Background Asbestos is an incombustible mineral fibre It used to be used extensively in construction products, primarily for its fire resistant properties The use of asbestos as a building material is now banned in the UK, but it remains in the structure of many buildings There are three main types of asbestos, all of which can be dangerous The type of asbestos present cannot be identified by its colour
Types of Asbestos Blue asbestos (crocidolite) Brown asbestos (amosite) White asbestos (chrysotile) White asbestos most commonly used
Health Risk Asbestos is only a risk to health if fibres are released into the air and breathed in Breathing in air containing asbestos fibres can lead to asbestos related diseases, mainly cancers of the lungs and chest lining The more asbestos fibres breathed in the greater the risk, although repeated low exposures may also lead to cancers There is usually a long delay between first exposure to asbestos and the onset of disease, varying from 15 to 60 years There are 4000 deaths a year in the UK related to asbestos exposure
Where is asbestos typically found? Sprayed asbestos and asbestos loose packing used as fire protection in buildings Moulded or preformed lagging used in thermal insulation of pipes and boilers Insulating boards used for fire protection, thermal insulation, partitioning and ducts Some ceiling tiles Asbestos cement products, which can be moulded into a wide range of shapes Bitumen roofing material Vinyl or thermoplastic floor tiles
Examples of materials that contain asbestos
Company responsibility Find out where asbestos containing materials are present and what condition they are in Presume materials contain asbestos unless there is strong evidence that they do not Keep an up to date record of the location and condition of asbestos containing materials Assess and manage the risk from the material Provide information to anyone who is liable to work on or disturb the material
Asbestos on Site A survey has been performed to define where asbestos is or could be present An up to date list of all asbestos on site is held in the asbestos register: Health and Safety\Data\Asbestos\Asbestos Survey
Work on site Check the asbestos register before perforating any structural material If there is a chance that the material to be perforated does contain asbestos, there are two options: Find a way of completing the work without disturbing the material Have a survey performed by a specialist contractor to define the material’s composition If the material is found to contain asbestos, only a specialist contractor may perform work on it
