Asbestos is a naturally occurring fibrous silicate mineral,
or put simply, asbestos is a fluffy rock! Every week 20 tradesmen die from
asbestos-related disease. If you carry out work on a building that was built or
refurbished before the year 2000, you could have been exposed to asbestos,
without even knowing it.
The three common types of asbestos are crocidolite, amosite
and chrysotile; although other forms can be found in premises – fibrous
actinolite, fibrous anthophyllite and fibrous tremolite.
Crocidolite, amosite and chrysotile are also known as blue,
brown and white asbestos, although the colour is not always significant in
identification.
Occasionally in publications there is a reference to the
mineral groups to which asbestos belongs. Chrysotile belongs to the serpentine
group (like fine threads of cotton) while the five other types listed above
belong to the amphibole group (like fine needles).

Health Risks
Every week 20 tradesmen die from asbestos-related disease.
If you carry out work on a building that was built or refurbished before the

Asbestos-related diseases kill more people than any other
single work related illness.
Asbestos-related diseases can take 15-60 years to develop
and there is no cure.
Asbestos-related diseases are currently responsible for
more than 4500 deaths a year in the UK and the number is still rising.
ACMs in good condition and left undisturbed cannot cause
ill-health.
The greater the disturbance of ACMs and the longer the
duration, the greater the risk to health.
History of Asbestos
The properties of asbestos have been known from ancient
times. This is not just that asbestos was fire proof, but that is was
dangerous. In Roman times it was known not to buy slaves from asbestos mines,
because although they might look healthy when bought, they did not live long.
Modern commercial history began in 1870 when a large deposit
was found in Canada.
Properties of asbestos that make it so useful are:
good thermal insulation
stable at high temperatures
good electrical insulation
high tensile strength
long flexible fibres; and
does not degrade over time.
As such, asbestos was widely used in buildings for
insulation and fire protection, e.g. roofing, cladding, thermal insulation,
etc.
Asbestos was very rarely used in its raw form in buildings
but was typically mixed with other products to make Asbestos Containing
Materials (ACMs). So, cement sheets with added asbestos became asbestos cement
sheets; insulating board with asbestos added became Asbestos Insulating Board
(AIB), and so on.
Much asbestos is still left in buildings, in the form of
ACMs and it is estimated about half a million non-domestic premises still
contain asbestos. When ACMs are not treated correctly, asbestos can be deadly!
