The study focuses on the issue of extraordinary events such as disruptions in society and the involvement of non-governmental non-profit organizations. The goal is to describe the possibility of involving non-governmental non-profit organizations in dealing with extraordinary events and crisis situations. Rescue and security forces are established in the Czech Republic to deal with emergencies, whose priority mission is to save life, health, property and the environment. In addition to the state-guaranteed components, non-state nonprofit organizations are also involved in the preparation and solution of extraordinary events. The rules of cooperation and coordination according to the Act on the Integrated Rescue System, as amended, apply primarily to their coordination during emergencies. Nongovernmental non-profit organizations, which prepare for longer and systematically and are involved in the solution of extraordinary events, create platforms for cooperation and coordination focused on follow-up activities after rescue work, e.g. monitoring of the affected area, humanitarian, psychosocial, material and financial assistance, consulting and other professional assistance.
