What safety precautions are required when near third-rail or high-voltage equipment?

• A. Stay away from exposed equipment, maintain safe distances, do not touch, and follow posted warnings and procedures.
• B. Touch equipment to test if you are trained.
• C. Stand very close to inspect.
• D. Ignore warnings if in a hurry.

Answer: (A)

Safety around third-rail and high-voltage equipment centers on staying out of danger and following established rules. These systems carry dangerous voltages that can cause fatal shocks or severe injuries even if you don’t see any obvious problem, so the only safe approach is to keep away from exposed parts, maintain a safe distance, and not touch anything. Always follow posted warnings, barriers, and the procedures in place for those areas. Work in these spaces should only be done by trained, authorized personnel who have de-energized the equipment and implemented proper clearance or lockout/tagout procedures. Testing by touching is dangerous and not allowed, standing very close to inspect invites unrevealed hazards, and ignoring warnings in a hurry can lead to serious harm.
