Asbestos (asbestos) is a mineral silicate compound.
(Composed of silicon and oxygen) and the manner in which the fibers are bound
together. Asbestos can be divided into two groups: serpentine fiber that looks
long and wavy. It can be woven Examples include chrysotile asbestos in this
group, another group that looks amplibole fiber straight. Needle-shaped And
brittle asbestos than in the first group. Examples in this group include
asbestos, actinolite, tremolite, anthophyllite, crocidolite and amosite.
Because asbestos is a special
feature high tensile strength and flexibility. Do not conduct electricity and
heat Have the ability to absorb high. Flame-retardant chemicals Asbestos has
been used in building products. Since ancient times, such as using a wick in
ancient China and Rome. Used in clay to fortify the ancient pottery in Finland.
As well as fire-resistant fabric for wrapping the bodies of the Roman emperors
gave the fire time.
The use of asbestos has
increased dramatically since the second World War, asbestos was used in many
industries such as roof tiles. Floor tiles, pipes, cement, brake and clutch.
Sound insulation, sheet plastic, etc. However, due to the realized effects of
asbestos. Global asbestos production volumes decreased. (However, the amount of
use of asbestos is still a lot), some countries such as New Zealand, Chile,
Finland, Japan, Italy and others, prohibit the use of asbestos. In Thailand
Amosite and chrysotile ore is allowed only in the industry, including the
Commission on Labels (No. 27) Act 2552 specifies that products containing
asbestos as a product ingredient label control. Require warning labels The
recommendations on the use of such products. It also presented a plan to cancel
the import, production and distribution of asbestos in the United States. The
Ministry of Industry In July 2556, but the plan is still under consideration in
the Cabinet imports.
Asbestos do with our bodies.
When rock or products
containing asbestos caused the cracks or damage. Asbestos being released into
the air. Then enter the respiratory system. People who work in industries that
have used asbestos. Are at high risk of getting asbestos. A survey of asbestos
in the air of industrial types (pipe, cement roof tiles, vinyl flooring. Color
and acrylic paint on. Brake and clutch) number 20 of the year in Thailand from
2530 to 2531 found that manufacturing brake and clutch have the highest amount
of asbestos in the air. In addition, family members of people who work in the
industry with respect to asbestos, it is entitled to asbestos-contaminated
clothing, shoes, skin and hair of those who work it.
Asbestos was inhaled To the
left lung To get asbestos multiple times to generate free radicals. And the
inflammatory process Cause asbestosis, lung disorders such as pulmonary
fibrosis, which means from inhaling asbestos. In addition, asbestos is also
toxic to the cell's genetic system. The study of the various departments.
Confirmed that asbestos is carcinogenic to humans. The asbestos was associated
with lung cancer risk. Cancer lining of the chest and abdomen. (Mesothelioma)
and cancer of the gastrointestinal tract. Factors that affect the risk of
disease from inhaling asbestos are.
1. The quantity of
asbestos inhaled. The disorders in the body are correlated with the amount of
asbestos asbestos.
2. Time to get asbestos.
Inhalation of asbestos since the first period to the present. (Without regard
to whether asbestos is present to receive or not) diseases caused by asbestos,
it takes a relatively long time (10 to 40 years) than the disease.
3. The size, shape and
chemical composition of asbestos. Asbestos that is longer than 20 microns are
related to asbestosis crocidolite asbestos inhalation can cause a risk of lung
cancer than chrysotile asbestos to tenfold in some cases. (Less than 0.4
microns wide and less than 0.2 microns) on the subject of chemical elements
that are crociolite iron content than chrysotile may cause lung damage was
over.
4. Sources have asbestos
5. Each individual
factors such as smoking, which found that smoking increases the risk to the
dangers of asbestos.
How to prevent the dangers of asbestos.
Assigned to its control label
products that contain asbestos, so the consumer to use any product. That may
have asbestos components such as roof tiles. Floor tiles etc. Always read the
label that the product contains asbestos or not. In case of such products
containing asbestos. Follow a strict warning as to avoid demolition of such
products. Due to the release of asbestos into the air causing asbestos In
addition to the cement industry. People should avoid areas that are cut into
the building. Those who work in industries related to asbestos should shower
and change clothes before going home. To prevent the removal of asbestos to be
deposited in the house.
