If you own, manage or have responsibilities for a workplace building that may contain asbestos, you need to think about the risk of exposure to workers and others who may use the building. You need to be able to identify, assess and manage any asbestos materials on your premises.
ASBESTOS - THE DANGERS
Asbestos is the greatest single cause of work-related deaths. Asbestos-related diseases (mesothelioma, asbestosis and lung cancer) are thought to kill up to 3,000 people each year, with these figures expected to rise until around 2010. These diseases take a long time to develop, which means that the people who are suffering and dying today were exposed to asbestos many years ago.
Huge amounts of asbestos were installed in buildings during the 1950s, 1960s and 1970s, and much of it is still in place today. Electricians, plumbers, building maintenance workers, shopfitters and carpenters may still be at risk when carrying out refurbishment, repairs etc. on buildings which contain asbestos. It is also now thought possible that repeated low level exposures, such as could occur during routine repair work, may also lead to asbestos induced cancers.
There is no cure for asbestos-related diseases. Blue (crocidolite) and brown (amosite) asbestos are known to be more hazardous than white (chrysotile). In general the more asbestos dust inhaled, the greater the risk to health.
WHAT LAW APPLIES?
The Control of Asbestos at Work Regulations 2002(CAWR)
These regulations lay down the practices that must be followed for all work with asbestos, including that which requires a licence. Employers must prevent the exposure of employees to asbestos or, where this is not reasonably practicable, reduce exposure to a level that is as low as possible. The Regulations also require the:
The Asbestos (Licensing) Regulations 1983
These regulations require work with the most dangerous types of asbestos - coating, insulation (lagging) and asbestos insulating board, to be carried out only by contractors who have a licence issued by the Health and Safety Executive.
‘Coatings’ includes fire protection mixtures, applied by spray or hand, and decorative and textured finishes.
‘Insulation’ includes lagging and infill, pre-formed sections of pipe insulation and millboards
‘Asbestos insulating board’ is a lightly compressed board made from asbestos fibre and hydrated Portland cement or calcium silicate with other filler materials and can be used for structural purposes e.g. as a partition.
Not included are:
Articles made of rubber, plastic, resin or bitumen, but which also contain asbestos, e.g. vinyl floor tiles, electric cables and roofing felts; other asbestos products which may be used at high temperature but have no insulation purposes such as gaskets, washers, ropes and seals and asbestos cement products.
Asbestos cement, normally found in the form of roofing sheets, wall boards, soffits, gutters, drainpipes and flues, is a mixture of cement and asbestos which in a dry state has a density greater than 1 tonne per cubic metre. If you are unable to distinguish whether material is asbestos cement or insulating board, you will have to have a sample analysed to determine its bulk density.
There are 3 exemptions from the requirement to hold a licence:
a)work of short duration;
b)air monitoring or sample collection to identify asbestos;
c)if you are an employer carrying out work with your own employees. You will, however, still have to formally notify your enforcing authority (under Reg.5) of the work to be carried out.
‘Work’ includes sealing or painting damaged asbestos insulating board or insulation or coating.
CAWR also still applies even to exempt work and work with asbestos cement, which means that the precautions outlined in CAWR must be taken and Maximum Exposure Levels also apply.
If you think that exemptions (a) and (c) apply, you should consult the enforcing authority for further advice.
Notification to Enforcing Authority
You must give the relevant enforcing authority 14 days written notice of your intention to carry out the work
The amended regulations also increase HSE's discretionary power to revoke a licence if the holder is found to be in breach of any health and safety legislation.

The Asbestos (Prohibitions) Regulations 1992 as amended.
These regulations prohibit the importation into the United Kingdom, and the supply and use within Great Britain, of amphibole asbestos - crocidolite (blue) asbestos and amosite (brown) asbestos, and, as amended in 1999, of chrysotile (white) asbestos. These regulations do not cover the supply and fitting of asbestos-containing vehicle brake linings. This is prohibited by separate regulations from the Department of the Environment, Transport and the Regions - The Road Vehicles (Brake Linings Safety) Regulations 1999
Proposed Duty to Manage Asbestos
WHERE IS ASBESTOS FOUND IN BUILDINGS?
In general, the materials that contain a high percentage of asbestos are more easily damaged and the above list is roughly in order of ease of fibre release.
Asbestos may be present if the building was constructed or refurbished between 1950 - 1980 and particularly if it also has a steel frame and/or boilers with thermal insulation. If present, you will need to know the location, form and condition of the material. You might need to arrange to analyse samples of materials that you suspect contain asbestos. Do not break or damage such material - samples should only be taken by suitably trained people (look for UKAS or NAMAS accredited companies under ‘Laboratories’ or ‘Analytical Research Chemists’ in Yellow Pages).
Assessing the condition of asbestos materials involves considering the risk of asbestos fibres being released into the air:
Deciding what to do depends on the condition and type of the material:
a)Good condition/not likely to be damaged/not likely to be worked on
>>>Safest to leave the material in place and introduce a management system.
For this to be effective the owner/occupier of the premises must be in a position to exercise control over access by workers, contractors etc. and be prepared to exercise that control.
b)Poor condition/likely to be damaged or disturbed
>>>Need to repair, seal, enclose or remove
Taking action offers a number of options:
Removal of Asbestos
Remember that work on asbestos insulation board, coating & lagging (including sealing & removal) must normally be done only by a contractor licensed by the HSE.
DISPOSAL OF ASBESTOS
Asbestos waste should be double-bagged in heavy-duty polythene bags and clearly labelled with the prescribed label before it is transported to an appropriately licensed disposal site.
The landfill site situated at Tuttle Hill in Nuneaton is licensed to receive asbestos waste.
WHAT YOU SHOULD TELL YOUR WORKERS/CONTRACTORS
Details about any asbestos materials (location, type etc.) and make them aware of any asbestos register. Referral of any enquiries etc should be to an appropriate nominated person identified in the management system.
Precautions to be taken if necessary i.e.
1)Never strip out asbestos insulation - the law requires a specialist contractor to do this to strict rules.
2)Where minor work on materials containing asbestos (e.g. asbestos cement) is to be carried out by workers/ contractors, make sure that they know they are working with asbestos and what precautions they should take e.g.
Always refer to current guidance or contact the Health and Safety Team for further advice.
