Lock Out Tag Out (LOTO) is a crucial safety procedure designed to protect workers from the unexpected release of hazardous energy while performing maintenance, repairs, or service operations on machinery or equipment. These injuries, often caused by accidental activation of machines or exposure to dangerous energy sources, can result in serious accidents or fatalities. LOTO procedures ensure that equipment is properly shut off and cannot be re-energized until maintenance is complete, making it a fundamental practice for industrial environments where heavy machinery or electrical systems are involved.
What is Lock Out Tag Out? Lock Out Tag Out refers to two primary actions used to control hazardous energy during equipment maintenance： “Lock Out” and “Tag Out.” These terms represent physical actions and visual warnings aimed at preventing equipment from being accidentally energized. While both methods are critical, they serve different functions. Lock Out involves physically securing the equipment’s energy-isolating devices (like switches, valves, or circuit breakers) using a lock. This lock prevents others from operating or activating the equipment, ensuring that only the person who applied the lock can remove it.
