Dust is almost everywhere but is often not recognised as a hazard for health. But dust can have severe health consequences. Year after year around 6,000 cases of disorders of the respiratory tract caused by dust are recognized as occupational diseases in Germany. The results of the BIBB/BAuA 2012 Employment Survey show that around one in eight employees comes frequently into contact with dust, smoke, gases or vapours. Many workers in the construction industry and manufacturing industries are particularly affected.
