A common scenario in industrial settings involves an electrical shock incident during routine maintenance of a motor-driven conveyor system. In this case, a maintenance worker was performing inspection and lubrication of a conveyor motor while the machine was still partially energized. The worker received a severe electric shock, resulting in serious injury. Analyzing this incident requires integrating principles from both mechanical and electrical safety management. From a mechanical safety perspective, one major oversight was the failure to implement proper lockout/tagout (LOTO) procedures. The conveyor system, being mechanically powered, posed multiple hazards including moving parts, pinch points, and stored kinetic energy. The absence of mechanical isolation allowed the motor
