Download scientific diagram | Operator at a sewing machine with a superimposed schematic that shows a hand-to-foot contact current pathway. The left hand makes direct contact with a voltage source on the mechanism. The left foot is in close proximity to the grounded foot pedal. This forms either a capacitive connection or a resistive connection through the shoe from the body to the foot pedal. The foot pedal is connected to the grounding conductor by the table frame. (This is machine D used in the laboratory simulations—see Methods and Results.) from publication: Equipment Grounding Affects Contact Current Exposure: A Case Study of Sewing Machines | Exposure to contact current may occur when the body is in contact with two conductive surfaces with different electrical potentials. To date, no published data that describe such exposures or electrical conditions that may predispose to such exposures exist.
