Under what conditions is a second qualified person required?

• A. Energized work, remote locations, or unfamiliar equipment
• B. During routine, de-energized maintenance
• C. Only during high voltage over 1000V
• D. Never required

Answer: (A)

A second qualified person is required whenever work involves energized equipment or added risk conditions. This ensures another trained individual is available to verify that energy has been isolated, to supervise the proper use of PPE and procedures, and to assist or intervene if anything goes wrong. Energized work creates shock and arc-flash hazards, so having a second qualified person adds a crucial layer of safety, especially in remote locations where help isn’t readily available or when the equipment is unfamiliar and hazards aren’t fully known. If the work is fully de-energized and properly isolated for routine maintenance, a second person isn’t typically required. The need isn’t determined by voltage alone but by the presence of energized work or other higher-risk conditions.
