Severnside Sirens
The Severnside Sirens are a system of Civil defense sirens located along the South Severn Estuary coastline from Redcliffe Bay to Pilning, northwest of Bristol. They are activated by Avon and Somerset Police in the event of a potential incident at one of the COMAH sites located in the area, mainly in and near Avonmouth. The system was setup in 1997 following a fire at the Albright and Wilson site in 1996. Severnside Sirens Trust Severnside Sirens Trust Limited is the organisation responsible for maintaining the system. It is a registered company (number 3348008) and charity (number 1063224) and was incorporated on 9 April 1997.

Avonmouth Severnside Siren, Sep 2019
Avonmouth is a port and outer suburb of Bristol, England, facing two rivers: the reinforced north bank of the final stage of the Avon which rises at sources in Wiltshire, Gloucestershire and Somerset; and the eastern shore of the Severn Estuary. Strategically the area has been and remains an important part of the region's maritime economy particularly for larger vessels for the unloading and exporting of heavier goods as well as in industry including warehousing, light industry, electrical power and sanitation. The area contains a junction of and is connected to the south by the M5 motorway and other roads, railway tracks and paths to the north, south-east and east. The council ward of Avonmouth and Lawrence Weston is as drawn a simplified name as it includes Shirehampton and the western end of Lawrence Weston.

Portishead, Somerset
Portishead () is a coastal village on the Severn Estuary, 8 miles (12 km) to the west of Bristol, but within the unitary authority, unitary district of North Somerset, which falls within the Ceremonial counties of England, ceremonial county of Somerset, England. It has a population of around 25,000, with a growth rate considerably in excess of surrounding towns. Portishead has a long history as a fishing port.

Warning Systems
Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored. Biological warning systems *Aposematism (e.g. warning coloration) * Climate canary *Fear * Miner's canary *Pa ...

Hallen, Gloucestershire
Hallen is a village in South Gloucestershire, England, just north of the Bristol city boundary. It is southwest of Easter Compton, northeast of Avonmouth and northwest of Henbury. The village lies at the edge of the Severn floodplain, sandwiched between the M49 and M5 motorways. It is sometimes claimed that the name "Hallen" is from the Welsh for salt, 'halen', or from an Anglo-Saxon word of the same meaning, however, 16th century spellings (e.g. Hallyende) make it clear that this is not the case; the name is apparently Middle or Early Modern English from 'hall' (hall) or 'hale' (nook, corner, stretch of alluvial land) + 'ende' (end). For administrative purposes Hallen is a ward in the civil parish of Almondsbury, although it is some 5 miles from the village of Almondsbury. Historically it was in the large parish of Henbury, and was transferred to Almondsbury in 1935 when most of Henbury was absorbed into Bristol. The Henbury Loop railway line passes the village to the ...
