Because so many people asked for copies of Pat's article, which is very
good (even thou it does not contain Pat's usual humor), I have taken
the liberty of reproducing the article here (without permision of
Bird Talk)
From Bird Talk, March 1989
AIRBORNE TOXINS
By Patricia Walz
Responsible parents learn how to successfully childproof their
homes to avoid exposing their children to household poisons. Like
children, out pet birds depend on us to provide them with a safe
environment. We wisely place Polly securely in her cage (or take
other precautions) to protect her from household hazards such as
hot kitchen range tops, toxic plants and open windows, but we must
also remember to shield out birds from another danger, airborne
contaminants.
Do you know why miners used to bring small birds, such as
canaries, into the mine shafts with them? If the miners noticed
the birds experiencing any respiratory problems, they knew
poisonous gases were present, so they immediately left the mine.
Because we do not want out pet birds to serve as toxicity monitors,
it behooves us to be sure that we have no poisonous funes in out
homes.
The avian respiratory system differs greatly from that of humans
and other animals. Birds require larger amounts of oxygen more
frequently. This compensates for their higher metabolic and helps
them fly. At rest, an average cockatiel breathes 100 to 124 times
per minute. Humans normally breathe between 12 and 16 times per
minute.
Contaminates in the air that may simply irritate out respiratory
system can kill out avian friends. Have you ever, even for a short
trip, placed you bird in the trunk of your car? I know of a
beautiful sun conure that was killed this way. Sunny was placed in
his owner's automobile trunk for a 15 minute trip. If a vehicle
has an inadequate exhaust system, the car's interior and trunk may
contain dangerous levels of carbon monoxide fumes. Carbon monoxide
blocks the flow of oxygen to body cells. It is colorless,
odorless, undetectable to the senses and lethal! With enough
exposure death will occur.
Tobacco smoke also emits carbon monoxide. If you smoke
cigarettes (or any tobacco product), assess where you smoke, and
where you keep your birds. Because they live in open-air cages,
birds that live with people who smoke may be forced to inhale
second-hand smoke. A bird can not reposition its cage or ask you
to stop smoking. For your birds' health, exclude the use of
tobacco products in your home. If you must smoke, air cleaners
placed in forced-air heating or central airconditioning systems, or
filters that remove large particles from the air may improve the
air quality in your home.
NONSTICK SURFACES
It can happen suddenly. A family eating dinner forgets about
the empty Teflon-coated pan on the stove. Within minutes, the pan
reaches 280 degrees Celsius (approximately 536 degrees Fahrenheit)
and begins to emit toxic fumes. During early exposure, the pet
birds begin blinking their eyes; their breathing becomes labored.
As if attempting an escape, they flap wildly in their cages, then
convulse. Death follows within 15 to 20 minutes.
Nonstick cookware containing PTFE (polytetrafluoroethlene), such
as Teflon and Silverstone, probably will not harm your birds if
used under normal cooking conditions. When a pan overheats,
however, the coating emits poisonous fumes. In most cases, empty
pans or those filled with water are likely to overheat to dangerous
levels. When foods, oils or butter warming in a pan begin to burn,
we are usually alerted to remove the pan from the cook top or oven
before the nonstick surface overheats to dangerous levels.
Nonstick-coated drip pans that fit under the burners on cook tops
will reach excessive temperatures whenever you cook. If you have
birds in your home, do not ever use these drip pans.
Take an inventory of other non-stick products that you use
routinely. Did you know, for example that many irons and ironing
board covers are coated with Teflon? Check out your cookie sheets,
waffle irons, popcorn poppers and curling irons, as well. Nonstick
coatings containing PTFE have many different names - not just
Teflon, Supra and Silverstone - so read labels carefully before
using or purchasing.
Birds poisoned by PTFE fumes usually die quickly, but sometimes
they live for several days after exposure. Be aware of this danger
and exercise prudent care when ironing or cooking with nonstick
cookware (cooking at moderate temperatures) may help you avoid this
horrible tragedy. Because we control most of our birds exposure to
toxins in the air, we can take other positive steps to avoid
exposing our birds to danger.
OTHER KITCHEN HAZARDS
Do not keep your birds in the kitchen. Cooking orders, grease,
steam and smoke can all act as irritants and/or toxins to your
pets. A self-cleaning oven in its cleaning mode incinerates food
deposits by heating to approximately 800 degrees Fahrenheit, which
may cause the burning grease to emit carbon monoxide and other
toxic gasses.
