What is Asbestos? | Usage, Risks And Safe Removal

Asbestos is a naturally occurring fibrous silicate substance. There are six different forms of it which are made up of elongated, fibrous tissue crystallites with many microscopic “fibrils” that can be exposed to the environment by erosion and other procedures. Asbestos is a good electrical insulator and has high thermal conductivity, hence it was utilized as a construction material for a long time. Asbestos, on the other hand, has become a well-known health and safety danger, and its use as a building material is now restricted in many nations. Asbestos fibers can cause several serious lung disorders, including asbestosis and cancer, when inhaled.
Despite the dangers of asbestos-related diseases, the product has been frequently utilized around the world, and asbestos is considered to be incorporated in most structures built before the 1980s. Many developing countries continue to encourage asbestos use as a building material, and asbestos mining continues, with leading producer Russia expecting to produce 790,000 tons in 2020.
Breathing is the most common way for asbestos fibers to penetrate the skin. Asbestos-containing material is only considered hazardous if it releases particles or fragments into the air, which can be ingested or swallowed. Many fibers will only become trapped in the mucosal membranes of the nose and throat, where they can be removed, but some of them travel deep into the lungs or into the digestive tract if eaten. The fibers might cause health problems once they are lodged in the body.
The most dangerous form of Asbestos is when it is friable. The term “friable” refers to the ease with which asbestos can be fragmented by hand and release fibers into the air. Asbestos insulation that has been sprayed is extremely brittle.
Ceiling tiles, floor tiles, undamaged laboratory cabinet tops, shingles, fire doors, siding shingles, and other materials that contain asbestos-containing will not release asbestos fibers unless it is damaged in some way. For example, if an asbestos ceiling tile is drilled or damaged, fibers may be released into the air. Damage and decay will make asbestos-containing materials more brittle. Water damage, constant vibration, aging, and physical impact such as drilling, grinding, polishing, cutting, sawing, or striking can break down the components, improving the probability of fiber to release.

Usage of Asbestos

Since the late 1800s, asbestos has been mined and utilized commercially throughout North America during World War II. Asbestos has been consumed in several sectors since then. The engineering and construction industries, for example, also using it to reinforce cement and polymers, as well as for soundproofing, waterproofing, and fireproofing.

Asbestos has been used to protect boilers, steam pipes, and warm water pipes in the shipping industry. Asbestos is used in automobile steering knuckles and clutch pads by the automotive industry. Ceiling and floor tiles, paints, varnishes, and adhesives, and plastics have all incorporated asbestos. It has also been discovered in vermiculite-based landscaping items as well as many talc-based crayons.

Asbestos Exposure Risks

Although no quantity of asbestos exposure is safe, the worst consequences occur when a person is exposed to a high concentration of it or is exposed to it frequently over a long period. With each exposure, asbestos builds up in the body, and there is no known method to undo the harm it causes.

The vast majority of asbestos-related disease patients are males in their 60s or older. This is due to the extended latency period of asbestos-related disorders, which can take decades to manifest. They are frequently linked to occupational exposure in traditionally male-dominated workplaces. Individuals who assisted in the rescue, restoration, and restoration efforts at the World Trade Center (WTC) in New York City on September 11, 2001, are also at risk of getting an asbestos-related disease. Because asbestos was used for the construction of the North Tower of the WTC, thousands of tons of asbestos were released into the environment when the building was demolished. Firefighters, police officers, paramedics, construction workers, and volunteers who toiled in the rubble at Ground Zero are the most vulnerable. Residents living near the WTC buildings and students who attended neighboring schools are among those who are at risk. To ascertain the long-term health effects of their exposure, these people will need to be followed upon. It is crucial to note, however, that any symptoms these people are experiencing could be caused to waste components other than asbestos.

Factors that increase the risk of developing an asbestos-related disease

Several factors can influence how an individual reacts to asbestos exposure, including:
Dosage: how much the person came in contact with asbestos
Duration: the amount of time a person was exposed.
Asbestos fibers vary in size, shape, and chemical composition.
The exposure’s source
Individual risk factors include smoking and having a history of lung illness.

Even though all kinds of asbestos are dangerous, different types of asbestos fibers may pose varying health concerns.

Several studies, for example, imply that amphibole forms of asbestos are potentially more dangerous than chrysotile, particularly in terms of mesothelioma risk, because they are more likely to remain in the lungs for longer.

Asbestosis

Asbestosis is a dangerous, non-cancerous, chronic lung condition. Asbestos fibers inhaled irritate lung tissues, causing scarring. Shortness of breath and a dry crackling sound in the lungs while inhaling are signs of asbestosis. The condition can progress to the point where it causes heart failure. Asbestosis has no effective treatment; the disease is usually deadly or debilitating.

Those who do not work with asbestos face a low chance of developing asbestosis, and the disease is rarely induced by exposure in the home or family. Depending on the nature of the exposure and the safeguards are taken, those who remodel or demolish buildings that contain asbestos may be at serious risk.

Symptoms of asbestos-related diseases

It’s possible that individuals won’t show any symptoms for years after being exposed to asbestos. People who develop asbestos-related illnesses may be symptom-free for up to 40 years after being exposed to the material. One must consult a doctor in case of the following symptoms:

Breathing problems.
Changes in cough patterns or the onset of a cough.
Blood coughed up from the lungs in the fluid (sputum).
Aches and pains in the chest and abdomen.
Swallowing difficulties or persistent hoarseness.
Drastic weight loss is observed.
Swelling of the neck or face.
Food loss is common.
Fatigue.

Effects of Smoking

The combination of smoking and asbestos exposure has been demonstrated in numerous studies to be highly dangerous. Smokers who are also exposed to asbestos have a higher risk of lung cancer than those who are exposed to both asbestos and smoking separately. Quitting smoking has been shown to lessen the incidence of lung cancer in asbestos-exposed employees.

Smoking does not appear to raise the risk of mesothelioma when paired with asbestos exposure. People who have been exposed to asbestos on the job at any point in their lives, or who believe they have been exposed, should not smoke.

Mesothelioma

Mesothelioma is a malignancy that arises from the thin layer of tissue that surrounds several internal organs (known as the mesothelium). The lining of the lungs and the chest wall is the most commonly affected areas. The lining of the abdomen, as well as the sac enclosing the heart and the sac enclosing the testis, are less usually harmed.

Shortness of breath owing to the fluid surrounding the lung, a swollen abdomen, chest wall pain, cough, fatigue, and weight loss are all signs and symptoms of mesothelioma. These signs and symptoms usually appear gradually.

Asbestos exposure is responsible for more than 80% of mesothelioma cases. The higher the danger, the larger the exposure. As of 2013, around 125 million people had been exposed to asbestos at work around the world. People who mine asbestos, make asbestos goods, work with asbestos goods, live with asbestos workers, or work in buildings containing asbestos have a higher risk of disease.

The time between exposure to asbestos and the beginning of cancer is usually around 40 years. When someone who has dealt with asbestos washes their clothes, they are putting themselves at risk. Genetics and infection with the simian virus 40 are two more risk factors. The diagnosis may be anticipated based on the findings of chest X-rays and CT scans, and it is confirmed by studying cancer’s fluid or performing a tissue specimen.
