The reason why scaffolding systems are not classified as a type of fall protection for unprotected sides or edges lies in their primary function and design. Scaffolding is primarily used as a temporary structure that provides a platform for workers to perform tasks at height, rather than serving as a protective measure against falls.

In contrast, guardrail systems, safety net systems, and personal fall arrest systems are specifically designed to prevent workers from falling off edges or elevated surfaces. Guardrails physically block individuals from accidentally stepping off the edge, while safety nets capture falling workers. Personal fall arrest systems are worn by workers and are designed to stop a fall before hitting the ground or a lower level.

Thus, while scaffolding provides a means to carry out work at heights, it does not function as a dedicated fall protection system for unprotected sides or edges and therefore is not included in that category. This understanding is crucial for ensuring safety on construction sites and adhering to safety regulations.
