ASBESTOS
What is asbestos?
Asbestos is a naturally occurring strong mineral fiber that is resistant to heat and has many desirable
properties. Because asbestos fibers are resistant to heat and most chemicals, they have been used as
insulation materials in many residential and commercial buildings throughout the country. Asbestos
fibers are found in nature and float easily. Nearly everyone is exposed to asbestos at some time during
their life.
How much asbestos causes illness?
Most people do not become ill from the asbestos they are exposed to. Asbestos exposure becomes a
health concern when high concentrations of asbestos fibers are inhaled over a long time period. People
who become ill fi-om asbestos are almost always those who are exposed on a day-to-day basis in a job
where they work directly with the material. As a person’s exposure to fibers increases, either by
breathing more fibers or by breathing fibers for a longer time, that person's risk of disease also
increases. It can take anywhere from 10 to 40 years for someone to develop an asbestos-related illness
after their exposure. Disease is very unlikely to result from a single, high-level exposure, or from a
short period of exposure to lower levels.
What are some illnesses caused by prolonged or concentrated exposure to asbestos in the
workplace?
Asbestosis -is a serious, progressive disease associated with long-term exposure to asbestos that
causes damage (called 'scarring') to lung tissue. The symptoms of the disease (like shortness of breath)
can be managed under the care of a doctor.
Lung cancer - Asbestos is one of the leading causes of all types of lung cancers among nonsmokers,
and asbestos-exposed smokers have dramatically high rates of this disease.
Malignant mesothelioma -a rare progressive cancer of the tissue lining the chest or abdomen for
which asbestos and similar fibers is the only known cause.
What are some things that can be done to limit exposure?
For the general public, the best way to avoid exposure is to avoid breathing in dust as much as
possible. We do not know if all of the dust has asbestos. If there is asbestos in the dust, short-term
exposures are unlikely to cause harm.
