In industrial and workplace environments, mechanical and electrical accidents can have severe consequences, ranging from minor injuries to fatalities. One illustrative scenario involves an electric motor-driven conveyor system in a manufacturing plant. During routine operation, an employee’s hand became caught in the rotating pulley, causing a severe injury. Upon investigation, the incident revealed several mechanical and electrical safety failures that contributed to the accident. From a mechanical safety perspective, the conveyor system lacked adequate guarding around moving parts, such as pulleys and belts. According to mechanical safety principles, rotating components should be enclosed with fixed or interlocked guards to prevent accidental contact. The absence of these guards significantly increased the risk of entanglement injuries. Furthermore, routine maintenance checks were irregular, and the lubrication and alignment of moving components were neglected, creating additional hazards such as unexpected movement or mechanical failure. Mechanical design principles emphasize the importance of fail-safe
