The history of asbestos in housing begins in the late 19th century when this mineral was recognized for its remarkable properties. Asbestos, known for its heat resistance, durability, and affordability, quickly found its way into various building materials used in homes. From insulation to roofing, flooring to siding, asbestos seemed like a miracle material capable of enhancing safety and longevity in construction. Its popularity peaked during the early to mid-20th century, becoming ubiquitous in residential buildings. In this blog, we will explore the historical background of asbestos use in residential construction, reasons for its popularity, its health risks, asbestos removal, and more. By reading this blog, you will gain insight into asbestos and learn about its safe removal to mitigate health hazards.
Historical Background of Asbestos Use
Asbestos has a long history and was prized for its remarkable properties. People have been using asbestos for hundreds of years to make things like pots, clothes, and insulation. However, it wasn’t used in construction materials for houses until the late 1800s. Its widespread use began during the Industrial Revolution in the 19th century, when people started utilizing asbestos widely in construction due to its fireproof nature and insulation capabilities. By the 20th century, asbestos was not only used in the construction materials of houses but also became widespread in various industries, from shipbuilding to automotive manufacturing. However, as research revealed the harmful effects of asbestos, governments worldwide started implementing stricter regulations on its use. As a result, many countries began phasing out its use in buildings and factories. Today, asbestos is heavily restricted in many countries, and its use has been significantly reduced.
Asbestos in Residential Construction
Asbestos in residential construction refers to the use of asbestos-containing materials (ACMs) in houses and apartment buildings. Asbestos is a mineral fibre that was widely used in construction due to its heat resistance, durability, and insulating properties. Insulation is a major area where asbestos was heavily utilized, particularly around pipes, boilers, ducts, and in attics. Flooring materials also frequently contained asbestos, such as vinyl floor tiles and the backing of vinyl sheet flooring. These materials were popular due to asbestos’s strength and resistance to wear and tear. Roofing materials are another category where asbestos was commonly used. Roof shingles and siding made of asbestos cement were prized for their durability and ability to withstand weathering. Ceilings, too, often contained asbestos in ceiling tiles and textured paints. These were applied for acoustic purposes or decorative finishes.
Reasons for Asbestos Popularity
-
Unique properties of asbestos
Asbestos is a mineral known for its exceptional heat resistance and durability. These properties made it highly desired after for various industrial applications, particularly in construction and manufacturing. Its ability to withstand high temperatures without burning or breaking down made it ideal for use in insulation, fireproofing, and even in textiles like protective clothing.
-
Economic factors
From an economic perspective, asbestos was attractive because it was relatively inexpensive to mine and process compared to alternative materials at that time. Its widespread availability meant it could be easily sourced and used in large quantities across industries. As a result, businesses found it cost-effective to incorporate asbestos into their products and building materials, driving its popularity further.
Health Risks and Decline in Use
-
Discovery of health risks
Asbestos poses serious health risks to humans. When asbestos materials are disturbed or damaged, tiny fibres are released into the air. If these fibres are inhaled or swallowed, they can become trapped in the body for a long time. Over years, this can lead to serious health problems such as lung cancer, mesothelioma (a rare cancer of the lining of the chest and abdominal cavity), and asbestosis (a chronic lung condition). The danger lies in the fact that these diseases may not show symptoms until many years after exposure.
-
Regulatory actions and decline in use
To protect public health, governments of different countries across world implemented regulations to minimize exposure to asbestos. This includes restrictions on its use in construction and manufacturing, and guidelines for safe removal and disposal of asbestos-containing materials. As a result, there has been a decline in the use of asbestos over time as safer alternatives are looked for and awareness of its health risks has grown among industries and the general public.
Asbestos in Existing Homes
-
Identifying asbestos in older homes
Identifying asbestos isn’t always easy because it’s often mixed with other materials. If your home was built before the 1980s, there’s a chance it contains asbestos. Asbestos can be found in various places in older homes and buildings. It’s commonly used in insulation, ceiling tiles, flooring, roofing etc. To know for sure if asbestos is present, you may need to have a professional inspect your home and take samples for testing in a specialized lab.
-
Risks of living with asbestos
Living in a home with asbestos isn’t immediately dangerous if the material is in good condition and left undisturbed. However, if the materials containing asbestos are damaged or deteriorate over time, they can release tiny asbestos fibres into the air. Breathing in these fibres over long periods can lead to serious health issues such as lung cancer, mesothelioma, and asbestosis.
Asbestos Removal and Management
At TYR Demolition, our role in asbestos removal is important for ensuring safe and compliant demolition projects. Asbestos, a hazardous material found in many older buildings, needs careful handling. Our primary responsibility at TYR Demolition is to safely identify, handle, and dispose of asbestos-containing materials during demolition projects. This involves thorough inspection of the site to locate any asbestos, followed by careful planning to ensure its safe removal. We follow process as below for asbestos removal:
- Initial Assessment: Before any demolition work begins, our experts conduct a detailed assessment to identify if asbestos is present and where it’s located.
- Safe Handling: If asbestos is found, our trained personnel use specialized equipment and techniques to carefully remove it without releasing harmful fibres into the air.
- Containment: Asbestos is securely contained to prevent any potential exposure. This may involve sealing off areas and using negative air pressure systems to control airflow.
- Disposal: Once removed, asbestos is safely packaged and transported to authorized disposal facilities that handle hazardous materials.
- Final Inspection: After removal, we conduct a thorough inspection to ensure all asbestos has been safely eliminated, and the area is safe for further work or redevelopment.
Conclusion
The use of asbestos in building homes is a story of both progress and unintended consequences. At first, asbestos seemed like a perfect solution for making homes safer and more durable. However, we’ve come to realize that it poses serious health risks. As we’ve become more aware of these dangers, there’s a growing urgency to handle asbestos safely, especially in older homes. Now, strict rules are in place to control how asbestos is used and disposed of, showing our commitment to keeping people safe. Looking ahead, it’s important to educate people about where asbestos might be in homes built before the 1980s. It is necessary to inspect with professional for identifying asbestos and its proper management. By doing this, we can protect everyone from the hidden risks of asbestos, ensuring that homes remain safe places for us and coming generations.
