The subject of the project is the construction of an integrated system for alerting and alerting the dangers affecting the safety of residents of the Ostręłęk district. The aim of this action is to improve security against peacetime threats (strengthening and alerting the population about threats related to terrorist threats, natural, technical and weather disasters) during war (raising and alerting the population about threats from the air, chemical, biological and radioactive contamination). Under this action, security and risk prevention will be strengthened, inter alia by: development of integrated monitoring and warning systems, forecasting threats and responses in emergencies of extreme and catastrophic events or other major accidents. The construction of an integrated system of notification and alerting of the population and integrated communication will be carried out in all 11 municipalities of the Ostręłka district, i.e.: Baranowo commune, Czarnia commune, Czerwin commune, Kadzidło municipality, Goworowo commune, Lelis municipality, Łyse municipality, Olszewo-Borki commune, Rzekuń commune, Troszyn commune, urban-rural municipality Myszyniec. The principle of operation of the warning system will be based in particular by radio transmission of messages to individual stations equipped with loudspeakers mounted on the roofs of selected public buildings. The project assumes the construction of 26 new emergency points by 2017 with the possibility of increasing them to 75 according to the recommendation of the Mazowiecki Voivodeship. The system will consist of modern electronic sirens, slotted devices with switching, control, control and monitoring devices. Their connection will take place by combining with the voivodship, commune headquarters and connection to old alarm systems already on the equipment of communes.
