The acronym "LOTO" refers to "Lock Out/Tag Out," a critical safety procedure used in various industries to ensure that machines and equipment are properly shut off and not unexpectedly started up again during maintenance or servicing activities. This procedure involves two key components: the "lock out" part, which ensures that a device is physically locked in a safe position, preventing it from being operated, and the "tag out" aspect, which involves placing a warning tag on the equipment to inform others that it should not be operated.

This system is vital for protecting workers from potential hazards associated with the unexpected energization or startup of machinery, and it is regulated by safety standards such as OSHA in the U.S. The effectiveness of LOTO procedures relies on the proper implementation of both the lock and tag to ensure comprehensive safety measures. Understanding LOTO is essential for maintenance technologists, as it directly contributes to workplace safety and compliance with regulations.
