Over the last decades, the globalisation and important geopolitical changes have widened the spatial boundaries of international migrations which have reached a so global scope today that they influence the economic, political and social trend of countries of origin, transit and destination. According to the UN, the international labour mobility involved more than 200 million people in 2010, that is approximately 10% of the world's total population. In Italy, in the beginning of 2010 foreign residents amounted to 4.2 million, that is to say, 7% of the total population (ISTAT, 2011). Host countries have been forced to implement a series of policies aimed at combating illegal immigration and employment of foreign people. Special attention must be given to the issue of migrant workers who have become increasingly important actors in the social and productive sectors and, as a consequence, the need for preventive and protective measures taking into consideration the specific work-related hazards is growing more and more urgent. With this respect, the regulatory framework for occupational health and safety now contains explicit references to migrant workers as provided in the Leg. Decree 81/08 with subsequent integrations and modifications. First of all, the issue of occupational health and safety for migrant workers must take into account of the linguistic, social and cultural problems of the different ethnical groups that are present in our country.
