What is Asbestos?

What is Asbestos?

Asbestos is a naturally forming mineral, which was commercially mined for its useful properties such as:

 

  • Chemical resistance
  • Heat resistance
  • Low thermal conductivity
  • Flexibility
  • High tensile strength.

 

Health Effects

 

According to the Health & Safety Executive, asbestos is responsible for more workplace deaths each year than any other cause. Diseases caused by inhaling asbestos fibres include lung cancer and mesothelioma. There is often a latency period of up to 40 years before any symptoms are shown, so exposure may not be apparent until much later.

 

The import and use of asbestos has been banned since 1999 in the UK.

 

Asbestos Types

 

Read about common materials which can contain asbestos.

 

There are six types of asbestos which are banned from use in the UK;

 

Chrysotile

Also known as white asbestos. Chrysotile is cream, white or pale green in its raw state. Its soft curly fibres made it ideal for spinning and weaving, and it is alkali-resistant. Chrysotile is by far the most commonly mined and used type in the world.

 

Amosite

Also known as brown asbestos or fibrous grunerite. Amosite is brown or black when raw. Processed fibres appear to be grey or brown and are straight and needle-like. It is hydrophobic which made it useful in products which needed to dry quickly.

 

 

Crocidolite

Also known as blue asbestos or fibrous riebeckite. Crocidolite fibres are a distinctive blue and are flexible enough to be spun and woven like chrysotile. It has the highest tensile strength and is highly acid resistant. Crocidolite is considered to be the most harmful of the fibre types.

 

 

Other Asbestos Types

 

There are three other forms of asbestos which are banned in the UK. These are anthophyllite, tremolite and actinolite. These fibres are quite rare and were mostly used in bespoke applications because the fibres were too weak for most applications.

History

Asbestos has been used in fire resistance applications, such as crematoriums, for centuries but was first used in building and construction as far back as the late 1800’s. Extensive usage occurred within the construction of buildings, between the late 1940’s until the mid-1970’s. However, some asbestos products were still being installed in buildings as late as 1999.

 

The legislation is based on a new duty to manage asbestos, The Control of Asbestos Regulations 2012 (CAR2012). This new regulation gives specific guidance on who the duty holder is and their responsibilities. Principally the duty holder must find out the location and quantity of all asbestos materials in their building and the condition of that asbestos must also be assessed.
