Basics for this situation
In an emergency: stay safe, call, get help
First-aid courses teach the first minutes of an emergency in the same order every time: take in the situation, protect yourself and others, call the local emergency number (112 in the EU), have other helpers fetch an AED and stay with the casualty. This text does not replace a first-aid course.
Making an emergency call: what to say, staying reachable
A good emergency call is short, calm and structured: where it happened, what happened, how many people are affected, what injuries or hazards – and then wait for questions. The local emergency number in the EU is 112. After the call, stay reachable and conserve the battery.
Reading and sharing your location: coordinates, apps, description
In an emergency rescuers need to know where you are. Smartphones show coordinates even without a data connection, many countries transmit location automatically during an emergency call, and location apps can share positions as coordinates, a link or a code. A description with terrain features always helps as well.
How the body loses heat
The body loses heat in four ways: conduction, convection, radiation and evaporation. A shelter is only as good as its ability to interrupt these paths – a roof and walls are not enough if the ground draws heat away or clothing is wet.
