Calling an ambulance is something most of us will have to do during our lifetime, whether it be for a friend, relative or stranger on the street. Often, the situation can be very stressful which makes even a simple phone call challenging. However, you can follow some of the tips below.

1) Know the correct number! Whilst you may know the number for your country, if you go abroad make sure you find out the correct number to contact the emergency services. In Europe, you can use 112 which is the European Emergency number and will work in any European country.

2) Know where you are. The ambulance service will need quite detailed information (ie, roadname and town) in order to pinpoint your exact location. This isn't always easy, especially if you are in a remote or unfamiliar area. If you don't know where you are, then try to describe your location (using landmarks, last junction etc.). Some motorways in the UK have driver location sides. If you are in a remote area then a grid reference may also be useful.

3) Give a concise description of what has happened (high speed road accident, car has hit a lamppost) including details of casualties (one casualty, unconscious but breathing) and any other relevant information such as dangers & hazards as these may require other emergency services to attend. If the situation is volatile (a fight, robbery etc.) then make sure you tell the ambulance service so that they can inform the police.

4) Speak slowly and clearly. Follow any instructions the calltaker gives you and answer their questions. Some may offer simple first aid advice over the phone.

5) Don't hang up until asked to. In some cases the operator will stay on the line until the ambulance arrives.

6) Finally, before you call, make sure the situation warrants an emergency ambulance. Hoax and inappropriate calls can tie up valuable resources. Consider whether another service could deal with your situation. In the United Kingdom you can call NHS Direct for free medical advice over the phone - 0845 4647.

Remember, calls to the emergency services are normally free so you don't require any credit. In addition, many mobile phones allow you to make an emergency phone call without a sim card or even when the keypad has been locked.
If you are treating a casualty, always try and get someone else to call an ambulance for you, so that you can concentrate on the injured person.
