According to available studies, migrant workers represent a vulnerable workers' category. For this reason, the Italian law on safety and health at work (art. 11, D.Lgs 81/08) points out the need for Public Administration initiatives devoted to migrant workers' health and safety at work. Local Public Health Department of Brescia for years now had a significant commitment in migrants' health. Thanks to the collaboration of occupational physicians and expert physicians on migration health, it was developed a multidimensional method to assess working risks taking into account also the fragile conditions of migrant workers, considering both personal and social characteristics and professional experience, in order to support companies in the planning of necessary actions to improve health and safety at work. The method was shared by both local industrial association and trade unions and then tested in some manufactures.
