What is the primary purpose of the Lockout/Tagout (LOTO) standard?

The primary purpose of the Lockout/Tagout (LOTO) standard is to prevent accidental startup or release of stored energy. This is crucial for maintaining the safety of workers during maintenance and servicing activities. When machinery is being repaired or maintained, it may contain residual energy or be at risk of being inadvertently activated. The LOTO standards require that equipment be properly shut down and rendered inoperative, with locks and tags used to ensure that the energy sources—whether electrical, mechanical, hydraulic, or pneumatic—are secured. This process helps prevent injuries that could occur if a worker were to unknowingly start a machine or utilize an energy source while someone else is working on it. By prioritizing the elimination of these risks, LOTO enables a safe work environment during maintenance tasks.
