What must the lone worker do at the beginning of each duty period?

At the beginning of each duty period, it is critical for the lone worker to communicate with the supervisor or train dispatcher. This communication serves as a vital safety measure, ensuring that the worker is informed about the latest operational updates, safety protocols, and any relevant information that may affect their duties.

By establishing this line of communication, the lone worker can confirm their understanding of their assignments, clarify any potential concerns, and report their status, which is particularly important in a railroad environment where safety and coordination among various team members are paramount. This step helps mitigate risks associated with working alone and ensures that proper protocols are followed from the outset of the duty period.

The other options, while important in different contexts, do not specifically address the essential communication requirement set for lone workers at the start of their shifts. Meeting with team members, conducting safety drills, or inspecting all equipment may be part of larger operational procedures, but they do not substitute the critical need for early communication with supervisors or dispatchers.
