Introduction
Under regulation (EC) No 1272/2008 (the CLP regulation) of the European Union, asbestos is classified
as a carcinogen of group 1A [EC 1272/2008]. The REACH Regulation (EC) No. 1907/2006 prohibits the
placing on the market and use of asbestos fibres and of articles containing these fibres added intentionally
[EC 1907/2006]. Asbestos was banned in the 1990s at the international level in several European
countries and, since 2005, it has been completely banned within the European Union. Asbestos was used
in very large quantities for decades and was incorporated into many construction products which were
used in the construction of buildings and structures, as well as in industrial applications. Depending on
the country, buildings and structures constructed before 2005 may contain a variety of asbestos-
containing materials that still may pose a risk to building occupants and persons involved in construction
and demolition work [1999/77/EC].
Asbestos is a generic term encompassing six hydrated silicates with fibrous morphology comprising
chrysotile, amosite, crocidolite, anthophyllite, tremolite and actinolite, which are regulated by the
European Union through the REACH Regulation [EC 1907/2006]. Chrysotile, amosite, crocidolite or
anthophyllite were the asbestos types which were intentionally added in the past to construction
products. Chrysotile accounted for approximately 95 % of commercial asbestos consumption, and
amosite and crocidolite accounted for almost all of the remaining asbestos use. Tremolite asbestos and
actinolite asbestos were not extensively used commercially, however can appear as natural contaminants
in construction products (see ISO 22262-1).
Although the EU has now prohibited all asbestos use, there are several situations, however, which require
special attention to avoid “new construction products” which may contain asbestos being distributed in
the EU market. Several non-EU countries (primarily the Russian Federation, Kazakhstan, and China) still
mine and export asbestos and asbestos-containing products. Consequently, asbestos-containing products
manufactured in those countries and other countries where the importation of asbestos has not been
prohibited may enter the European market illegally. Naturally occurring asbestos (NOAs), which are not
technically enriched and processed, may be present as impurities in mineral raw materials, which are
used to manufacture new construction products. Even though European countries implement strict
quality control systems to prevent materials containing asbestos from re-entering new construction
products in the course of waste recycling [Cinderela, 2021], asbestos contamination may be found in
some cases. If a comprehensive asbestos survey and the consequent removal of all asbestos is not
conducted prior to demolition of a building or structure from the critical construction period (depending
on the country up to 2005), asbestos-containing materials (ACMs) may be present in the resulting
construction and dem
