What is the standard height for top rails in a guardrail system?

The standard height for top rails in a guardrail system is set at 42 inches. This height is designed to provide effective protection for workers, helping to prevent falls from elevated surfaces. The 42-inch standard is widely recognized and adopted in various safety regulations, ensuring that guardrails are adequately positioned to offer a secure barrier without unnecessarily obstructing views or access. This height is considered sufficient to deter individuals from leaning over or attempting to climb over the guardrail, thereby enhancing safety in construction and maintenance environments. The established standard has been backed by research on fall protection, empowering construction managers and safety officers to maintain a safe working environment. The other mentioned heights do not align with the universal safety guidelines established for guardrail systems.
