The simple process allows a person to call police or other emergency services in circumstance where it may not be safe to talk out loud or make a noise.
Here’s how to place an emergency call when you’re scared to speak:
When you call 999, an operator asks which emergency service you require before rerouting the call to the police, ambulance service or fire brigade.
If a 999 caller doesn’t talk, the operator will ask them to cough or make another audible sound.
In certain situations, it may not be safe to make a noise – for example it could alert a potential attacker to your exact whereabouts.
Emergency services simply don’t have the resources to investigate every call made to 999 during which no sound is made.
However there’s a simple way of signalling that it’s a genuine emergency and you haven’t just accidentally pocket-dialled.
The procedure is called Silent Solution and it was created so people in an emergency can call the police in dangerous situations.
After you dial 999 and you’ve been unable to audibly signal to the operator, your call will be forwarded to an operating system.
If you’re in danger, dial 55 otherwise the call will be terminated.
