What is the primary action required of employees when working within established working limits?

The primary action required of employees when working within established working limits is to ensure all movements are clear of the limits. This is crucial for maintaining safety and operational efficiency. By verifying that all movements do not encroach upon the established working limits, employees help to prevent accidents and collisions, ensuring that trains operate safely within designated areas. This proactive measure protects both personnel and equipment and upholds the overall safety standards of railway operations.

In a rail environment, established working limits are set to delineate zones where specific work or train movements can occur. Adhering to these limits prevents unauthorized or unsafe actions that could lead to serious incidents. As such, ensuring that all movements are clear reflects a foundational responsibility of railway employees in safeguarding operations while complying with operational protocols.
