This invention utilizes a meat skinning machine having a frame, a skinning blade, a rotatable gripping roll closely positioned adjacent the blade, an electrical braking motor operatively connected to the roll and to an electrical power source, and a danger zone defined by the area approximate to the roll closely adjacent the blade. The braking motor has a normally inoperative braking means adapted to stop the motor substantially instantaneously when becoming operative. A safety circuit is electrically connected to the braking motor, blade and roll. The safety circuit is normally open, but closes when the blade and roll are electrically connected by any electroconducting means, like an electroconductive operator 8 glove, that simultaneously comes into electrical contact with the blade and roll. Closing the safety circuit actuates the braking means substantially instantaneously, stopping the braking motor and stopping the roll substantially instantaneously. Closely spaced terminals may also be provided in a danger area of the machine, causing power to be immediately withdrawn whenever one of the electroconducting gloves contact the terminals. Another alternative provides spaced pairs of power switch terminals on the machine, closable only by simultaneous but separate contact between the terminals of each switch with the respective electroconducting gloves. The method of the invention includes providing pairs of spaced power switch terminals on the machine, closable only by simultaneous but separate contact between the terminals of each switch with the respective electroconducting gloves.
