In industrial environments, safety is a top priority, and ensuring that workers are not exposed to unnecessary risks is crucial. One of the most effective ways to maintain safety during maintenance and repair tasks is through the use of LOTO locks—a term that stands for Lockout/Tagout. These specialized devices are integral to preventing accidents and injuries caused by the accidental release of hazardous energy while working on machinery or equipment. In this article, we will explore the significance of LOTO locks, how they function, and their critical role in workplace safety.

What Are LOTO Locks? LOTO locks are safety devices designed to secure the energy sources of machines and equipment, ensuring they are not inadvertently powered on during maintenance. The primary purpose of these locks is to protect workers from the dangers of unexpected machinery start-ups, electrical surges, or the release of pressurized systems, such as gas or steam. These locks are typically used in conjunction with Lockout/Tagout procedures, a system of control that isolates the energy sources of equipment during servicing. The LOTO lockout system is often composed of two main components：
