Some Alberta communities are accustomed to a every day, noisy discover that it’s midday, whereas others could discover the sound alarming. The CBC’s Lauren Fink visited communities which have had sirens for many years to search out out why they’re there and why they blare.
The federal authorities was behind the push to put in the warning techniques in communities, mentioned Eric Strikwerda, affiliate professor of historical past at Athabasca College.
“It began out as a program meant to place air raid sirens in cities of fifty,000 individuals or extra,” he mentioned. “In a while, they began to put in them in smaller centres.”
Summon the brigade
Sirens additionally turned a sensible answer for native hearth departments.
Within the central Alberta city of Bowden, about 45 kilometres south of Crimson Deer, a faculty bell was used to alert firefighters when the city first began exploring the concept of buying a siren in 1943.
Bowden bought its siren on July 14, 1952. Greater than 70 years later, its sound nonetheless fills the city on daily basis at midday.
In Wabamun, Alta., a hamlet about 70 kilometres west of Edmonton, its siren was put in in its present location in 1965 — one yr after the institution of a hearth division that would supply safety to the entire municipal district.
To get firefighters to an incident, residents would name an marketed quantity that rang at three totally different telephones. When one of many telephones was answered, the main points of the emergency had been written down and the operator would push a button on the facet of the cellphone.
That might set off the siren to go off 10 occasions.
Invoice Purdy was on the unique hearth crew in 1964 and nonetheless acts because the auxiliary honorary chief for Parkland Fireplace Companies. He mentioned the siren wanted to be examined every day to make certain it was functioning correctly.
“It’s so overwhelming to look again … and simply see the modifications which have occurred in the entire hearth companies,” mentioned Purdy.
When Wabamun moved to a pager system within the mid-’70s, the siren was now not used as the first alert system.
However nonetheless, it nonetheless sounds on daily basis at midday.
When as soon as will not be sufficient
Within the village of Holden, about 100 kilometres southeast of Edmonton, the siren goes off thrice a day — at midday, 6 p.m. and 9 p.m.
There was a time that it went off at 8 a.m. as properly, mentioned Michele Mulder, a long-time resident of the village.

“It was only a very nice sort of reminder for everyone”
Another Alberta communities the place the noon-hour siren name continues embody Bashaw, Boyle, Valleyview and Warburg.
There are additionally many cities the place the sirens have been silenced.
“By the mid-Nineteen Nineties, most air raid sirens had largely disappeared,” mentioned Strikwerda, noting that cities had requested the federal authorities take away them.
Again in Thorsby, there was a grievance in 2013 concerning the every day bellowing so the city contracted Alberta Well being Companies (AHS) to do a noise survey.
The outcomes famous that whereas the sounds is perhaps annoying, it wasn’t a well being hazard.
“There is no such thing as a proof to assist the decibel degree and period of noise coming from the Thorsby civil defence siren constitutes a listening to impairment hazard,” said the report, which was offered to CBC.
AHS supplied suggestions together with discontinuing it aside from in an emergency, dampening the sound or shortening the period.
The city’s mayor, Darryl Hostyn, mentioned a plebiscite on the subject resulted in a call to maintain the siren’s every day noon-hour name, which lasts about one minute ��— a brief loud burst adopted by about 50 seconds because it winds down.
Whereas there’s largely no sensible use for these sirens now, they’re a sign of Canadian historical past.
“I assume it’s simply one other piece of historical past in a small city that disappears,” mentioned Hostyn.
“It’s similar to the go away of the [grain] elevators and every thing else,” he added.
“Fairly quickly, what’s left?”
