Finding and Fixing Hidden Dangers in Your Home
News reports feed us a steady stream of
stories on scary, invisible hazards lurking in our homes, presumably ready
strike us down at any second, but how much of it is really cause for alarm?
Which hidden dangers are serious and which aren't? And what should you do
to protect yourself and your family?
Here's a look at some of the most well-known hazards and what you should do
(or not do) about them:
Lead paint
Lead paint, when ingested, can cause lead poisoning, a condition which can
severely affect mental and physical development. High doses can be fatal.
Children under 6 are especially vulnerable. The danger is that tiny bits of
chipping or peeling paint – or even paint dust – can get onto a child's
hand, and eventually their mouth. Lead paint was banned in 1978, but in
older houses, it may still be lurking. And the older your home is, the
higher the chance it has lead paint in it.
The paint doesn't pose much of a danger if it's in good condition and
undisturbed. The danger is with paint that's chipping, cracked, damp or
peeling, or paint that's in high-use spots like window sills, doors or
stairs and railings. There can also be lead paint on old furniture or toys.
If you suspect you have lead paint in your house, hire a professional to
come to the house to assess the hazard level. If a danger is found or if
you plan on remodeling, you will need to hire someone to remove the paint.
Check the Environment Protection Agency's (EPA) website
(http://www.epa.gov) to find an accredited professional.
If you have lead paint that's intact and not an immediate danger, you can
reduce your risk by keeping paint well-maintained and undisturbed. Keep
dust at bay wiping window sills and other surfaces with a damp paper towel,
then throwing the towel away. Wash floors with soft, disposable clothes.
Avoid using abrasives or chemicals on painted surfaces. Check surfaces
regularly for signs of deterioration.
Asbestos
Asbestos can be found in a variety of places including floor tiles, pipe
insulation, insulation (especially in houses built between 1930 and 1950),
shingles, textured paint (like “cottage cheese” ceilings), and siding. In
the 1970s, its use was curtailed when it was discovered that long-term
exposure to asbestos can cause lung problems, including cancer.
Even if you have asbestos in your house, don't worry--the mere presence of
asbestos is not hazardous according to the United States Consumer Product
Safety Commission. If the asbestos-containing material is in good shape,
experts recommend that you should just leave it alone. The danger comes
when the asbestos is disturbed and fibers are released into the air.
The best way to deal with asbestos-containing materials is to inspect them
regularly. Don't touch or disturb, but look for breaks, cracks and other
signs of wear and deterioration. Make sure nothing is rubbing against the
material. Don't scrub, vacuum, or cut into anything containing asbestos.
Don't pry up floor tiles yourself and don't sand or strip flooring unless
you know that the material is asbestos-free.
If you are worried, have an asbestos professional assess your risk and make
recommendations. If you have a hazard or plan on doing a remodel that may
disturb existing asbestos, you will need to hire qualified experts to
remove and dispose of the asbestos safely. An asbestos professional may
also recommend that instead of removing it, you cover and seal it to
prevent fibers from being released into the air. Asbestos workers do not
need to be licensed, so to find an accredited professional, check with
state and local agencies. (Check EPA's website for a list of contacts for
your state.)
Radon
Radon is a naturally occurring radioactive gas that can't be seen or
smelled. Radon is formed by a breakdown of uranium in the soil and gets
into houses via cracks in foundations, gaps around pipes and open spaces
inside walls. Radon exposure is the second-largest cause of lung cancer
and, alarmingly, one out of 15 homes is estimated to have elevated
exposure, according to the Environmental Protection Agency.
To check your home, get a “short-term” test kit, available online or at
hardware or home improvement stores (tests cost about $20). If you get a
reading of 4 picocuries per liter of air, or "pCi/L,” follow up with a
long-term test kit or another short-term kit to confirm the result.
If the level remains above 4 pCi/L, you should take steps to lower the
radon level. The method that will work best for your home depends on
several factors, including what type of house and foundation you have. The
most common methods are venting and fan systems, crawl space ventilation
and sub-slab suction which draws out radon and vents it away from the
house. Sealing foundation cracks, covering exposed ground and opening
windows offer another level of protection.
After making adjustments, re-check radon levels to make sure the new
system(s) are working, and re-check annually.
Carbon Monoxide
Carbon Monoxide is an odorless, colorless and deadly gas. In concentrated
doses, it can kill in minutes. The most common ways carbon monoxide can get
into your home include: blocked chimneys, gas engines on cars, lawnmowers
or generators operating without ventilation, and malfunctioning heaters or
ovens.
To prevent carbon monoxide poisoning, try these steps:
--Install a carbon monoxide detector in the hallway near every sleeping
area. A battery-operated model will keep working during a power outage. The
detector should be installed close to the ground.
--Don't use outdoor grills inside or try to heat the house with an
appliance like an oven.
--Don't use gas-powered devices or tools inside.
--Don't leave cars running in the garage, even with the door open.
--Have a professional check your heating system and fireplace annually and
make any needed repairs. Open the chimney flue before lighting a fire.
--Keep gas appliances and wood stoves in good working order and properly
vented.
If you suspect a carbon monoxide leaks or someone is exhibiting signs of
carbon monoxide poisoning (symptom include headache, dizziness, nausea,
confusion, and coordination problems.), call 911.
