The Asbestos Regulations also include the 'duty to manage asbestos’ in non-domestic premises. Guidance on the duty to manage asbestos can be found in the Approved Code of Practice The Management of Asbestos in Non-Domestic Premises, L127, ISBN 9780 7176 6209 8. There are a number of sets of regulations, which cover work with all types of asbestos-containing material; they place duties on duty holders, employers and the self employed. Most asbestos removal work must be undertaken by a licensed contractor but any decision on whether particular work is licensable is based on the risk. One should keep in mind the removal of the asbestos fibres where their thermal or acoustic properties are incidental to their main purpose may be used at high temperatures but have no insulation purposes.
