Basics for this situation
Lost: the STOP rule
When you realise you have lost your way, stop immediately instead of carrying on. STOP stands for Stop, Think, Observe, Plan. It is often safer to stay at an easy-to-find place, especially if someone knows your trip plan.
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.
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.
Finding and assessing water sources
Water is found where it collects or emerges: in hollows, valley floors, at springs and as precipitation. Every natural source must be treated as microbiologically contaminated until proven otherwise; assessing the surroundings also decides whether chemical contamination is a concern.
