Lock Out Tag Out (LOTO) devices are crucial tools in ensuring workplace safety, particularly in industries where workers are exposed to hazardous equipment and machinery. These devices are designed to prevent accidental startup or energy release while maintenance or repair work is being performed. In this article, we will explore the purpose, types, and importance of LOTO devices in preventing workplace injuries and fatalities.

What Are Lock Out Tag Out Devices? Lock Out Tag Out devices are safety mechanisms used to control hazardous energy sources during the maintenance or servicing of machinery and equipment. The purpose of LOTO is to ensure that machines are completely de-energized and cannot be turned on by accident, thus protecting workers from potential injuries. LOTO procedures typically involve two primary actions： “Lockout” and “Tagout.” Lockout involves the use of a physical lock to secure energy-isolating devices, such as electrical switches, valves, or mechanical systems, preventing the equipment from being re-energized.
