LOTO stands for?

• A. Load Out
• B. Line Operational Testing Only
• C. Local Operator Test Occurrence
• D. Lockout/Tagout

Answer: (D)

LOTO stands for Lockout/Tagout, the safety process used to isolate and control energy sources on equipment during maintenance. Lockout means applying a physical lock to the energy-control device (such as a switch, valve, or breaker) to prevent it from being turned on. Tagout means placing a visible tag that warns others not to operate the equipment and identifies who applied the lock and why. Using both together ensures the machine cannot be restarted while work is being done, protecting workers from unexpected energization, startup, or release of stored energy. This is a standard practice in workplace safety managed by regulations in many industries. The other phrases don’t describe this safety procedure or the acronym.
