What should be done if only one rescuer is available to move a casualty?

When a single rescuer is available to move a casualty, utilizing a dragging technique is the most practical and effective choice. This method allows the rescuer to move the casualty without needing significant assistance or risking their own safety. Dragging techniques, such as the "clothes drag" or the "ankle drag," enable the rescuer to pull the casualty to safety while keeping the casualty's head and neck aligned, which is crucial in preventing further injury, especially if a spinal injury is suspected.

Other options might involve waiting for additional help, which can delay necessary medical attention, or using a fireman's carry, which can be physically demanding and potentially unsafe if the rescuer is not trained or if the casualty is heavy or incapacitated. Securing the casualty and calling for backup may be appropriate in some situations but does not advance the casualty's movement toward safety in a timely manner. Thus, using a dragging technique is a key skill for a lone rescuer in emergencies, ensuring that they can move the casualty while maintaining a focus on safety and efficiency.
