What is the purpose of the two-person rule in electrical safety?

• A. To perform the work faster
• B. To ensure another qualified person is present to help enforce controls, assist in emergencies, and verify procedures.
• C. To supervise trainees only
• D. To replace the need for lockout/tagout

Answer: (B)

Having a second qualified person on site provides essential safety redundancy. When work involves energized equipment or high-risk tasks, the additional person helps ensure that all safety controls are actually followed, not just planned on paper. They can verify that lockout/tagout procedures are properly applied, confirm that the correct arc-flash boundaries and PPE are in place, and watch for hazards the first worker might miss. In an emergency, this helper can take immediate action—calling for help, assisting with a rescue, or retrieving needed equipment—so responses are faster and more effective. This rule is about enhancing safety through collaboration and quick support, not about speeding up work, supervising trainees alone, or replacing lockout/tagout; it complements and strengthens those practices by providing oversight and backup.
