Instead, OSHA requires a physical barrier between the worker and the leading edge. This decision was made after careful consideration, prioritizing worker safety and the visibility of warning lines at a height between 34 to 39 inches. This height ensures effective warning for workers approaching designated areas, even when equipment or objects are nearby, minimizing potential hazards and promoting a secure work environment. The primary issue with painted lines is that they disappear when covered with now, dust, or debris.29'
