Question 1: I have a water tank made from asbestos
cement. Is it safe?
Answer: Even if fibres are being released into the water,
there is no evidence that exposure to asbestos In drinking water
has any adverse effect on health at all. The outer surface of the
tank is usually in a relatively inaccessible place and so should
remain in good condition. If access around the tank is needed at
frequent intervals then sealing the surface with a decorative or
other finish may be a sensible precaution.
Question 2: When asbestos is
found in buildings should it be removed?
Answer: It is recommended that if it is undamaged and
unlikely to be disturbed, material containing asbestos should be
left in place, if necessary sealing it in with paint, plastic or
UVA glue.
Question 3: I have heard that
inhaling one asbestos fibre kills. Is this true?
Answer: Asbestos fibres are present everywhere in the air
at very low levels. This means that everyone is breathing in a very
low level of fibres all the time. The small burden of fibres
resulting from this background exposure appears to be well
tolerated, so the theory that one asbestos fibre kills is
unfounded. Diseases caused by asbestos are work related. Plumbers,
builders, electricians, and central heating engineers are those
most at risk.
Question 4: What is the risk of
getting lung cancer from asbestos exposure?
Answer: The Department of Health statistics for deaths
from lung cancer in the UK are 7.2% in men, and 3.7% in women. The
extra risk from non-occupational exposure to asbestos is minuscule.
Question 5: Just how dangerous is asbestos?
Answer: Asbestos is a mineral substance that can split
into many tiny fibres. When present in the air, these fibres can be
inhaled into the lungs where they may lodge. If sufficient fibres
are inhaled they can lead to diseases such as asbestosis, lung
cancer and another type of cancer called mesothelioma. Crocidolite
(blue asbestos) and amosite (brown asbestos) pose a greater risk
than chrysotile (white asbestos), which is the most common type of
asbestos found in buildings. The exposures encountered by members
of the general public outdoors or in their homes are very low and
unlikely to present any risk. Nevertheless, it is wise to take
precautions if you are handling any substance you suspect may
contain asbestos.
Question 6: I am fairly sure I have white
asbestos in my home. How do I know whether it is pure chrysotile or
contaminated with the more dangerous kinds of asbestos (amphibole
Asbestos - crocidolite and amosite)?
Answer: This is a job for an expert - the material will
need to be analysed by a specialist firm. As a rule chrysotile was
used for most applications where some consumer contact was
expected, with amphiboles reserved for industrial applications, but
some amphibole (especially amosite) was used in buildings,
particularly those constructed in the 1950s.
Question 7: Are old asbestos
products more dangerous?
Answer: Not necessarily. In some cases (for example, asbestos
cement) the product containing fibres may deteriorate with age,
making fibre release more probable. Asbestos fibres are very
durable and their condition will not normally change over time.
There is no evidence that the overall risk associated with these
fibres will increase but exposure potential may be higher
with
Materials in poor condition due to age.
Question 8: Should all asbestos
products be removed from buildings?
Answer: It is recommended that, if it is undamaged and
unlikely to be disturbed, material containing asbestos should be
left in place, if necessary sealing it with paint or plastic film.
Question 9: I have an asbestos cement garage roof. What
precautions should I take when removing or repairing
it?
Answer: As this is outdoors there is unlikely to be any
risk of serious exposure to asbestos fibres.
However, asbestos cement sheets can be fragile so take care to
avoid falling through the roof. If you do decide to dismantle your
garage roof, the work should be carried out in accordance with HSE
guidance in Working with asbestos cement. If possible, spray the
sheets with water to reduce dust emissions. Try to remove them
whole and take care to avoid breakage or sliding dry sheets over
one another as this will release asbestos fibres into the air.
Avoid the use of power tools. A disposable dust mask that is 'CE'
marked to EN 149 with FFP2 particulate filters will provide an
additional level of protection. After removal, the asbestos should
be bagged or wrapped in polythene sheets, sealed, labelled
'Asbestos' and taken to a disposal site licensed to take asbestos
waste. Whole sheets of asbestos cement do not need to be sealed but
should be wrapped in polythene sheets. Information on disposal can
be obtained from your local authority.
Question 10: My ceiling has a
decorative coating (Artex, Pebblecoat and Wondertex used to contain
chrysotile asbestos). How should I remove it?
Answer: If possible, you should paint, cover or plaster over
the decorative coating rather than remove it. There are products on
the market for covering textured surfaces. Alternatively, if the
coating is applied to a plasterboard surface, the whole board may
be removed in pieces large enough for convenient handling and
disposal. If you do wish to remove the surface finish only, reduce
as much as possible the chance of you generating and inhaling any
dust by soaking the surface with warm water and scraping off wet.
