A treadmill is a piece of exercising equipment that consists of a conveyor belt rotated either manually or by a motor. The user will normally walk, jog or run on this device.

The most significant risk associated with the use of treadmills is friction burns, especially to young children playing on or near a treadmill. The results of these injuries can range from minor burns to serious burns requiring skin grafts and potential permanent loss of the use of hands or fingers.
