Natural mineral

Asbestos is a natural mineral made up of thin fibers. It was widely used in building materials because it is strong, heat-resistant, and doesn’t burn. However, asbestos is dangerous when its fibers become airborne and are inhaled.

Breathing in these fibers can cause serious diseases such as lung cancer, asbestosis, and mesothelioma. Because of these health risks, asbestos use is now banned or strictly controlled in most countries.

Asbestos is dangerous because its tiny fibers can break apart and float in the air. When people breathe them in, the fibers can get stuck in the lungs and stay there for many years. Over time, this can cause serious health problems like lung cancer, asbestosis (lung scarring), and mesothelioma (a rare cancer).

The danger increases with long-term exposure or when old materials containing asbestos are damaged or disturbed.

Stats

Worldwide / Global

According to the World Health Organization (WHO): more than 200,000 deaths per year globally are estimated to result from occupational exposure to asbestos.
Some sources estimate up to ~255,000 deaths annually worldwide from asbestos-related diseases (including both occupational and non-occupational exposures).

For example, in 2021 it was estimated that there were ~216,535 deaths from asbestos-related thoracic cancers (including lung cancer and mesothelioma) globally..


By country / region examples

In the United Kingdom: Around 5,000 deaths per year from asbestos-related diseases (mesothelioma, lung cancer, asbestosis) were estimated.
In the Australia: It was reported that more than 4,000 Australians die annually from asbestos-related diseases. Daily Telegraph


Important caveats / notes

There is a long latency period: exposure to asbestos often causes disease many years (sometimes decades)

Many estimates focus only on occupational exposure (at work). Non-occupational exposures (e.g., in buildings, homes) add further deaths but are harder to quantify.

Because of differences in data collection, reporting, exposure history, and country regulation, exact numbers vary between sources.

Asbestos lungs

Asbestos lungs, also called asbestosis, is a chronic lung disease caused by breathing in asbestos fibers. Over time, these fibers can cause scarring (fibrosis) in the lungs, making it hard to breathe. Symptoms often develop many years after exposure and include shortness of breath, dry cough, chest pain, and tiredness.

Asbestosis is not cancer, but it increases the risk of developing lung cancer and mesothelioma. There is no cure, but treatment can help manage symptoms and slow the disease’s progress.

Countries Where Asbestos Removal Is Most Common

United Kingdom

Asbestos was banned in 1999. It is widespread in older homes and public buildings.

United States
No full ban, but many states have strict regulations. Large asbestos abatement industry due to older buildings.

Australia
Full ban since 2003; common in houses built between 1950–1990.

Canada
Banned in 2018; active national removal and awareness programs.

Sweden
Early ban (1982); strong regulations and certified asbestos removal companies.

Norway, Damnark
Similar to Sweden — early bans and regulated removal during renovations.

Germany
Banned in 1993; asbestos removal common in industrial and older residential buildings.

Japan
Full ban since 2012; large-scale removal in factories and offices.

Developing Countries
Asbestos use is still legal or only partly restricted in countries like India, Russia, China, and Brazil.

How to Be Safe from Asbestos

1. Identify asbestos before disturbing materials

Check if your home, workplace, or building materials contain asbestos, especially in buildings built before 1990.

2. Do not disturb asbestos-containing materials

Asbestos is dangerous when fibers become airborne. Avoid drilling, sanding, or breaking these materials.

3. Hire certified professionals

Only trained and licensed asbestos removal companies should handle removal or remediation.

4. Wear proper protective equipment

If you must be near asbestos, use a certified respirator, disposable gloves, and protective clothing.

5. Follow safe disposal rules

Asbestos waste must be sealed, labeled, and taken to approved disposal sites.

6. Regular inspections

For older buildings, schedule inspections to detect damaged asbestos before it becomes a risk.

7. Educate yourself

Learn about the locations of asbestos in your area and stay informed about regulations.

Air and Physical Samples of Asbestos

1. Air Sampling

Air sampling is used to detect asbestos fibers in the air, especially during or after renovation or demolition. It helps assess exposure risk. Samples are collected using a pump that pulls air through a filter, which is then analyzed in a laboratory under a microscope.

Types of air sampling

Personal sampling: Monitors the exposure of a worker wearing a sampling device.
Static sampling: Measures fiber concentration in a room or work area.


2. Physical / Material Sampling
Physical sampling involves taking a piece of suspected asbestos-containing material (ACM), such as insulation, ceiling tiles, or cement sheets, to confirm the presence of asbestos. Samples must be collected carefully to avoid releasing fibers.

Safety rules

Always wear protective clothing, gloves, and a respirator when collecting samples. Wetting the material can reduce fiber release.

Laboratory analysis

Samples are analyzed using methods such as Polarized Light Microscopy (PLM) or Transmission Electron Microscopy (TEM) to identify asbestos type and concentration.


3. When to Test

Before renovating or demolishing older buildings.
When air quality is suspected to be unsafe.
After accidental disturbance of materials.
