Electrical Safety in an Operating Theatre

The importance of following electrical safety guidelines in an operating theatre will ensure the safety of the patient during surgery. Operating theatre electrical systems must comply with the National Electric Code (NEC), Article 517, for safety in hospitals.

  1. Equipment

    • Electrical shocks generally result from faulty equipment. Check for cracked, frayed or bare wiring on equipment cords and repair damaged plugs, cords or insulation. Never operate equipment with missing ground plugs. Avoid plugging equipment into damaged receptacles and do not use extension cords without prior approval.

    Handling

    • When unplugging power cords, grasp the plug and never pull on the cord. Turn power switches to the off position prior to plugging equipment into wall receptacles. Do not plug in equipment with wet cords or plug equipment in with wet hands. Refrain from blocking the entrance to electrical panels with equipment and carts. Avoid draping cords over sharp or hot objects and do not place cords where they can cause a tripping danger.

    Wiring

    • Hospital electrical systems must consist of two independent wiring structures separated from all other wiring instrumentation, according to the NEC. The emergency system supplies circuits necessary to life safety and critical care of patients. The equipment system provides the major electrical equipment required for patient care and essential hospital operation.
