Asbestos -
Who is at risk?
Nearly
everyone is exposed to asbestos at some time during
their life. However, most people do not become ill from
their exposure. People who become ill from asbestos
are usually those who are exposed to it on a regular
basis, most often in a job where they work directly
with the material or through substantial environmental
contact.
Since
the early 1940s, millions of American workers have been
exposed to asbestos. Health hazards from asbestos fibers
have been recognized in workers exposed in shipbuilding
trades, asbestos mining and milling, manufacturing of
asbestos textiles and other asbestos products, insulation
work in the construction and building trades, brake
repair, and a variety of other trades. Demolition workers,
drywall removers, and firefighters also may be exposed
to asbestos fibers. As a result of Government regulations
and improved work practices, today’s workers (those
without previous exposure) are likely to face smaller
risks than did those exposed in the past.
Although
it is known that the risk to workers increases with
heavier exposure and longer exposure time, investigators
have found asbestos-related diseases in individuals
with only brief exposures. Generally, those who develop
asbestos-related diseases show no signs of illness for
a long time after their first exposure. It can take
from 10 to 40 years for symptoms of an asbestos-related
condition to appear.
There
is some evidence that family members of workers heavily
exposed to asbestos face an increased risk of developing
mesothelioma. This risk is thought to result from exposure
to asbestos fibers brought into the home on the shoes,
clothing, skin, and hair of workers. This type of exposure
is called paraoccupational exposure. To decrease these
exposures, people exposed to asbestos at work are required
to shower and change their clothing before leaving the
workplace.
