Under which condition must employees report malfunctioning automatic warning devices?

Employees must report malfunctioning automatic warning devices immediately upon noticing the malfunction to ensure safety and proper operational procedures. These devices are critical for alerting both train crew and nearby personnel of potential hazards or the presence of trains, thereby preventing accidents and enhancing safety within railway operations. Timely reporting allows for prompt maintenance or repairs, which can prevent further complications or dangerous situations.

In the context of railway safety protocols, immediate action is essential. Delaying the report until the end of a shift or day could lead to oversights and increase the risk of incidents. This immediacy in reporting malfunctioning devices underscores the importance of vigilance and adherence to safety standards by all employees in the railroad environment.