Normally, kitchen cabinets contain cleaning supplies. I now
keep most of these dangerous supplies in my garage or utility room.
I securely close up those supplies remaining in my kitchen.
Many homes have gas ranges. These can leak nitrogen dioxide, a
gas that can seriously irritate the respiratory tract. If you own
a gas range, you can help avoid problems by installing a range hood
vented to the outside, adjusting burner flames correctly (they
should be blue, not orange), using kitchen exhaust fans and opening
a window when cooking. If you by a new gas range, try to get one
with "pilotless ignition."
HEATING YOUR HOME
Kerosene or gas heaters also emit carbon monoxide and nitrogen
oxides. Although I normally avoid using them in my home, I must
occasionally (such as during power outages) use these heat sources.
If you, too, must use gas or kerosene heaters,, increase the
circulations of fresh air in the bird room, and keep one window at
least partially open. If possible, do not run kerosene- or
gas-fueled heaters continuously. Do not use an improperly
maintained heater, and never use any components that do not meet
manufacturer's specifications.
Another heat source that might add airborne contaminants into
the home is the fireplace. Treated wood may emit harmful fumes.
Keep your flue, and chimney in good working order; have a
professional check, clean and repair you fireplace and chimney each
year before you light any fires.
HEALTHY LEAKS
In out efforts to conserve out nation's energy sources, many of
us have worked hard to make out homes more energy efficient. When
we added insulation, storm doors and windows, caulking and
weather-stripping, we make out homes more airtight, which trapped
pollutants inside. The ducts and vents of central air-conditioning
and heating can carry the fumes or pollutants from one room to the
other. If you use a product that emits toxic fumes, you may
unknowingly expose you bird to harm, even thou the bird is in
another room of the house.
If you house is airtight, you may have a pollution problem.
Stale odors may linger longer in your home. Your children may
frequently get colds or sinus problems. Your eyes may smart and
tear. Look for condensation on windows or mildew on the ceilings
of your home. These signs may indicate that you house lacks
essential circulation of fresh air, which could increase the level
of airborne contaminants. Routinely increases your air circulation
by opening windows. Do this in every season of the year, even if
you open them just a crack. Be sure, however, to place your birds
out of any drafts.
GASES
In some areas, Radon gas is a dangerous indoor pollutant,
seeming from the earth into homes above. Exposure to this
colorless odorless gas can cause cancer. The local health
departments in affected areas may have testing equipment available,
or you may wish to use a home test kit, which you can purchase at
some hardware stores.
Formaldehyde in the home also gives out some fumes. This
chemical has been used in insulation foam, as a preservative in
plywood and particleboard, and in textiles, such as draperies and
carpets. Mobile homes can be particularly affected because of the
extensive use of treated products in their manufacture. Any new
homes, particularly if it contains new carpets, drapes, furniture
and wooden cabinets, will have a higher level of formaldehyde that
older homes because the fumes dissipate with time.
If you are concerned about the level of formaldehyde in your
home, you can purchase a kit to measure the level of the gas in
your home from companies that specialized in air-pollution control.
If you believe the level is too high for your birds' safety,
trained personnel at these companies can help you determine the
best solution to your problem.
INSECT CONTROL
Many of us routinely use chemicals to exterminate insects or
rodents. Pesticides can be toxic to our avian friends. Birds have
died, for example, after being exposed to diazanon in products like
Baygon.
If your household also includes cats or dogs, fleas may have
invaded your home. When you bathe your cat or dog with
flea-killing soap or five it a new flea collar, keep the animal
away from your birds; the flea-killing fumes are toxic to birds.
If you fog for insects in one part of the house, turn off your
central air-conditioning or heating system, and put your birds in
an area where they can avoid exposure. Better yet, get them
completely out of the house for 48 hours. I take my birds to work
when the pest-control people treat my home.
You can control insects and other pest without poisoning your
birds, if you vacuum frequently, pick up spilled food immediately
and use safe products. Ask your avian veterinarian to advise you
on which products to avoid and which to use. Most professional
exterminators will cooperate and work with your veterinarian.
Follow your veterinarian's suggestions exactly. Do not vary from
your exterminator's instructions; if instructed to remove birds
from your house during spraying or fogging, do not return them
earlier than the prescribed time.
