How could I reach emergency ? Someone is badly injured
In many countries, emergency services are reachable by phone, by dialing a three digit number. The exact number will vary depending on which country you are located in. For example:

USA: 911
UK: 999
Australia: 000
Continental Europe: 112

If your country is not listed here, please tell me which country it is and I will try to find the correct number for emergency services.

Once you are in contact with emergency services, notify them of your location in as much detail and possible and describe the nature of the injuries. Follow any instructions they give you until help arrives.
