In Hungary a new type of occupational asbestos danger appeared which affects
mainly workers engaged in asbestos removal. In the 1970s asbestos was used
for fireproof insulation in the industry and in the buildings. Since the
application of the insulation these surfaces have been damaged, in several
places broken or torn, therefore it has now neen deemed necessary to remove
the asbestos containing insulation.
The measurement and control of the airborne content of air asbestos
removal is a task related to occupational hygiene.
During the removal of asbestos from the pylons supporting the boiler
of the power station:
-
the asbestos-containing material was identified;
-
any leakage of the contaminated air was measured during the removal site;
-
the concentration of asbestos fibres in the air of the removal site - where
the workers engaged in removal were carrying out the task - was measured;
-
air clearance was also measured.
On the basis of our findings it can be stated that,
if the occupational hygiene and safety regulations are compiled with, contamination
with asbestos of the ambient air outside the working area can be effectively
prevented.
