In the realm of industrial safety, ensuring the well-being of workers during maintenance and repair operations is paramount. One of the most effective and universally recognized safety procedures employed to protect workers is the Lock Out Tag Out (LOTO) system. The LOTO procedure aims to prevent the unexpected release of hazardous energy during service or maintenance work, protecting personnel from potential injuries or fatalities. Central to this system are the Lock Out Tag Out locks, a critical tool that helps isolate energy sources and signals to others that machinery is undergoing repair.

What is Lock Out Tag Out (LOTO)? Lock Out Tag Out is a safety procedure used in workplaces that involves isolating machinery or equipment from its energy sources before repair or maintenance work begins. The primary goal is to prevent the accidental release of hazardous energy—whether electrical, mechanical, hydraulic, or other types—while workers are performing tasks on or around machinery. The system is designed to ensure that the energy supply to a machine is fully deactivated and that it cannot be accidentally reactivated while the worker is engaged in maintenance activities. The two essential components of LOTO are：
