General Information
The three
main types of asbestos used commercially are:
1. Crocidolite (blue asbestos); Amphibole
group. Banned 1992
2. Amosite (brown asbestos); Amphibole
group. Banned 1992
3. Chrysotile (white asbestos). Serpentine
group. Banned 1999
Other
amphiboles often manifest themselves as contaminants.
Fibrous
Actinolite, Fibrous Tremolite and Fibrous Anthrophyllite.
Asbestos
has been widely used in the UK since the turn of the last century. For example, it used to lag railway
carriages, pipework and boilers, in addition it was used in a variety of building
insulation and household products in the UK. Some 6 million tonnes of asbestos materials have been
imported into the UK since 1880, of which around 4.4 million tonnes have
been used in building products such as roofing, cladding, thermal insulation
and fire-resistant internal panelling.
Asbestos
fibres have excellent resilience and insulating properties and as such it
was used to make acoustic ceiling tiles and wall boards. It is found in many other building
materials including decorative coatings such as artex and vinyl floor
tiles. Due to its versatility it
could be applied or utilised by spraying, hand moulding, in preformed
sections or bound with other materials such as in asbestos cement.
Although
much of this asbestos-containing material has been removed over the years
there are many thousands of tonnes of asbestos still present in buildings. It is
estimated that over one and a half million workplace properties currently
have some form of asbestos in them.
Applications Why is it Dangerous? Asbestos related illnesses.
