Alarms and behaviour guidelines

1. Overview

In the event of a disaster, warning should be given to the entire population in the area concerned. To this end, Switzerland has a dense network of sirens covering the entire country.

Most disasters are of local or regional magnitude.

Geneva currently has 116 fixed sirens across the canton. Inside buildings open to the general public, alarms are relayed by telephone and instructions are issued to occupants.
