The sirens sound warnings to areas potentially at
risk from incidents at chemical sites in and around
Avonmouth.
They are designed to alert people living in Portishead,
Avonmouth, Shirehampton, Pilning and Severn Beach of any potential
dangers.
During an incident their alert warning will be sounded with only
those necessary to alert those at risk activated.
If you hear the sirens: go in, stay in and tune in to your local
TV and radio stations and follow the instructions of the emergency
services.
When it is safe the Severnside Sirens all clear message will be
sounded.
The sirens are tested on the third day of each month at 3pm. The
audible test is made up of a three-minute alert warning, one-minute
silence followed by a one-minute all clear
signal. |
