Warning lines shall be erected at least how far from the roof edge when no mechanical equipment is being used?

Explanation:
The main idea is establishing a safe boundary on a roof when fall protection isn’t being used. A warning line creates a visible buffer between workers and the edge to prevent accidental slips over the edge. The rule sets this boundary at a minimum distance of six feet from the roof edge so workers have enough space to move and perform tasks without stepping into the fall hazard. If no mechanical equipment is involved, this six-foot distance is required to keep operations safely away from the edge. Distances like four feet would shrink the buffer, while eight or twelve feet are larger than needed for the minimum requirement. Six feet is the minimum distance mandated.
