DANGERS
OF ASBESTOS
A Short
History of Asbestos and Mesothelioma
Well over a century ago, asbestos
was seen as an ideal building material, it was an excellent insulator,
fireproof, and relatively inexpensive. During the twentieth
century, some 30 million tons of asbestos was used in the construction
of industrial sites, office buildings, schools, shipyards homes,
and everyday items such as ironing boards, dryers, toasters, and
low-density insulation products. Beginning at the turn of
the 20th century, researchers began to see a correlation between
the unusually large numbers of deaths and lung problems in asbestos
mining towns.
In the 1930's, numerous and well-known
medical journals published scientific studies that linked asbestos
to cancer. In 1935, the American Journal of Cancer published "Pulmonary
Asbestosis: Carcinoma of the Lung in Asbesto-Silicosis." In 1955,
scientists confirmed what they had long suspected; there was a unmistakable
connection between the ingestion of asbestos fibers and the development
of certain forms of lung cancer (what later came to be known as
mesothelioma).
Despite the growing evidence of asbestos’s
health risks, manufacturers and companies continued its use for
many of their projects. In all likelihood, these manufacturers were
aware of the potential health risks but choose to ignore them. These
same companies also ignored using safer alternative materials like
fiberglass that were then being developed. Unfortunately, the victims
were, for the most part, men of working families who had no knowledge
of the potential health risks they faced.
The first lawsuits against the manufacturers
and companies responsible for asbestos related cancer were brought
to suit in 1929. Since then, numerous lawsuits have been filed against
those responsible for asbestos use and proliferation. Many if these
cases have resulted in large settlements for victims and the families
of victims of mesothelioma.
What
is Asbestos?
Asbestos refers to a group of naturally
occurring silicate minerals whose fibers are strong, durable, and
resistant to heat and fire. They are long, thin and flexible, allowing
them to be turned into cloth.
Of the many forms of asbestos fibers,
three are primarily used for commercial purposes:
- Chrysotile, or white asbestos,
has been very widely used in the US. It is white-gray in color
and found in serpentine rock.
- Amosite or brown asbestos.
- Crocidolite or blue asbestos.
Amphibole asbestos (e.g. amosite
and crocidolite) is very dangerous because of its dusty, needlelike
fibers. Individuals that are exposed to this type of asbestos ingest
the dust, which then becomes trapped in the lungs indefinitely.
Over time, this can lead to asbestosis or malignant mesothelioma.
Asbestos fibers not often used for
commercial purposes include tremolite, actinolite and anthophyllite.
However, these fibers are occasionally used as contaminants in asbestos-containing
products.
Which Products
Contain(ed) Asbestos?
Asbestos-containing products are
used to contain heat—otherwise known as thermal insulation. Most
insulation materials before the mid-1970s did contain some degree
of asbestos. Countless products have, at one time or another, contained
asbestos, including (but not limited to): thermal seals, insulating
cement, asbestos cloth, asbestos cement pipe, pipe-covering, refractory
and boiler insulation materials, packing materials, fireproofing
spray, transite board, gaskets, insulating block, joint compound,
duct insulation for heating, vinyl floor tile, ceiling tile, adhesives,
mastics, coatings, roofing products, acoustical textures, insulated
electrical wire and panels, ventilation and air conditioning (HVAC)
systems, and brake and clutch assemblies.
Does Asbestos
Still Pose a Health Risk?
Asbestos continues to be a health
risk because it may still be part of buildings and products that
were built decades ago. Asbestos-containing products may still be
in industrial facilities, buildings, ships, and other structures
and products where the fibers can become airborne. The ingestion
of these fibers is the cause of malignant mesothelioma.
More importantly, malignant mesothelioma
can develop up to 40 years after the initial exposure. The incidence
of mesothelioma rises with the intensity and duration of exposure
to asbestos. Cases have been documented of mesothelioma among people
with very little exposure to the dangerous asbestos fibers. Many
of those who are being diagnosed with mesothelioma today were unknowingly
exposed during their time in the Navy many years ago.
Tradesmen who have a risk of asbestos
exposure and mesothelioma include:
- Insulators (also known as asbestos
workers)
- Boilermakers who constructed boilers
filled with insulation
- Plumbers, pipe fitters, and steamfitters
who worked in poorly ventilated compartments with large quantities
of insulation
- Plasterers
- Shipyard workers and Navy personnel
- Electricians and mechanics
- Bricklayers, millwrights, carpenters,
etc.
- Steel workers and refinery and
other industrial workers
- Maintenance workers and laborers
If you or someone you know has a
health risk associated with asbestos exposure, you’re entitled to
know your legal rights.
