OSHA regulations state that any serviceable equipment within 15 feet of the roof edge need to be guarded with fall protection devices. That means utilizing railing barrier systems, nets, anchor points etc. But other areas on a roof between this serviceable equipment should be guarded warning people they are entering restricted space. That’s where warning line systems can fit the bill. While not considered fall protection devices, they are considered a visual warning for restricted spaces. Safety Rail Company offers a number of different options ranging from temporary to long-term permanent installations.
