(I changed this post 18/12/12) to reflect correspondence from the Victorian Fire Commssioner’s office. )
The Victorian Government in Australia has announced a pilot program to establish sirens in some bushfire prone communities this year.
Sirens are a form of warning. As can be seen from previous posts, many believe they are effective externally only; should be part of an integrated warning system; and need a voice activated announcement to provide context.
Many communities feel safer with sirens, other’s tend to believe they prevent people from being pro-active in their hazards behaviour. This leads to complacency.
Overwarning is an issue.
The Victorian system is not integrated.
(Note change here: This sentence from me is not correct: The Fire Commssioner’s office says: “Sirens are to be integrated with osom which means that the warnings go to social media, emergency broadcasters, website and also sets the sirens off.”)
The Victorian Bushfire Commissioner web site says they can be used as part of Victoria’s warning system for all hazards – including flood, fire and storm.
“In the future a siren sounded anywhere in Victoria will have one of two consistent meanings:
- CFA Brigade siren – a signal sounded for up to 90-seconds will indicate a CFA Brigade has responded to an emergency incident nearby.
- CFA Brigade sirens and community sirens – a prolonged, 5-minute signal will indicate a significant emergency is underway in the local area, conditions are changing and people must seek further information and take immediate action.
The sound of a siren is a trigger for people to seek more information from other sources, including emergency broadcasters, the Victorian Bushfire Information Line or emergency services websites.
The sirens in Victoria appear to be tone only.
Here is the Victorian Govermnment news release:
Sirens to alert community at pilot locations this summer
Thursday, 22 November 2012 From the Deputy Premier, From the Minister for Police and Emergency Services
Sirens will be used as an additional warning tool across 13 local government areas this summer fire season, as part of a Victorian Coalition Government pilot program . The pilot will see 46 community sirens used to alert 39 towns or communities to any significant emergency or potential danger that could impact on them. Of these sirens, 28 will be located across three council areas to alert communities in the fire-prone Dandenong Ranges.
Deputy Premier and Minister for Police and Emergency Services Peter Ryan said the pilot locations were chosen based on their bushfire risk and access to a working CFA brigade siren or community siren.
“We know Victorian communities want sirens to be used as a warning tool and this pilot will make sure the correct processes are in place, and the community understands their use, before they are rolled out in other appropriate locations across Victoria,” Mr Ryan said.
“The pilot locations are primarily those where CFA brigade stations or infrastructure already have working sirens, however community-owned sirens in Ferny Creek, Steel’s Creek, Blackwood and Greendale will also be activated.
“Sirens are not a stand-alone means of warning the community, they are designed to alert people when a significant emergency is threatening the local area and to seek further information from other channels.
“Residents should then refer to alerts and warnings issued through emergency broadcasters, www.cfa.vic.gov.au, www.ses.vic.gov.au, SKY News television, local ABC radio, the FireReady app for smartphones, and the Victorian Bushfire Information Line or Flood Information Line,” Mr Ryan said. All sirens are being upgraded to connect to existing warning systems so the community has access to multiple, simultaneous alerts about emergency incidents in their area. The sirens will warn of fire, hazardous material incidents, floods and severe storms, in line with the Use of Sirens for Brigade and Community Alerting policy released by the Coalition Government in May.
The pilot siren locations are Lavers Hill, Wye River, Lorne, Cockatoo, Gembrook, Mt Martha, Noojee, Boolarra, Yinnar, Loch Sport, Kinglake, Kinglake West, Flowerdale, The Basin, Belgrave, Belgrave South, Belgrave Heights, Clematis, Emerald, Olinda, Kallista, The Patch, Kalorama, Mt Evelyn, Menzies Creek, Monbulk, Sassafras, Selby, Upwey, Upper Ferntree Gully, Silvan, Narre Warren East, Macclesfield, Blackwood, Greendale, Euroa, Myrtleford, Ferny Creek and Steels Creek. Some locations will have more than one siren. For more information about the Use of Sirens for Brigade and Community Alerting or the sirens pilot visit www.firecommissioner.vic.gov.au
