If two workers are involved and the disconnect feeding the transformer is deenergized and locked out, what is the correct method to proceed?

• A. The panel is locked out, so you can proceed
• B. Install your lock
• C. Wait until the other person is finished
• D. Proceed after the other person finishes without a lockout

Answer: (B)

The key idea is that lockout/tagout protects you by giving you personal control over the energy isolation. When two workers are involved and the transformer disconnect is already deenergized and locked, you still must apply your own lock and tag. This ensures no one can re-energize the circuit while you’re working, and only you can remove your lock. Relying on another person’s lock isn’t safe, because that lock could be removed or mishandled. Waiting for the other person to finish or proceeding without your own lock don’t provide personal protection and aren’t allowed. Installing your lock is the correct step.
