Who may remove blue signals?

• A. They may only be removed by an employee of the same craft or group that displayed them.
• B. Any employee may remove blue signals after signaling to move.
• C. A supervisor may remove them anytime.
• D. The conductor may remove them after the crew completes a task.

Answer: (A)

Blue signals are protection devices used to safeguard workers on or near the track. They can only be removed by someone from the same craft or group that displayed them, meaning the person who placed the blue signal or another worker in that same specialty who has authority to clear it. This requirement ensures the crew that did the work verifies the area is safe and that it's appropriate to proceed, preventing unprotected movement that could endanger crews. Allowing any employee to remove blue signals or letting a supervisor or conductor remove them without regard to the specific work and safety status could lead to unsafe conditions. The rule keeps removal tied to the worker who understands exactly what was protected and what remains safe to clear.
