What is the requirement for an equipped flagger during the nighttime?

The requirement for an equipped flagger during nighttime operations is to wear a fluorescent vest, shirt, or jacket. This visibility measure is crucial for safety because it makes the flagger easily identifiable to train crews and other personnel in low-light conditions. Properly equipped visibility gear helps ensure that the flagger can be seen from a distance, thereby reducing the risk of accidents and enhancing the overall safety of railroad operations during the night.

The use of fluorescent materials is designed to reflect light, further increasing visibility. This reflects the emphasis on safety protocols within railroad operations, ensuring that all personnel are as visible as possible to avoid mishaps. Visibility is essential not only for the flagger's protection but also for the safety of train crews and any other workers on or near the tracks.
