Severnside Sirens

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.
