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

The correct answer includes a combination of fall protection devices that are specifically designed to ensure safety when working on a low slope roof greater than 50 feet in width. A guardrail is a crucial component, as it provides a permanent barrier that can prevent workers from falling off the edge of the roof.

In addition, a safety net can be utilized as a secondary measure, providing an additional layer of protection in case a worker does fall and offers a way to catch them before hitting the ground. The personal fall arrest system is also essential, as it directly restraints a worker to prevent a fall when working at heights. Finally, a warning line serves as a visual alert for workers to maintain a safe distance from the edge of the roof, helping to minimize the risk of accidental falls.

The combination of these devices is necessary in the context of a low slope roof over 50 feet because they collectively enhance the safety of workers by addressing different aspects of fall prevention and control. Thus, having a comprehensive set of precautionary measures is vital in such scenarios to comply with safety regulations and safeguard workers effectively.
