A safety control system for power operated equipment ensures operator safety by immediately disconnecting or reversing the power drive from a power driven rotating member such as a circular blade of a meat trimming knife or a toothed feed shaft of a meat skinning machine, upon a metal conductive glove worn by the operator, contacting the blade or toothed shaft or other electrically isolated portion of the equipment. The operator\s glove is electrically connected to a safety switch which immediately disconnects or reverses the power drive from the rotating member upon the glove completing a circuit upon contact with the electrically isolated portion of the equipment. A moisture impervious dielectric plastic glove preferably is worn by the operator to prevent the moisture in the meat from conducting current between the metal glove and isolated machine portion until the plastic glove is cut and contact made with the metal glove. A switch requires manual actuation to connect the power drive to the rotatable member. The metal gloves are connected to the safety switch by electrodes secured to the operator\s wrists in close proximity to the metal gloves. In a second embodiment the gloves are connected to the safety switch by a pair of metal electrodes mounted on the operator\s garment adjacent the thigh areas which contact another pair of electrodes provided by a pair of pivotally mounted conductive arms which extend outwardly from the power operated equipment.

A safety control system for power operated equipment of the type having a rotating metal component including: (a) a reversible electric motor operatively connected to the metal component for rotating said component; (b) control means for operatively connecting the motor to the rotating metal component; (c) electrical conductive gloves adapted to be worn by an operator of the power operated equipment; (d) moisture impervious dielectric gloves adapted to be worn by the operator over the electrical conductive gloves; and (e) said control means further including safety switch means electrically connected to the conductive gloves and rotating metal component for reversing the direction of rotation of the motor and the direction of rotation of the rotating metal component to prevent injury to the operator if at least one of the operator\s conductive gloves contacts the rotatable metal component.
