Dial 112 if you need police, fire department or an ambulance.

If you call 112 from a mobile phone, they will ask what city you're in, because prefix 06 is not city-specific.

In an emergency, you will need to tell them where you are. This is a good argument for learning to pronounce where you are. I keeping hitting you over the head with that, but it's real.

Also, if you suspect a gas leak in a building, call 0800-9009.
