The aim of this paper is to identify the legislative basis referring to the position and activities of the Rescue and Fire Brigade Corps, the Medical Rescue Service and the Voluntary Municipal Fire Brigade in Slovakia. The paper deals with the results of an analysis based on a questionnaire research focusing on cooperation between professional and voluntary fire brigades and the Medical Rescue Service during common interventions. The research includes answers from 97 respondents. The analysis shows that cooperation between the afore-mentioned rescue units is in general good, however it has some shortcomings and problems, such as poor communication and insufficient common training. In favour of improving cooperation, members of the rescue units recommend not only frequent tactical training focusing on particular situations, but also professional training and other similar common meetings.
