<h3>Rescue somebody from an accident</h3>
Once I was walking on the footpath. Suddenly I heard the noise of accident. When I reach there I saw that a car hit a boy who is seriously injured. First, I take him to a safe place and give a first aid. Then I call an ambulance.
There is a great importance of carefully transporting a victim to a safe place because carefully transporting a victim makes the injury less destructive and damaging. Improper or careless methods of transporting increase the severity of the injury and may even cause death.
