Asbestos fibres can nowadays be detected everywhere, even in the Antarctic.
In Spain, the use and marketing of asbestos has been definitively banned since 2002, but previously it was used in a large number of products for building and daily life such as cladding, corrugated Uralite roofing, sprayed plaster, air-conditioning and sanitation systems, flooring and many others.
In many of the products, the fibres are not released or are released very slowly. Other times the material is in a bad condition and the fibres are released continuously. The worst situations occur whenever drilling, scratching, breaking, sanding, etc. are used.
