Occupational injuries (OI) are a relevant issue in workplaces, being responsible for a range of individual and socio-economic consequences, with an enormous toll paid by workers, enterprises and society. Despite all these issues, OI prevention has not received significant field research attention, with studies mainly addressed to reporting data a posteriori instead of evaluating the effectiveness of prevention programs. In addition, the role of occupational physician (OP) seems to be largely underplayed. OP may and should be involved in OI prevention and control, in respect of codes of ethics, current legislation and scientific evidence. A multifaceted intervention in foundries, which showed effectiveness in reducing OI rates and improving quantitative and qualitative outcomes, gave us the opportunity to highlight OP's key role in implementing good occupational health and safety practices in workplaces.
