A common accident scenario in industrial settings involves an electrical maintenance worker receiving a severe electric shock while attempting to repair a live motor control panel. In this case, the worker opened the panel without isolating the power supply, leading to accidental contact with energized components. The incident resulted in serious burns and hospitalization, demonstrating the dangers of inadequate mechanical and electrical safety management. Analyzing this event using principles from both mechanical and electrical safety management provides a clearer understanding of its root causes and necessary prevention measures. From the electrical safety perspective, the primary issue was the absence of lockout-tagout (LOTO) procedures. The worker did not disconnect or lock the main power source, leaving the equipment energized during maintenance.
