In industrial and manufacturing environments, safety is paramount. Among the numerous safety protocols designed to protect workers, the Lockout/Tagout (LOTO) procedure stands out as one of the most vital. At the core of this procedure are LOTO devices, which play an essential role in ensuring that equipment is properly secured during maintenance or repair. These devices help to prevent accidental machine startups, safeguarding workers from potential injuries. In this article, we will explore what LOTO devices are, how they function, and their importance in maintaining a safe work environment.

    How Do LOTO Devices Work?

    The LOTO procedure begins when an authorized employee shuts down the equipment and isolates all energy sources, including electrical, hydraulic, pneumatic, and mechanical systems. Once the energy sources are properly isolated, the worker attaches a LOTO device, such as a lock or a tag, to the control points of the equipment. These locks or tags act as a visual and physical deterrent, indicating that maintenance is in progress and that the equipment should not be operated.
