What term describes placing a tag on a disconnect to indicate it is out of service?

• A. Lockout
• B. Tagout
• C. Grounding
• D. Isolation

Answer: (B)

Tagout describes placing a tag on a disconnect to show it is out of service. The tag serves as a warning to not energize the equipment and typically records who applied it and when. This is the tagging part of the energy-control process. If a physical lock is used instead (or in addition), that would be lockout. Grounding and isolation refer to other safety steps—grounding dissipates stored energy, and isolation means separating the energy source from the equipment, but they don’t describe the tagging action.
