Warning the population
- Public service
The population can be warned through several measures. These include emergency warnings transmitted by the Finnish Broadcasting Company and television channels as well as sound signals given by civil defence sirens.
There are approximately 75 stationary civil defence sirens in the area of the Länsi-Uusimaa Rescue Department. The fixed civil defence siren system is intended for warning the population in urban outdoor areas. A mobile civil defence siren is a device intended for installation in a vehicle or some other portable use. Mobile civil defence sirens are used to warn the population outside urban areas and in urban areas where the stationary civil defence siren system cannot be heard.
