Updated: Aug 12

Some symptoms of asbestos exposure include persistent cough, shortness of breath, chest pain, and crackling sound when breathing. Long-term exposure can take years to develop but may lead to asbestosis, lung disease and cancer.

Symptoms of Asbestos Exposure


Symptoms of Asbestos exposure include:


  • Shortness of Breath Asbestos fibres can make breathing feel difficult or laboured. It might feel like you can't catch your breath easily.

  • Shortness of Breath Asbestos fibres can make breathing feel difficult or laboured. It might feel like you can't catch your breath easily.

  • Persistent Cough A cough that doesn't go away over time and may get worse.

  • Chest Pain or Tightness The chest may feel tight or painful, especially when taking deep breaths.

  • Crackling Sound While Breathing A crackling sound is heard when inhaling and exhaling.


Exposure to asbestos has significant health risks, primarily affecting the respiratory system. Symptoms may vary from shortness of breath and persistent coughs to more severe conditions like asbestosis and mesothelioma, which could surface decades after exposure.


These conditions highlight the importance of awareness and early detection, emphasizing the critical need for individuals who suspect asbestos exposure to seek medical advice and regular health monitoring.


 

Long Term Asbestos Related Diseases


  1. Asbestosis This is a lung disease that results from the inhalation of asbestos particles, leading to scarring of the lung tissue. Symptoms include severe shortness of breath and a persistent cough.

  2. Lung Cancer Asbestos exposure significantly increases the risk of developing lung cancer, especially among smokers.

  3. Mesothelioma This is a rare form of cancer that affects the lining of the lungs (and sometimes the lining of the abdominal cavity or heart) and is almost exclusively caused by asbestos exposure.

  4. Pleural Effusions This condition involves the build-up of fluid between the layers of tissue lining the lungs and chest cavity, leading to breathing difficulties.


It's important to note that symptoms of asbestos-related diseases can take a long time to appear after exposure, sometimes decades. Therefore, if you think you've been exposed to asbestos, it's crucial to inform your doctor and monitor your health for any signs of these conditions.


 

Life Expectancy of Someone with Asbestosis


Depending on the stage and severity of the asbestosis, the life expectancy of someone with this disease is 10.3 years on average.


The table below shows the 3 different stages of asbestos exposure and the average survival period after diagnoses.

Asbestosis Stage

Survival in Months (Years)

Stage 1

171 months (14.2 years)

Stage 2

50 months (4.1 years)

Stage 3

21 months (1.7 years)

Average life expectancy

124 months (10.3 years)


 

How Long Does Asbestos Stay in the Air?


In a quiet room with minimal air circulation, asbestos fibers can remain suspended in the air for as long as 48 to 72 hours. These fibers may settle on surfaces and can be reintroduced into the atmosphere when disturbed. Asbestos fibers are particularly insidious, as they can persist in the air for an extended period, presenting potential health hazards. Therefore, it is crucial to manage asbestos with caution and expertise to reduce its airborne presence and ensure proper cleanup.


How long these asbestos fibres stay floating around depends on a few things:


  • The Air Inside: If there's a lot of moving air, like from fans or open windows, the fibres might get blown around more and stay airborne longer.

  • The Room's Setup: In places with lots of nooks and crannies or soft furnishings, the fibres might settle down faster because they have more places to land.

  • The Asbestos Itself: Different types of asbestos fibres might float around longer than others because of their size and shape.


 

What Does Asbestos Smell like?


Asbestos doesn't have a smell. It's a naturally occurring mineral made up of tiny, fine fibres that are too small to see or smell.


Because you can't detect asbestos with your senses—it doesn't taste, smell, or look distinctive in its raw form—it makes it tricky to know when you're being exposed to it without proper testing. This is why asbestos is often discovered during building inspections or renovations when materials containing it are analysed by professionals.


The lack of a smell or any other immediate sensory indicator underlines the importance of being cautious and consulting experts when dealing with older buildings or materials that might contain asbestos.


 

What Does Asbestos look like Under a Microscope?


Imagine looking through a powerful magnifying glass that lets you see extremely small particles, like a piece of hair split into hundreds of pieces. Under a microscope, asbestos doesn't look like one single thing because it comes in different types, each with its own unique appearance. But, to make it easy to understand, let's talk about a common way many types of asbestos might look when magnified:


Asbestos under a microscope

Asbestos fibres are like very thin, tiny needles or threads. These fibres are so small that you can't see them with your eyes alone. They are bundled together like strands of hair that can be woven into a fabric or mixed into building materials to make them stronger.


Some types of asbestos might look more like curly, twisted fibres (imagine tiny, coiled springs or the curls of a woolly sheep), while others are straighter and needle-like. Under the microscope, these fibres can appear transparent or slightly coloured, depending on the type of asbestos and how the sample is prepared for viewing.


Because of these tiny, thin fibres, asbestos can easily break apart and become airborne, which is why it's considered dangerous when disturbed. The microscopic view of asbestos helps scientists and professionals understand how it behaves and why it's important to handle it with care to prevent inhaling these harmful fibres.


 

What does Asbestos Insulation look like?


Asbestos insulation, used in many homes and buildings until the late 20th century, can vary in appearance depending on its type and where it's used. However, here's a simple way to visualize what it often looks like:


asbestos insulation

  • Loose-fill Asbestos Insulation This type looks a bit like fluffy, loose cotton or wool. It can be found in attic spaces or inside walls. The fibres are small and can easily become airborne if disturbed.

  • Asbestos Sheet Insulation This form is more solid and was used to insulate pipes, boilers, and heaters. It wraps around these fixtures like a protective blanket and is usually a dull, greyish-white colour.

  • Vermiculite Insulation Although not all vermiculite contains asbestos, some of the vermiculite used for insulation before 1990 can be contaminated with asbestos. This type of insulation looks like small, pebble-like pieces that are shiny and might range in colour from grey to brown to silver-gold.

  • Spray-on Asbestos Insulation This appears as a rough, spray-applied coating on ceilings, walls, and beams. It's often found in industrial or commercial buildings.


Remember, it's tough to tell if insulation contains asbestos just by looking at it. If you suspect that your home or a building, you're in has asbestos insulation, it's essential not to touch or disturb it. Disturbing asbestos can release harmful fibres into the air. The best approach is to contact a professional who specializes in asbestos inspection and removal to safely handle the situation.
