What does LOTO stand for in electrical maintenance procedures?

LOTO stands for Lock And Tag Out. This is a critical safety procedure used in electrical maintenance to ensure that machines and electrical systems are properly shut down and not able to be restarted while maintenance or servicing is being performed.

The process involves "locking out" the energy source using a lock that can only be removed by the technician who will be performing the work. Additionally, "tagging out" involves placing a warning tag on the lock that indicates who is working on the equipment and prevents others from attempting to start the machine. This procedure significantly reduces the risk of accidental energization or unexpected startup during maintenance, thereby enhancing safety for workers.

The other options do not accurately reflect the established terminology used in safety protocols for maintenance procedures. This makes Lock And Tag Out the correct representation of the LOTO acronym, emphasizing its purpose in promoting safety in electrical work environments.
