There are two common ways of exposure to asbestos used in construction products. First, there is occupational exposure which may occur when you actively take part in construction projects with asbestos-based products. Secondary exposure then follows when you come into contact with a fellow worker who has been exposed to asbestos and carries the fibres on their hair, clothes or skin. Either way, you are at risk of developing Pleural Mesothelioma anytime you are exposed to the various types of asbestos based products used in construction. Here are two asbestos types putting at risk of developing this condition: 

Amphibole Asbestos 

Amphibole is an asbestos type that includes five minerals of asbestos. These are crocidolite, actinolite, anthophyllite and tremolite. Crocidolite is popularly referred to as blue asbestos. Generally, amphibole is made up of thin, brittle rod-shaped fibres. The brittleness means that amphibole breaks down quite easily into small particles, putting you at a higher risk of ingestion or inhalation. Small fibres can float I the air in large volumes unlike those that have a hard time disintegrating. 

Amphibole often occurs in form of friable asbestos because of how easy it can dislodge from construction products. However, its nature makes it rare in commercial products but it is common in natural stones and soils. The risk of exposure is high during excavations.

Serpentine Asbestos 

Serpentine asbestos is different from amphibole asbestos. It only comprises one mineral commonly referred to as white asbestos or chrysotile. Generally, serpentine asbestos has long and curly fibres, which are ideal for use in commercial construction products. It's excellent for adding heat resistance and fire proofing attributes to construction products. 

The risk of exposure occurs when carrying out actual construction or demolition of structures built using serpentine-based products. Even though the fibres are big and quite rigid, forceful fragmentation of structures disintegrates and allow them to float in the air

The Bottomline

Whether you are exposed to amphibole or serpentine, the risk of Pleural Mesothelioma remains high. This condition leads to the growth of cancerous cells in the pleural membrane of the lungs. The rate of growth of the cells varies but a higher level of exposures hastens the growth of the cells. More importantly, amphibole asbestos is more hazardous because the small nature of the fibres makes it easy to inhale a large volume. To be safe, always make sure that asbestos based-products are safely removed or handled by professionals on the site.
