Warning systems
In the event of serious accidents, crises, threats of war, or war, warnings may be issued in various ways. Learn what the different sirens mean.
Outdoor warning
The outdoor warning system, which uses loud sirens, is operational in most municipalities and around Sweden’s nuclear power plants.
The system is tested at 3:00 pm (15:00) on the first non-public-holiday Monday in March, June, September and December
Public Service Announcement (PSA)
This siren sounds for 7 seconds, followed by 14 seconds of silence. The pattern repeats for 2 minutes.
Go indoors, close all windows and doors and, if possible, switch off the ventilation. Listen to Swedish public broadcaster Sveriges Radio, channel P4 for more information.
The emergency warning and information system, PSA (Public Service Announcement), is used in emergency situations; for example, in case of hazardous air-quality events or fires that may emit toxic fumes or cause explosions. Public Service Announcements are broadcast primarily through:
- Sveriges Radio, SVT (Swedish public service television),
SVT teletext, as well as commercial radio and TV channels. - Apps that include krisinformation.se, SOS Alarm
emergency services, Sveriges Radio, and SVT. - Text messages sent to mobile phones in the affected area.
Emergency alarm
The siren sounds for 30 seconds, followed by 15 seconds of silence. The pattern is repeated for 5 minutes.
