The signage requirement at major electrical installations is intended to warn about what

• A. Electrical hazards.
• B. Noise levels.
• C. Temperature extremes.
• D. Work schedules.

Answer: (A)

Electrical hazards. Signs at major electrical installations are there to alert people to the danger posed by energized equipment, high voltage, and the risk of shock or arc flash. They help establish safe distances, prompt the use of proper lockout/tagout procedures and PPE, and remind workers to avoid contact with live parts. While other concerns like noise, temperature, or work schedules can matter for safety, they’re not the primary hazard these signs are designed to warn about.
