• Existing asbestos is disturbed by renovation work or the installation of
new heating, electrical or communication systems.
• Asbestos removal is undertaken without adequate safety precautions
and properly trained personnel.
What Are The Health Hazards?
Asbestos, according to the medical experts, increases the risk of four
serious diseases:
1, Asbestosis: This illness results from chronic exposure to airborne
asbestos fibers and is not a disease found in the general population. It
involves the scarring of lung tissue and may lead to shortness of breath or
more serious lung damage.
