(Almost) Everything You Need to Know About Asbestos:

 

What is Asbestos?

Asbestos is a naturally occurring mineral that is found in rock formations all around the world. It is typically mined from underground deposits, and the largest deposits are found in countries such as Russia, China, Canada, Brazil, and Kazakhstan.

Asbestos is formed from the metamorphism of serpentine and amphibole minerals, which can occur when rocks are subjected to intense heat and pressure. This process can create fibers that are long, thin, and durable, which is what makes asbestos so useful in construction materials and other products.

Asbestos can be found in many different types of rocks and soils, including serpentine rock, which is the source of chrysotile asbestos, and amphibole rock, which is the source of several other types of asbestos, including amosite, crocidolite, tremolite, anthophyllite, and actinolite. However, not all rocks and soils that contain asbestos are suitable for mining, and the quality and quantity of asbestos in these deposits can vary widely. Chrysotile, also known as white asbestos, was the most commonly used type of asbestos, and accounts for about 95% of asbestos used in the United States.

 

What was Asbestos used in?

Due to its heat resistance, durability, and other desirable properties, Asbestos was used in a host of products. Some of the common uses of asbestos include:

  • Insulation: Asbestos was commonly used in insulation products such as pipe insulation, attic insulation, and vermiculite insulation.
  • Roofing and siding: Asbestos was used in roofing and siding products such as shingles, tiles, and cement sheets.
  • Flooring: Asbestos was used in vinyl flooring, floor tiles, and backing materials.
  • Textiles: Asbestos was used in fire-resistant textiles such as blankets, gloves, and aprons.
  • Automotive parts: Asbestos was used in brake pads, clutch facings, and gaskets.
  • Electrical components: Asbestos was used in electrical insulation and wiring.
  • Other products: Asbestos was used in a wide range of other products, including cement pipes, fireproofing materials, and even cigarette filters.

 

When was Asbestos outlawed / banned?

The use of asbestos has been banned or restricted in many countries around the world due to the health risks associated with its exposure. The timing and extent of these bans and restrictions vary depending on the country and the type of asbestos.

In the United States, the use of asbestos in new products was largely phased out in the 1970s and 1980s, and the Environmental Protection Agency (EPA) issued a series of regulations in the late 1980s and early 1990s to further restrict its use. However, some uses of asbestos, such as in automotive parts and certain types of roofing materials, were not fully banned until the late 1990s.

In the European Union, a full ban on asbestos was implemented in 2005, although some exemptions were granted for certain uses until 2009. Many other countries, including Australia, Canada, Japan, and Brazil, have also implemented bans or restrictions on the use of asbestos in recent years.

 

What are the health problems that can be caused by Asbestos exposure?

Asbestos exposure can cause a variety of serious health problems, many of which do not become apparent until years or even decades after exposure. The health hazards of asbestos include:

  • Mesothelioma: Asbestos exposure is the leading cause of mesothelioma, a rare and aggressive form of cancer that affects the lining of the lungs, chest cavity, and other organs. Mesothelioma has a long latency period, and it can take 20 to 50 years or more after exposure for symptoms to develop.
  • Lung cancer: Asbestos exposure is also a significant risk factor for lung cancer. The risk of lung cancer is highest for individuals who are exposed to high levels of asbestos fibers over long periods of time, such as asbestos miners and insulation workers.
  • Asbestosis: Asbestosis is a chronic lung disease that occurs when asbestos fibers are inhaled and become lodged in the lungs, causing inflammation and scarring. Symptoms of asbestosis include shortness of breath, coughing, and chest pain, and it can lead to respiratory failure and other serious complications.
  • Pleural disease: Asbestos exposure can also cause pleural disease, which affects the lining of the lungs and can cause chest pain, shortness of breath, and other symptoms.
  • Other cancers: Asbestos exposure has also been linked to other cancers, including cancers of the larynx, ovaries, and stomach.

The health risks associated with asbestos exposure are serious, and there is no safe level of exposure to asbestos fibers. Therefore, it is important to take appropriate precautions when working with or around materials that may contain asbestos, and to seek medical attention if you believe you have been exposed to asbestos.

 

How do I know if a home has asbestos in it?

It can be difficult to determine if a home contains asbestos just by looking at it, as asbestos-containing materials may look similar to non-asbestos materials. However, if your home was built before the 1980s, it is more likely to contain asbestos, as asbestos was commonly used in building materials until its use was phased out in the 1980s.

If you suspect that your home may contain asbestos, you can have a professional asbestos inspector or abatement contractor perform an inspection to identify any asbestos-containing materials. The inspector may take samples of suspect materials and send them to a laboratory for analysis. It is important to hire a qualified professional with experience in asbestos inspections and abatement, as improper handling of asbestos-containing materials can release fibers into the air and pose a health risk.

Some common building materials that may contain asbestos include insulation, roofing materials, floor tiles, ceiling tiles, and cement products. However, it is important to note that many other materials may also contain asbestos, and it is not always easy to identify them without proper testing. If you are planning any renovations or repairs in an older home, it is important to take appropriate precautions and have the materials tested for asbestos before beginning any work.

It is important to note that in the State of Texas, Asbestos inspecting, testing and remediation / removal is a regulated, controlled and licensed industry and most home inspectors are not qualifed to perform these tasks, including myself (at time of writing, April 2023). Any inspector or professional you hire to test / inspect a home for asbestos should be licensed by the Texas Department of Licensing and Registration for that specific catagory.
