prescribes that each non-domestic building's "dutyholder", as defined in law, has a duty to manage the risk from asbestos and mandates that "a suitable and sufficient assessment is carried out". Risk assessment involves a combination of factors relating to the type and condition of the asbestos-containing materials and the likelihood of disturbance and exposure. Human exposure potential depends on the number of occupants in a building and the frequency and duration of use, and the nature of any disturbance: for example, intrusive maintenance activity within the building increases the risk of exposure - removing a number of asbestos-containing ceiling tiles to undertake works above the ceiling level would raise greater risks than changing a light bulb. Buildings may be ranked according to whether disturbance activity is undertaken: rare disturbance activity, e.g. a little-used store room low disturbance activity, e.g. office work periodic disturbance activity, e.g. industrial use or vehicular movement high disturbance activity, e.g. a fire door containing asbestos-insulating boards which is in constant use The HSE uses a priority scoring tool which combines assessment of the material containing asbestos and the disturbance risk. The outcome of the risk assessment will identify priorities for management of the locations and materials containing asbestos, for example areas which require urgent attention, materials which are not suited to any form of containment may need to be removed or encased, minor repairs may be needed, or labelling and provision of information may be sufficient to ensure that significant health risks can be avoided, e.g. for a little-used store room it may be sufficient to keep the door locked and attach a warning notice to the door. The HSE points out that "Regulation 4 is a duty to manage, not [just] a duty to survey". The removal of high-risk asbestos products from non-domestic properties is tightly controlled by the HSE and high-risk products such as thermal insulation must be removed under controlled conditions by licensed contractors. Further guidance on which products this applies to can be found on the HSE website along with a list of licensees. The current regulations show that it is a legal requirement that all who may come across asbestos in their day-to-day work have been provided with the relevant asbestos training. Bans The manufacture and import of Blue and Brown Asbestos were banned in the United Kingdom in 1985 by The asbestos (Prohibitions) Regulations 1985. The use of White Asbestos
