Asbestos Information
Products containing asbestos have, until recent years, been widely
used in domestic construction and the mere presence of asbestos
does not, in itself, necessarily constitute a health hazard. Removing
undamaged material may release more dust than leaving it in place
and it is only when asbestos materials are in a damaged or friable
condition, or during installation, modification, removal or demolition,
that there is likely to be a significant health risk.
What is asbestos?
Asbestos is a naturally occurring mineral fibre used as a binder
to provide rigidity for other materials such as cement. It is also
fire resistant and was therefore was added to a variety of products
to strengthen them and to provide heat insulation and fire resistance.
Asbestos comes in several different types, some of which are more
dangerous than others. However, all types of asbestos are considered
dangerous if the fibres are inhaled, as they can cause lung cancers.
The risk of cancer increases with the number of fibres inhaled.
The symptoms of these diseases do not usually appear until about
20 to 30 years after the first exposure to asbestos.
Most people exposed to small amounts of asbestos, as we all are
in our daily lives, do not develop these health problems. However,
if disturbed, asbestos containing material may release asbestos
fibres, which can be inhaled into the lungs.
Asbestos material that would crumble easily if handled, or that
has been sawed, scraped, or sanded into a powder, is more likely
to create a health hazard. Fibre release is therefore most likely
if, for example, asbestos containing material is drilled into or
sanded - inadvertently releasing the fibres into the atmosphere.
How is the law going to change?
The law change largely concerns properties in commercial use.
This does not mean owner-occupied homes but the law does cover
common areas in flats and homes under housing association control.
These more explicit laws regarding asbestos replace those which
have been in force for some time.
The main change is the requirement for an inspection for the presence
of asbestos or asbestos containing materials (ACM's) in all commercial
properties. This is required so that any asbestos that is present
can have its condition monitored. The inspection will also prevent
work being carried out unknowingly on an ACM.
What should be done about asbestos in the home?
If you think asbestos may be in your home, don't panic! Usually
the best thing is to leave asbestos material that is in good condition
alone.
Generally, material in good condition will not release asbestos fibres. There
is no danger unless fibres are released and inhaled into the lungs.
Check material regularly if you suspect it may contain asbestos.
Don't touch it, but look for signs of wear or damage such as tears,
abrasions, or water damage. Damaged material may release asbestos
fibres. This is particularly true if you often disturb it by hitting,
rubbing, or handling it, or if it is exposed to extreme vibration
or air flow.
