The UK will conduct its first test of a new emergency alert service on Sunday, with millions of mobile phones set to emit a loud alarm and vibrate at 3:00pm (1400 GMT).
The national system, modelled on similar schemes in Canada, Japan, the Netherlands and the United States, aims to warn the public if there is a danger to life nearby but has generated criticism over “nanny state” intrusion.
A message will say: “This is a test of Emergency Alerts, a new UK government service that will warn you if there’s a life-threatening emergency nearby.”
Emergency services and the government hope to use the system to alert people to issues such as severe flooding and fires.
The 10-second alarm, which will sound even if phones are on silent, is expected to disrupt entertainment and sporting events, including Premier League football matches.
Organisers of the World Snooker Championship will pause play just before the alert, while the Society of London Theatre has advised its members to tell audiences to turn off their phones.
Drivers have been warned not to pick up their phones during the test, and people who do not wish to receive the alerts can opt out in their device settings.
“Keep Calm and Carry On. That is the British way and it is exactly what the country will do when they receive this test alert at 3:00 pm today,” said Deputy Prime Minister Oliver Dowden.
“The government’s number-one job is to keep people safe and this is another tool in the toolkit for emergency situations.”
But some Conservative figures have criticised the plan, with former minister Jacob Rees-Mogg urging people to defy the government’s calls and “switch off the unnecessary and intrusive alert”.
“It is back to the nanny state -– warning us, telling us, mollycoddling us when instead they should just let people get on with their lives,” he said.
Daily Mail columnist Sarah Vine, ex-wife of government minister Michael Gove, called the plans “terrifying”.
“This Sunday, at 3pm… the government intends to rattle our collective cages by invading our mobile phones — and our privacy — with its absurd emergency test signal. The notion is as terrifying as it is tiresome,” she wrote.
“Terrifying because it’s a reminder of the tyranny imposed on all of us by the technology that has invaded our homes like Japanese knotweed, infiltrating every aspect of our daily lives,” she added.
But Judy Edworthy, an international expert in alarm systems and psychology professor at the University of Plymouth, said the alert system was a positive development, even if its first airing may surprise people.
“Despite the message explaining it is a test, I expect some people may well be astonished,” she told the domestic Press Association.
“If it makes people look at their phones and read the message, and then act on it, it can be said to have worked,” she added.
MPs also criticised the decision to hand the lucrative IT contract for the alert system to Fujitsu, the Japanese firm responsible for faulty software in the Post Office system that led to innocent sub-postmasters receiving fraud convictions.
