If there is an air raid, you must immediately take cover in a shelter or other protective place. Choose the nearest one. You may also need to evacuate an area in the event of a possible military offensive.

Warnings are broadcast through a variety of channels, including air raid warning and the Swedish public broadcaster Sveriges Radio, channel P4.

Civil defence shelters provide protection against shockwaves and bomb fragments. They also protect against the blast and heat waves from a nuclear weapon. Shelters provide better protection than other spaces when it comes to radioactive fallout, gas from chemical weapons, and biological weapons.

Other places in which to seek shelter

Cellars, garages and below-ground metro stations also provide cover during an air raid. Tunnels and walls can also offer some protection. Being indoors is better than outdoors, preferably in a room without windows.

If you are outside and don't have time to take cover, you must lie down on the ground. Preferably in a small pit or ditch.

When you hear the "All clear" siren, you may leave your shelter. Help people who are injured or trapped.