CAUTION!
A bird's air sacs comprise and extensive area of its inner body.
Because the exchange surface of the avian lung is a least 10 times
greater than the human lung, the potential for absorbing harmful
pollutants is much greater in birds that in humans. Keeping birds
in certain rooms in our homes, such as kitchens and bathrooms,
increases their chances of breathing airborne contaminants. If you
must house your bird in one of those rooms, remove the bird before
you use potentially poisonous substances, such as oven cleaner or
toilet bowl cleaner.
When we do projects around the house, we may forget that the
chemicals we use may seriously harm or kill our feathered friends.
A friend of mine was stripping some wood furniture in the company
of her Amazon parrot, Poncho. Fortunately she noticed that her
bird was having trouble breathing. She quickly placed him outside
in fresh air and called her avian veterinarian for assistance. Now
when my friend strips furniture, she does it outside without
Poncho.
If you enjoy home craftwork, saw work, making model airplanes and
paint with oil-based paints, do it without the company of your pet
birds. Taking my own advice, I have switched from oils to
watercolors when I get the creative urge to paint. Do not use nail
polish (acetate) or nail polish remover (acetone) in an area where
your birds can inhale the fumes. Avoid using hair spray or other
aerosols. I have replaced aerosols in my home with pump-style or
roll-on products. Avoid using any spray chemical that might
endanger your birds; spray starch for example contains ammonia and
other toxic chemicals.
If a human might react negatively to a product, a bird will be
even more negatively affected. Most anything poisonous to humans
is poisonous to birds. If you doubt the toxicity of the product,
do not use it around birds. Remove them from the environment
whenever you clean house or paint your home.
My blue and gold macaw, KoKo enjoys following me around the
house. Normally, I allow him to do this, except when I clean my
home. He demonstrates his anger by screaming at me. He does not
understand that waxes, polish, bleach and other aids to cleaning
and disinfecting can have harmful fumes, which should not be
inhaled by birds. Many oven cleaners, for example contain lye.
Additionally, do not expose you birds to odors from pool and spa
chemicals, such as chlorine.
AVOIDING AIR POLLUTION
We can help reduce the airborne pollutants in out home in
several ways. Use potentially harmful products, such as Teflon
pans and gas-fueled space heaters, with caution. Eliminate
unnecessary items, such as tobacco products, and replace unsafe
items such as nonstick burner top plates with those that you can
use safely. Do your craft or handyman projects outdoors or in
areas where your birds will not be exposed.
Using an air cleaner may also help lower the level of
contaminants in the home. Many different types of air cleaners can
effectively remove dust particles and floating bacteria and fungi
that can cause respiratory problems in birds.
Decorating your home with hanging plants low in pollen can also
effectively clean the air in your home. Choose foliage nontoxic to
birds, such as spider plants and pothos. Not only will you add to
the beauty of your home, but you will assist in purifying the air.
Routinely airing your home by opening your windows is the
cheapest and most effective solution to indoor pollution. Leaving
some windows open a crack all the time is an excellent idea. Just
make sure that your pet birds are not in the path of a draft or
fluctuations in temperature.
Educate yourself on the dangers of airborne contaminants. The
October 1985 issue of Consumer Reports described many of these
dangers in the article "Indoor Air Pollution." You can learn even
more by writing the U.S. Environmental Protection agency, 401 M St.
S.W. Washington, D.C. 20460 or the U.S. Consumer Products Safety
Commission, 5401 Westbard St., Bethesda, MD 20207. Include a
legal-size self addressed, stamped envelope.
Signs of illness in a bird that has inhaled toxic fumes can
include vomiting, diarrhea, loss of appetite, convulsions, lack of
coordination, loss of balance, breathing difficulties (increased
respiratory rate, coughing, sneezing, openmouthed breathing, noisy
breathing), lethargy, depression, behavioral changes, seizures,
shock and death. The inhaling of any toxic material in birds is
life threatening. If your pet birds exhibit any of these signs or
have been in contact with airborne contaminants, place the bird in
fresh air, and contact your avian veterinarian immediately.
Losing a cherished pet bird is a painful experience. Keeping
your feathered friends safe from contaminations in the air should
be a routine part of birdkeeping and need not affect your
lifestyle adversely. Being aware of known toxins, recognizing
potentially poisonous substances educating family members and
exercising simple precautions can prevent tragedy.
