What type of documentation is required when authority limits overlap between two employees?

When authority limits overlap between two employees, the documentation required is a Working Limits Form. This form is essential for ensuring clear communication and safety among employees, especially when they may be operating in the same area or under similar work parameters. The Working Limits Form serves to define the specific boundaries and conditions under which each employee is authorized to work.

It plays a critical role in maintaining safety protocols by detailing the limits of each worker's authority, preventing any potential conflicts or misunderstandings that could lead to dangerous situations on the railway. By using the Working Limits Form, employees can easily reference the established parameters, which helps ensure that all personnel on-site are aware of their respective authorities and responsibilities.

Other types of documentation, while related to communication and safety, do not specifically address the need for clarity when authority limits overlap. The Track Bulletin Form B and Form B Limits Summary might contain relevant information regarding work zones or procedures, but they do not specifically focus on the situation of overlapping authority limits. Similarly, an Authority Limits Log is more focused on tracking individual authorities rather than addressing the specific issue of overlap. Therefore, the Working Limits Form is the appropriate tool to manage these circumstances effectively.
