. Conserve energy.
|
|
Nitrogen
Dioxide (NO2)
|
See
Carbon Monoxide
|
Lung
irritation and damage. Reacts in the atmosphere to
form ozone and acid rain
|
Control
motor vehicle and industrial combustion emissions.Conserve
energy.
|
|
Lead
|
Metal
smelters, resource recovery, leaded gasoline, deterioration
of lead paint
|
Learning
disabilities, brain and kidney damage
|
Control
metal smelters, No lead in gasoline. Replace leaded
paint with non-lead substitutes.
|
|
Sulfur
Dioxide (SO2)
|
Coal
or oil burning power plants and industries, refineries,
diesel engines
|
Increases
lung disease and breathing problems for asthmatics.
Reacts in the atmosphere to form acid rain.
|
Reduce
the use of high sulfer fuels (e.g., use low sulfer
reformulated diesel or natural gas). Conserve energy.
|
|
Visibility
Reducing Particles
|
See
PM2.5
|
Reduces
visibility ( e.g., obscures mountains and other scenery),
reduced airport safety, lower real estate value, discourages
tourism
|
See
PM2.5
|
|
Sulfates
|
Produced
by the reaction in the air of SO2 ( see
SO2 sources), a component of acid rain
|
Breathing
difficulties, aggravates asthma, reduced visibility
|
See
SO2
|
|
Hydrogen
Sulfide
|
Geothermal
power plants, petroleum production and refining, sewer
gas
|
Nuisance
odor (rotten egg smell), headache and breathing difficulties
(higher concentrations)
|
Control
emissions from geothermal power plants, petroleum
production and refining, sewers, sewage treatment
plants
