Despite the implementation of collective protective measures, the exposure of hospital workers involved in the preparation and  administration of cytotoxic drugs may still be referred to as an occupational health hazard. Many international studies have demonstrated that workers are being exposed despite the implementation of protective measures(1-6). To understand the problem, the risks need to be identified by considering the potential sources of contamination and the routes of exposure, and the weak points in the measures implemented for the protection of health workers need to be analysed.
