How should we act with an injured person?

If we have no first aid knowledge and there is no danger to the injured, it is best not to handle them, especially to avoid possible spinal injuries. If there is danger to the injured, we will move them keeping the head and neck always straight. As a general rule, we will never remove the helmet from an accident victim.
