When mechanical equipment is not used, how far should the warning line be from the roof edge?

The correct distance for the warning line from the roof edge is 6 feet. This guideline is established to ensure adequate safety measures are in place for workers performing tasks on roofs. The warning line serves as a visual barrier to help prevent falls, which are a significant hazard when working at heights.

By positioning the warning line 6 feet from the edge, it provides a buffer zone that allows workers to remain aware of their proximity to the edge while reducing the risk of accidental falls. This distance is based on safety regulations intended to protect workers and promote awareness of their surroundings when working on elevated surfaces. It is essential for creating a safe working environment and is often implemented in conjunction with other fall protection measures (such as guardrails or personal fall arrest systems) to ensure comprehensive safety protocols are followed on construction sites.
