It also requires a knee rail and a handrail, with intermediate vertical members spaced to prevent gaps larger than 180 mm, ensuring safety around machinery or elevated platforms .Additional ConsiderationsToe boards: At least 3.5 inches tall to prevent objects from falling.Material and strength: Guardrails must be constructed from materials capable of withstanding heavy impacts without deflection that compromises safety .Special conditions: If employees use stilts or elevated equipment, the top rail height should be increased accordingly .
