What to do when the siren sounds

(It does not apply to the acoustic siren tests, they are always preannounced.)

Warning people is one of the most important civil protection measures. It is carried out by the siren warning signals. Most commonly they are complemented by means of mass information media (radio, television, municipal radio report).
The sound of sirens always means some risk. It warns of the possible or actual crisis situation, which endangeres lives and health of citizens, property and the environment (threat type is given by tone and duration of signal). All citizens in this situation act to their ability and by instructions issued by the competent authorities. It is necessary to hide in appropriate area or leave a threatened area.
