When working on roofs, what methods must be employed for employee safety?

The use of guardrail systems, safety net systems, or personal fall arrest systems is a comprehensive approach to ensuring employee safety when working on roofs. These methods are specifically designed to minimize the risk of falls, which are one of the leading causes of fatalities in the construction industry.

Guardrail systems are physical barriers installed at the edge of a roof that prevent workers from falling off. They are required in certain situations where workers are exposed to a fall hazard. Safety net systems offer a fall protection strategy by catching workers if they fall, providing another layer of safety. Personal fall arrest systems, which include harnesses and lanyards, are critical for preventing a fall once it occurs. By utilizing these systems together, employers can create a safer working environment on rooftops and adhere to OSHA regulations designed to protect workers from fall hazards.

While harnesses are indeed an essential component of fall protection, relying solely on them does not encompass the full spectrum of safety measures required for roof work. Similarly, although installing permanent staircases can enhance safety for accessing roofs, it does not directly address the risk of falls while working on the roof itself. Prohibiting work during high winds is a prudent safety measure, but it does not provide a method to protect workers when conditions allow
