Asbestos is a fibrous mineral that has long been used in industry and construction due to its physical and chemical properties. Despite its ban since 2002 in many countries such as Spain, asbestos is still present in old buildings. Many people wonder what is asbestos in a house and what are the risks associated with this material. As this is a very relevant topic, in this article we will tell you everything you need to know about this mineral, how to identify it in your home, its types, dangers, and the steps to follow if you find it.
What is asbestos in a house?
Asbestos, also known as asbestos, was a material widely used between 1920 and 2000 in construction in homes and buildings due to its resistance to heat, fire, and mechanical stress.
It is commonly found in products such as vinyl flooring, pipes, ceilings and roofs, among others. Exposure to asbestos fibers is dangerous when the material degrades or is handled incorrectly, releasing microscopic particles into the environment that can be inhaled or ingested. These fibers can cause serious respiratory diseases that often manifest years after exposure.
If you find asbestos while doing any type of renovation in your home, it is essential to seek professional help to manage it, since its handling requires specific equipment and protocols to avoid releasing its fibers into the environment.
types of asbestos
There are different types of asbestos, each with different physical characteristics and specific applications in construction.
- Chrysotile (White Asbestos): This is the most common and widely used type of asbestos. It is found in ceiling, wall and floor panels. Its use has also extended to car brakes, pipes and boiler seals. Despite being the most widely used, it is still highly dangerous in large quantities or when its fibres are inhaled over a long period.
- Amosite (Brown Asbestos): Common in insulation boards, cement boards and insulation products, it is one of the most dangerous types due to the shape of its fibers which tend to stay in the lungs if inhaled.
- Crocidolite (Blue asbestos): It was used in protective fabrics, steam engine insulation and cement products. It is highly toxic and breaks down very easily, releasing dangerous fibres.
- Anthophyllite: Rarer than the previous ones, it can be found in insulating products and construction materials, as well as a contaminant in products such as talc.
- Tremolite and Actinolite: Rarely used commercially, but present as contaminants in other products containing asbestos, their danger lies in their ability to release toxic fibres once manipulated or damaged.
What to do if you find asbestos in a house?
If you discover the presence of asbestos in your home, the first thing to keep in mind is not to handle it without the proper equipment. Asbestos does not pose a danger if it is in good condition and is not handled, but if it is damaged, it can release its fibers into the environment. Here are some general guidelines to follow:
- Consult an expert: Asbestos removal must be carried out by trained personnel with specialized equipment. These experts are trained to minimize risks during removal.
- Sealing and proper handling: All asbestos items must be removed and sealed in hermetically sealed bags to prevent the release of particles into the environment and then transported to an authorized landfill.
- Avoid any type of intervention: Do not cut, scrape or break any asbestos-containing structures, as this could irreversibly release fibres into the air.
- Replace material: It is advisable to replace any structure containing asbestos with less polluting materials, such as asbestos-free fibre cement, synthetic and natural fibres.
Common areas with asbestos in a house
Asbestos is commonly found in pipes, roofs and water tanks, but it can also be hidden in other places. Below are the key locations where asbestos is commonly found:
- ceilings: frequently on uralite roofs, a type of corrugated fibre cement with asbestos.
- Pipelines: Insulation of heating pipes, hot water or air conditioning systems, especially in older buildings.
- Panels and cladding: You may find asbestos in fiber cement walls and interior cladding.
- Downpipes or drains: frequently used in water evacuation systems of buildings built before 2002.
Diseases related to asbestos exposure
Long-term exposure to asbestos has been linked to a wide range of diseases, many of them fatal. Scientific studies show that exposure can lead to:
- Mesothelioma: Cancer directly linked to asbestos that mainly affects the pulmonary membranes.
- Asbestosis: Chronic lung disease that causes scarring of the lungs, making breathing difficult.
- Lung cancer: Exposure to asbestos fibres significantly increases the risk of developing lung cancer, especially in smokers.
- Pleural plaques: Fibrous buildup in the lungs that can affect their function.
- Chronic respiratory diseases: Some people may develop symptoms more than 20 years after initial exposure.
How to identify asbestos in a house?
Identifying asbestos in a home is not an easy task, as it is not visible to the naked eye unless it is labelled. Furthermore, as it was such a common material in construction until it was banned, it can be found in many areas of an older home.
Generally, the only reliable way to detect the presence of asbestos is to send a sample to a specialized laboratory. However, if you think you may be at risk, it is advisable to contact a trained professional to carry out the identification and analysis.
Special care is advised with two types of asbestos materials:
- Friable asbestos: Materials that crumble easily by hand and tend to release fibers without mechanical intervention.
- Non-friable asbestos: It is usually found in harder products such as fibre cement boards. When left untouched, these materials are less dangerous.
All of this shows that exposure to asbestos can be a silent threat to health, and proper management of these materials in homes is crucial to avoid tragic long-term consequences.
Despite the dangers that asbestos poses, proper identification, management and replacement measures can minimize any risk. If we discover asbestos in our home, we should always turn to removal experts to ensure our safety and that of those around us.
