asbestos is a miracle mineral


Asbestos is a naturally-occurring fibrous mineral, known to Greeks as "miracle mineral" due to its durability, flexibility, and resistance to heat and chemical damages. Asbestos is composed of long and thin fibers that become airborne when damaged and disturbed. In the United States, the mineral is used in numerous industries and about 3,000 commercial products including: vinyl tiles, caulk, roofing and ceiling tiles, brakes shores, textiles, insulation, cement, and many more. It is used as fireproofing and insulating material in factories, schools, homes, and ships.
What are the Types of Cancer Caused by Asbestos?
Despite the many uses of asbestos, it is now considered as hazardous to public health. Studies have finally found out heavy and prolonged exposure to asbestos causes several serious illnesses to people.
Mesothelioma. This is a rare type of cancer that is almost exclusively caused by asbestos exposure. Even though the incidence rate has decreased in recent years, about 2,000 new cases of mesothelioma are diagnosed every year in the US.
There are three types of mesothelioma. Pleural mesothelioma develops in the lining of the lungs and considered as the most common. Peritoneal and pericardial esothelioma affect the membrane that surrounds the abdominal cavity and the heart, respectively.
The prognosis is poor because condition is often diagnosed in the advanced stages; mainly because symptoms are typically late to appear. There is no cure but different treatment options are available.
Lung Cancer. This disease is not directly linked to asbestos exposure; but the risk gets higher when combined with smoking.
Laryngeal Cancer. There is some evidence that links asbestos as cause of cancer of the larynx (or voice box).
Kidney Cancer. Many studies have shown that asbestos may also cause this type of cancer.
Other cancerous illnesses include: colon, intestinal, esophageal, and gallbladder.
Who is at Risk for Asbestos-Related Cancer?
People who are exposed to asbestos are holding high-risk occupations like: construction and demolition, shipbuilding and shipyard work, drywall removal and installation, auto brake repair, firefighting, and fireproofing.
Asbestos is not harmful when still whole and intact. When disturbed and damaged, it releases microscopic fibers into air. When inhaled or ingested by humans, these fibers get lodged in the tissues and cause inflammation that can lead to malignant tumor.

Asbestos dust clean

Mesothelioma is a disease characterized by scattered pulmonary fibrosis from the infiltration of asbestos dust into the lungs. Recent laws limit the usage of asbestos, but a lot of industries used it in the past. Hence, exposure occurred, and may still happen, in many jobs, comprising of manufacturing and mining of asbestos, shipbuilding, demolition of structures containing asbestos, and roofing. Further diseases connected to asbestos exposure include lung cancer, asbestosis, and asbestos pleural effusion.

The amount of exposure that leads to disease in people is up for debate. While there are numerous cases of factory or other workers that have had heavy exposure to free, friable exposure for several years developing disease, there are also cases where exposure has been as short as some months or only a few weeks. Intensity of exposure is most probable as relevant as length of time.

Dust of asbestos is a vicious thing. Due to the chemical structure of the material, the dust is like a cloud of fine glass particles. While they will not harm your skin, they do great harm to the lungs. Making matters worse, asbestos dust is so fine that it is simply raised from asbestos material like ceiling tiles and walls. Once in the air, it is all but unseen.

While you're performing a renovation project, below are a number of helpful tips to remove asbestos dust:
  • It's best to make use of hand tools to minimize the release of dust. Power tools are more probable to damage asbestos surfaces. 
  •  If you require to sand, make it wet sand. Dry sanding releases asbestos fibres into the air. 
  •  Moisten the asbestos material before working with it to reduce the danger of dust being released. Do not make use of a high-pressure jet. 
  •  Increasing some dish-washing liquid to the water you use will assist soak up asbestos particles. 
  •  Do not make use of an abrasive blasting system or any other high-pressure techniques to clean asbestos roofing, siding or cladding. Always make use of a low-pressure system. 
  •  Clean the area you have been working in completely. Dispose of any waste cautiously and in reference to your local laws.
