Which fall protection devices are required for a low slope roof greater than 50 ft in width?

For a low slope roof that is greater than 50 feet in width, a comprehensive range of fall protection devices is required to ensure the safety of workers. This requirement is in place due to the increased risk of falls associated with working on such surfaces.

The inclusion of a guardrail provides a physical barrier that can prevent a worker from falling off the edge of the roof. Complementing this, safety nets serve as a secondary measure to catch any worker who might slip or fall, providing additional safety beyond the guardrails. A personal fall arrest system is essential as it offers personal protection to the worker, anchoring them securely and stopping any fall before impact. Finally, a warning line system indicates the area where workers should exercise caution, serving as a visual alert for employees about the potential fall hazard.

This combination of devices creates a layered approach to fall protection, adhering to safety standards that aim to minimize the risk of injury in construction scenarios. The other options do not encompass the full spectrum of protection necessary for such a potential hazard area, which is why they do not meet the requirements for a low slope roof of this size.
