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 distinction between these two families is based on the shape and structure of their fibres:
Amphibole asbestos fibres are straight, brittle, and needle-like, with colours ranging from green to blue to brown. This family includes amosite, crocidolite, tremolite, actinolite, and anthophyllite.
Serpentine asbestos fibres are long, curly, and flexible. Only one type falls into this family: chrysotile, which is often white in appearance.
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—Tremolite, Actinolite, and Anthophyllite—were usually present as contaminants in asbestos products, rather than being deliberately used. While rarely found in UK properties, these can still appear during comprehensive asbestos surveys.

Understanding these types is crucial, as their different fibre shapes and structures affect how easily they become airborne and how dangerous they are to human health.
What’s the Difference Between Friable and Nonfriable Asbestos?
When talking about asbestos-containing materials, you’ll often hear the terms “friable” and “nonfriable.” But what do these actually mean?
Friable asbestos
Friable asbestos refers to materials that can be easily crumbled, powdered, or reduced to dust by hand pressure. Think of ceiling tiles, loose insulation, or old pipe lagging—if you can crush it in your palm, it’s friable. This kind poses a much higher risk because disturbing it can release fibres directly into the air, allowing them to be inhaled.
Nonfriable asbestos
Nonfriable asbestos, on the other hand, is bound tightly within a solid matrix. It might be found in things like cement sheets, vinyl floor tiles, or roofing materials. As long as these products are intact and undisturbed, the fibres are effectively locked in place. The danger arises if you cut, drill, sand, or otherwise damage them, at which point fibres can be released.
Whether friable or nonfriable, asbestos-containing materials should never be handled without proper precautions. Professional inspection and testing by qualified experts is the safest route if you suspect asbestos in your property.
The Dangers of Asbestos
Asbestos is often referred to as a “hidden killer” because it causes diseases that develop over decades.
Key Facts About Asbestos-Related Diseases and Deaths
Asbestos exposure remains a significant public health concern, with its dangers enduring long after its widespread use ended. Here are some essential facts and figures to keep in mind:
- Strong Link to Cancer: Asbestos exposure is a direct cause of several cancers, including mesothelioma, lung cancer, laryngeal cancer, and ovarian cancer.
- Global Bans: More than 60 countries have completely banned asbestos use due to its health risks.
- Mesothelioma Statistics: Mesothelioma—an aggressive cancer almost always caused by asbestos—claimed over 2,200 lives in the UK in 2022, according to national health data.
- Other Asbestos-Related Deaths: Each year, thousands more deaths are attributed to asbestos-related lung cancer, with estimates exceeding 6,000 annually in some countries.
- Long-Term Illnesses: Diseases caused by asbestos often take decades to develop, meaning diagnosis is usually late and outcomes are often poor.
These sobering facts highlight why asbestos continues to be monitored and regulated worldwide.
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.
Why Did Companies Persist with Asbestos?
Despite growing evidence of the dangers associated with asbestos, many companies continued to use it for decades. Why? The answer lies in a mix of industrial demand and denial—even after early warning signs appeared.
Asbestos was seen as a “wonder material,” prized for its fire resistance, strength, and affordability. It became a staple in countless products, from building insulation and roof shingles to car brake pads and pipework. For builders, manufacturers, and regulators, it ticked almost every box: it was versatile, cheap, and everywhere.
However, as medical studies started to reveal links between asbestos exposure and serious illnesses like asbestosis and mesothelioma, businesses were slow to act. Some manufacturers even conducted their own research—and kept negative results under wraps. For years, they put profit ahead of worker safety, arguing that asbestos posed little risk if precautions were followed. Even as labor unions and advocates began to push back, the process of phasing out asbestos took decades.
It wasn’t until a combination of lawsuits, public awareness, and tighter government regulations forced their hand that widespread use began to wane. Tragically, this long delay meant that workers—and their families—were exposed for far too long, often with devastating consequences.
How Are People Exposed to Asbestos?
Most asbestos exposure occurs in the workplace, especially in industries such as power plants, factories, shipyards, chemical plants, steel and textile mills, and automotive repair shops. Workers in these settings can inadvertently bring asbestos fibres home on their clothing, potentially exposing their families as well.
