What is Asbestos? Types, Dangers, and Where It’s Found
Asbestos is a naturally occurring mineral made up of microscopic fibres. These fibres are often combined with other materials to produce asbestos-containing materials (ACMs). Asbestos was widely used due to its strength, heat resistance, and durability.
How Was Asbestos Used?
Asbestos was mined in countries like Canada, Russia, Brazil, South Africa, and China. The fibres were woven into fabrics or mixed into products used worldwide. In the UK, asbestos was predominantly used as a building material between the 1950s and 1980s. It provided:
- Insulation
- Fireproofing
- Soundproofing
- Waterproofing
- Chemical resistance
However, asbestos becomes dangerous when damaged or disturbed. The fibres can become airborne and inhaled, leading to serious health issues.
Types of Asbestos
Asbestos is classified into six mineral types within two families: serpentine and amphibole. The three most common types found in building work are:
Chrysotile (White Asbestos)
- Common Uses: Cement, linings, garage roofs, and floor tiles.
- Properties: Flexible, waterproof, and heat resistant.
- Risks: Most widely used and hazardous.
Amosite (Brown Asbestos)
- Common Uses: Cement sheets, pipe insulation, and insulating boards.
- Properties: Strong and heat resistant.
- Risks: Higher cancer risk due to coarse fibres.
Crocidolite (Blue Asbestos)
- Common Uses: Insulation and industrial materials.
- Properties: Thin, brittle fibres.
- Risks: Extremely harmful and easily inhaled.
Other less common types, such as Tremolite, Actinolite, and Anthophyllite, were usually contaminants in products. These are rarely found in UK properties but can still appear during asbestos surveys.
The Dangers of Asbestos
Asbestos is often referred to as a “hidden killer” because it causes diseases that develop over decades. These include:
Mesothelioma
A cancer affecting the lung lining, almost exclusively caused by asbestos exposure. Once diagnosed, it is typically fatal within months.
Asbestos-Related Lung Cancer
Similar to lung cancer caused by smoking, this type develops after prolonged asbestos exposure.
Asbestosis
A severe lung condition caused by heavy asbestos exposure over many years. It leads to scarring of the lungs, breathlessness, and, in severe cases, death.
Pleural Thickening
This condition causes the lining of the lung to thicken and swell, potentially leading to discomfort and restricted breathing.
Where is Asbestos Found?
Asbestos can be present in any building built or renovated before the year 2000. Common locations include:
- Insulation
- Cement sheets
- Floor and ceiling tiles
- Roofing materials
- Plumbing and boiler lagging
How Can You Identify Asbestos?
You cannot identify asbestos by sight, smell, or color. Its fibres are microscopic—10 times thinner than a human hair—and come in many forms. The only way to confirm asbestos is through testing or a professional asbestos survey.

Frequently Asked Questions
Q: What health risks are associated with asbestos exposure?
A: Exposure can cause mesothelioma, asbestos-related lung cancer, asbestosis, and pleural thickening. These diseases develop slowly and are often fatal.
Q: Where is asbestos commonly found in buildings?
A: Asbestos is often found in insulation, cement sheets, and roofing materials in buildings constructed before 2000. Testing is required to confirm its presence.
Q: What precautions should be taken during renovations?
A: Conduct an asbestos survey before renovations. Use trained professionals to handle asbestos safely, and follow all containment and disposal regulations.

Additionally, workers should use personal protective equipment (PPE) and follow strict safety protocols to minimize the risk of inhaling asbestos fibres.
