Breathe and
Die Asbestos

Subic,
Philippines (January 5, 2018) ---Alfonso Tabanyag, 65 has been looking forward
to the birth of his first grandson. Donning his favorite Chicago Bulls cap, he
stepped out to take a taxicab to the hospital where his daughter gave birth.
Suddenly he felt being choked, his lung seemed bursting and he was gasping for
air holding his chest.
Brought to
the emergency room not far from the ward where his grandson lay sleeping, he
was told he was suffering from severe Asbestosis, a killing phenomenon for
people who have long been exposed to asbestos or its components.
Tabanyag is
one of more than 1,000 worker-victims of Asbestosis in this once-sprawling US
military base, who worked for 25 years insulating the facilities from dreaded
military attacks that could make the base erupt into an inferno.
For
Tabanyag, breathing from now on will be a struggle.
There are
thousands more like him, says the International Labor Organization (ILO) who
reported in its September labor international updates that cancer-causing
asbestos and its particles continue to maim men, women and children alike
worldwide.
It is
urgently pushing for the adoption of more stringent standards on
industrial uses of asbestos.
Fiber-Mineral the Only Kind
Asbestos is
a fibrous mineral formerly used a great deal as heat and fire-resistant
insulating material. This threadlike mineral fiber has more than 2,000 uses
which is why many countries have not totally junked it.
From being
fire resistant to good conductor of heat and electricity, ILO said it is probably
found in almost 95 percent of all houses worldwide because it is a component of
cement.
It is used
in housing, fireproofing, and automobile parts especially as brake lining and
gaskets, theater curtains, roofing, electrical insulation, caulking, cement
pipes, floor tiles, and plastics. In manufacturing firms, it is used to
insulate boilers, and as filters that resist chemicals.
As a
mineral, asbestos is hydrated silicates from the mineral silica and comes from
metamorphic rock. It was discovered in 1774 by Abraham G. Werner, a
Mineralogist. It was used till 1931 before doctors noted the ill effects it
causes to people.
Russia and
Canada remain the biggest producers worldwide.
Asbestosis
In its
September 2016 report, the ILO said that asbestos does not only cause
Asbestosis, a serious lung disease, but also Bronchial Cancer and Mesothelioma
(cancer of the Pleura and Peritoneus) which are fatal.
Asbestosis
is a disease that blocks the lungs with thick fibrous tissues. Besides causing
difficulty and shortness of breath, it causes swollen fingers and toes.
To those
directly working with it like Tabanyag, asbestos causes Bronchogenic Cancer,
the cancer of the bronchial tubes.
ILO also
announced that cigarette-smoking workers who are exposed to asbestos have high
rick to cancer.
People
exposed to asbestos such as those working in asbestos mines, industrial
facilities, insulation fabrication and military installations are the most
likely to develop such diseases, ILO said.
According to
Dr. Tony Smith, Deputy Editor of the British Medical Journal, asbestosis causes
widespread scarring of the lungs and tends to progress even when exposure to it
is discontinued.
The disease
causes breathlessness and a dry cough eventually leading to severe disability
and death.
Victims
usually start experiencing asbestosis symptoms after seven to ten years of
exposure.
Smith
clarified that, even today, scientists do not know how asbestos causes disease.
Medical
researchers though explain that fibers longer than 5 to 10 micrometers increase
the risk of illness, he said.
An extremely
short period of inhaling large amounts of asbestos fibers may result in
Mesethelioma, he added.
Other Asbestos-Induced Diseases
Smith
explained that mesothelioma is a result of a malignant tumor of the pleura
or the peritoneum.
The Pleura
is a membrane that surrounds the lungs while the Peritoneum is a membrane that
lines the abdominal cavity and covers the abdominal organs.
He lamented
that there is no treatment for the disease which usually leads to death within
one or two years.
Another
disease that arises from exposure to asbestos, the ILO reported, is Bilateral
Diffuse Pleural Thickening wherein the outer and inner layers of the pleura
become thickened and become calcified or “bony”. This causes fluid to
accumulate in between the cavities and restricts the ability of the lungs to
expand resulting in shortness of breath.
The American
Society of Plastic and Reconstructive Surgeons bared that asbestos is also the
cause of pleural plagues.
These are
thickened tissues confined to the outer layer of the pleura. While this does
not cause disability, it can develop into an asbestos-related disease.
Jekyll and Hyde
Occupationally,
millions are exposed to inhalation of significant amounts of asbestos dust
during the ordinary workday. This is because there is still a growing world
production of asbestos.
Some 5
million tons were produced last year compared to only 675,000 tons in 1940,
added the ILO.
While using
asbestos for insulation got abated, the mineral is still vital in production of
cement and as ingredient to some 1,000 other industrial products.
No
technologically alternative materials can replace asbestos today, ILO admitted
as it saves millions of lives when manufactured into fire protection and brake
linings. But, it is also a threat especially to the health of industrial
workers, thus dubbed “Dr. Jekyll and Mr. Hyde”.
The ILO
recommends that governments should prescribe occupational exposure limits with
corresponding testing measures, and that an international safety measure
standard be adopted. Such measures must include dust control, constant
monitoring of workers’ health, and the use of adequate protective clothes and
masks.
