What is the primary purpose of a guardrail system?

The primary purpose of a guardrail system is to prevent falls from elevated surfaces. Guardrails are crucial safety features in construction and other elevated work environments, serving as a physical barrier that reduces the risk of workers falling off edges, balconies, roofs, or other high areas. The presence of guardrails helps to ensure that workers maintain their balance and stay within the designated safe working area, thereby significantly minimizing the risk of serious injuries or fatalities associated with falls.

While guardrails are not designed for other functions—such as storing tools, providing a walking surface, or supporting scaffolding—their role in promoting safety and preventing accidents on construction sites is their most essential characteristic.
