Employees equipped with flagging equipment must:

• A. Go out at least the distance prescribed by the table in part (A) of this rule
• B. Display a lighted fusee if they see or hear a train approaching
• C. Give a Stop Signal to approaching trains that may be affected
• D. All of the above

Answer: (D)

Flagging protection hinges on establishing a visible warning and clear train movement instructions around a work area. You must position yourself at least the distance prescribed from the danger point so trains have enough time to observe the warning and respond. If you can see or hear a train approaching, you must display a lighted fusee to make the warning clearly visible in all conditions. You also have to give a Stop Signal to approaching trains that may be affected, directing them to stop and not proceed into the protected area until you indicate it’s safe. All three actions work together to fully protect both the workers and the trains, so doing all of them is required.
