When an accident occurs, the first reaction is often decisive; the life or death of the victim and the gravity of the consequences of the accident often depend on the speed with which first aid is administered and on the correct choice of action.
If you witness an accident or dangerous occurrence (fire, flood, medical emergency, etc.), you must immediately:

  • Protect the victim, the people in the vicinity and yourself
  • Alert the Fire Brigade (74444)
  • Help the victim (injured persons must never be moved without good reason)
  • Safeguard the evidence