Do not sand the decorative coating or scrape off dry. For best
protection while doing any minor DIY work you should wear a
disposable dust mask, 'CE' marked to EN 149 with FFP2 particulate
filters.
Question 11: The paint on my
asbestos soffit boards is flaking badly. What is the best way to
renovate and redecorate them?
Answer: Avoid working directly overhead. The existing
paintwork may be removed by carefully applying a proprietary paint
remover to the surface or by spraying with water and gently
scraping off loose material. A sealant and finishing coat should
then be applied. If sanding is absolutely unavoidable then a coarse
wet and dry paper USED WET will restore a finish. You should wear a
dust mask (as above) while doing this work. The area should be well
cleaned with a damp cloth when the job is complete and the cleaning
materials sealed in a plastic bag for disposal.
Question 12: How should I clean my asbestos cement
corrugated roof?
Answer: Do not clean the roof unless really necessary as
asbestos fibres may be released during the process. If cleaning is
necessary apply a moss killer (e.g Jeyes' fluid), using a brush or
spray, then remove the dead moss with a stiff broom a day or more
after treatment. Do not sand or scrape the cement. The use of
crawling boards should be employed when working on asbestos cement
roofs, as there is a risk of the boards breaking under pressure and
the worker falling through. HSE guidance 'Working with Asbestos
Cement' gives further directions.
Question13: I have asbestos
cement gutters that I want to remove. How should I do
this?
Answer: The procedure is basically the same as that for
asbestos cement roofing. Sections of guttering should be removed in
one piece wherever possible and any dusty material should be damped
down with water. Phone your local council for advice on disposal of
the waste.
Question 14: How should I dispose of the asbestos
materials that I have removed from my house?
Answer: Asbestos materials are treated as special waste,
and so cannot be disposed of in the same way as normal household
waste. Place the material in strong plastic bags (asbestos should
be double-bagged) and label clearly. Then transport to Wrentham tip
before 2pm. YOU WILL BE
CHARGED £30 A ¼ TON, £120 A TON TO DISPOSE OF THE ASBESTOS at
current tariffs (14/10/04)
Question 15: What is the danger
from asbestos released during fires? (eg Garages with asbestos
roofs)
Answer: There is no evidence of a risk to health due to
exposure to asbestos released during fires. This is mainly from
asbestos cement roofing materials and most of the fibres remain
sealed within the fragments. However, it is best to minimise
exposure to asbestos wherever possible, and so if it is suspected
that asbestos may be released during a fire, local residents should
stay indoors and should not pick up or otherwise disturb any debris
from the fire.
Question 16: What are the
dangers of living near land which is contaminated by
asbestos?
Answer: There is no reason to suppose that the
environmental levels of asbestos in the vicinity of contaminated
land will be significantly elevated.
Question 17: How can I find out if the house I am living
in contains asbestos?
Answer: This can be extremely difficult and tenants will
almost certainly need professional advice. The answer is that the
council are already surveying properties as part of their health
and safety programme. Your property will already be on the list of
properties to be surveyed if it is
suspected of containing asbestos. The age or construction method of
the property will have
indicated the priority of your property to be surveyed.
Not all properties will be surveyed at first for the presence of
asbestos.
Question 18: I live in a block
of council-owned flats where asbestos has been used in
construction. Whose responsibility is it to deal with the
asbestos?
Answer: The management of asbestos in any building is the
responsibility of the building owner, in this case the council.
Contact the council's housing department.
Question 19: What requirement
is there for landlords to inform tenants of the presence of
asbestos in a house?
Answer: There is no formal requirement on landlords to
inform tenants of the presence of asbestos or do anything about it
unless it is such that they should reasonably have been aware of it
and it is a real threat to the tenants' personal safety. The
Defective Premises Act 1972 puts a duty of care on the landlord to
take such care as is reasonable in all the circumstances to see
that tenants and other people are reasonably safe from personal
injury or disease caused by a defect in the property. The Landlord
and Tenant Act 1985 implies into all tenancies a condition that the
rented property is fit for human habitation at the start of the
tenancy and an undertaking that the
landlord will maintain that standard throughout the tenancy. A
property shall only be regarded
as unfit for human habitation if it is so defective that it is not
reasonably suitable for occupation.
Question 20: Can I get a grant
to have the asbestos removed from my home?
Answer: Grants are not generally available for the
removal of asbestos. Housing renovation grants are awarded by Local
Authorities, but all applications are means-tested and no
assistance can be guaranteed.
