Which term indicates a safety warning used to indicate that equipment has been de-energized for maintenance, repair, or other reasons?

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

Answer: (B)

The main idea here is recognizing the safety warning that tells others a piece of equipment has been shut off for maintenance and must not be operated. A red tag is the visual signal used to indicate the energy sources are isolated and the equipment is de-energized while work is done. It stays in place until the authorized person who performed the maintenance removes it, ensuring no one accidentally re-energizes the system. Panic brake relates to an emergency stop function, which is about stopping a train in a crisis, not about maintenance tagging. Route selector is a control that changes which track or route a train will follow. Right-of-way refers to the legal area where trains have priority on the track. These are not warnings about de-energized equipment, so they don’t fit as well as the red tag.
