What type of fall protection system is required when working on a vertical surface?

When working on a vertical surface, a Positioning Device System is particularly appropriate because it allows a worker to be supported at the work level while providing hands-free operation. This system is designed to keep the worker in an upright position at a location where they can perform tasks with both hands, while still preventing them from falling to a lower level.

Positioning Device Systems include the use of straps or lanyards that secure the worker to the structure they are working on, thereby allowing for both safety and mobility for tasks. The correct functionality of this system helps maintain stability and reduces the risk of falling, making it ideal for scenarios involving vertical surfaces, such as pole climbing, working on ladders, or performing tasks on scaffolds.

While other systems like Fall Arrest Systems are crucial for preventing falls from significant heights, their primary function is to catch a falling worker rather than provide support during work. Guardrail Systems also provide a safety barrier but might not be feasible or effective in all vertical scenarios. Rescue Systems, on the other hand, are not preventive measures but are designed to respond if an accident occurs. This context highlights why a Positioning Device System is specifically suited for the task at hand.
