LOTO stands for what?

• A. Lockout/Tagout
• B. Lockover/Tagout
• C. Lockout/Time-out
• D. Lockup/Tagout

Answer: (A)

LOTO is a safety practice used to prevent the unexpected energization of equipment during maintenance. It stands for Lockout/Tagout. The lockout part physically locks the energy source—like a switch, valve, or breaker—so the machine cannot be turned on. The tagout part adds a warning tag with who is working and what is being done, indicating the equipment should not be operated. Together, they reduce the risk of injury from sudden startup or stored energy release. Other terms like Lockover or Lockup aren’t standard safety terms, and Time-out isn’t related to energy isolation. So the correct term is Lockout/Tagout.
