Warning lines serve as an important safety measure when working at heights, particularly on roofs. They are designed to warn workers about the proximity to the edge of a roof where there is a risk of falling. The established guideline for the placement of warning lines, when no mechanical equipment is being used, is to erect them 6 feet from the roof edge. This distance provides an effective barrier to help prevent accidental falls and ensures that workers are made aware of their location in relation to the edge.

The 6-foot requirement allows adequate space for workers to perform their tasks safely while minimizing the risk of unintended movement towards the roof edge. It creates a visual cue for workers, thereby enhancing safety practices and reducing the likelihood of accidents.

Understanding these guidelines is crucial for maintaining safety on job sites, particularly in construction or similar environments where fall hazards are prevalent.
