Hi, my name is Lisa Rhone from the United States. I would like to share my experience with the warning line system. A warning line system is a passive fall protection solution used to mark off designated areas on rooftops or construction sites where fall hazards exist. Consisting of flags or ropes attached to stanchions, it visually alerts workers to stay within safe zones. While it doesn't physically prevent falls, the warning line system serves as a clear boundary and helps comply with OSHA regulations, enhancing safety during work near roof edges or unprotected areas.
