Lock Out Tag Out (LOTO) is a crucial workplace safety protocol designed to protect workers from the dangers associated with the accidental release of hazardous energy during equipment maintenance or repair. This system plays a pivotal role in preventing workplace injuries and fatalities, particularly in industries where machinery or equipment presents significant risks, such as manufacturing, construction, and utilities. In this article, we will explore the fundamental principles of LOTO, the procedures involved, and its importance in ensuring a safe working environment.

What is Lock Out Tag Out (LOTO)? Lock Out Tag Out refers to a set of safety procedures used to isolate hazardous energy sources when maintaining, servicing, or repairing machinery and equipment. The process involves two primary actions： locking and tagging. The “lock out” phase involves physically locking energy-isolating devices in the “off” or neutral position, while the “tag out” phase involves placing a warning tag on the device to indicate that it should not be operated. These procedures ensure that workers are not exposed to risks like electrocution, mechanical injuries, or chemical exposure, which can occur if machinery is accidentally started while maintenance is being carried out.
