Furthermore, the rescuer's obstructed peripheral vision puts both persons at risk if the incident that caused the injury is still ongoing (fire, combat, public disturbances, etc.).
The fireman's carry, utilizing back and shoulder strength, is engineered as an emergency measure to optimize power, endurance, and mobility.
It is by no means appropriate when a stretcher is available and a viable alternative, or when the rescuer has the size and strength to easily carry the subject in a gentler, more compassionate and considerate hold.
Currently, the technique preferred in firefighting involves dragging a person by the shoulders or upper clothing in a supine position across the floor or ground.
This uses the rescuer's upper legs (the strongest muscles in the body) to push against the floor for leverage in order to pull the person towards an exit.
