FOCUSWorking with asbestosMarch 2007 The International Labor Organization (ILO) publication entitled: Asbestos: the iron grip of latency highlighted the global damage done by asbestos. Dr. Jukka Takala, then Director of the ILO's SafeWork Programme and now Director of the European Agency for Safety and Health at Work, wrote: "Asbestos is one of the most if not the most important single factor causing work-related fatalities, and is increasingly seen as a major health policy challenge worldwide... asbestos is still the No. 1 carcinogen in the world of work." [1] In the UK asbestos is the single biggest cause of work-related deaths. Asbestos-related diseases such as mesothelioma, asbestosis and lung cancer are thought to be responsible for up to 3,000 deaths each year to past exposure. The UK Control of Asbestos Regulations S.I. 2006 No. 2739 came into force on 13 November 2006 except regulation 20 (4) except regulation which shall come in force on 6th April 2007. These Regulations bring together the three previous sets of Regulations covering the prohibition of asbestos, the control of asbestos at work and asbestos licensing. The Regulations prohibit the importation, supply and use of all forms of asbestos. They continue the ban introduced for blue and brown asbestos 1985 and for white asbestos in 1999. They also continue the ban the second-hand use of asbestos products such as asbestos cement sheets and asbestos boards and tiles; including panels which have been covered with paint or textured plaster containing asbestos. REMEMBER: The ban applies to new use of asbestos. If existing asbestos containing materials are in good condition, they may be left in place, their condition monitored and managed to ensure they are not disturbed. The UK 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 0 7176 6209 8 Regulation 4 of the Control of Asbestos Regulations 2006 shows how to manage asbestos in non-domestic premises. It explains the duties of building owners, tenants and anyone else with legal responsibilities for such premises. The regulation requires:
For those working in countries that do not have such regulations may find these UK ones useful and also the HSE's Asbestos micro web site www.hse.gov.uk/asbestos which gives details of other guidance and advice that is currently available. When working with asbestos or which may disturb asbestos is being carried out, the Asbestos Regulations require employers and the self-employed to prevent exposure to asbestos fibres. Where this is not reasonably practicable, they must make sure that exposure is kept as low as reasonably practicable by measures other than the use of respiratory protective equipment. The spread of asbestos must be prevented. The Regulations specify the work methods and controls that should be used to prevent exposure and spread. Worker exposure must be below the airborne exposure limit (Control Limit). The Asbestos Regulations have a single Control Limit for all types of asbestos of 0.1 fibres per cm³. A Control Limit is a maximum concentration of asbestos fibres in the air (averaged over any continuous 4 hour period) that must not be exceeded. In addition, short term exposures must be strictly controlled and worker exposure should not exceed 0.6 fibres per cm³ of air averaged over any continuous 10 minute period using respiratory protective equipment if exposure cannot be reduced sufficiently using other means. Respiratory protective equipment is an important part of the control regime but it must not be the sole measure used to reduce exposure and should only be used to supplement other measures. Work methods that control the release of fibres such as those detailed in the Asbestos Essentials task sheets for non-licensed work should be used. Respiratory protective equipment must be suitable, must fit properly and must ensure that worker exposure is reduced as low as is reasonably practicable. 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. Work is only exempt from licensing if:
Under the Asbestos Regulations, anyone carrying out work on asbestos insulation, asbestos coating or asbestos insulating board (AIB) needs a licence issued by HSE unless they meet one of the exemptions above. REMEMBER: Although you may not need a licence to carry out a particular job, you still need to comply with the rest of the requirements of the Asbestos Regulations. If the work is licensable you have a number of additional duties. You need to:
The Asbestos Regulations require any analysis of the concentration of asbestos in the air to be measured in accordance with the 1997 WHO recommended method. From 6 April 2007, a clearance certificate for re-occupation may only be issued by a body accredited to do so. At the moment, such accreditation can only be provided by the United Kingdom Accreditation Service (UKAS) You can find more details of how to undertake work with asbestos containing materials, the type of controls necessary, what training is required and analytical methods in the following HSE publications
