Hrvatska gorska služba spašavanja (Croatian mountain rescue service, HGSS) is a national association founded with the aim of preventing accidents, rescue and providing first aid in inaccessible mountain areas, and in special conditions in urban areas in order to prevent and avoid accidents, save human life, health and property. For every successful operating job communication is important, especially the smooth flow of messages from the sender to the recipient, so that the recipient can respond to the sender or act on his message. This final work presents the communication of HGSS on the social networks Facebook and Instagram. Communication through Facebook and Instagram enables HGSS to have direct contact with citizens, which was not possible through any other mass media. Through two-way communication made possible by social networks, information reaches the target audience. Direct communication between HGSS and citizens is of great importance for the timely provision of assistance in various types of accidents in which every minute can be important for preserving someone's life and health, and it is also of great importance in preventing the spread of incorrect information and panic in some difficult situations such as fires, earthquakes and other disasters.
