In the event of a disaster, for example large-scale fires, explosions or floods, it must be possible to bring people and animals to safety quickly. Sirens and early warning systems are considered a central means of alerting and warning the population at an early stage. Stationary and mobile siren systems can be used for targeted alerting and information. With mobile sirens, important behavioural instructions can also be scattered, thus avoiding chaos and panic.

How should affected persons behave in such situations?

• When the siren alarm sounds, listen to the radio and read messages on apps (Alertswiss).
• When the water alarm signal sounds, leave the endangered area immediately and go to the nearest assembly point
• Avoid calling the emergency numbers, as they are often overloaded
• Follow the instructions of the authorities (announcement via mobile siren or megaphone, messages app or radio)
• Notify neighbours
• Pack emergency luggage
• Prepare the house/apartment for a longer absence (turn off the water tap, switch off electrical appliances, close windows and doors)
• Take pets with you whenever possible
• Leave the area at risk by public or private transport or go to the nearest emergency meeting point

What should be observed during an evacuation?

In general, stay calm and follow the instructions of evacuation personnel and authorities.

• Pass on your whereabouts and address to acquaintances and to the emergency personnel.
• Leave the endangered zone in a safe manner
  –  Avoid unsafe bridges and paths
  –  Stay on marked roads and footpaths

On return, check that drinking water is not contaminated (e.g. after a nearby flood or chemical spill) and check your home for electrical shorts. You can find additional information on this topic on the website Notfalltreffpunkte.ch
