What does LOTO stand for in safety procedures?

• A. Lockout/Tagout
• B. Lockout/Turnout
• C. Lock and Tag
• D. Lockout/Toolout

Answer: (A)

Lockout/Tagout is a safety procedure designed to prevent the unexpected energization or startup of equipment while maintenance or repair is being done. The lockout part uses a physical lock to keep energy sources isolated, so the machinery cannot be powered on. The tagout part adds a warning tag that communicates who locked it and why, helping to prevent others from removing the lock or energizing the equipment unintentionally. Together, they provide both physical control and clear warnings, which is why this term is used universally in safety practices. The other options aren’t standard terms: turnout isn’t used, “Lock and Tag” omits the word out and isn’t the official acronym, and “Toolout” isn’t a recognized safety term.
