What is the minimum height for guardrails on scaffolding?

The minimum height for guardrails on scaffolding is set at 42 inches. This height is established to provide adequate protection for workers from falls while ensuring that the guardrail is high enough to be effective without being too cumbersome for workers who may need to lean or reach over the edge.

The 42-inch requirement is part of the safety regulations outlined by OSHA (Occupational Safety and Health Administration) and is designed to help prevent serious injuries that can occur when workers are elevated and not adequately protected. Guardrails at this height are sufficient to intercept most individuals who might fall over the edge, thereby significantly reducing the risk of a fall-related injury. This regulation reflects the importance of safety standards in the construction industry, helping ensure a secure working environment for all personnel involved.