But it’s not just workplaces at risk. Asbestos is also present in many homes, public buildings, and even the environment. People living near natural asbestos deposits or old industrial sites may encounter airborne fibres. Although asbestos use is now heavily regulated, many older buildings and some consumer products still contain asbestos, meaning exposure remains a concern today.
What Are Safer Alternatives to Asbestos?
With the dangers of asbestos now well understood, manufacturers have shifted to using safer materials that offer similar benefits without the health risks. These alternatives include:
- Polyurethane Foam: Commonly used for insulation due to its excellent thermal properties and light weight.
- Silica Fabric: Provides heat resistance for industrial settings, making it suitable for protective clothing and fire barriers.
- Cellulose Fiber: Derived from plant materials, this is often used in insulation and building products for its safety and effectiveness.
- Thermoset Plastic Flour: Used in electrical insulation and as a reinforcing agent in various products.
These materials are not only safer but also tend to be more cost-effective, making them a preferred choice across modern manufacturing and construction projects.
Occupations and Industries with the Highest Asbestos Exposure Risk
While asbestos can threaten anyone in the wrong place at the wrong time, some jobs have long placed workers directly in harm’s way. Historically, people working in mining, shipbuilding, construction, manufacturing, and the military faced some of the highest levels of asbestos exposure. These weren’t just dangerous day jobs—workers would often bring asbestos fibers home on clothing, unknowingly putting their families at risk as well.
Even today, certain professions still run into asbestos more frequently than most. If you work with automotive brakes and clutches, maintain old building materials, or take on renovation and demolition projects in vintage structures, the risks remain. Maintenance crews in factories, firefighters, and workers repairing older industrial equipment also have reason to be vigilant. Industries like chlor-alkali production and oilfield brake block repair are modern examples where exposure still occurs, despite increased safety regulations.
Some examples of historically and currently high-risk occupations include:
- Mining (especially asbestos mining)
- Shipbuilding and ship repair
- Construction and demolition
- Manufacturing (including textiles, cement, and insulation),
- Power plant and heavy industry workers,
- Firefighters,
- Automotive mechanics (brake and clutch repair),
- Chlor-alkali production,
- Maintenance of aged building materials and equipment
- Oilfield brake block repair
Regulatory changes have certainly improved worker safety since the mid-20th century. Still millions were exposed during the height of asbestos use from the 1940s through the late 1970s, and millions of workers in construction and industry remain at risk even today.
Early Signs and Symptoms of Asbestos Exposure
One of the most troubling aspects of asbestos exposure is that symptoms often remain silent for years—even decades. By the time you notice anything unusual, asbestos fibers may have already caused significant internal harm.
When symptoms first do appear, they tend to be subtle and easily mistaken for other common conditions, including:
- Persistent shortness of breath
- A lingering, dry cough
- Chest pain or tightness
- Unexplained fatigue
- Occasional pain or swelling in the abdomen (if the lining of the abdominal cavity is affected)
Because these early warning signs are so nonspecific, many people don’t connect them to asbestos exposure straight away. If you suspect past contact with asbestos and develop any of these symptoms, it’s crucial to speak with your doctor sooner rather than later. Early detection can sometimes improve outcomes.
What to Do If You’ve Been Exposed
If you suspect you’ve been exposed to asbestos—especially if you start to notice symptoms such as persistent cough, breathlessness, or chest pain—it’s important to consult your doctor promptly. Always mention your history of asbestos exposure during your appointment, no matter how long ago it occurred.
Be proactive: ask your healthcare provider about screening options for asbestos-related conditions, even if you feel fine. Early detection can make a significant difference. And if you receive a diagnosis like mesothelioma or another asbestos-related disease, seeking a second opinion from a medical specialist with experience in these conditions is strongly recommended.
Can Tests Show How Much Asbestos Is in Your Body or Predict Disease?
Medical tests can identify the presence of asbestos fibers in areas such as lung tissue, fluids, or even bodily waste. The most definitive method involves examining a lung tissue sample under a microscope. However, these tests have significant limitations. They cannot accurately measure how much asbestos remains in your body’s tissues, nor can they serve as a crystal ball to determine if—or when—you might develop an asbestos-related disease. In other words, while tests can confirm exposure, they cannot predict your individual risk or the likelihood of future health problems.
