A safety warning method used to indicate that traction power substations or other equipment have been de-energized for maintenance is called what?

• A. Panic Brake
• B. Red Tag
• C. Route Selector
• D. Right-of-Way

Answer: (B)

In safety practices, when maintenance is done on traction power equipment, a tag-out system is used to clearly indicate the equipment is de-energized and must not be operated. The specific method involves placing a red tag on the equipment (often with the maintainer’s name and the reason) to warn others not to re-energize it until the tag is removed by an authorized person after proper verification. This makes the status visible to all workers and helps prevent accidental energizing during maintenance. The other options don’t fit this purpose: a panic brake is related to emergency stopping, a route selector is about choosing train routes, and right-of-way refers to the track area; none describe the warning method used to mark de-energized equipment.
