Acoustic Asbestos Ceiling
Removal, Is It Necessary?
Takuya Hikichi
Homeowners with acoustic
asbestos ceiling question about
the effects of asbestos
contained within its materials
that if inhaled would cause
serious health hazards.
If material contains more
than 1% of asbestos, EPA
defines as it's containing.
However, asbestos can only be
positively identified by
microscope. Many of the homes
built prior to 1980s observe
acoustic asbestos ceilings, and
the removal of acoustic
asbestos ceiling has become
commonly done for environmental
safety precautions.
Many homes contain acoustic
asbestos ceiling in their
bedrooms, living rooms, with
spray-applied textures.
However, asbestos materials are
also in pipe insulation,
shingles, floor tile, mastics,
roofing, structural steel
fireproofing, etc.
University of Arizona Dept.
of Risk Management and Safety
explains the hazards of
asbestos in the following
manner.
"Asbestos is a respiratory
hazard and
espiratory/gastrointestinal
carcinogen. Exposure to
asbestos occurs when reparable
fibers are released into the
air and then inhaled. Since
exposure occurs when asbestos
is inhaled, the best way to
prevent exposure is to prevent
asbestos fibers from becoming
airborne.
Asbestos containing
materials are therefore divided
into two categories: friable
and non-friable. Friable means
that a material is able to be
reduced to powder by hand
pressure. Asbestos containing
materials that are friable, by
their nature, have a much
greater tendency to release
fibers. They require specific
control measures to prevent
releasing fibers into the air.
Conversely, non-friable
asbestos containing materials,
by their nature, do not want to
give up their fibers into the
air. This class of materials
must be mechanically impacted
(power tools such as sanders,
drills, chippers, saws, etc.)
to release fibers. Asbestos
containing textured ceiling
materials is a friable
material."
Is Asbestos Ceiling Removal
Hazardous?
Although breathing of
asbestos fibers post threats to
human health, unless air
contamination occurs to cause
releasing of asbestos airborne
and becomes friable, it would
not affect environment.
Moreover, several layers of
paint applied to the ceiling
over the years serves to “seal”
acoustic asbestos ceiling and
withhold materials from
dangerously contacting
occupants.
Homeowners should not
unnecessarily impact the
ceiling by placing fixtures
onto the ceiling or by moving
objects surrounding the
environment. When done
improperly, asbestos becomes
into airborne and increases the
risk of releasing its fibers to
be inhaled. Because asbestos
fibers are small and light,
they can be suspended in the
air for long periods of time.
Therefore, unprofessional
management of acoustic asbestos
ceiling removal should not be
preceded and a licensed
asbestos abatement professional
must conduct removal.
