Warning in the event of a disaster

You will be alerted by the siren and via NL-Alert on your cell phone (if set up). Do you hear the siren or receive an NL-Alert? Stay as calm as possible, go inside, close doors and windows and turn on radio or TV on the regional station for information.

The sirens are tested every first Monday of the month at noon.

What should you do in the event of a siren?

Get inside the nearest building as soon as possible. Close doors and windows and turn off ventilation. Let people who ring your doorbell take shelter inside. Warn others who did not hear the siren.

Listen to disaster broadcaster for instructions. In case of a disaster in your area, this is the regional broadcaster on radio and TV, Omrop Fryslân. In case of a national disaster, this is Nederland 1 or Radio 1. Also check Fryslân Veilig for up-to-date information.

What not to do when the siren goes off?

Do not call 112 or the local police, fire department or ambulance unless there is an immediate emergency for yourself. Telephone exchanges must remain free for emergency assistance.

Please do not take your children out of school. The school administration will catch them and make sure they are safe.

If you need to leave your home (evacuation)

Shut off gas, water and electricity. Take only the most important items with you. Lock your home securely and let neighbors know there is an evacuation.

In case of fire, call 911: stay low to the ground to avoid smoke. Can't get away? Stand near a window so the fire department can see you. Follow the route indicated by the police or emergency services.

If possible, take others with you who do not have transportation. Listen to traffic information on the radio on the way. Go to the shelter or to family or friends outside the disaster area.

There is special transportation for the needy, the elderly and schoolchildren during a disaster or crisis. The institutions where these people are at the time provide this.
