The MEF organised a Free Workshop on Noise Pollution and Occupational Deafness in collaboration with the Society for the Welfare of the Deaf on Tuesday 13 October 2009 at the MEF Management School, Ground Floor, MEF-MCCI Building, Ebène CyberCity, Ebène.

It has to be noted that the Federation started an awareness campaign among employers on this subject since 1996.