Secondary Exposure: How Families Can Be at Risk
While many people think of asbestos exposure as an occupational hazard, there’s an often overlooked risk—secondary, or “take-home,” exposure. Family members can encounter asbestos fibers when a worker unknowingly brings loose fibers home on clothing, shoes, or even skin and hair.
For example, a welder returning from a long shift, or an automotive mechanic finishing up a day at a local garage, may carry invisible asbestos dust on their work uniform. Simple activities like doing laundry, hugging a loved one, or sitting on the home sofa can then unknowingly spread these hazardous fibers to others in the household.
This means that spouses, children, and even roommates could be exposed without ever setting foot in a high-risk workplace. As history unfortunately shows us, secondary exposure has led to cases of asbestos-related diseases among family members decades after the fact.
Compensation Options for Asbestos-Related Diseases
For those facing an asbestos-related diagnosis, understanding your compensation options can offer a measure of relief during a difficult time. Thankfully, several avenues exist that can help cover the considerable costs associated with these illnesses.
Lawsuits and Settlements
Individuals who have developed mesothelioma or other asbestos-related diseases may pursue legal claims against manufacturers or employers responsible for their exposure. These lawsuits can provide financial compensation for medical expenses, lost wages, and other damages. Settlement amounts often range from thousands of pounds to millions, although actual figures vary based on the circumstances of each case.
Asbestos Trust Funds
Many companies that used asbestos have established trust funds as part of bankruptcy proceedings to compensate victims. If you qualify, filing a claim with one of these trusts can provide compensation without the need for a lengthy court case.
Claims for Secondary Exposure
Compensation isn’t limited to those who worked directly with asbestos. Family members and loved ones who became ill through secondhand exposure—such as washing contaminated work clothes—can also pursue claims.
Legal Assistance
Not all lawyers are created equal when it comes to asbestos cases. Seeking assistance from an attorney with experience in asbestos litigation is crucial. Specialized legal professionals can guide you through the complex process, ensuring that your claim is as strong as possible.
What Legal Actions and Lawsuits Have Been Filed by Those Affected by Asbestos Exposure?
Legal action has played a crucial role in supporting those impacted by asbestos-related diseases. Over the decades, thousands of people—including workers, residents, and families exposed indirectly—have pursued compensation through the courts.
Asbestos Lawsuits and Compensation
Victims of asbestos exposure (and their loved ones, in some cases) have filed lawsuits against manufacturers, employers, and suppliers who failed to protect them from known risks. These legal claims often seek compensation for:
- Medical expenses
- Lost income and future earnings
- Pain, suffering, and diminished quality of life
Many claims are resolved through settlements, which typically range from £800,000 to £1.5 million, though amounts can vary depending on individual circumstances and the severity of illness.
Asbestos Trust Funds
In instances where responsible companies have gone out of business, compensation may be available through asbestos trust funds. These funds were established specifically for those diagnosed with conditions like mesothelioma, asbestosis, or asbestos-related lung cancer.
Secondhand Exposure and Family Claims
Family members who have developed illnesses from secondary asbestos exposure—such as washing contaminated clothing—may also have grounds for legal action. UK law recognises these situations, allowing affected families to pursue claims.
Seeking Experienced Legal Help
If diagnosed with an asbestos-related disease, it is important to consult solicitors who specialise in asbestos litigation. These professionals can guide you through the claims process and ensure the strongest possible case. Ultimately, asbestos litigation holds industry players accountable for decades of neglect and cover-up—helping victims secure justice and vital financial support.
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.
Asbestos fibres have no taste or odour, making them impossible to detect without specialized equipment. Even trained professionals can’t confirm asbestos presence simply by looking at a material. This is why homeowners and property managers should never try to identify or handle suspected asbestos themselves—always consult a licensed asbestos professional to collect samples for lab testing.
Friable vs. Non-Friable Asbestos
- Friable asbestos materials can be easily crumbled or broken by hand. When disturbed, they release dangerous asbestos dust into the air, posing a serious inhalation risk.
- Non-friable asbestos materials have fibres locked into a solid matrix. These are generally safer if left undisturbed, but cutting, drilling, or breaking the material can still release hazardous fibres.
If you suspect a material may contain asbestos—especially in buildings constructed before 2000—do not attempt to disturb it. Always seek professional advice and testing to stay safe.
