How to behave when calling the emergency line
When calling the emergency line, it is crucial to keep a cool head. The operator on the other end is a trained professional and will guide you step by step. Your task is not to panic and to answer questions as clearly as possible.
1. Choose the correct number: 155 or 112?
- Call 155 (Emergency Medical Service): If it is exclusively a medical problem (heart attack, unconsciousness, severe injury, choking). You will be connected directly to a medical operator, saving you seconds.
- Call 112 (Integrated Rescue System): If it is a traffic accident, fire, or a situation where, in addition to an ambulance, you also need the police or firefighters.
2. What you must tell the operator
Do not stray from the topic and always answer exactly what is asked:
- WHERE it happened: In the village, state the street and number, in the mountains the path, kilometer marker or landmarks (bridges, gas stations).
- WHAT exactly happened: Briefly describe the situation (e.g., „collision of two cars“, „man collapsed and is not breathing“).
- WHO it happened to: State the number of injured, their condition (consciousness, breathing, bleeding), age, and gender.
- WHO is calling: Your name and phone number for return contact.
3. Communication principles during the call
- Turn on speakerphone: You will have your hands free to provide first aid.
- Listen to the operator's instructions: The operator will instruct you on how to stop bleeding or resuscitate until the ambulance arrives.
- Don't worry about delaying: While the operator is advising you, the ambulance is already on its way. The data is being sent to the crew simultaneously.
- Never hang up first: The operator will end the call only when they have all the necessary information.
4. What to do without a GSM signal?
- Line 112: Try dialing it even without your operator's signal (the phone will use another operator's network). Try restarting your mobile and selecting "Emergency call".
- HZS app: Press the button to call for help. The app will send an emergency SMS with GPS location, which will go through even with minimal signal.
- Movement: If the situation allows, move higher toward the ridge or to an open area.

Alpine emergency signal
If technology fails, use an audible (whistle, shout) or light signal: 6 times per minute (every 10 seconds), then a 1-minute pause. The rescuers' response is 3 times per minute.

Key principle to conclude
The best rescue without a signal starts even before the hike. Always inform someone of your route and expected return time. If you don't check in, your loved ones will alert the Mountain Rescue Service (HZS), which will know exactly where to look for you.
