ASBESTOS REMOVAL - LOS ANGELES, CALIFORNIA
Here's where to look for asbestos and what to do
if you find it:
Heating ductwork. Some
ducts, particularly in Southern California, are made largely of
asbestos; other metal ducts are wrapped with a cellulose-asbestos,
air-cell insulation. Both look a bit like off-white corrugated
cardboard; asbestos-sheeting insulation has a similar appearance but
not the corrugations. In addition, registers may have asbestos
Ductwork made of asbestos is a major concern because
when it begins to deteriorate, fibers are blown into the house. Talk
with an asbestos abatement contractor about removal. Replacement is
Wrapped ducts should be removed if wrapping is
friable. A stop-gap measure for duct wrapping that's sound is to
have it encapsulated.
The furnace may have an
asbestos lining at the base or sit on an asbestos pad. A special
asbestos cloth may join furnace or boiler to ductwork. If any of
these are exposed to damage, they should be encapsulated or removed.
To date, most research has centered around asbestos
workers and their families, with whom it has been proven chronic
breathing of asbestos fibers causes permanent scarring of the lungs
(“asbestosis”), lung cancer and mesothelioma. Problems may show up
30 to 40 years after exposure.
A growing number of doctors and researchers are
concerned about the long-term effects of low-level exposure.
As a rule, asbestos fibers tend to attach themselves
permanently to lung tissue; long-term, residual accumulation might
catch up with you. The prudent assumption, voiced by Lee Thomas,
former Administrator of the EPA , is that there is “no safe
exposure” to airborne asbestos.
Why use flexible air ducts?
You may wonder why it is important to have insulated
flex ducts in your home. Or, does this type of duct make a
difference vs. standard ducting? The ducts we install are UL181
listed, have an R-Value of 6 and come with a 10 year warranty. Why
insulated duct? The insulation in the ducting will prevent
condensation from forming on the duct. Condensation forming on the
duct is not a good thing. Another benefit of the insulated flexible
ducting is that it further reduces any “air noise” caused by the
exhaust fan, so your ventilation system works even quieter.
