The three most common types of fibers are:
Chrysotile (white asbestos): A white curly fiber, chrysotile accounts for 90% of asbestos in products and is a member of the serpentine group. It is a magnesium silicate.
Amosite: Brown or gray, straight amosite fibers belong in the amphibole group, and contain iron and magnesium.
Crocidolite (Riebeckite): A member of the amphibole group, crocidolite takes the form of blue, straight fibers. It is a sodium iron magnesium silicate.
There are currently three sets of regulations that control exposure to asbestos:
The Control of Asbestos at Work Regulations 2002 (CAW), which govern the way all work with asbestos is done, to ensure it is done safely.
The Asbestos (Licensing) Regulations 1983 (ASLIC), as amended, which require work with all the more hazardous asbestos-containing materials to be done by a contractor licensed by HSE.
The Asbestos (Prohibitions) Regulations 1992 (Prohibitions Regulations), as amended, which ban the importation, supply and use of raw asbestos and asbestoscontaining materials.
