Asbestos is a potentially hazardous mineral, which
if handled incorrectly can release fibres that can damage the
lungs. If sufficient fibres are breathed in, exposure to asbestos
fibres can cause lung disease (e.g. asbestosis and possibly
cancer). Therefore, the use and management of asbestos needs to
Asbestos has been used for many thermal and acoustic
insulation purposes in buildings and industry all over the world,
particularly from the 1950s to 1990s. In order to avoid
contamination of buildings and the environment, the management or
removal of asbestos requires specialist engineering controls and
careful planning to prevent pollution.
Survey and investigation are recommended for all
buildings more than ten to fifteen years old. Greater awareness
of asbestos toxicity since the 1980s has meant that the use of asbestos
is being phased out. Asbestos is no longer the material of choice
for most applications and controlled removal and decontamination has
been a statutory requirement in many jurisdictions. However,
requirements for abatement planning and operational management of
asbestos are not as well advanced in developing countries.
Asbestos is still present in many older buildings and has even been
required as a fire and acoustic insulation design feature in recent
years in some uninformed countries.
Asbestos management usually entails several
stages. Survey and investigation are the first step in which the
asbestos specialist will check all building structural elements,
fixtures and fittings for fibrous (potential asbestos materials).
Samples are taken under controlled conditions and an accredited
laboratory analyses the samples using polarises light microscopy.
The asbestos specialist will then assess the type, location and
condition of asbestos and make a hazard assessment. If the
asbestos carries a high risk, an asbestos abatement plan is usually
prepared to cover removal with detailed work specifications for
specialist contractors. If only low risk asbestos is found
operational management plans may be drawn up to enclose, encapsulate
and manage the asbestos in situ. Likewise these options may be
chosen for high risk materials which are too dangerous or difficult to
remove immediately. In all cases the asbestos should be labelled
and safety procedures instigated to prevent disturbance, until such
time as it can be removed safely.
