There are many different products containing asbestos fibres, of which some are considered more dangerous than others. Learn more about the different asbestos containing products (ACMs) below, how to spot them and their degree of friability.

Types of Asbestos Fibres
Asbestos is predominately found commercially in three different forms, Crocidolite, Amosite and Chrysotile. Other types (Tremolite, Anthophyllite and Actinolite) are also found, but are more rare and usually only found as contaminants in other asbestos containing materials.
Chrysotile was the most commonly used form of asbestos in the construction industry and is often referred to as ‘white’ asbestos. Chrysotile in it’s pure mineral form does indeed have white fibres, but does not make identifying the presence of the material easy as it is often mixed with other materials to manufacture the finished product. Chrysotile was the only type of asbestos allowed in the UK from 1985 before its final ban in 1999.
Amosite, often referred to as ‘brown’ asbestos was widely used in the UK for producing insulation boards along with thermal insulation, pipes, slabs and moulded pipe fitting covers. Amosite is from the family of minerals known as Amphibole because of its harsh and spiky fibres. Amosite is considered one of the more dangerous types of asbestos due to the straight nature of the fibres.
Crocidolite, also known as ‘blue’ asbestos is also part of the Amphibole family of minerals like Amosite. Considered the most dangerous type of commercially used asbestos, its use in the UK reduced considerably in the 1960’s and 70’s as health concerns were raised. Crocidolite was used in various types of asbestos containing materials, but particularly apparent in sprayed coatings due to its high bulk volume.
