What does LO/TO stand for in safety terminology?

• A. Lockout/Tagout.
• B. Loadout/Turnout.
• C. Locking/Tapping.
• D. Lockdown/Tagging.

Answer: (A)

Lockout/Tagout is a safety procedure used to prevent unexpected energization or startup of equipment while it’s being serviced. Lockout means applying devices that physically isolate the energy source and hold it in a safe state. Tagout means placing a visible warning tag that communicates the equipment must not be operated and identifies the worker who applied it. These two parts together ensure machines cannot be started accidentally and that clearance is maintained during maintenance work. On ships, where electrical, hydraulic, pneumatic, and mechanical energies can pose risks, LO/TO helps protect crew during maintenance. It’s important that the person who applies the lock is the one who can remove it, and that group lockout methods are used when multiple workers are involved. Typical steps include preparing, shutting down, isolating energy sources, applying lockout devices, attaching tags, verifying zero energy, performing the work, and then removing the devices in reverse order with verification. The other terms don’t describe this specific practice of isolating energy sources to prevent unintended machine operation.
