How does the 'two-person rule' enhance safety for certain electrical tasks?

• A. It avoids the need for PPE.
• B. A second qualified person provides supervision, rescue readiness, and cross-checks.
• C. Two people cannot work on different tasks.
• D. Two people avoid PPE.

Answer: (B)

Having a second qualified worker present during certain electrical tasks creates a safety net: one person does the work while the other supervises, is ready to perform a rescue if someone is shocked or incapacitated, and cross-checks that energy isolation, procedures, and PPE are being used correctly. This redundancy helps catch mistakes, ensures proper lockout/tagout and energization verification, and confirms that safe work practices and arc-flash boundaries are followed. The second person can also immediately assist or summon help if something goes wrong, which dramatically reduces the risk of injury. PPE remains required regardless of the two-person presence, and the rule is about safety oversight and readiness, not about eliminating PPE or forbidding collaboration on different tasks.
